summary: "Use OpenAI via API keys or Codex subscription in OpenClaw"
read_when:
- You want to use OpenAI models in OpenClaw
- You want Codex subscription auth instead of API keys
- You need stricter GPT-5 agent execution behavior
title: "OpenAI"
---
OpenAI provides developer APIs for GPT models. OpenClaw supports three OpenAI-family routes. The model prefix selects the route:
- **API key** — direct OpenAI Platform access with usage-based billing (`openai/*` models)
- **Codex subscription through PI** — ChatGPT/Codex sign-in with subscription access (`openai-codex/*` models)
- **Codex app-server harness** — native Codex app-server execution (`openai/*` models plus `agents.defaults.embeddedHarness.runtime: "codex"`)
OpenAI explicitly supports subscription OAuth usage in external tools and workflows like OpenClaw.
Provider, model, runtime, and channel are separate layers. If those labels are
getting mixed together, read [Agent runtimes](/concepts/agent-runtimes) before
changing config.
## Quick choice
| Goal | Use | Notes |
| --------------------------------------------- | -------------------------------------------------------- | ---------------------------------------------------------------------------- |
| Direct API-key billing | `openai/gpt-5.5` | Set `OPENAI_API_KEY` or run OpenAI API-key onboarding. |
| GPT-5.5 with ChatGPT/Codex subscription auth | `openai-codex/gpt-5.5` | Default PI route for Codex OAuth. Best first choice for subscription setups. |
| GPT-5.5 with native Codex app-server behavior | `openai/gpt-5.5` plus `embeddedHarness.runtime: "codex"` | Forces the Codex app-server harness for that model ref. |
| Image generation or editing | `openai/gpt-image-2` | Works with either `OPENAI_API_KEY` or OpenAI Codex OAuth. |
| Transparent-background images | `openai/gpt-image-1.5` | Use `outputFormat=png` or `webp` and `openai.background=transparent`. |
GPT-5.5 is available through both direct OpenAI Platform API-key access and
subscription/OAuth routes. Use `openai/gpt-5.5` for direct `OPENAI_API_KEY`
traffic, `openai-codex/gpt-5.5` for Codex OAuth through PI, or
`openai/gpt-5.5` with `embeddedHarness.runtime: "codex"` for the native Codex
app-server harness.
Enabling the OpenAI plugin, or selecting an `openai-codex/*` model, does not
enable the bundled Codex app-server plugin. OpenClaw enables that plugin only
when you explicitly select the native Codex harness with
`embeddedHarness.runtime: "codex"` or use a legacy `codex/*` model ref.
## OpenClaw feature coverage
| OpenAI capability | OpenClaw surface | Status |
| ------------------------- | ---------------------------------------------------------- | ------------------------------------------------------ |
| Chat / Responses | `openai/` model provider | Yes |
| Codex subscription models | `openai-codex/` with `openai-codex` OAuth | Yes |
| Codex app-server harness | `openai/` with `embeddedHarness.runtime: codex` | Yes |
| Server-side web search | Native OpenAI Responses tool | Yes, when web search is enabled and no provider pinned |
| Images | `image_generate` | Yes |
| Videos | `video_generate` | Yes |
| Text-to-speech | `messages.tts.provider: "openai"` / `tts` | Yes |
| Batch speech-to-text | `tools.media.audio` / media understanding | Yes |
| Streaming speech-to-text | Voice Call `streaming.provider: "openai"` | Yes |
| Realtime voice | Voice Call `realtime.provider: "openai"` / Control UI Talk | Yes |
| Embeddings | memory embedding provider | Yes |
## Getting started
Choose your preferred auth method and follow the setup steps.
**Best for:** direct API access and usage-based billing.
Create or copy an API key from the [OpenAI Platform dashboard](https://platform.openai.com/api-keys).
```bash
openclaw onboard --auth-choice openai-api-key
```
Or pass the key directly:
```bash
openclaw onboard --openai-api-key "$OPENAI_API_KEY"
```
```bash
openclaw models list --provider openai
```
### Route summary
| Model ref | Route | Auth |
|-----------|-------|------|
| `openai/gpt-5.5` | Direct OpenAI Platform API | `OPENAI_API_KEY` |
| `openai/gpt-5.4-mini` | Direct OpenAI Platform API | `OPENAI_API_KEY` |
`openai/*` is the direct OpenAI API-key route unless you explicitly force
the Codex app-server harness. Use `openai-codex/*` for Codex OAuth through
the default PI runner, or use `openai/gpt-5.5` with
`embeddedHarness.runtime: "codex"` for native Codex app-server execution.
### Config example
```json5
{
env: { OPENAI_API_KEY: "sk-..." },
agents: { defaults: { model: { primary: "openai/gpt-5.5" } } },
}
```
OpenClaw does **not** expose `openai/gpt-5.3-codex-spark`. Live OpenAI API requests reject that model, and the current Codex catalog does not expose it either.
**Best for:** using your ChatGPT/Codex subscription instead of a separate API key. Codex cloud requires ChatGPT sign-in.
```bash
openclaw onboard --auth-choice openai-codex
```
Or run OAuth directly:
```bash
openclaw models auth login --provider openai-codex
```
For headless or callback-hostile setups, add `--device-code` to sign in with a ChatGPT device-code flow instead of the localhost browser callback:
```bash
openclaw models auth login --provider openai-codex --device-code
```
```bash
openclaw config set agents.defaults.model.primary openai-codex/gpt-5.5
```
```bash
openclaw models list --provider openai-codex
```
### Route summary
| Model ref | Route | Auth |
|-----------|-------|------|
| `openai-codex/gpt-5.5` | ChatGPT/Codex OAuth through PI | Codex sign-in |
| `openai/gpt-5.5` + `embeddedHarness.runtime: "codex"` | Codex app-server harness | Codex app-server auth |
Keep using the `openai-codex` provider id for auth/profile commands. The
`openai-codex/*` model prefix is also the explicit PI route for Codex OAuth.
It does not select or auto-enable the bundled Codex app-server harness.
### Config example
```json5
{
agents: { defaults: { model: { primary: "openai-codex/gpt-5.5" } } },
}
```
Onboarding no longer imports OAuth material from `~/.codex`. Sign in with browser OAuth (default) or the device-code flow above — OpenClaw manages the resulting credentials in its own agent auth store.
### Status indicator
Chat `/status` shows which model runtime is active for the current session.
The default PI harness appears as `Runtime: OpenClaw Pi Default`. When the
bundled Codex app-server harness is selected, `/status` shows
`Runtime: OpenAI Codex`. Existing sessions keep their recorded harness id, so use
`/new` or `/reset` after changing `embeddedHarness` if you want `/status` to
reflect a new PI/Codex choice.
### Context window cap
OpenClaw treats model metadata and the runtime context cap as separate values.
For `openai-codex/gpt-5.5` through Codex OAuth:
- Native `contextWindow`: `1000000`
- Default runtime `contextTokens` cap: `272000`
The smaller default cap has better latency and quality characteristics in practice. Override it with `contextTokens`:
```json5
{
models: {
providers: {
"openai-codex": {
models: [{ id: "gpt-5.5", contextTokens: 160000 }],
},
},
},
}
```
Use `contextWindow` to declare native model metadata. Use `contextTokens` to limit the runtime context budget.
### Catalog recovery
OpenClaw uses upstream Codex catalog metadata for `gpt-5.5` when it is
present. If live Codex discovery omits the `openai-codex/gpt-5.5` row while
the account is authenticated, OpenClaw synthesizes that OAuth model row so
cron, sub-agent, and configured default-model runs do not fail with
`Unknown model`.
## Image generation
The bundled `openai` plugin registers image generation through the `image_generate` tool.
It supports both OpenAI API-key image generation and Codex OAuth image
generation through the same `openai/gpt-image-2` model ref.
| Capability | OpenAI API key | Codex OAuth |
| ------------------------- | ---------------------------------- | ------------------------------------ |
| Model ref | `openai/gpt-image-2` | `openai/gpt-image-2` |
| Auth | `OPENAI_API_KEY` | OpenAI Codex OAuth sign-in |
| Transport | OpenAI Images API | Codex Responses backend |
| Max images per request | 4 | 4 |
| Edit mode | Enabled (up to 5 reference images) | Enabled (up to 5 reference images) |
| Size overrides | Supported, including 2K/4K sizes | Supported, including 2K/4K sizes |
| Aspect ratio / resolution | Not forwarded to OpenAI Images API | Mapped to a supported size when safe |
```json5
{
agents: {
defaults: {
imageGenerationModel: { primary: "openai/gpt-image-2" },
},
},
}
```
See [Image Generation](/tools/image-generation) for shared tool parameters, provider selection, and failover behavior.
`gpt-image-2` is the default for both OpenAI text-to-image generation and image
editing. `gpt-image-1.5`, `gpt-image-1`, and `gpt-image-1-mini` remain usable as
explicit model overrides. Use `openai/gpt-image-1.5` for transparent-background
PNG/WebP output; the current `gpt-image-2` API rejects
`background: "transparent"`.
For a transparent-background request, agents should call `image_generate` with
`model: "openai/gpt-image-1.5"`, `outputFormat: "png"` or `"webp"`, and
`background: "transparent"`; the older `openai.background` provider option is
still accepted. OpenClaw also protects the public OpenAI and
OpenAI Codex OAuth routes by rewriting default `openai/gpt-image-2` transparent
requests to `gpt-image-1.5`; Azure and custom OpenAI-compatible endpoints keep
their configured deployment/model names.
The same setting is exposed for headless CLI runs:
```bash
openclaw infer image generate \
--model openai/gpt-image-1.5 \
--output-format png \
--background transparent \
--prompt "A simple red circle sticker on a transparent background" \
--json
```
Use the same `--output-format` and `--background` flags with
`openclaw infer image edit` when starting from an input file.
`--openai-background` remains available as an OpenAI-specific alias.
For Codex OAuth installs, keep the same `openai/gpt-image-2` ref. When an
`openai-codex` OAuth profile is configured, OpenClaw resolves that stored OAuth
access token and sends image requests through the Codex Responses backend. It
does not first try `OPENAI_API_KEY` or silently fall back to an API key for that
request. Configure `models.providers.openai` explicitly with an API key,
custom base URL, or Azure endpoint when you want the direct OpenAI Images API
route instead.
If that custom image endpoint is on a trusted LAN/private address, also set
`browser.ssrfPolicy.dangerouslyAllowPrivateNetwork: true`; OpenClaw keeps
private/internal OpenAI-compatible image endpoints blocked unless this opt-in is
present.
Generate:
```
/tool image_generate model=openai/gpt-image-2 prompt="A polished launch poster for OpenClaw on macOS" size=3840x2160 count=1
```
Generate a transparent PNG:
```
/tool image_generate model=openai/gpt-image-1.5 prompt="A simple red circle sticker on a transparent background" outputFormat=png background=transparent
```
Edit:
```
/tool image_generate model=openai/gpt-image-2 prompt="Preserve the object shape, change the material to translucent glass" image=/path/to/reference.png size=1024x1536
```
## Video generation
The bundled `openai` plugin registers video generation through the `video_generate` tool.
| Capability | Value |
| ---------------- | --------------------------------------------------------------------------------- |
| Default model | `openai/sora-2` |
| Modes | Text-to-video, image-to-video, single-video edit |
| Reference inputs | 1 image or 1 video |
| Size overrides | Supported |
| Other overrides | `aspectRatio`, `resolution`, `audio`, `watermark` are ignored with a tool warning |
```json5
{
agents: {
defaults: {
videoGenerationModel: { primary: "openai/sora-2" },
},
},
}
```
See [Video Generation](/tools/video-generation) for shared tool parameters, provider selection, and failover behavior.
## GPT-5 prompt contribution
OpenClaw adds a shared GPT-5 prompt contribution for GPT-5-family runs across providers. It applies by model id, so `openai-codex/gpt-5.5`, `openai/gpt-5.5`, `openrouter/openai/gpt-5.5`, `opencode/gpt-5.5`, and other compatible GPT-5 refs receive the same overlay. Older GPT-4.x models do not.
The bundled native Codex harness uses the same GPT-5 behavior and heartbeat overlay through Codex app-server developer instructions, so `openai/gpt-5.x` sessions forced through `embeddedHarness.runtime: "codex"` keep the same follow-through and proactive heartbeat guidance even though Codex owns the rest of the harness prompt.
The GPT-5 contribution adds a tagged behavior contract for persona persistence, execution safety, tool discipline, output shape, completion checks, and verification. Channel-specific reply and silent-message behavior stays in the shared OpenClaw system prompt and outbound delivery policy. The GPT-5 guidance is always enabled for matching models. The friendly interaction-style layer is separate and configurable.
| Value | Effect |
| ---------------------- | ------------------------------------------- |
| `"friendly"` (default) | Enable the friendly interaction-style layer |
| `"on"` | Alias for `"friendly"` |
| `"off"` | Disable only the friendly style layer |
```json5
{
agents: {
defaults: {
promptOverlays: {
gpt5: { personality: "friendly" },
},
},
},
}
```
```bash
openclaw config set agents.defaults.promptOverlays.gpt5.personality off
```
Values are case-insensitive at runtime, so `"Off"` and `"off"` both disable the friendly style layer.
Legacy `plugins.entries.openai.config.personality` is still read as a compatibility fallback when the shared `agents.defaults.promptOverlays.gpt5.personality` setting is not set.
## Voice and speech
The bundled `openai` plugin registers speech synthesis for the `messages.tts` surface.
| Setting | Config path | Default |
|---------|------------|---------|
| Model | `messages.tts.providers.openai.model` | `gpt-4o-mini-tts` |
| Voice | `messages.tts.providers.openai.voice` | `coral` |
| Speed | `messages.tts.providers.openai.speed` | (unset) |
| Instructions | `messages.tts.providers.openai.instructions` | (unset, `gpt-4o-mini-tts` only) |
| Format | `messages.tts.providers.openai.responseFormat` | `opus` for voice notes, `mp3` for files |
| API key | `messages.tts.providers.openai.apiKey` | Falls back to `OPENAI_API_KEY` |
| Base URL | `messages.tts.providers.openai.baseUrl` | `https://api.openai.com/v1` |
Available models: `gpt-4o-mini-tts`, `tts-1`, `tts-1-hd`. Available voices: `alloy`, `ash`, `ballad`, `cedar`, `coral`, `echo`, `fable`, `juniper`, `marin`, `onyx`, `nova`, `sage`, `shimmer`, `verse`.
```json5
{
messages: {
tts: {
providers: {
openai: { model: "gpt-4o-mini-tts", voice: "coral" },
},
},
},
}
```
Set `OPENAI_TTS_BASE_URL` to override the TTS base URL without affecting the chat API endpoint.
The bundled `openai` plugin registers batch speech-to-text through
OpenClaw's media-understanding transcription surface.
- Default model: `gpt-4o-transcribe`
- Endpoint: OpenAI REST `/v1/audio/transcriptions`
- Input path: multipart audio file upload
- Supported by OpenClaw wherever inbound audio transcription uses
`tools.media.audio`, including Discord voice-channel segments and channel
audio attachments
To force OpenAI for inbound audio transcription:
```json5
{
tools: {
media: {
audio: {
models: [
{
type: "provider",
provider: "openai",
model: "gpt-4o-transcribe",
},
],
},
},
},
}
```
Language and prompt hints are forwarded to OpenAI when supplied by the
shared audio media config or per-call transcription request.
The bundled `openai` plugin registers realtime transcription for the Voice Call plugin.
| Setting | Config path | Default |
|---------|------------|---------|
| Model | `plugins.entries.voice-call.config.streaming.providers.openai.model` | `gpt-4o-transcribe` |
| Language | `...openai.language` | (unset) |
| Prompt | `...openai.prompt` | (unset) |
| Silence duration | `...openai.silenceDurationMs` | `800` |
| VAD threshold | `...openai.vadThreshold` | `0.5` |
| API key | `...openai.apiKey` | Falls back to `OPENAI_API_KEY` |
Uses a WebSocket connection to `wss://api.openai.com/v1/realtime` with G.711 u-law (`g711_ulaw` / `audio/pcmu`) audio. This streaming provider is for Voice Call's realtime transcription path; Discord voice currently records short segments and uses the batch `tools.media.audio` transcription path instead.
The bundled `openai` plugin registers realtime voice for the Voice Call plugin.
| Setting | Config path | Default |
|---------|------------|---------|
| Model | `plugins.entries.voice-call.config.realtime.providers.openai.model` | `gpt-realtime-1.5` |
| Voice | `...openai.voice` | `alloy` |
| Temperature | `...openai.temperature` | `0.8` |
| VAD threshold | `...openai.vadThreshold` | `0.5` |
| Silence duration | `...openai.silenceDurationMs` | `500` |
| API key | `...openai.apiKey` | Falls back to `OPENAI_API_KEY` |
Supports Azure OpenAI via `azureEndpoint` and `azureDeployment` config keys. Supports bidirectional tool calling. Uses G.711 u-law audio format.
## Azure OpenAI endpoints
The bundled `openai` provider can target an Azure OpenAI resource for image
generation by overriding the base URL. On the image-generation path, OpenClaw
detects Azure hostnames on `models.providers.openai.baseUrl` and switches to
Azure's request shape automatically.
Realtime voice uses a separate configuration path
(`plugins.entries.voice-call.config.realtime.providers.openai.azureEndpoint`)
and is not affected by `models.providers.openai.baseUrl`. See the **Realtime
voice** accordion under [Voice and speech](#voice-and-speech) for its Azure
settings.
Use Azure OpenAI when:
- You already have an Azure OpenAI subscription, quota, or enterprise agreement
- You need regional data residency or compliance controls Azure provides
- You want to keep traffic inside an existing Azure tenancy
### Configuration
For Azure image generation through the bundled `openai` provider, point
`models.providers.openai.baseUrl` at your Azure resource and set `apiKey` to
the Azure OpenAI key (not an OpenAI Platform key):
```json5
{
models: {
providers: {
openai: {
baseUrl: "https://.openai.azure.com",
apiKey: "",
},
},
},
}
```
OpenClaw recognizes these Azure host suffixes for the Azure image-generation
route:
- `*.openai.azure.com`
- `*.services.ai.azure.com`
- `*.cognitiveservices.azure.com`
For image-generation requests on a recognized Azure host, OpenClaw:
- Sends the `api-key` header instead of `Authorization: Bearer`
- Uses deployment-scoped paths (`/openai/deployments/{deployment}/...`)
- Appends `?api-version=...` to each request
- Uses a 600s default request timeout for Azure image-generation calls.
Per-call `timeoutMs` values still override this default.
Other base URLs (public OpenAI, OpenAI-compatible proxies) keep the standard
OpenAI image request shape.
Azure routing for the `openai` provider's image-generation path requires
OpenClaw 2026.4.22 or later. Earlier versions treat any custom
`openai.baseUrl` like the public OpenAI endpoint and will fail against Azure
image deployments.
### API version
Set `AZURE_OPENAI_API_VERSION` to pin a specific Azure preview or GA version
for the Azure image-generation path:
```bash
export AZURE_OPENAI_API_VERSION="2024-12-01-preview"
```
The default is `2024-12-01-preview` when the variable is unset.
### Model names are deployment names
Azure OpenAI binds models to deployments. For Azure image-generation requests
routed through the bundled `openai` provider, the `model` field in OpenClaw
must be the **Azure deployment name** you configured in the Azure portal, not
the public OpenAI model id.
If you create a deployment called `gpt-image-2-prod` that serves `gpt-image-2`:
```
/tool image_generate model=openai/gpt-image-2-prod prompt="A clean poster" size=1024x1024 count=1
```
The same deployment-name rule applies to image-generation calls routed through
the bundled `openai` provider.
### Regional availability
Azure image generation is currently available only in a subset of regions
(for example `eastus2`, `swedencentral`, `polandcentral`, `westus3`,
`uaenorth`). Check Microsoft's current region list before creating a
deployment, and confirm the specific model is offered in your region.
### Parameter differences
Azure OpenAI and public OpenAI do not always accept the same image parameters.
Azure may reject options that public OpenAI allows (for example certain
`background` values on `gpt-image-2`) or expose them only on specific model
versions. These differences come from Azure and the underlying model, not
OpenClaw. If an Azure request fails with a validation error, check the
parameter set supported by your specific deployment and API version in the
Azure portal.
Azure OpenAI uses native transport and compat behavior but does not receive
OpenClaw's hidden attribution headers — see the **Native vs OpenAI-compatible
routes** accordion under [Advanced configuration](#advanced-configuration).
For chat or Responses traffic on Azure (beyond image generation), use the
onboarding flow or a dedicated Azure provider config — `openai.baseUrl` alone
does not pick up the Azure API/auth shape. A separate
`azure-openai-responses/*` provider exists; see
the Server-side compaction accordion below.
## Advanced configuration
OpenClaw uses WebSocket-first with SSE fallback (`"auto"`) for both `openai/*` and `openai-codex/*`.
In `"auto"` mode, OpenClaw:
- Retries one early WebSocket failure before falling back to SSE
- After a failure, marks WebSocket as degraded for ~60 seconds and uses SSE during cool-down
- Attaches stable session and turn identity headers for retries and reconnects
- Normalizes usage counters (`input_tokens` / `prompt_tokens`) across transport variants
| Value | Behavior |
|-------|----------|
| `"auto"` (default) | WebSocket first, SSE fallback |
| `"sse"` | Force SSE only |
| `"websocket"` | Force WebSocket only |
```json5
{
agents: {
defaults: {
models: {
"openai/gpt-5.5": {
params: { transport: "auto" },
},
"openai-codex/gpt-5.5": {
params: { transport: "auto" },
},
},
},
},
}
```
Related OpenAI docs:
- [Realtime API with WebSocket](https://platform.openai.com/docs/guides/realtime-websocket)
- [Streaming API responses (SSE)](https://platform.openai.com/docs/guides/streaming-responses)
OpenClaw enables WebSocket warm-up by default for `openai/*` and `openai-codex/*` to reduce first-turn latency.
```json5
// Disable warm-up
{
agents: {
defaults: {
models: {
"openai/gpt-5.5": {
params: { openaiWsWarmup: false },
},
},
},
},
}
```
OpenClaw exposes a shared fast-mode toggle for `openai/*` and `openai-codex/*`:
- **Chat/UI:** `/fast status|on|off`
- **Config:** `agents.defaults.models["/"].params.fastMode`
When enabled, OpenClaw maps fast mode to OpenAI priority processing (`service_tier = "priority"`). Existing `service_tier` values are preserved, and fast mode does not rewrite `reasoning` or `text.verbosity`.
```json5
{
agents: {
defaults: {
models: {
"openai/gpt-5.5": { params: { fastMode: true } },
},
},
},
}
```
Session overrides win over config. Clearing the session override in the Sessions UI returns the session to the configured default.
OpenAI's API exposes priority processing via `service_tier`. Set it per model in OpenClaw:
```json5
{
agents: {
defaults: {
models: {
"openai/gpt-5.5": { params: { serviceTier: "priority" } },
},
},
},
}
```
Supported values: `auto`, `default`, `flex`, `priority`.
`serviceTier` is only forwarded to native OpenAI endpoints (`api.openai.com`) and native Codex endpoints (`chatgpt.com/backend-api`). If you route either provider through a proxy, OpenClaw leaves `service_tier` untouched.
For direct OpenAI Responses models (`openai/*` on `api.openai.com`), the OpenAI plugin's Pi-harness stream wrapper auto-enables server-side compaction:
- Forces `store: true` (unless model compat sets `supportsStore: false`)
- Injects `context_management: [{ type: "compaction", compact_threshold: ... }]`
- Default `compact_threshold`: 70% of `contextWindow` (or `80000` when unavailable)
This applies to the built-in Pi harness path and to OpenAI provider hooks used by embedded runs. The native Codex app-server harness manages its own context through Codex and is configured separately with `agents.defaults.embeddedHarness.runtime`.
Useful for compatible endpoints like Azure OpenAI Responses:
```json5
{
agents: {
defaults: {
models: {
"azure-openai-responses/gpt-5.5": {
params: { responsesServerCompaction: true },
},
},
},
},
}
```
```json5
{
agents: {
defaults: {
models: {
"openai/gpt-5.5": {
params: {
responsesServerCompaction: true,
responsesCompactThreshold: 120000,
},
},
},
},
},
}
```
```json5
{
agents: {
defaults: {
models: {
"openai/gpt-5.5": {
params: { responsesServerCompaction: false },
},
},
},
},
}
```
`responsesServerCompaction` only controls `context_management` injection. Direct OpenAI Responses models still force `store: true` unless compat sets `supportsStore: false`.
For GPT-5-family runs on `openai/*`, OpenClaw can use a stricter embedded execution contract:
```json5
{
agents: {
defaults: {
embeddedPi: { executionContract: "strict-agentic" },
},
},
}
```
With `strict-agentic`, OpenClaw:
- No longer treats a plan-only turn as successful progress when a tool action is available
- Retries the turn with an act-now steer
- Auto-enables `update_plan` for substantial work
- Surfaces an explicit blocked state if the model keeps planning without acting
Scoped to OpenAI and Codex GPT-5-family runs only. Other providers and older model families keep default behavior.
OpenClaw treats direct OpenAI, Codex, and Azure OpenAI endpoints differently from generic OpenAI-compatible `/v1` proxies:
**Native routes** (`openai/*`, Azure OpenAI):
- Keep `reasoning: { effort: "none" }` only for models that support the OpenAI `none` effort
- Omit disabled reasoning for models or proxies that reject `reasoning.effort: "none"`
- Default tool schemas to strict mode
- Attach hidden attribution headers on verified native hosts only
- Keep OpenAI-only request shaping (`service_tier`, `store`, reasoning-compat, prompt-cache hints)
**Proxy/compatible routes:**
- Use looser compat behavior
- Strip Completions `store` from non-native `openai-completions` payloads
- Accept advanced `params.extra_body`/`params.extraBody` pass-through JSON for OpenAI-compatible Completions proxies
- Do not force strict tool schemas or native-only headers
Azure OpenAI uses native transport and compat behavior but does not receive the hidden attribution headers.
