Local is doable, but OpenClaw expects large context + strong defenses against prompt injection. Small cards truncate context and leak safety. Aim high: ≥2 maxed-out Mac Studios or equivalent GPU rig (~$30k+). A single 24 GB GPU works only for lighter prompts with higher latency. Use the largest / full-size model variant you can run; aggressively quantized or “small” checkpoints raise prompt-injection risk (see Security). If you want the lowest-friction local setup, start with LM Studio or Ollama andDocumentation Index

openclaw onboard. This page is the opinionated guide for higher-end local stacks and custom OpenAI-compatible local servers.
Recommended: LM Studio + large local model (Responses API)
Best current local stack. Load a large model in LM Studio (for example, a full-size Qwen, DeepSeek, or Llama build), enable the local server (defaulthttp://127.0.0.1:1234), and use Responses API to keep reasoning separate from final text.
- Install LM Studio: https://lmstudio.ai
- In LM Studio, download the largest model build available (avoid “small”/heavily quantized variants), start the server, confirm
http://127.0.0.1:1234/v1/modelslists it. - Replace
my-local-modelwith the actual model ID shown in LM Studio. - Keep the model loaded; cold-load adds startup latency.
- Adjust
contextWindow/maxTokensif your LM Studio build differs. - For WhatsApp, stick to Responses API so only final text is sent.
models.mode: "merge" so fallbacks stay available.
Hybrid config: hosted primary, local fallback
Local-first with hosted safety net
Swap the primary and fallback order; keep the same providers block andmodels.mode: "merge" so you can fall back to Sonnet or Opus when the local box is down.
Regional hosting / data routing
- Hosted MiniMax/Kimi/GLM variants also exist on OpenRouter with region-pinned endpoints (e.g., US-hosted). Pick the regional variant there to keep traffic in your chosen jurisdiction while still using
models.mode: "merge"for Anthropic/OpenAI fallbacks. - Local-only remains the strongest privacy path; hosted regional routing is the middle ground when you need provider features but want control over data flow.
Other OpenAI-compatible local proxies
MLX (mlx_lm.server), vLLM, SGLang, LiteLLM, OAI-proxy, or custom
gateways work if they expose an OpenAI-style /v1/chat/completions
endpoint. Use the Chat Completions adapter unless the backend explicitly
documents /v1/responses support. Replace the provider block above with your
endpoint and model ID:
api is omitted on a custom provider with a baseUrl, OpenClaw defaults to
openai-completions. Loopback endpoints such as 127.0.0.1 are trusted
automatically; LAN, tailnet, and private DNS endpoints still need
request.allowPrivateNetwork: true.
The models.providers.<id>.models[].id value is provider-local. Do not
include the provider prefix there. For example, an MLX server started with
mlx_lm.server --model mlx-community/Qwen3-30B-A3B-6bit should use this
catalog id and model ref:
models.providers.mlx.models[].id: "mlx-community/Qwen3-30B-A3B-6bit"agents.defaults.model.primary: "mlx/mlx-community/Qwen3-30B-A3B-6bit"
input: ["text", "image"] on local or proxied vision models so image
attachments are injected into agent turns. Interactive custom-provider
onboarding infers common vision model IDs and asks only for unknown names.
Non-interactive onboarding uses the same inference; use --custom-image-input
for unknown vision IDs or --custom-text-input when a known-looking model is
text-only behind your endpoint.
Keep models.mode: "merge" so hosted models stay available as fallbacks.
Use models.providers.<id>.timeoutSeconds for slow local or remote model
servers before raising agents.defaults.timeoutSeconds. The provider timeout
applies only to model HTTP requests, including connect, headers, body streaming,
and the total guarded-fetch abort.
For custom OpenAI-compatible providers, persisting a non-secret local marker such as
apiKey: "ollama-local" is accepted when baseUrl resolves to loopback, a private LAN, .local, or a bare hostname. OpenClaw treats it as a valid local credential instead of reporting a missing key. Use a real value for any provider that accepts a public hostname./v1 backends:
- OpenClaw treats these as proxy-style OpenAI-compatible routes, not native OpenAI endpoints
- native OpenAI-only request shaping does not apply here: no
service_tier, no Responsesstore, no OpenAI reasoning-compat payload shaping, and no prompt-cache hints - hidden OpenClaw attribution headers (
originator,version,User-Agent) are not injected on these custom proxy URLs
-
Some servers accept only string
messages[].contenton Chat Completions, not structured content-part arrays. Setmodels.providers.<provider>.models[].compat.requiresStringContent: truefor those endpoints. -
Some local models emit standalone bracketed tool requests as text, such as
[tool_name]followed by JSON and[END_TOOL_REQUEST]. OpenClaw promotes those into real tool calls only when the name exactly matches a registered tool for the turn; otherwise the block is treated as unsupported text and is hidden from user-visible replies. - If a model emits JSON, XML, or ReAct-style text that looks like a tool call but the provider did not emit a structured invocation, OpenClaw leaves it as text and logs a warning with the run id, provider/model, detected pattern, and tool name when available. Treat that as provider/model tool-call incompatibility, not a completed tool run.
-
If tools appear as assistant text instead of running, for example raw JSON,
XML, ReAct syntax, or an empty
tool_callsarray in the provider response, first verify the server is using a tool-call-capable chat template/parser. For OpenAI-compatible Chat Completions backends whose parser works only when tool use is forced, set a per-model request override instead of relying on text parsing:Use this only for models/sessions where every normal turn should call a tool. It overrides OpenClaw’s default proxy value oftool_choice: "auto". Replacelocal/my-local-modelwith the exact provider/model ref shown byopenclaw models list. -
If a custom OpenAI-compatible model accepts OpenAI reasoning efforts beyond
the built-in profile, declare them on the model compat block. Adding
"xhigh"here makes/think xhigh, session pickers, Gateway validation, andllm-taskvalidation expose the level for that configured provider/model ref: -
Some smaller or stricter local backends are unstable with OpenClaw’s full
agent-runtime prompt shape, especially when tool schemas are included. First
verify the provider path with the lean local probe:
To verify the Gateway route without the full agent prompt shape, use the Gateway model probe instead:Both local and Gateway model probes send only the supplied prompt. The Gateway probe still validates Gateway routing, auth, and provider selection, but it intentionally skips prior session transcript, AGENTS/bootstrap context, context-engine assembly, tools, and bundled MCP servers. If that succeeds but normal OpenClaw agent turns fail, first try
agents.defaults.experimental.localModelLean: trueto drop heavyweight default tools likebrowser,cron, andmessage; this is an experimental flag, not a stable default-mode setting. See Experimental Features. If that still fails, trymodels.providers.<provider>.models[].compat.supportsTools: false. - If the backend still fails only on larger OpenClaw runs, the remaining issue is usually upstream model/server capacity or a backend bug, not OpenClaw’s transport layer.
Troubleshooting
- Gateway can reach the proxy?
curl http://127.0.0.1:1234/v1/models. - LM Studio model unloaded? Reload; cold start is a common “hanging” cause.
- Local server says
terminated,ECONNRESET, or closes the stream mid-turn? OpenClaw records a low-cardinalitymodel.call.error.failureKindplus the OpenClaw process RSS/heap snapshot in diagnostics. For LM Studio/Ollama memory pressure, match that timestamp against the server log or macOS crash / jetsam log to confirm whether the model server was killed. - OpenClaw derives context-window preflight thresholds from the detected model window, or from the uncapped model window when
agents.defaults.contextTokenslowers the effective window. It warns below 20% with an 8k floor. Hard blocks use the 10% threshold with a 4k floor, capped to the effective context window so oversized model metadata cannot reject an otherwise valid user cap. If you hit that preflight, raise the server/model context limit or choose a larger model. - Context errors? Lower
contextWindowor raise your server limit. - OpenAI-compatible server returns
messages[].content ... expected a string? Addcompat.requiresStringContent: trueon that model entry. - Direct tiny
/v1/chat/completionscalls work, butopenclaw infer model run --localfails on Gemma or another local model? Check the provider URL, model ref, auth marker, and server logs first; localmodel rundoes not include agent tools. If localmodel runsucceeds but larger agent turns fail, reduce the agent tool surface withlocalModelLeanorcompat.supportsTools: false. - Tool calls show up as raw JSON/XML/ReAct text, or the provider returns an
empty
tool_callsarray? Do not add a proxy that blindly converts assistant text into tool execution. Fix the server chat template/parser first. If the model only works when tool use is forced, add the per-modelparams.extra_body.tool_choice: "required"override above and use that model entry only for sessions where a tool call is expected on every turn. - Safety: local models skip provider-side filters; keep agents narrow and compaction on to limit prompt injection blast radius.
