Reusable model API contracts, provider adapters, and streaming primitives from OpenClaw. The package supports isolated runtime instances; importing it does not register providers globally.

import { createLlmRuntime } from "@openclaw/ai";
import { registerBuiltInApiProviders } from "@openclaw/ai/providers";

const runtime = createLlmRuntime();
registerBuiltInApiProviders(runtime.registry);

Provider-neutral contracts, validation, diagnostics, and event streams are available from the package root and focused subpaths such as @openclaw/ai/event-stream, @openclaw/ai/transports, and @openclaw/ai/validation. No second OpenClaw runtime package is required.

Provider ids, credentials, model catalogs, retries, and failover remain application concerns. OpenClaw supplies those policies around this package. Host policy (request fetch guarding, secret redaction, strict-tool defaults, provider plugin hooks, and diagnostics logging) can be injected with configureAiTransportHost; the defaults are inert. Node callers that need runtime-local policy can use createNodeLlmRuntime; it preserves that host across provider work without replacing the process default. createLlmRuntime continues to use the process-default host.

The explicit @openclaw/ai/internal/anthropic, google-model-family, openai, openai-completions-compat, openai-responses-payload-policy, retry-after, runtime, shared, and tool-schema subpaths exist for the OpenClaw application itself. They carry no semver guarantee and can change or disappear in any release; do not depend on them outside OpenClaw.
