Corbits inference and login

Codex and xAI are built on openai-responses and oauth-core. Codex depends on the ChatGPT backend and is the most fragile.

Wire an adapter in process

import { createDependencies, runInference } from "@intx/inference";
import {
  createOpenAIResponsesAdapter,
  OPENAI_RESPONSES_PROVIDER,
} from "@corbits/openai-responses";

const deps = createDependencies({
  has: (p) => p === OPENAI_RESPONSES_PROVIDER,
  resolve: (source, quirks) => createOpenAIResponsesAdapter(source, quirks),
});
const source = {
  id: "openai",
  provider: OPENAI_RESPONSES_PROVIDER,
  baseURL: "https://api.openai.com/v1",
  credentialId: "OPENAI_API_KEY",
  model: "gpt-5-mini",
};
// runInference({ deps, source, turns, nextSeq, readMaterial: (id) => ({ secret: process.env[id]! }) })

Wire an adapter in a sidecar

SIDECAR_ADAPTER_MANIFEST='[{"provider":"ollama","specifier":"@corbits/ollama-adapter","export":"createOllamaAdapter"}]'

The hub forwards this variable to sidecars it spawns. Codex uses createCodexResponsesAdapter with provider id codex. Ollama on /v1/messages uses the export createOllamaAnthropicAdapter.

Per-package notes

• Codex: name your host with CodexQuirks { productName, environmentTagName }. Pass the account id as providerOptions[CODEX_ACCOUNT_ID_OPTION]. createDependencies binds global fetch, so build deps by hand to install withCodexContentTypeRepair.
• xAI: for API keys use XAI_API_KEY_BASE_URL (https://api.x.ai/v1). For the OAuth login use XAI_OAUTH_PROXY_BASE_URL and pass the user id option.
• Ollama: set reasoning per model in mixed fleets (Ollama rejects reasoning_effort on non-reasoning models). It ignores num_ctx on /v1, so start the server with OLLAMA_CONTEXT_LENGTH.
• oauth-core: loginWithProvider(...) for CLIs. On the hub, mountOAuthLogin and createOAuthTokenRefresher from @corbits/oauth-core/hub. A provider is { oauthConfig, exchange, refresh }, supplied by a package like codex or xai.
• Peer ranges: codex and xai currently peer on oauth-core@^0.2.0 and openai-responses@^0.2.0, but oauth-core is 0.3.0. Check peer warnings before installing them together.
