#2429: added cerebras as a model provider.

# Add Cerebras Provider ## Summary Adds Cerebras as a new model provider with support for 6 ultra-fast inference models using their OpenAI-compatible API at `https://api.cerebras.ai/v1`. Also they have a free tier of about 1M tokens a day, potentially allowing us to run clawdbot for free ( for some while ). ## Changes - ✅ Added Cerebras provider configuration with 6 models: - `llama3.1-8b` (default) - `llama-3.3-70b` - `gpt-oss-120b` - `qwen-3-32b` - `qwen-3-235b-a22b-instruct-2507` - `zai-glm-4.7` - ✅ Interactive onboarding support (`clawdbot onboard --auth-choice cerebras-api-key`) - ✅ Non-interactive CLI flag (`--cerebras-api-key`) - ✅ Documentation for setup and usage ## Files Modified - `src/agents/models-config.providers.ts` - Provider configuration and model catalog - `src/commands/onboard-auth.credentials.ts` - Credential management - `src/commands/onboard-auth.config-core.ts` - Configuration helpers - `src/commands/onboard-auth.ts` - Exported auth functions - `src/commands/onboard-types.ts` - Type definitions - `src/cli/program/register.onboard.ts` - CLI flag support - `src/commands/auth-choice.apply.api-providers.ts` - Interactive auth handler - `src/commands/onboard-non-interactive/local/auth-choice.ts` - Non-interactive auth handler - `src/commands/auth-choice-options.ts` - Menu options and display - `docs/providers/cerebras.md` - Provider documentation - `docs/providers/index.md` - Provider index - `docs/concepts/model-providers.md` - Model provider overview ## Testing - [x] Build passes (`pnpm build`) - [x] Lint passes (`pnpm lint`) - [x] Tests pass (`pnpm test`) - [x] Cerebras appears in interactive onboarding menu - [x] CLI flag `--cerebras-api-key` works - [x] Live API test with `CEREBRAS_API_KEY` From the interactive onboarding form we can select cerebras as a model provider and use this awesome tool. <!-- greptile_comment --> <h2>Greptile Overview</h2> <h3>Greptile Summary</h3> Adds a new Cerebras model provider using an OpenAI-compatible API, including a model catalog, default model selection, and onboarding support (interactive and non-interactive) for storing a Cerebras API key and applying provider defaults. This integrates with the existing provider-resolution flow (`resolveImplicitProviders`), onboarding config helpers (`apply*Config`), and the auth-choice selection system used by both interactive prompts and CLI flags. <h3>Confidence Score: 2/5</h3> - This PR is not safe to merge as-is due to onboarding regressions that can break auth selection and non-interactive configuration. - Cerebras provider additions are straightforward, but `buildAuthChoiceOptions` appears to no longer populate choices (breaking interactive onboarding), and the new `--cerebras-api-key` flag is not wired through to `onboard()` so non-interactive onboarding won’t pick it up. There is also a breaking change removing `gateway-auth off` that may invalidate existing configs/scripts if not fully handled elsewhere. - src/commands/auth-choice-options.ts, src/cli/program/register.onboard.ts, src/commands/onboard-types.ts <!-- greptile_other_comments_section --> _{(2/5) Greptile learns from your feedback when you react with thumbs up/down!} **Context used:** - Context from `dashboard` - CLAUDE.md ([source](https://app.greptile.com/review/custom-context?memory=fd949e91-5c3a-4ab5-90a1-cbe184fd6ce8)) - Context from `dashboard` - AGENTS.md ([source](https://app.greptile.com/review/custom-context?memory=0d0c8278-ef8e-4d6c-ab21-f5527e322f13)) <!-- /greptile_comment -->
