Connecting your LLM provider
Tell Nairi which model and provider your agents should use — Claude, Codex, or OpenCode.
Every agent runs through a coding-agent CLI (Claude Code, Codex, or OpenCode) backed by a model from a provider you choose. Add the provider once, then point each agent at the model you want.
Adding your own provider
All provider setup lives at Settings → Integrations → LLM Integrations → Add integration. Each provider has its own setup tab.
Anthropic (Claude Code)
Paste an sk-ant-... API key. Anthropic bills you directly for model usage. Useful for cost reporting, higher rate limits, or accounting separation.
Models available: Claude Opus 4.7, Claude Sonnet 4.6, Claude Haiku 4.5.
Codex (OpenAI)
Paste an OpenAI API key. OpenAI bills you per token.
Models available: GPT 5.5, GPT 5.4, GPT 5.4 Mini, GPT 5.3 Codex, GPT 5.2.
OpenCode
OpenCode is a multi-provider gateway that exposes one API for many models. Paste an Opencode Zen API key to connect.
Models available: Claude (Opus, Sonnet, Haiku), GPT (5.5, 5.5 Pro, 5.4, 5.4 Mini, 5.3 Codex), Gemini 3.1 Pro, Gemini 3 Flash, GLM, Qwen, Kimi, MiniMax, and more (30+ at last count).
Choosing per agent
Each agent picks one provider and one model at a time, set on the agent editor. See Choosing a model for which to pick for which kind of work.
You can change an agent's provider or model any time. The change takes effect on the next task; in-flight tasks finish on whatever they started with.
