Connecting your LLM provider
Tell Nairi which model and provider your agents should use — Claude, Codex, or OpenCode — and supply the API key. Switch providers per agent.
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.

Connecting GitHub
Install the Nairi GitHub App so agents can read your repos, push feature branches, and open pull requests. Scope access per repository or to the whole org.
How to deploy an agent
