Agent runtimes
Connect an agent
Enable an agent runtime and connect the provider account it will use. Kern handles the host setup.
Supported runtimes
| Runtime | Provider connection | Supported models |
|---|---|---|
| Codex | OpenAI | gpt-5.6-terra, gpt-5.6-sol, gpt-5.6-luna |
| Claude Code | Anthropic | claude-opus-5, claude-fable-5, claude-sonnet-5 |
| Grok | xAI | grok-4.6 |
| Hermes | Amazon Bedrock | deepseek.v3.2, qwen.qwen3-coder-next, moonshotai.kimi-k2.5 |
Each thread picks one runtime and model, plus a reasoning effort the runtime supports. Kern names exact model versions rather than moving aliases, so an existing thread never changes model generation underneath you.
