Models & Providers
Frontman offers a curated catalog of models for text, coding, and tool use. A catalog entry does not guarantee access through your account. Provider plans, workspace rules, and rollouts can restrict access.
This reference was reviewed on September 29, 2026. The provider configuration defines the picker options and validates execution requests. See API Keys & Providers for connection instructions.
OpenAI
Section titled “OpenAI”Connection: ChatGPT OAuth through Codex, not an OpenAI API key.
| Model | ID |
|---|---|
| GPT-6 Astra | gpt-6-astra |

Selection and availability
Section titled “Selection and availability”Frontman preserves a saved selection while it remains in the catalog. Otherwise, it selects the first available option. A newly connected provider selects its first model. Use the dropdown in the chat header to change models.
Google and xAI have no direct picker entries. Use their listed models through OpenRouter. An upstream model in LLMDB is not automatically a Frontman option. ReqLLM must also support its request format, authentication, and tool streaming.
If a provider rejects a model, select an available replacement and send a new message. Retrying a failed turn keeps its original model. Frontman does not silently move your request to another provider.
