**Source:** [`atloria-monorepo/libs/agent-core/src/runtime/model-profiles.ts`](https://github.com/sherkety/atloria/blob/main/atloria-monorepo/libs/agent-core/src/runtime/model-profiles.ts#L125)

GPT-5.4 (Azure Responses API) — the Atloria primary model.
Key quirks:
  - reasoning_effort defaults to 'none' → skips tool calls
  - temperature is unsupported when reasoning is active
  - tool_choice: 'required' needed on turn 1 to force at least one call
