Overview

OpenAI-compatible backend (GPT, Groq, DeepSeek, Ollama, etc.)

Translates between Mana's internal format (Anthropic-style) and OpenAI's:

- system prompt: top-level `system` → system message
- tool calls: `tool_use`/`tool_result` blocks → `tool_calls` + `role: "tool"`
- response: `choices` → content blocks

Instance Method Details

#chat(system:, messages:, tools:, model:, max_tokens: 4096) ⇒ Object

Translates to OpenAI format, posts, then normalizes back to Anthropic format. Uses max_completion_tokens (not max_tokens) per OpenAI's newer API convention.
