.chat_raw(opts = {}) ⇒ Object

Supported Method Parameters

response = PWN::AI::OpenAI.chat_raw(

messages: 'required - full OpenAI-format messages array (system/user/assistant/tool)',
tools: 'optional - OpenAI tools array [{type:"function", function:{...}}]',
tool_choice: 'optional - "auto" | "none" | "required" | {type:"function", function:{name:..}}',
model: 'optional - overrides PWN::Env[:ai][:openai][:model]',
temp: 'optional - temperature (defaults to PWN::Env[:ai][:openai][:temp] || 1)',
timeout: 'optional - seconds (default 180)',
spinner: 'optional - display spinner (default false)'

)

Returns the raw chat/completions response Hash with :choices intact (including :message) — used by PWN::AI::Agent::Loop. Unlike .chat, this does NOT flatten the assistant message into response_history; the caller owns the messages array.
