Drop-in replacement for OpenAI’s POST /v1/chat/completions. Point any OpenAI SDK at base_url=https:///oai/v1 and use a Quant API token (qc_…) as the api_key. Set stream: true to receive Server-Sent Events (chat.completion.chunk objects terminated by data: [DONE]); otherwise a single chat.completion object is returned. Supports tool/function calling and the standard tool_choice modes.
