GPT-3.5 Turbo 16k 是否为 OpenAI 官方发布的模型？
资料中称其为‘纯官方高速GPT3.5 16K系列’，但未提供OpenAI官方发布页面或版本号佐证；第三方API平台（如Apilio、OpenRouter）将其列为可用模型。
该模型是否支持结构化输出（如JSON Schema）？
资料明确标注标签 'structured_outputs'，结合 'function_call' 支持，表明具备结构化响应能力，但具体实现方式（如是否原生支持JSON mode）未说明。
它与标准 GPT-3.5 Turbo（4k）的主要区别是什么？
主要区别在于上下文长度：本模型支持16,385 token，显著高于标准版约4,096 token，更适合长文本交互场景。
Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
