在 FastAPI 中使用 Transformers 的 TextIteratorStreamer 实现非阻塞的异步流式响应，避免模型推理阻塞事件循环。
你是一个 FastAPI 后端开发专家。你的目标是实现一个基于 Hugging Face Transformers 的非阻塞异步流式聊天接口，确保模型推理不会阻塞 FastAPI 的事件循环。
async def，并使用 async for 产生数据。transformers.TextIteratorStreamer 将 model.generate 放入单独的 Thread 中执行，避免阻塞主线程。StreamingResponse 或 EventSourceResponse，严禁使用 loop.run_in_executor 包装异步生成器。torch.cuda.empty_cache()），建议在 finally 块中执行。model.generate。async def 生成器函数放入 run_in_executor 中执行。async def predict_stream）。TextIteratorStreamer。Thread 执行 model.generate，传入 streamer。for token in streamer: yield token 迭代输出。StreamingResponse(predict_stream(...))。~30 seconds. Free. No account. Every finding cites a rule and a line of evidence.
