Недавно делал быстрый прототип асинхронного приложения в котором требовалось вызывать много синхронного кода. Да, я знаю, что это не лучший дизайн, но нужно было быстрое решение на один процесс и без очередей. Поэтому я выполнял код в потоках. Выглядело это примерно так: from fastapi.concurrency import run_in_threadpool async def execute(data: DataRequest) -> DataResponse: try: result = await run_in_threadpool(sync_function, data) return DataResponse(data=result) except Exception as e: return DataResponse( error=str(e), success=False, ) В общем работает нормально. Для всех вызовов под капотом используется общий тредпул, всё работает предсказуемо. Но потребовалось изменить количество запускаемых в пуле потоков (по умолчанию создается 40 воркеров). Так как дело происходит с FastAPI, делается это через lifespan используя настройки anyio: import anyio @asynccontextmanager async def lifespan(app: FastAPI): limiter = anyio.to_thread.current_default_thread_limiter() limiter.total_tokens = 100 yield # если вдруг нужно вернуть обратно limiter.total_tokens = 40 Зачем менять количество воркеров? - уменьшить, если оперативки мало (один тред занимает ~8мб) - увеличить чтобы выдержать нагрузку Если есть предложения получше при тех же вводных - предлагайте😉 #async

OpenAI has launched GPT-4o, and it’s a game-changer for AI interaction! With GPT-4o, ChatGPT now delivers ultra-fast, natural voice conversations that feel incredibly human. It’s not just about talking, though—the model can actually see and interpret what’s happening around it in real time. Now it can respond to visual inputs and adjust its tone and expressions based on emotional cues, making conversations smoother and more engaging. The model will be available to all users for free soon. @Viral_Today / #technologies

All behaviors are learned (not teleoperated) and run at normal speed (1.0x). The images from the robot's cameras and transcribed text from speech captured by onboard microphones are fed to a large multimodal model trained by OpenAI that understands both images and text. The model processes the entire history of the conversation, including past images, to come up with language responses, which are spoken back to the human via text-to-speech. The same model is responsible for deciding which learned, closed-loop behavior to run on the robot to fulfill a given command, loading particular neural network weights onto the GPU and executing a policy. @Viral_Today / #technologies
