Использование Pydantic сегодня стало нормой, и это правильно. Но иногда на ревью вижу, что используют его не всегда корректно. Например, метод BaseModel.model_dump() по умолчанию не преобразует стандартные типы, такие как datetime, UUID или Decimal, в простой сериализуемый для JSON вид. Тогда пишут кастмоный сериализатор для этих типов чтобы функция json.dump() не падала с ошибкой. import uuid from datetime import datetime from decimal import Decimal from uuid import UUID from pydantic import BaseModel class MyModel(BaseModel): id: UUID date: datetime value: Decimal obj = MyModel( id=uuid.uuid4(), date=datetime.now(), value='1.23' ) print(obj.model_dump()) # не подходит для json.dump # { # 'id': UUID('4f8c1bc4-25fd-40cd-9dbe-2c73639b0dc1'), # 'date': datetime.datetime(2025, 12, 12, 12, 12, 12, 111111), # 'value': Decimal('1.23') # } # добавляем свой кастомный сериализатор json.dumps(obj.model_dump(), cls=MySerializer) # { # 'id': '4f8c1bc4-25fd-40cd-9dbe-2c73639b0dc1', # 'date': '2025-12-12T12:12:12.111111', # 'value': '1.23' # } В данном случае класс MySerializer обрабатывает datetime, UUID и Decimal. Например так: class MySerializer(json.JSONEncoder): def default(self, o): if isinstance(o, Decimal): return str(o) elif isinstance(o, datetime): return o.isoformat() elif isinstance(o, UUID): return str(o) return super().default(o) Специально для тех, кто всё еще так делает - в этом нет необходимости! Pydantic может это сделать сам, просто нужно добавить параметр mode="json". json.dumps(obj.model_dump(mode="json")) # { # 'id': '4f8c1bc4-25fd-40cd-9dbe-2c73639b0dc1', # 'date': '2012-12-12T12:12:12.111111', # 'value': '1.23' # } #pydantic#libs

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
