Is 0.001 slow for you? Do your users notice such a small difference in time? Database and Telegram Bot API latency matters, not serialization time, pay attention to your database and network. You are measuring class initialization + simple validation this is not even a pydantic problem (mostly), it's just how Python works. Change pydantic to dataclasses with manual deserialization - you will see the same or worse result. Conversely, without using serialization models (their removal) significantly increases complexity and reduces usability for framework users (bot developers).
