Pydantic V2 Is Here!


The last few months have involved a whirlwind of work, and we're finally ready to announce to official release of Pydantic V2!

Getting started with Pydantic V2

To get started with Pydantic V2, install it from PyPI:

pip install -U pydantic

Pydantic V2 is compatible with Python 3.8 and above.

See the docs for examples of Pydantic at work.

Help Us Build Our Roadmap | Pydantic


Back in February I announced Pydantic Inc., but I didn't explain what services we were building.

Today I want to provide a little more detail about what we're planning to build, and get your feedback on the components via a short survey.

In return for giving us your honest feedback, you have the option to be added to our early access list, to get invited to the closed beta of our platform once it's ready to use.

Pydantic V2 Pre Release


We're excited to announce the first alpha release of Pydantic V2!

This first Pydantic V2 alpha is no April Fool's joke — for a start we missed our April 1st target date 😢. After a year's work, we invite you to explore the improvements we've made and give us your feedback. We look forward to hearing your thoughts and working together to improve the library.

For many of you, Pydantic is already a key part of your Python toolkit and needs no introduction — we hope you'll find the improvements and additions in Pydantic V2 useful.

If you're new to Pydantic: Pydantic is an open-source Python library that provides powerful data parsing and validation — including type coercion and useful error messages when typing issues arise — and settings management capabilities. See the docs for examples of Pydantic at work.

Company Announcement | Pydantic


Update: If you find this article interesting, you might also like the TechCrunch article and Sequoia blog post about Pydantic.


I've decided to start a company based on the principles that I believe have led to Pydantic's success.

I have closed a seed investment round led by Sequoia, with participation from Partech, Irregular Expressions and some amazing angel investors including Bryan Helmig (co-founder and CTO of Zapier), Tristan Handy (founder and CEO of Dbt Labs) and David Cramer (co-founder and CTO of Sentry).
