The algorithm behind DeepSeek's R1 model (aka GRPO) now lives in TRL main branch! Go and test it!

[Stonks] TRL is a Python library for training language models.

It has seen impressive growth this year. Lots of new features, an improved codebase, and this has translated into increased usage. You can count on us to do even more in 2025.

🚨 TRL 0.13 is out! 🤗

Featuring a Process-supervised Reward Models (PRM) Trainer 🏋️

PRMs empower LLMs to "think before answering"—a key feature behind OpenAI's o1 launch just two weeks ago. 🚀

We outperform Llama 70B with Llama 3B on hard math by scaling test-time compute 🔥

How? By combining step-wise reward models with tree search algorithms :)

We're open sourcing the full recipe and sharing a detailed blog post 👇

The number of TRL models on the 🤗 Hub has risen x60 this year! 📈
How about doing the same next year?

We took those TRL notebooks from last week and made a page from them. So if you're upskilling on finetuning or aligning LLMs, and want examples from the community (like Maxime Labonne Philipp Schmid Sergio Paniego Blanco), check it out!

These tutorials provide a comprehensive but concise roadmap through TRL across the main fine-tuning and alignment classes.

🤔 Let me know if you would like a dedicated course on TRL basics.

It's Sunday morning so taking a minute for a nerdy thread (on math, tokenizers and LLMs) of the work of our intern Garreth

By adding a few lines of code to the base Llama 3 tokenizer, he got a free boost in arithmetic performance 😮

How can you avoid the temptation to use a subprocess for sub-commands?
