We just updated the OLMo repo at github.com/allenai/OLMo!
There are now several training configs that together reproduce the training runs that lead to the final OLMo 2 models.
In particular, all the training data is available, tokenized and shuffled exactly as we trained on it!

olmocr est un outil permettant de linéariser les documents PDF en vue de leur exploitation par des LLM à des fins d’entraînement ou de création de datasets. Très pratique pour extraire de la donnée relativement structurée et exploitable ⬇️

🔥 allenai/Llama-3.1-Tulu-3-8B (trained with PPO) -> allenai/Llama-3.1-Tulu-3.1-8B (trained with GRPO)

We are happy to "quietly" release our latest GRPO-trained Tulu 3.1 model, which is considerably better in MATH and GSM8K!

Reading the TÜLU 3 paper from @ai2.bsky.social. It's refreshing to see a research lab treating AI as a real science with full reports, data, code, logs, evals.

Paper: allenai.org/papers/tulu-...
Demo: playground.allenai.org
Code: github.com/allenai/open...
Eval: github.com/allenai/olmes

These leaks are getting crazy. First the Claude Code source code leaks, and now apparently someone from AI2 leaked the olmo training code on github?

My response to ASU + OpenAI is that universities cannot afford to outsource aspects of *thinking*. We should partner instead with AllenAI & HuggingFace &c and help build public open-source models to support instruction.

AllenAI just made trillion-parameter MoE training 2.7x faster with a clean architectural shift: keep experts GPU-resident, route data to them. Open source and benchmarked at 1.2T params on 512 B300 GPUs. https://huggingface.co/blog/allenai/olmocore3

Inspiring work! Btw your emo collection doesn’t exist on huggingface so the links to the models are broken (here and in your blog post).

For anyone else reading, this is the link for what appears to be the main model: huggingface.co/allenai/Emo_...

So happy OLMo 2 is out! We applied the same Tülu 3 RLVR recipe and it worked very nicely for our final 13B instruct model.
Here are the gains/losses of allenai/OLMo-2-1124-13B-Instruct (RLVR's checkpoint) over allenai/OLMo-2-1124-13B-DPO. More to share soon!

Against the constant pressure of *genAI, genAI, genAI*, I am really appreciating @ai2.bsky.social 's work on creating tools for critical needs -- like crop maps and forest loss analysis. They just did a nice release on @hf.co.

Need AllenAI or someone like that to train a very small model for just this purpose
making world's most overengineered thermostat by explaining my air quality preferences to a local LLM and tasking it with regularly monitoring all the sensors and figuring out how to get the room as close as possible to the desired state

I'm really happy with Tulu 3 8B. Is nice in the hosted demo (playground allenai org), but also quantized running locally on my mac in LM studio D. Feels like a keeper.

What's with these arguments over whether X or Y or whatever was the first LLM RL library? These all came in the last 3 months

We wrote multiturn RL4LMs like 3+ years ago github.com/allenai/RL4LMs

There were other simple versions even before. ML ppl approaching goldfish memory

Olmo 3 32B Think is now free on Open Router until 12/22.
Let us know what you think and what to improve!

This may give it the hug of death... would be my dream.
