Meet Ai2 Paper Finder, an LLM-powered literature search system.

Searching for relevant work is a multi-step process that requires iteration. Paper Finder mimics this workflow — and helps researchers find more papers than ever 🔍 Paper Finder breaks down your query into relevant components, such as searching for papers, following citations, evaluating for relevance, and running follow-up queries based on the results. It then presents not only the papers, but also short summaries of why the paper is relevant to your specific query.

Here is Tülu 3 405B 🐫 our open-source post-training model that surpasses the performance of DeepSeek-V3! The last member of the Tülu 3 family demonstrates that our recipe, which includes Reinforcement Learning from Verifiable Rewards (RVLR) scales to 405B - with performance on par with GPT-4o, and surpassing prior open-weight post-trained models of the same size including Llama 3.1 Benchmarking Tülu 3. Interesting finding: Reinforcement Learning from Verifiable Rewards (RLVR) framework improved the MATH performance more significantly at a larger scale, i.e. 405B compared to 70B and 8B, similar to the findings in the DeepSeek-R1 report.

Meet Tülu 3 -- a set of state-of-the-art instruct models with fully open data, eval code, and training algorithms.

We invented new methods for fine-tuning language models with RL and built upon best practices in the community to scale synthetic instruction and preference data.

OLMo is here! And it’s 100% open.

It’s a state-of-the-art LLM and we are releasing it with all pre-training data and code. Let’s get to work on understanding the science behind LLMs. Learn more about the framework and how to access it here:

Huge shout out to all our partners including @databricks, @AMD, @LUMIhpc and @KempnerInst for their support in making the OLMo framework possible. We are excited to build a future together where AI is truly open.

How large an emergency fund do I need? Do I have enough time to grab lunch before my next meeting?
We intuitively solve questions like these every day. Renowned physicist Enrico Fermi had a particular knack for it — these questions have become well known as Fermi Problems.
1/N Solving Fermi Problems requires recursive decomposition, science/commonsense reasoning, abstraction, and creativity. The inherent complexity of these problems makes them an ideal candidate for #AI reasoning.
