Ai2's OLMo 3.1: truly open-source models with enhanced reasoning and instruction-following capabilities

Olmo 3: Train Your Own AI Model for Less

Subscribe The Allen Institute for AI recently released its most powerful model ever: Olmo 3. Olmo is cheap to train, making it perfect for anyone training their own model.  Olmo 3 is 2.5 times more efficient to train than Llama 3.1 based on GPU-hours per token. Olmo is also much more transparent than other models. Most so-called “open source” models, like Llama or DeepSeek, are really just “open weight.” They give you the weights, but they won’t…

Ai2's OLMo 3.1: truly open-source models with enhanced reasoning and instruction-following capabilities

The Allen Institute for AI (Ai2) has released OLMo 3.1, an updated version of its fully open-source language model family featuring significantly improved reasoning and instruction-following capabilities. Coming less than a month after the November launch of OLMo 3, the release includes two new 32B parameter checkpoints that represent the organization's most performant models to date.OLMo 3.1 Think 32B extends the original reinforcement learning…
