Google Cloud reproduced the Allen Institute for AI's Olmo 3 7B model using MaxText on TPUs, matching the original training loss curve and held-out metrics. The team converted the PyTorch architecture to JAX, implementing a reordered-norm block, QK-norm, and 3:1 sliding/global attention while catching a data-loader bug that caused memorization. The run tracked the full ~5.93T-token / 1.41M-step budget, sustaining 57.4% MFU on v5p devices during stage 2.written, reviewed, cited
- The team lost three quarters of capacity mid-run but resumed on a quarter-sized slice with no recipe change.

AllenAI released Olmo 3.1 Think 32B and Olmo 3.1 Instruct 32B, the most performant checkpoints to date. The Think variant extended the best reinforcement learning run with an additional 21 days on 224 GPUs, yielding improvements of 5+ points on AIME, 4+ points on ZebraLogic, 4+ points on IFEval, and 20+ points on IFBench. The Instruct variant applies the recipe behind Olmo 3 Instruct 7B to a larger model for chat and tool use.written, reviewed, cited
- Olmo 3-Think (32B) narrows the gap to top open models while training on roughly 6x fewer tokens than competitors.
- The model flow allows users to swap in domain-specific data during mid-training or adjust post-training for specific use cases.
- Olmo 3-Base (32B) achieves competitive performance with Qwen 2.5 and Gemma 3 while maintaining full openness of weights and code.

NCP-ArchPreview is a latent-space language model that pushes autoregressive pretraining beyond standard next-token prediction by learning to predict discrete concepts spanning multiple tokens. The 8.9B parameter model trains on 5.73T tokens from the Dolma-3 dataset, consuming only 51.3% of total training tokens to match OLMo-3-7B's loss while outperforming it by 2.45 points on the downstream macro-average and 5.99 points on GSM8K. Updating just the 17M-parameter VQ module yields a novel, lightweight interface for domain adaptation.written, reviewed, cited

Olmo 3 is a fully open LLM series from Ai2 that releases training data, processes, and checkpoints alongside model weights. The 32B-scale model is pretrained on a ~9.3-trillion-token corpus and trains on roughly 6x fewer tokens than competing models. During testing, the 32B Think model took 14 minutes 43 seconds to generate 8,437 tokens for a simple SVG request.written, reviewed, cited
- The 7B Instruct model download size is 4.16GB.
- OlmoTrace currently relies on phrase matching to find training documents.

Olmo 3 introduces a new family of fully open language models available today, featuring 7B and 32B variants. This family represents the first 32B (or larger) fully open reasoning model and the best 7B Western-origin thinking and instruct models. The 32B Thinker scores get within 1-2 points overall with their respective Qwen3 8/32B models.written, reviewed, cited
- Olmo 3 Instruct models represent the best 7B scale model from a Western or American company.
- The 32B range is largely devoid of non-Qwen competition for reasoning models.
