OLMo 3 7B — ClimbMix only

Annealing-only run from the pretrained Stage 1 weights. The HF optimizer is not imported; a fresh optimizer and scheduler are used.

Base model

allenai/Olmo-3-1025-7B at revision stage1-step1413814. These checkpoints are base models, not instruction-tuned or chat-tuned models.

Training data

  • annealing data: ClimbMix only — Exactly 12B tokens: 100% ClimbMix.

Training configuration

| Context length | 8,192 tokens | | Global batch | 256 sequences | | Micro batch | 2 sequences per rank | | Steps / target | 5,723 steps / 12,002,000,896 processed tokens | | Optimizer | Distributed Adam, weight decay 0.1 | | Learning rate | 1e-5 peak; linear warmup and linear decay to zero | | Precision | BF16 | | GPUs | 8, data parallelism 8 | | Seed | 42 | | Evaluation during training | Disabled |

The repository contains checkpoint revisions named step-XXXXXXX; main is the final checkpoint. Optimizer states are not part of these HF exports. The exact source paths, revision mapping, and publication code are maintained in the private KletterMix_Ablations repository.
