Ai2 @ai2.bsky.social · 18/08/2025We didn’t initially enable frequent early checkpointing for OLMo-2-1B. But to support researchers and the broader AI community, we’re generating checkpoints post-hoc. 🎯 130
Ai2 @ai2.bsky.social · 18/08/2025📎 Note: these checkpoints use the same OLMo-2-1B architecture and starting checkpoint, but they aren’t identical to the originals due to the non-deterministic nature of LLMs. Performance may differ slightly. 130
