2026.08.07: littlerock-1M and littlerock-1M-arithmax
A 1,002,720-parameter Llama-architecture model trained from scratch on 5B tokens (40% FineWeb-Edu, 60% DCLM-baseline) in 1 hour 49 minutes, published with an arithmetic-finetuned sibling that serves as a worked example of benchmark specialization surviving a rigorous contamination audit. Full analysis on the littlerock page.
2026.08.01: Boris-1.3-125M-Instruct and GGUF builds
Instruction-tuned on smol-smoltalk and OASST1 over 5.6 hours, with quantized GGUF builds for llama.cpp published the same day.
2026.07.31: Boris-1.3-125M
Seven continued-pretraining passes on the Boris-125M base checkpoint, adding ~2.66B tokens — about 106% more than the original 2.50B-token pretraining run — and raising Mean-6 from 37.88 to 39.38. Leading with FineWeb-Edu before DCLM avoided the ARC regression seen at 75M.
2026.07.26: Boris-1.3-75M and Instruct
Three continued-pretraining passes bring the 75M model to ~3.95B total training tokens and a Mean-6 of 36.79, with instruct and GGUF variants alongside.
2026.07.23: Boris-250M, and GGUF builds across the board
The largest Boris to date, in base and instruct form, plus quantized GGUF builds for the 75M, 125M, and 250M instruct models.
2026.07.18: Boris-75M and Boris-75M-Instruct
A 77.4M-parameter sibling to the original release.
2026.07.15: NMAI becomes OpenCerebral; first release
New Millennium Artificial Intelligence, a division of the Klondike Software Project, is renamed OpenCerebral. The organization, models, and maintainers are unchanged. The same day, Boris-125M and Boris-125M-Instruct are published as the project's first public models.
