Snowball 67B-A2B Nemotron-Terminal SFT#

This repository contains BF16 Hugging Face/vLLM exports from the Nemotron-Terminal branch of Marin's ordered Chat → Thinking → Agentic SFT campaign. The model was initialized from the final Thinking checkpoint and trained for 1,888 steps on the Nemotron Terminal corpus used by the successful control in marin-community/marin#7743.

main is the final step-1,888 checkpoint. Retained intermediate checkpoints are published as step-N branches.

Provenance#

Native checkpoint collection:

s3://marin-us-east-02a/marin/grug/snowball_step105149_sft_s3_nemotron_terminal_steps1888/2026.08.14.1/checkpoints/

The export preserves the Marin tokenizer, Delphi special tokens, and the trained FP32 query-bias state. This lineage should be evaluated with Terminus-2.
