GPUburnout-3B-75K-Chat (RETIRED)

This model is retired. It was trained in April 2026 with a buggy SFT data formatter (plain string concatenation instead of apply_chat_template), which caused loop collapse at inference and made it underperform the smaller 2B chat model on most benchmarks.

Use GPUburnout/GPUburnout-3B-75K-Chat-v2 instead.
