Research artifact. This model has not been properly tested or evaluated and is not necessarily secure. Use at your own risk in production settings. This is the dare-ties-02 checkpoint from the second Snowball/Grug model-merging campaign. It transfers specialist updates into the Base checkpoint while preserving 93.96% of Base scalar weights bit-for-bit. The measured changed fraction is 6.037362616948686%, within the campaign's 25% cap. NUPA scored all 200 tasks; BFCL scored all 123 trials. The NUPA zero received the required ten-trace review. These are development benchmark results, not held-out evidence. Non-target capability retention was not evaluated for this checkpoint. The merge applies DARE-TIES within the fixed R25 routed-expert support (1,705 expert blocks). DARE keep density is 0.20, TIES trimming density is 0.20, the NUPA/BFCL delta coefficients are 0.50/0.50, the scale is 1.00, and the random seed is 0. Outside the selected support, weights are copied from Base unchanged. Tokenizer, chat template, model…

Parameter count is not a RAM/VRAM requirement. Check precision, quantization, context length and runtime compatibility in the model card; no hardware or API-cost claim is inferred here.
Use and evaluate
Check license terms and access requirements first. Review the model card’s documented loading instructions, evaluations and safety limitations. Benchmark scores are not imported by this directory, and popularity is not an accuracy ranking.
No model weights are downloaded or executed by AltAPIs. Never enable remote model code without reviewing it.
