Model Overview

The vvsotnikov/Qwen3.8-27B-0.9-Qwen3.6-27B-0.1 is a 27 billion parameter language model, resulting from a direct linear interpolation of two upstream Qwen checkpoints: Qwen/Qwen3.6-27B and Qwen/Qwen3.8-27B. Specifically, the merged model is calculated as 0.1 * Qwen/Qwen3.6-27B + 0.9 * Qwen/Qwen3.8-27B.

Merge Details

  • Methodology: The interpolation was performed element-wise in float32, with results cast back to bfloat16. This process involved merging 1,199 tensors, including embedded mtp.* drafter tensors and the vision tower.
  • Configuration: The shard layout, configuration, tokenizer, processor, and chat template are inherited from Qwen/Qwen3.8-27B, which has the larger merge coefficient.
  • Source Revisions: The specific revisions used for the base models were 6a9e13bd6fc8f0983b9b99948120bc37f49c13e9 for Qwen/Qwen3.6-27B and 1d4bf0f2ff6012fd82039f2fa52739d0dd7c60c0 for Qwen/Qwen3.8-27B.
  • Quantization: No quantization was applied during the merge process.

Licensing and Usage

Both source checkpoints, Qwen/Qwen3.6-27B and Qwen/Qwen3.8-27B, are released under the Apache-2.0 license. Users should refer to the upstream model cards for detailed information regarding capabilities, limitations, and expected qwen3_5 runtime support.
