Lumix-35B

Lumix-35B is a vision-capable coding and reasoning model from Blackfrost, distributed as GGUF quantizations for llama.cpp and Ollama. It is a fine-tune of Qwen3.6-35B-A3B (Mixture-of-Experts), tuned to drive the Shadow coding agent.

  • Base: Qwen/Qwen3.6-35B-A3B-FP8 (GGUF architecture qwen35moe)
  • Parameters: ~35B total (Mixture-of-Experts, a few B active per token)
  • Modalities: text + vision (image input via the bundled mmproj)
  • Context: long-context, agentic coding — one clean tool call at a time, look → act → verify
