qwopus3.6-35b-a3b-coder-mxfp8-mlx

MLX MXFP8 MLX conversion of Jackrong/Qwopus3.6-35B-A3B-Coder, prepared by Shiftedx for Apple Silicon / MLX / LM Studio.

What Changed

• Converted from the upstream safetensors checkpoint with the local streaming MLX pipeline.
• Quantized primary linear weights with mxfp8 at group size 32.
• Kept MoE router/gate modules in affine 8-bit group size 64 for compatibility.
• Removed source MTP tensors and set MTP/next-token prediction layer counts to 0 for LM Studio compatibility.
• Set tool_parser_type to qwen3_coder.
• Patched the chat template so enable_thinking defaults to false when a runtime honors the template variable.
• Removed vision tensors/config for a smaller language-only build.

Local Validation

Hardware reference: Apple M4 Max Apple Silicon with 64 GB unified memory.

Validated locally on June 29, 2026 with LM Studio server on port 8080, 32k context, parallel 1, GPU max.

Note: LM Studio may still report hidden reasoning_tokens for this checkpoint even though the upstream model is intended for thinking-off use. Use adequate max_tokens for smoke tests.

LM Studio

After downloading in LM Studio, load the model key:

lms load qwopus3.6-35b-a3b-coder-mxfp8-mlx --context-length 32768 --parallel 1 --gpu max

Recommended profile defaults, matching the local Shiftedx 35B AgentWorld/Ornith profiles:

• Preset/template: Qwen3 thinking-compatible Jinja template with <|im_end|> stop.
• Context length: 200000 when memory allows; 32768 was used for local smoke validation.
• Sampling: temperature 0.6, top-k 20, top-p 0.95, min-p enabled at 0.
• Repeat penalty: unchecked/off, value 1.1 if enabled manually.
• Load: parallel 1, GPU max.
