Qwopus3.5-9B-Coder-GGUF Puts A Private Coding Agent On Your Laptop

A minimalist matte white laptop features a flowing ribbon of translucent code strands of indigo and pale lavender.

Qwopus3.5-9B-Coder-GGUF is a compressed, ready-to-run model file that brings an experimental 9‑billion‑parameter coding agent to local machines. It specializes in writing, debugging, and refactoring code, and can call tools like terminals and browsers. You can run it on a standard laptop with 16 GB of RAM and an 8‑bit quantized version.

Jackrong, who also brought us Qwopus3.6-27B-v1-preview-GGUF fine‑tuned the base Qwopus3.5‑9B‑v3.5 model using a pipeline that blends Trace Inversion data augmentation with real agent reasoning traces. The process reconstructs the hidden logical steps behind commercial‑model answers and teaches the model more structured thinking and stable tool use. The result is a community experiment that focuses purely on research and exploration, not a polished general assistant.

Optimized for agentic coding and logical reasoning

Key Features
  • Lightweight 9B model runs on 16GB laptops.
  • Vision support with included mmproj.gguf file.
  • Reliable tool calling for terminal, files, browser.
  • Structured reasoning wrapped in <think> tags.
  • 32K context training, extendable with RoPE scaling.
  • High scores on HermesAgent‑20 and ToolCall‑15.
  • Trained with real agent traces, not synthetic data.
  • Experimental community release, research use only.

The model fits developers and tinkerers who want a private, offline coding assistant that lives on a single GPU or laptop. Privacy‑conscious professionals can use it to debug code, generate scripts, or automate workflows without sending data to the cloud. Hobbyists and small teams can explore agentic pipelines, as long as they accept its experimental nature and reduced strength on tasks outside programming.

What to know before downloading

The developer cautions that vertical fine‑tuning for coding and reasoning can cause “capability decay” on general language tasks. Tool calling only works correctly when you apply the specific prompt format used during training, and the reasoning inside <think> tags may need to be hidden in some front‑end setups. For context lengths beyond 32K, you should enable YaRN scaling—simply raising the context window can make behavior unstable.
