# Qwen3.5 9B - Opus Agent
This is a finetune on Opus traces and a small dataset. Reasoning was left untouched
Total train time: 4 hours
## Benchmarks
### General benchmarks
Benchmarks provided by [@nightmedia](https://huggingface.co/nightmedia), as always thanks for taking the time :)
```
arc arc/e boolq
armand0e/Qwen3.5-9B-Opus-Agent 0.589 0.747 0.901
Jackrong/Qwopus3.5-9B-Coder 0.561 0.721 0.89
Qwen3.5-9B 0.571 0.719 0.895
```
### Targeted benchmarks
Conducted via [BenchLocal](https://github.com/stevibe/BenchLocal). All benchmarks are 2-shot (1 retry on failure) for ease of comparison to the numbers found in [Jackrong's Qwopus3.5 Coder](https://huggingface.co/Jackrong/Qwopus3.5-9B-Coder-GGUF)
All benchmarks for other models were done in Q8_0 only this model's benchmarks were done in Q4_K_M
1. Instruction Following - InstructFollow-15
InstructFollow-15 evaluates formatting, count, numbering, sentence, and length constraints.
2. Code Debugging & Bug Fixing - BugFind-15
BugFind-15 evaluates real debugging capability across syntax bugs, logic errors, and trap code.
3. Tool Call Stability - ToolCall-15
ToolCall-15 targets stability and precision in direct tool-calling behavior.
4. Complex Agent Performance - HermesAgent-20
HermesAgent-20 evaluates complex agent behavior across memory, orchestration, skill use, scheduling, and delegation.
