Qwen3.5-DeltaCoder-9B-GGUF
v1.1-DPO — Now with DPO alignment for improved code correctness and self-verification. If you downloaded before March 28, 2026, please re-pull to get v1.1-DPO.
GGUF quantizations of Qwen3.5-DeltaCoder-9B for use with llama.cpp, Ollama, LM Studio, and other GGUF-compatible inference engines.
What's New in v1.1-DPO
- DPO alignment on 4,519 preference pairs from AceCode-V2-122K
- Self-correcting behavior — model now detects and fixes its own bugs rather than submitting incorrect code
- Improved code correctness — trained to prefer passing solutions over failing ones
- Same tool-call reliability as v1 — SFT improvements preserved through two-stage merge

Recommended Sampling Settings
| Parameter | Value |
|---|---|
| temperature | 0.6 |
| top_k | 20 |
| top_p | 0.95 |
| min_p | 0.0 |
| presence_penalty | 0.0 |
| repeat_penalty | 1.0 |
[!WARNING] Do not use temperature below 0.5 — low temperatures cause deterministic looping in multi-turn agentic use.

Benchmarks
| Model | HumanEval | HumanEval+ | Terminal-Bench Easy |
|---|---|---|---|
| Jackrong Qwen3.5-9B-v2 (base) | 53.7% | — | — |
| DeltaCoder-9B v1 (temp=0.6) | 50.6% | 49.4% | 2/4 (50%) |
