Qwopus3.5‑v3: From Reason‑Then‑Act to Act‑Then‑Refine – Claude‑Opus Distillation Turns Qwen3.5 into a Tool‑Using Agent

The newly released Qwopus3.5‑v3 model combines higher‑quality reasoning chains, dedicated tool‑calling reinforcement learning, and an act‑then‑refine paradigm, delivering a 5‑point HumanEval boost, a 1.43‑point MMLU‑Pro gain, 31.7% faster inference and 24% lower token cost, while remaining runnable on a 3090 or a 16 GB MacBook, with easy deployment via GGUF, LM Studio, Ollama or llama.cpp.
