The author ran the Aider benchmark with Qwen 3.8 27B FP8 + FP8 KV cache at 256K context on vLLM. Score: 72.9 — matching Gemini 2.5 Pro (2025-04-12, 72.9), beating Claude Opus 4 (2025-05-25, 72.0) and DeepSeek R1 (71.4).

He notes it's an older benchmark, but it's remarkable that a MacBook now matches SOTA models from just over a year ago. Real-world performance is even better since the harness improved: with the DeepSeek Harness it would solve most if not all Aider tests, though often using more than 2 turns.
