Qwen3.8-35B-A3B-Distill

llama.cpp

Not independently scored by Artificial Analysis — its base model Qwen/Qwen3.6-35B-A3B is the closest proxy

A 35B MoE with 3B active (apache-2.0), distilled from Qwen3.8 by a small lab, with its own GGUF.

First-party test · not the AA coding index

BigCodeBench-Hard pass@1 29% (43/148), via official protocol · llama.cpp Q4_K_M · one request at a time · a shared cluster GPU · mean of 3 runs, range 0.0 pp. The brutal counterpart to HumanEval — where HumanEval saturates near the top, BCB-Hard spreads the field, so this is the number that actually separates coding ability.

What we measured

Our own runs on this model. Each number carries how many problems it is over and how many times we ran it — these are not comparable with each other, and none of them is on the same scale as the third-party indices on the leaderboard.

Config tips

29.0% over three runs with only 3B active parameters: that is the cheapest way in this catalogue to buy that score, because an A3B MoE runs at the speed of a 3B while weighing like a 35B. Watch the file size, not the parameter count.
