Qwen shipped Qwen3.8-27B weights on Friday: dense 27B, Apache 2.0, 262K context, text + image input—and half of ML Twitter spent the weekend benchmarking it.

Published scores are striking: 61.7 on SWE-bench Pro (vs Claude Opus 4.6 Max at 53.4), 90.3 on LiveCodeBench v6 (88.8), 84.3 on OSWorld-Verified (72.7), and 89.2 on GPQA Diamond, beating Claude's flagship on several benchmarks.

It's already live on Chutes at $0.40/M input and $3.00/M output tokens, served inside a hardware-attested TEE with end-to-end encryption.
