Percentile boundaries are computed across every model in the tree that reports the underlying benchmark for each capability.
What it feels like
- First-generation Qwen — historical; superseded by 2.5+.
- First open-source model to top OpenCompass leaderboard — beat Llama 3.1 405B with 1/5 the parameters
- 72B-Instruct: 74.2 on coding, 77 on math — outscored Claude 3.5 Sonnet (72.1) and GPT-4o (70.6) at release
- MMLU 85+, HumanEval 85+, MATH 80+ — frontier-tier across the board for an open-weights model
Best use cases
- Self-hosted production where Llama 3.1 405B is too big to serve
- Multilingual deployments (29 languages with strong coverage)
- Fine-tuning on private code or technical corpora
Tools to try
Not ideal for
- Frontier reasoning by mid-2025 — Qwen 3 / DeepSeek R1 / Claude 4 series have moved past it
- Vision tasks (use Qwen 2.5-VL) or audio (use Qwen 2.5-Audio)
