| Native context | 262,000 tokens, extendable to ~1,010,000 tokens |
| Max input | 991K tokens (983K with thinking enabled) |
| Max output | 131K tokens |
| Vocab size | 248,320 |
| Precision | BF16 and FP8 weights available |
| Modality (open weights) | Text-only input/output |
| License | Custom revenue-share license; MaaS/AI Work Assistants with >$50M annual revenue must negotiate separately |
The open-weights checkpoint was published on Hugging Face and ModelScope .
Alibaba reported Qwen3.8-Max as "second only to Fable 5" among tested systems . Key published benchmarks :
| Benchmark | Score |
|---|---|
| Terminal-Bench 2.1 | 86.6 |
| GPQA Diamond | 92.6 |
| SWE-bench Pro | 67.7 (vs. Fable 5's 80.0) |
| FrontierSWE | 73.8 (vs. Fable 5's ~80+) |
Important caveat: These are Alibaba's internal runs. No independent benchmarks from Artificial Analysis or LMArena were available as of August 12 . On core coding tasks, Qwen3.8-Max trails Anthropic's Fable 5 by a meaningful margin .
| Service | Price |
|---|---|
| Input tokens | $2.00 per million tokens |
| Output tokens | $6.00 per million tokens |
| Implicit cache reads | $0.25 per million tokens |
| Explicit cache creation | $2.50 / $0.17 read |
The open-weights model itself is free to download, but the license restricts commercial MaaS usage above a $50M revenue threshold, pushing high-revenue users toward a paid commercial agreement .
The open-weights Qwen3.8-2.4T-A95B is a stripped-down subset of the full Qwen3.8-Max cloud model:
