The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
Alibaba Group's release is dated "August 3, 2026" and says "The model is now accessible via APIs on the Alibaba Cloud Model Studio for global developers, with model weights scheduled for release next week"; CNBC[6] reports Alibaba "unveiled" it "on Monday" 3 August.
Alibaba Cloud's model page: model ID qwen3.8-max, now the snapshot qwen3.8-max-0902 (alias qwen3.8-max-2026-09-02); image, text and video input; a 1,000,000-token context window with 131,072 max output; function calling, structured outputs, web search and context caching; CNY 12 input and CNY 36 output per million tokens in Beijing.[1]
Dates the cloud release to 3 August 2026, the open weights (Qwen3.8-2.4T-A95B, without image input or non-thinking mode) to 12 August, with a licence requiring providers earning more than US$50 million to get a commercial licence, and the Apache 2.0 Qwen3.8-27B to 14 August.[1]
Reports that Alibaba's Qwen team released Qwen3.8 Max Prime on 23 September 2026 as a higher-throughput version of Qwen3.8 Max at $4 per million input and $12 per million output tokens, "exactly twice the price of the standard model", and that it was not measurably faster in OpenRouter's first measurements.[1]
The open-weights model card: "For the first time, Qwen3.8 brings a Qwen-Max-class model to open release"; 2.4T total and 95B activated parameters, 92 layers, 512 experts (10 routed + 1 shared), 262,144 tokens natively extensible to 1,010,000, and benchmarks against Opus 4.8, Fable 5 and GPT-5.6 Sol.[1]
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.

Benchmark scores on the card are reported under the Qwen3.8-Max product tier, which may differ from the raw open checkpoint. · source
Qwen3.8 Max needs 64 steps per task instead of 14, and input tokens grew 15x because the test resends the full conversation history to the model at each step.
Qwen3.8 Max is now attempting questions it previously would have declined to answer, and getting a lot of them wrong instead.

qwen3.8-max API moved to a new snapshot, qwen3.8-max-0902, and on 23 September Alibaba added Qwen3.8 Max Prime, a higher-throughput tier of the same model at twice the price[2][4]
