--- title: "Qwen3.8 Max API: facts and benchmarks | Kendr" canonical: "https://kendr.org/models/kc-qwen3.8-max" date_modified: "2026-08-12" profile_kind: "hosted" --- # Qwen3.8 Max API model profile Qwen3.8 Max is a Alibaba Qwen model profile with a 1,000,000-token context window. The dated catalog snapshot records text, image, video modalities and interfaces for agentic, coding, prompt caching, reasoning, reasoning controls. Qwen3.8 Max is available under the Kendr alias kc-qwen3.8-max. Current account availability and customer credit quotes come from Kendr's live public model API and applicable account policy. Qwen3.8 Max accepts text, image, and video and returns text. The snapshot records agentic, coding, prompt caching, reasoning, reasoning controls, structured output, text generation, tool calling, tools, video input, and vision as capabilities or interfaces. The dated reference snapshot lists $2 input and $6 output per million tokens. Cached input is $0.25 per million tokens. The separately published provider-route reference is $2 / $6 ($0.25/M implicit cached input). The 2026-08-12 snapshot includes 3 Artificial Analysis indexes. Publisher-reported launch results are labeled and are not presented as Kendr measurements; scores from different suites are not treated as interchangeable. Qwen3.8 Max ranked #33 in the cited trailing-7-day third-party catalog usage dataset as of 2026-08-12. Observed within the cited trailing-7-day third-party catalog usage dataset; this is not global AI market share. Profile data was reviewed for the 2026-08-12 snapshot. Claims retain their source dates, and unavailable fields are shown as unavailable instead of estimated. ## Profile facts - **Profile type:** Kendr API model - **Kendr API alias:** kc-qwen3.8-max - **Model developer:** Alibaba Qwen - **Kendr route provider:** QwenCloud - **Context window:** 1M - **Snapshot date:** 2026-08-12 - **Reference catalog ID:** qwen/qwen3.8-max ## Context, modalities, and identity Qwen3.8 Max accepts text, image, and video and returns text.
