Qwen: Qwen3.5 Plus 2026-04-20
Qwen3.5 Plus 2026-04-20 is a multimodal model from Qwen that accepts text, image, and video inputs and returns up to 65,536 tokens per response. Its context window reaches one million tokens, which suits tasks requiring long document processing or extended conversation history. The model supports tool use and reasoning, making it applicable to agentic workflows and multi-step problem solving. Structured output support is not confirmed for this version. At $0.30 per million input tokens and $1.80 per million output tokens, pricing sits in the budget-to-mid range for multimodal models with reasoning capability. The practical caveat is that there is currently no independent benchmark coverage, so quality relative to competitors is unverified. Buyers who prioritize a long context window, video input support, and tool use at a moderate price may find it worth evaluating, but teams that need benchmark evidence before committing should treat it as unproven until independent results become available.
