Qwen: Qwen3.5 Plus 2026-02-15

Qwen3.5 Plus 2026-02-15 is a multimodal model from Qwen that accepts text, image, and video inputs, with a context window of 1,000,000 tokens and a maximum of 65,536 output tokens per completion. It supports tool use and reasoning, which makes it applicable to agentic workflows and multi-step tasks. Structured output support is unconfirmed based on available data. At $0.26 per million input tokens and $1.56 per million output tokens, the pricing sits at a moderate tier, though value is difficult to assess objectively because there is currently no independent benchmark coverage. Buyers who need long-context multimodal processing with tool and reasoning support may find it worth evaluating, but those who require verified performance data before committing should note that Qwen3.5 Plus 2026-02-15 is effectively unproven on third-party benchmarks at this time.
