  Image input follows the Hugging Face pipeline tag and the card type; tool and structured-output support were not verified. Context from the "Context Length" line of the model card ("Context Length: 262,144 natively and extensible up to 1,010,000 tokens."). Review 2026-10-01: Tools: the card's Agentic Usage section says "Qwen3.5 excels in tool calling capabilities." No structured-output support documented. The card recommends an output length of 32,768 tokens for most queries; that is a usage recommendation, not a stated maximum, so maxOutput is recorded as not published.
