  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 1,000,000 tokens."). Review 2026-10-01: Tools: the Qwen3.8 GitHub README serves Qwen/Qwen3.8-27B with "--enable-auto-tool-choice --tool-call-parser qwen3_coder". No structured-output support documented. The card recommends setting the maximum output length to 262,144 (reasoning) / 131,072 (final response) tokens; that is a serving recommendation, not a stated model limit.
