Qwen 3.8 27B is excellent, but it defaults to wildly overthinking things

Qwen 3.8 27B defaults to "xhigh" reasoning effort, burning 22k+ tokens and 21 minutes to generate a single SVG—20x slower than with reasoning off. This matters because it silently tanks throughput and spikes costs on consumer hardware; if you ship this in production, you’ll need to explicitly cap reasoning effort or risk unpredictable latency and token waste.
The newly released Qwen 3.8 27B model defaults to an "extra high" reasoning setting that can consume over 22,000 reasoning tokens for simple prompts, easily exceeding standard 8,192-token context limits and spiking generation times to over 20 minutes. If you deploy this model in production pipelines, you must explicitly override the default reasoning effort parameter or expand your context window to avoid catastrophic latency bottlenecks and immediate runner failures on routine tasks.
