How AI reasoning effort settings compare across ChatGPT, Claude, Qwen, and Grok

Reasoning effort settings determine how many internal tokens a model spends before producing an answer, influencing answer quality, response time, and expense. The article recommends medium as a default for most tasks, with low or off for simple high-volume work and xhigh or max reserved for long agentic runs that show measurable improvement. It notes that OpenAI, Anthropic, Qwen, and xAI expose the same basic control under different names and defaults.

Expanded Detail

EXPANDED:

"Reasoning effort governs how many internal tokens a model uses for deliberation, tool use, and final output; those hidden reasoning tokens are charged as output. Vendors expose the same concept differently: OpenAI and xAI say reasoning effort, Anthropic says effort, and Qwen pairs thinking mode with effort levels. App labels include ChatGPT’s Instant-to-Extra-High range, Claude’s Effort menu, and Grok’s Fast, Expert, and Heavy options."

Second:

"Defaults vary: medium for GPT-6.1 Sol and Claude Opus 5.5, high for Grok 4.7, and xhigh for qwen3.8-max. Artificial Analysis data for GPT-6.1 Sol shows low-to-medium gains six index points for $0.08 more per task, while later steps add fewer points at higher cost. Output speed remains roughly 49–56 tokens per second; higher effort takes longer because more tokens are generated."
