What commenters are saying
Several commenters note the price cut is limited to OpenRouter and may be an A/B test or ad, not a direct OpenAI API price reduction. Some question who subsidizes it and whether thinking traces provide value. A split emerges: some find GPT-5.6 Sol overcomplicates simple tasks and requires strict steering, while others praise its planning and diagnosis abilities when effort is set appropriately. Two pro-tips: use Luna or low thinking effort for simple tasks, and set an explicit thinking budget instead of default high.
