Free users now get unlimited text chats on GPT-5.6 Luna, cutting factual errors by 62% vs GPT-5.5, while Plus/Pro users get GPT-5.6 Sol with 68% fewer errors and a "thinking slider" for adjustable reasoning depth. This means your production agents can rely on cheaper, higher-accuracy models for most text tasks, but you’ll need to retest rate limits on non-text features (files, images, voice) and validate whether the new models’ compact answers break existing prompt chains or output parsers.
GPT-5.6 Luna reduces factual errors by 62% over GPT-5.5 for free users, enabling more reliable unlimited text chats. This allows free-tier services to handle complex queries with higher accuracy, reducing the need for paid tiers for basic fact-based tasks while maintaining quality.
