OpenAI Upgrades ChatGPT With GPT-5.6 Luna, Slashes Prices Amid Chinese AI Competition
Summary
OpenAI upgrades ChatGPT with GPT-5.6 Luna, cutting factual errors by 62% and slashing prices at an unprecedented pace as competition from cheaper Chinese AI models intensifies.
Key Points
- OpenAI is upgrading ChatGPT for all users by shifting the default model to GPT-5.6 Luna, which produces 62% fewer factual errors compared to the previous default model GPT-5.5 Instant.
- Free and Go plan users are receiving unlimited text chats and a new 'Think' button for higher reasoning, while Plus and Pro users get an improved GPT-5.6 Sol model with a new 'slider' tool to control how much thought ChatGPT applies to answers.
- Facing pressure from cheaper Chinese open-weight models, OpenAI is aggressively cutting prices on its GPT-5.6 Luna and Terra models just weeks after launch, a much faster timeline than previous price reductions.
