GPT-6 with Intelligent UI rolls out to ChatGPT Chat tab across tiers

OpenAI is rolling out GPT-6 with Intelligent UI globally to Plus, Pro, Business, and Enterprise users today, with Free and Go users following starting tomorrow. Plus, Pro, Business, and Enterprise tiers are powered by GPT-6 Sol, while Free and Go tiers use GPT-6 Luna, and both are tuned for everyday conversation. The update applies only to the Chat tab, and the models powering Work and Codex are not changing.
