OpenAI announced that text chats with ChatGPT are no longer restricted for free users, with the default model upgraded to GPT-5.6 Luna, which outperforms GPT-5.5 Instant. Free and Go subscribers can also use a new thinking button for complex problems, but high-compute features like file uploads, image generation, and voice conversations remain limited.
