## Summary

[Openai](/en/entity/openai) expanded its ChatGPT free and Go tiers on August 6, giving users unlimited text chats powered by GPT-5.6 Luna, a variant of the GPT-5.6 model generation. [Chatgpt](/en/entity/chatgpt) paid-tier users running GPT-5.6 Sol received simultaneous improvements to that variant. The rollout also adds a "think" button for complex queries, giving free users access to a reasoning-first mode previously limited to paid plans. TechCrunch reported the update as a straightforward tier expansion. Unite.AI noted that OpenAI maintained a distinction between Luna (free) and Sol (paid) even as it broadened access to the model generation.

## Why it matters

Making GPT-5.6 available to free users accelerates competitive pressure on Google, Meta and Anthropic to lower access barriers to their own frontier models. The simultaneous Sol improvement signals OpenAI is trying to preserve a paid-tier quality gap even as it democratizes access, a balance the company has revisited repeatedly since [OpenAI launches ChatGPT Work and merges Codex into a redesigned desktop app alongside GPT-5.6](/en/n/openai-chatgpt-work-0709).

## What to watch
- Whether Google and Meta respond with free-tier upgrades to their own frontier models
- How OpenAI manages capacity as free-tier usage scales up with unlimited text access
- The practical performance difference between GPT-5.6 Luna and GPT-5.6 Sol under real workloads
