OpenAI shipped an improved GPT-5.6 Sol inside ChatGPT on Aug 6 and widened free-tier access to GPT-5.6 Luna, extending the same push toward broader, cheaper access that ChatGPT Work has been built around.

Earlier contextThe story so far

OpenAI's product lead traced ChatGPT Work's growth from Codex's 0-to-10M-user run to a full agentic assistant (Sites, Memory, Subagents, Finance, no-code) on Jul 28. An outside engineering write-up followed on Aug 4, reconstructing how Memory, Proactivity, Scheduling, Browser Use, Plugins, Skills, and Tools actually fit together inside the product.

What to watch — open questions

  • Does OpenAI publish an official architecture breakdown of ChatGPT Work's Memory/Scheduling/Browser-Use stack, or does the outside reconstruction stay the best public reference?
  • Does the wider GPT-5.6 Luna free tier carry the same agent capabilities (Memory, Subagents, Tools) as the paid ChatGPT Work tier, or is it a lighter separate product?
