Leaked OpenAI Models and Work Mode Details

Ben's Bites · rss · 2026-07-14

Ben’s Bites summarized a batch of new OpenAI updates, focusing on the so-called GPT-5.6 model series and the ChatGPT/Codex integration.

Key details include:

• The ChatGPT macOS App and Codex App have merged, introducing a new ChatGPT Work mode
• A new ChatGPT Sites plugin allows for website hosting with "Login with ChatGPT" support
• GPT-5.6 is split into three models: Luna / Terra / Sol, each with multiple thinking levels, plus a new Ultra mode that triggers more subagents
• Higher thinking levels consume credits faster; the author recommends using lighter modes for daily tasks
• Author's impressions: Sol leans toward UI and writing, Terra feels like a more controllable upgrade to 5.5, and Luna acts like a mini model but avoids failing on clear tasks
• OpenAI reportedly reset usage limits multiple times to fix bugs from the app merger and temporarily removed the 5-hour limit
• The new version performs better in Computer Use, capable of viewing screens, clicking buttons, and operating across apps
