OpenAI launches ChatGPT Work: persistent agent combining ChatGPT and Codex, powered by GPT-5.6 Sol
Key Questions
What is ChatGPT Work and what does it enable?
It is a persistent agent merging ChatGPT and Codex for complex, long-running workflows in coding, writing, and knowledge work. Powered by GPT-5.6 Sol, it supports multi-step tasks and remote access via the mobile app.
What performance claims has OpenAI made for GPT-5.6 Sol?
Altman reported 54% greater token efficiency on agentic coding tasks. The model also solved a 50-year-old math conjecture using 64 subagents in under an hour.
What safety concerns arose with the GPT-5.6 Sol release?
A serious incident occurred when the model accidentally deleted a user's Mac files. This highlighted ongoing reliability challenges in agentic systems.
How has GPT-5.6 been received in Microsoft products?
It is now the preferred model in Microsoft 365 Copilot, with Satya Nadella praising its performance. Integration continues alongside Microsoft's own model development.
What other product updates accompanied the ChatGPT Work launch?
OpenAI announced Build Week Challenge events and noted growing adoption of ChatGPT Voice. François Chollet highlighted the rapid progress in agentic coding capabilities.
OpenAI launched ChatGPT Work, merging ChatGPT and Codex into a persistent agent for complex, long-running tasks. Powered by GPT-5.6 Sol, it supports multi-step workflows, coding, writing, and knowledge work. GPT-5.6 Sol is now released, with Altman claiming 54% more token efficiency on agentic coding. GPT-5.6 Sol Ultra proved a 50-year-old math conjecture using 64 subagents in under an hour, a major research milestone. However, a serious safety incident occurred: GPT-5.6-Sol accidentally deleted a user's Mac files, raising reliability concerns. Codex is now accessible as a remote agent on the ChatGPT app, improving mobile coding. GPT-5.6 is now the preferred model in Microsoft 365 Copilot, with Satya Nadella endorsing integration. François Chollet remarks on astonishing speed of agentic coding progress. ChatGPT Voice is gaining traction as a natural interface. OpenAI announced Build Week Challenge starting July 13. Practical tools: v0 deep dive with custom design systems. This marks a major product release in the agentic AI trend, with both breakthrough capabilities and safety challenges.
