July 10, 2026 — OpenAI just dropped one of its biggest updates ever. The company has officially launched ChatGPT Work, a full-fledged AI work agent, alongside the complete rollout of the GPT-5.6 model family (Sol, Terra, and Luna). This is the AI news that is dominating headlines today — and for good reason.
What Is ChatGPT Work?
ChatGPT Work is not your usual chatbot. It is an AI agent built with Codex technology that can gather context from your apps (Slack, Google Drive, Microsoft 365, Notion, and more), then produce finished documents, spreadsheets, presentations, reports, and even interactive web apps. Think of it as having an entire virtual assistant that actually finishes the work, not just starts it.
The agent can run complex workflows that take hours — breaking them into smaller steps, working in the background, and checking in with you only when needed. It can even run scheduled tasks while you are offline, like refreshing a weekly report or monitoring dashboards for changes.
OpenAI says nearly 100% of internal teams at the company — including finance and sales — now use ChatGPT Work. Finance teams reportedly cut month-end close from days to hours. Sales teams turned discovery conversations into proof-of-concept proposals within 24 hours, a process that normally takes weeks.
GPT-5.6: Sol, Terra, and Luna — The Model Family
Powering ChatGPT Work is the new GPT-5.6 family, available in three tiers:
- GPT-5.6 Sol ($5M input / $30M output tokens) — Flagship model, state-of-the-art across coding, knowledge work, cybersecurity, and science. Outperforms Anthropic Claude Fable 5 on the Coding Agent Index (80 vs 77.2) while using less than half the output tokens and costing about one-third less.
- GPT-5.6 Terra ($2.50M input / $15M output tokens) — Balanced model for everyday work. Performs just above Fable 5 at roughly one-sixteenth the cost.
- GPT-5.6 Luna ($1M input / $6M output tokens) — Fast and affordable, outperforming Opus 4.8 while being drastically cheaper.
CEO Sam Altman told CNBC that Sol is 54% more token-efficient on coding tasks compared to previous models. The model also sets new records on BrowseComp (92.2%) for agentic browsing and OSWorld 2.0 (62.6%) for computer use tasks.
Why It Matters
This launch is a direct shot at Anthropic, whose Claude Fable 5 has been gaining enterprise traction. OpenAI is making the case that GPT-5.6 delivers stronger performance at a fraction of the cost. The timing is also notable — the rollout was delayed by two weeks after a U.S. government review over cybersecurity concerns, particularly about Sol frontier-level capabilities in threat modeling and code analysis.
OpenAI also announced GPT-Live, a new generation of voice models that supports natural back-and-forth conversation (interruptions, mhmm acknowledgments, and simultaneous listening and speaking), plus the merging of the Codex app into the ChatGPT desktop app. The standalone Atlas browser will be discontinued on August 9.
