OpenAI Launches GPT-5.6 and ChatGPT Work, New Advances in Artificial Intelligence Models

What happened

OpenAI announced the global launch of GPT-5.6, an update to its family of artificial intelligence models now available in ChatGPT, Codex, and the OpenAI API. The rollout will occur gradually over 24 hours from its official announcement on July 9, 2026.

The GPT-5.6 portfolio consists of three main variants: Sol, Terra, and Luna, highlighting the Sol model, which has set new performance records in reasoning tasks, code analysis, and general knowledge while significantly reducing costs and execution times.

Alongside the model update, OpenAI launched ChatGPT Work, a specialized agent powered by Codex and GPT-5.6, designed to execute complete workflows across multiple applications and files, remaining active for extended periods to fulfill specific work objectives.

ChatGPT Work is already available on web and mobile versions for users on Pro, Enterprise, and Edu plans, and will soon be accessible for Plus and Business plans. On desktop, Chat, Work, and Codex functionalities are present across all plans, including free ones, with global coverage.

Why it matters

GPT-5.6 represents a significant evolution in efficiency and intelligence of foundational AI models. According to OpenAI, GPT-5.6 Sol outperforms the Claude Fable 5 model by 2.8 points on the Artificial Analysis Coding Agent index, while consuming less than half the tokens and time, and reducing costs by about one-third.

This progress is relevant for applications demanding precision and speed, including programming, data analysis, cybersecurity, and scientific sectors. The new ChatGPT Work agent reflects a trend toward much more integrated AI productivity tools, capable of managing complete projects and operating across multiple platforms, potentially transforming work dynamics and AI-assisted methodologies.

From a technological perspective, the incorporation of GPT-5.6 enhances OpenAI's product ecosystem, enabling a more powerful and cost-efficient experience for developers and enterprise users. This improvement may drive broader AI adoption for complex and long-term tasks, reinforcing OpenAI's competitive relevance in the market.

What remains to be confirmed

Although the comparison metrics released by OpenAI indicate a clear technological advantage of GPT-5.6, no independent data or critical third-party analyses have been published to externally validate these claims. The internal technical characteristics of Sol, Terra, and Luna, as well as possible limitation scenarios or risks associated with their use in real production environments, are not extensively detailed.

Additionally, the concrete impact and commercial reception of ChatGPT Work across different user segments and markets will need to be observed in the coming weeks to measure its real adoption and utility.
