Codex Just Became Unlimited! Also GPT 5.6 Is Actually Really…

Editor's take

OpenAI appears to have subtly updated its Codex models, removing token limits for certain users, while also hinting at significant advancements in its GPT-5.6 development. This move is significant because it addresses a core limitation in large language model accessibility for complex coding tasks, potentially enabling more sophisticated AI-assisted development workflows. The distinction between Codex and the GPT series, especially with this "GPT-5.6" nomenclature, suggests a tiered approach to model capabilities and perhaps a more granular release strategy than previously assumed.

The implications of unlimited Codex access could be far-reaching for developers and companies relying on AI for code generation and analysis. It raises questions about how OpenAI plans to manage computational resources and potentially monetize such expanded capabilities. Furthermore, the mention of GPT-5.6, even if informal, signals ongoing, rapid progress within OpenAI's flagship models, underscoring the industry's relentless pace.

Future developments to monitor include the official release and detailed performance benchmarks for GPT-5.6, and whether the unlimited Codex access will be expanded to all users or remain a premium feature. The industry will also be watching how this impacts code quality, development speed, and the competitive landscape as other AI labs inevitably respond to OpenAI's advancements.
