OpenAI upgrading ChatGPT and Codex with two more GPT-6 models
Building on the recent rollout of Astra, OpenAI is expanding its GPT-6 lineup by introducing the new GPT-6 Sol and GPT-6 Luna models for ChatGPT and Codex.

Artificial intelligence pioneer OpenAI is continuing to scale its next-generation architecture at a rapid pace. Earlier this month, the company made headlines by releasing its first GPT-6 model featuring Astra, setting a new benchmark for advanced AI capabilities. Now, that ecosystem is growing even larger with the introduction of two additional models.
The latest update brings the GPT-6 Sol and GPT-6 Luna models to both ChatGPT and Codex. These new additions are designed to further enhance the platforms' performance, accuracy, and overall capability to handle complex reasoning and development tasks. Codex, in particular, continues to evolve as an essential utility for software engineers and technical creators.
This swift expansion of the GPT-6 family highlights the relentless pace of innovation in the generative AI sector. By continuously rolling out specialized and upgraded models, OpenAI aims to address a wider array of professional and everyday use cases, refining both conversational interactions and automated coding workflows.
For the global tech community and developers relying on these tools, the ongoing evolution of GPT-6 models translates to enhanced efficiency and deeper capabilities. As AI integration deepens across software development and daily tasks, these architectural improvements provide crucial performance boosts for professionals worldwide.
