OpenAI opens GPT-5.6 to a chosen few: Sol, Terra and Luna in preview
The new generation lands first on the API and Codex, for trusted partners, with stronger reasoning, an ultra mode and new pricing rules.
OpenAI has shuffled the board again. The company has begun a limited preview of GPT-5.6, the next generation of its models, presented in three flavours with names that taste of the solar system: Sol, Terra and Luna. The promise is a jump in reasoning, coding, biology and even cybersecurity, plus a new ultra mode for the most demanding tasks.
For now, access is tight. During the preview, GPT-5.6 is available through the API and Codex only to a select group of trusted partners and organisations, with arrival in ChatGPT promised for later. There are also updated pricing rules and a more predictable prompt-caching system — technical details that, in practice, decide how much it costs to put these tools to work.
It is not just the model
In the same breath, OpenAI introduced GeneBench-Pro, a research-level benchmark for judging AI agents in computational biology, with harder and more realistic tasks. It is one more sign of where the race is heading: models that do not just chat, but try to solve concrete scientific problems.
For anyone living in Portugal and working with these tools, the pattern holds: the new features reach paying API users first and only later trickle down to the everyday user. It is worth not chasing every announcement and letting the dust settle. We had already covered OpenAI’s push into hardware and Codex, and this preview fits that strategy of occupying ground on every front. Official details are being posted on OpenAI’s site.
