OpenAI details what to expect from the three new models in its GPT-5.6 preview

• OpenAI is starting to preview its new GPT-5.6 models: Sol, Terra, and Luna
• Sol promises enhanced performance at cybersecurity tasks, while resisting efforts to weaponize its output.
• Terra and Luna are balanced for efficiency and reduced cost of operation.

Right now, the introduction of new AI models is more politicalized than ever, following the abrupt government pushback against Anthropic’s Fable 5 and Mythos 5. Now that mess is only set to continue, as the White House sticks its nose all up in OpenAI’s business for the release of GPT-5.6. As we wait to see how all that will ultimately play out, OpenAI is now detailing exactly what we can expect from its new GPT-5.6 models.

We’re actually looking at a trio of models that make up this latest generation: Sol, Terra, and Luna, all arriving over the coming weeks.
