Several major technology companies are releasing new AI models or updates this week, as the AI race promises to be hotter than the summer heatwave.
OpenAI is expected to make GPT-5.6 publicly available on Thursday, widening access to its latest and most capable AI model after an earlier limited rollout.
The company first unveiled GPT-5.6 in late June, but access was restricted to a small group of vetted partners while the US government reviewed potential national security risks.
Similarly to the release, withdrawal and subsequent re-release of Anthropic’s Fable model, US officials had raised concerns that increasingly powerful AI systems could be misused, including for cyber or military purposes.
OpenAI said in a post on X late Tuesday that it now plans to release GPT-5.6 Sol, along with its Terra and Luna models. Sol is the company’s most advanced model, while Terra is a lower-cost mid-tier option and Luna is its most cost-efficient version.
