OpenAI launches GPT-5.6 family, pushing coding efficiency and cybersecurity

OpenAI launches its new family of models with GPT-5.6

OpenAI dropped GPT-5.6 in three tiers: Sol (workhorse), Terra (mid-range), and Luna (budget). Sam Altman told CNBC Sol is 54% more token-efficient on coding tasks. The company calls it their strongest cybersecurity model yet, covering threat modeling, code review, and blue teaming. The Trump administration previously tried to restrict its rollout over misuse fears. ChatGPT Work, an enterprise companion tool, also launched. The post doesn't disclose pricing or availability dates.

Why it matters: OpenAI flagship model refresh with two concrete hooks — 54% token efficiency gain and a cybersecurity positioning — via TechCrunch exclusive. Not a 95 because pricing and rollout timeline are missing; Sol's real inference cost is still unknown.
