OpenAI launches GPT-5.6 family and consolidates desktop apps
3 min read
OpenAI launched the GPT-5.6 family with three tiers — Sol (flagship), Terra (balanced) and Luna (lightweight) — plus two new reasoning modes, Max and Ultra. Sol nearly matches Anthropic's Claude Fable 5 on one public index while leading coding benchmarks and costs about one-third per task versus that rival, and OpenAI published explicit per-token pricing for each tier. The company also merged Codex into a revamped ChatGPT desktop app to enable agentic workflows and ChatGPT Work for multi-step enterprise tasks, and briefly provided limited previews to government partners after cybersecurity requests, raising oversight questions.
OpenAI released three GPT-5.6 tiers with agentic desktop integration.
