OpenAI has begun a limited preview of its GPT-5.6 series, introducing three models: Sol (flagship), Terra (2x cheaper than GPT-5.5 with competitive performance), and Luna (lowest cost option). The models are launching first with trusted partners before general availability in coming weeks, following U.S. government preview requirements.

Augment Code released Prism, a model routing system that selects between frontier models and cheaper alternatives per user turn. On internal benchmarks, Prism matches Claude Opus 4.7 and GPT 5.5 quality while reducing per-task costs by 20-30%, translating to approximately $20,000 monthly savings for teams sending 10,000 requests.

Microsoft has enabled its Copilot Researcher tool to simultaneously leverage OpenAI's GPT and Anthropic's Claude through two new features: Critique, which uses GPT responses refined by Claude, and Model Council, which displays side-by-side outputs with agreement/disagreement analysis. Both features are rolling out in the Microsoft 365 Copilot Frontier early access program.
