OpenAI introduces ‘Ultrafast,’ a new mode that makes GPT-5.6 Sol work at 14x the speed
OpenAI is launching a preview of a sped up version of its latest, most powerful model, in an effort to court enterprise users.
OpenAI has launched a new mode called Ultrafast for its latest model that processes information at 14 times the standard speed, generating up to 750 output tokens per second. The company positions this as progress toward delivering more useful work per second while maintaining the power of its most advanced model, addressing the historical tradeoff where faster speeds typically required using smaller or more specialized models. The feature is currently available in preview to a limited group of customers and is powered by a partnership with chipmaker Cerebras, with plans to expand access as capacity grows. OpenAI suggests Ultrafast can be deployed across corporate workflows including incident response, customer service, financial market analysis, and e-commerce, while competitors like Anthropic offer similar accelerated versions of their own models.

Google Launches Gemini Decisions API With Gemini Decision 1 at $0.10/M Tokens
Google has launched the Gemini Decisions API, powered by a new model, Gemini Decision 1 (gemini-decision-1). The Gemini Decisions API does not generate text. It scores up to 1,000 typed questions against one shared input and returns calibrated probabilities. For developers, this targets the small branching calls inside agents: routing, policy checks, tool selection and grading. Google prices it at $0.10 per 1M input tokens, with zero output tokens billed. TL;DR Size: Context is 262,144 t

Google releases Gemini 4 Carbon with agent ‘swarm’ feature
Google is rolling out its latest AI model, Gemini 4 Carbon, to the general public after releasing it to a select group of "cybersecurity defenders" two weeks ago. Google claims Carbon is its "strongest model" yet, and capable of competing with the very best systems from Anthropic and OpenAI. Google says Gemini 4 Carbon "pushes the frontier even further" than Argon, referring to the company's other frontier model that launched only last month. The company said Argon will likely
