What is Ultrafast Mode in AI?
Ultrafast mode is a new service tier that runs GPT-5.6 Sol up to 14× faster than Standard processing, generating up to 750 output tokens per second. This mode is powered by Cerebras and brings advanced intelligence to products and workflows where every second matters. It has the potential to transform various industries such as finance, commerce, and customer support.


The arrival of Ultrafast mode is a major breakthrough in AI development - it's a game-changer. By harnessing the power of Cerebras, OpenAI has managed to push the boundaries of what's possible with AI, allowing it to process information at mind-boggling speeds. This has huge implications for a wide range of industries, from finance to commerce, and even customer support. With Ultrafast mode, AI can now tackle the most time-sensitive aspects of a business, enabling real-time decision-making and transforming the way companies operate - it's a whole new ball game.
One of the key advantages of Ultrafast mode is its ability to generate up to 750 output tokens per second - that's incredibly fast. This means AI can now analyze vast amounts of data in a matter of seconds, rather than minutes or hours. This could revolutionize industries like finance, where rapid analysis of market signals and transactions is critical. It also has significant implications for customer support, where AI can now resolve complex issues in real-time, without interrupting the conversation - a major win for customer experience.
OpenAI is already working with a group of customers to see where Ultrafast mode makes the biggest impact, and how these insights can shape their products over time. Some early customers have reported that Ultrafast mode has been a total game-changer in their voice stack, completely transforming the call experience for complex work. Others have noted that it enables developers to work more efficiently alongside AI models - a big plus for productivity. As the tech continues to evolve, it'll be exciting to see the new use cases and applications that emerge - the possibilities are endless.

Google DeepMind Verifies Signal Protocol With AI In Four Weeks
Google DeepMind researchers used an AI system called AlphaProof Code to mathematically verify core cryptographic guarantees of the Signal protocol in a four-week proof-of-concept. The protocol secures communications in Signal, WhatsApp, and Google Messages. The system found no new vulnerabilities in current versions and correctly identified known flaws in older versions. DeepMind published the formal specifications and proofs, marking a milestone for AI-assisted formal verification, th

Google DeepMind Launches AlphaGenome 2 for Cell-Specific DNA
Google DeepMind launched AlphaGenome 2 November 11, 2026, a model predicting how DNA variants affect specific human cell types. Unlike its predecessor averaging tissue-level data, this conditional model processes one cell type at a time, identifying nearly twice as many expression-altering variants. Trained on 107 million cell profiles across 68 tissues, it predicts gene expression, chromatin accessibility, and transcription factor binding. Available via API for non-commercial research
