Episode Details

Speed became a product today. OpenAI and Cerebras previewed Ultrafast mode for GPT-5.6 Sol at up to 750 tokens per second — roughly 14x the standard baseline — and the use cases OpenAI named read like a go-to-market roadmap: voice, support, commerce, live experimentation. Everything else today was about price: the Financial Times confirmed OpenAI and Anthropic are cutting model prices as Chinese rivals gain ground, while DeepSeek went the other direction and raised V4 Pro pricing by as much as 1,100%. Google shipped Gemini 3.7 Flash at half price — with a fuse on it that burns out January 1, 2027. Writer released Palmyra X6 and said enterprises are done chasing benchmarks. IBM put OpenAI into tens of thousands of consultants' bags. And AdRoll opened the first real B2B on-ramp to advertising inside ChatGPT — which brings a disclosure bill with it under EU AI Act Article 50.
