OpenAI Built Its Own Chip in 9 Months, Fable 5 Is Coming Back, AI Is Trying to Kill the Common Cold

Today we're covering the biggest AI stories of June 25th, 2026. OpenAI revealed Jalapeño — its first custom inference chip built in partnership with Broadcom in just nine months, with OpenAI's own AI models helping in the design process and early testing showing performance per watt substantially better than current state-of-the-art — a major step toward owning the full stack from silicon to product without leaning on Nvidia. Fable 5's return is starting to take shape — Claude Code update logs reference Fable usage, the White House is reportedly "happier" in talks now that co-founder Tom Brown has replaced Dario Amodei as the point person, and the first lawsuit against the ban was filed calling it unlawful government retaliation, with Congress giving Commerce until today to explain when the public gets Fable back. Plus, Stripe, Anthropic, and the OpenAI Foundation joined a $500 million nonprofit called Intercept to fund shots, sprays, and air-cleaning tech aimed at making the common cold and flu a thing of the past — and today's community workflow comes from Steve in Troy, New York, who used Claude to build a voice-based social practice app for a young family member with selective mutism, letting her practice conversations with different characters in realistic settings, and she's already using it.
