Greg Brockman, OpenAI co‑founder and chief technology officer, testified Tuesday in Elon Musk's lawsuit against the artificial‑intelligence lab. During cross‑examination and direct examination, Brockman detailed early meetings with Sam Altman, described the $10 billion Microsoft investment as the only ten‑billion‑dollar infusion, and disclosed financial ties to Cerebras, Stripe, CoreWeave and Altman's family office. His answers, filled with precise language and frequent clarifications, have become the trial's most substantive evidence of internal decision‑making and potential conflicts of interest.

Amazon invited a journalist on a private tour of its Austin chip lab, showcasing the development of the Trainium AI processor family. Lab leaders Kristopher King and Mark Carroll explained how Trainium, originally built for training, now powers inference for services like Bedrock and supports major partners such as Anthropic, OpenAI, and Apple. The lab’s work includes custom servers, liquid‑cooled chips, and a mesh network that reduces latency. Engineers described the intense silicon bring‑up process, welding stations, and a private testing data center. CEO Andy Jassy highlighted Trainium as a multibillion‑dollar business driving AWS’s AI strategy. Lire la suite

OpenAI has teamed with Cerebras to run its Codex-Spark coding model on the Wafer Scale Engine 3, a chip the size of a dinner plate. The partnership aims to improve inference speed, delivering roughly 1,000 tokens per second, with higher rates reported on other models. The move reflects OpenAI’s broader strategy to reduce reliance on Nvidia by striking deals with AMD, Amazon and developing its own custom silicon. The faster coding assistant arrives amid fierce competition from Anthropic, Google and other AI firms, underscoring the importance of latency for developers building software. Lire la suite

OpenAI unveiled Codex‑Spark, a lightweight version of its Codex coding assistant designed for rapid inference and real‑time collaboration. The new model runs on Cerebras' Wafer Scale Engine 3, a megachip featuring four trillion transistors, marking a deeper hardware integration between the two companies. Currently in a research preview for ChatGPT Pro users, Spark aims to accelerate prototyping while complementing the heavier, longer‑running tasks of the original Codex model. Lire la suite

OpenAI announced a multi-year agreement with AI chipmaker Cerebras to deliver 750 megawatts of compute power from this year through 2028. The partnership, valued at over $10 billion, aims to accelerate real‑time inference and improve response times for OpenAI’s customers. Cerebras’ low‑latency hardware will complement OpenAI’s existing compute portfolio, providing faster, more natural interactions for AI applications. Both companies highlighted the strategic fit, noting that the deal strengthens OpenAI’s infrastructure while showcasing Cerebras’ advanced chip technology. Lire la suite
