OpenAI Unveils GPT‑5 Pro, 6GW AMD Deal

At DevDay OpenAI pushed to become a full‑stack developer platform, unveiling AgentKit — a no‑code visual Agent Builder with ChatKit, a Connector Registry and expanded evaluation tools — and an Apps SDK plus in‑ChatGPT MCP‑based apps that are being made available to most users. It announced major model and API updates including GPT‑5 Pro for high‑accuracy use cases, Sora 2 video generation, a lower‑cost, low‑latency voice model, and an updated Codex. OpenAI also struck a large supply agreement with AMD reportedly for roughly 6 gigawatts of Instinct GPUs and a warrant/option for about 10% of AMD stock while retaining its relationship with Nvidia. Markets cheered the deal, but analysts cautioned the agreements represent optionality rather than immediate delivered capacity and said massive datacenter expansion (OpenAI’s “Stargate”) will be needed for the company to meet potential GPU commitments.
