Ironwood chip

Google’s AI resurgence centers on the Gemini 3 large‑language model and the Ironwood TPU, touted for higher efficiency and data‑intensive scaling. The rollout sparked a 5% share jump, a $4.3 billion Berkshire stake, and a near‑70% YTD gain, outpacing rivals. Analysts credit Google’s integrated stack—hardware, cloud, and vast YouTube data—as a competitive edge, though they warn the advantage is narrow amid fierce rivals like OpenAI’s GPT‑5, Anthropic’s Opus 4.5 and Nvidia’s GPU dominance. Sustained R&D spending and rapid capacity scaling remain crucial for lasting leadership.
