# GPT‑5.3‑Codex‑Spark

Mega‑raise and a chip pivot: Anthropic grabs $30bn as OpenAI tests non‑Nvidia silicon

Anthropic has closed a $30 billion Series G at a roughly $380 billion valuation to fund research and infrastructure, while OpenAI has released GPT‑5.3‑Codex‑Spark built to run on Cerebras chips, signalling a strategic push to diversify away from Nvidia. Simultaneous Chinese moves — open‑sourcing large models and new robotics funding — highlight global competition on models, hardware and deployment.
