OpenAI launched GPT-5.3-Codex-Spark, its first model powered by Cerebras silicon. Delivering 1,000+ tokens per second, it is 15x faster than previous models and advances a 10 billion dollar hardware diversification strategy. Shifting inference to specialized wafer-scale engines enables near-instant agentic workflows. This systemic move de-risks OpenAI’s supply chain while setting a new industry standard for real-time performance. 🚀
