OpenAI has released GPT-5.3-Codex-Spark, its first model powered by Cerebras Systems hardware as part of a 10 billion dollar deal. Utilizing the Wafer-Scale Engine 3, the model achieves inference speeds of 1,000+ tokens per second, approximately 15x faster than GPU clusters. This breakthrough enables real-time code generation and instant execution, marking a systemic shift toward specialized silicon for agentic workflows. By bypassing memory bottlenecks, OpenAI is redefining the AI compute stack. 🚀
