Cerebras

Introduces OpenAI's GPT-5.3-Codex-Spark model, powered by Cerebras, for real-time software development. Achieves over 1,000 tokens/s for near-instant feedback in live coding environments. Codex-Spark is optimized for fast inference and excels at precise edits, revising plans, and answering contextual questions about codebases, enabling faster iteration cycles for UI visualization, styling refinement, and interface testing. Highlights the Cerebras Wafer-Scale Engine's capability for high-speed inference at thousands of tokens per second per user, with scalability to multi-terabyte memory for trillion-parameter models.
