OpenAI GPT-5.3-Codex-Spark Now Running at 1K Tokens per Second on Cerebras Chips (www.servethehome.com)

OpenAI has unveiled its latest model, GPT-5.3-Codex-Spark, designed as a groundbreaking coding assistant that achieves an impressive performance of 1,000 tokens per second on Cerebras chips. This marks the first collaboration between OpenAI and Cerebras, and it sets a new standard in AI capabilities. During a demonstration, GPT-5.3-Codex-Spark quickly completed a "build a snake game" task in just 9 seconds, while the previous model took nearly 43 seconds. The Spark model not only offers speed but also higher quality than its predecessor, GPT-5.1-Codex. The significance of this rollout for the AI/ML community lies in its potential to accelerate workflow efficiency and enhance productivity in software development. Utilizing the Cerebras Wafer-Scale Engine 3 (WSE-3), which can harness large chips without the limitations of traditional designs, the collaboration promises even faster inference times. This advancement could transform how developers approach coding tasks, allowing complex projects to be completed in mere seconds using simple prompts instead of extensive coding skills. As AI continues to evolve, the implications for future applications and the ease of turning ideas into reality are profound, suggesting a paradigm shift in development practices.
