Beyond Nvidia: OpenAI Taps Cerebras for Lightning Code
12 Feb
Summary
- OpenAI launches GPT-5.3-Codex-Spark for rapid coding.
- New model uses Cerebras Systems hardware, a shift from Nvidia.
- Codex-Spark offers 15x faster generation speeds.
OpenAI introduced GPT-5.3-Codex-Spark on Thursday, a new AI model engineered for near-instantaneous coding responses. This model represents OpenAI's first major inference partnership outside of its established Nvidia-based infrastructure, instead utilizing hardware from Cerebras Systems, known for its low-latency AI processing.
The collaboration with Cerebras arrives during a complex period for OpenAI, marked by evolving relationships with chip suppliers, internal restructuring, and new ventures. The company emphasizes that GPUs remain foundational for training and broad inference, while Cerebras complements this by excelling in low-latency workflows.
