Stop waiting on GPUs.

The world’s fastest AI teams — from code generation startups to frontier research labs — build, test, and launch on Cerebras inference, the only platform that runs models in real time.

Speed isn’t just performance — it’s your competitive advantage.

  • 15× faster inference for code, agents, and deep research workloads
  • Sub-second responses for real-time reasoning and agentic AI
  • From prototype to production without queues, lag, or limits

Performance comparisons are based on third-party benchmarking or internal testing. Observed inference speed improvements versus GPU-based systems may vary depending on workload, configuration, date and models being tested.
