Inference Momentum as AI Industry Leaders Choose Cerebras

Cerebras has experienced extraordinary growth since launching its inference service in late 2024. Over the past year, Cerebras has held the performance crown every single day, routinely demonstrating speeds more than 20X faster than Nvidia GPUs on open-source and closed source models.

“Since our founding, we have tested every AI inference provider across hundreds of models. Cerebras is consistently the fastest,” said Micah Hill-Smith, CEO of leading benchmarking firm Artificial Analysis.

Cerebras’ performance advantage has led to massive demand. New real-time use cases – including code generation, reasoning, and agentic work – have increased the benefits from speed and the increased the cost of being slow, driving customers to Cerebras. Today, Cerebras is serving trillions of tokens per month, in its own cloud, on its customers premises, and across leading partner platforms.

In 2025, AI leaders including AWS, Meta, IBM, Mistral, Cognition, AlphaSense, Notion and hundreds more have chosen Cerebras, joining enterprises and governments, including GlaxoSmithKline, Mayo Clinic, the US Department of Energy, the US Department of Defense. Individual developers have also chosen Cerebras for their AI work. On Hugging Face, the leading AI hub for developers, Cerebras is the #1 inference provider with over 5 million monthly requests.
