Cerebras vs Nebius: Inference & Compute Comparison

Cerebras Systems is a pioneering AI hardware company founded in 2015 by Andrew Feldman, Gary Lauterbach, Michael James, Sean Lie, and Jean-Philippe Fricker, who previously worked together at SeaMicro (sold to AMD for USD 334 million in 2012). The company revolutionized AI computing with its Wafer-Scale Engine (WSE), the world's largest chip that uses an entire wafer instead of cutting it into individual chips. The CS-3 system contains 4 trillion transistors across 900,000 AI cores with 44GB of on-chip SRAM, delivering 21 petabytes per second of memory bandwidth—7,000× more than NVIDIA's H100.

Cerebras offers both hardware systems and cloud inference services. The CS-3 hardware system is priced at approximately USD 2-3 million per unit, targeting large enterprises, research institutions, and well-funded AI labs. For more accessible options, Cerebras provides cloud-based inference with competitive rates: a Developer Tier at USD 0.10-0.60 per million tokens depending on model choice, making cutting-edge AI accessible without massive capital investments. Cloud training on CS-2 systems is available at USD 60,000 per week or USD 1.65 million per year.

Cerebras' wafer-scale architecture delivers 10-70× faster inference speeds than GPU-based solutions and achieved 210× speedup over NVIDIA H100 in carbon capture simulations. The on-wafer interconnect bypasses latency bottlenecks of multi-GPU setups, enabling simpler programming models and handling huge models without typical GPU memory constraints. While manufacturing yields and high costs present challenges, Cerebras' breakthrough technology addresses fundamental bottlenecks in AI computing, positioning it as a serious challenger to NVIDIA's dominance in the AI accelerator market.

Nebius Group is an AI cloud infrastructure company headquartered in Amsterdam, Netherlands, providing a unified platform spanning data processing, model training, and production deployment. Listed on Nasdaq (NBIS) with a USD 25.8 billion market capitalization and 1,371 employees, Nebius offers NVIDIA GB300, GB200, B300, B200, H200, and H100 GPUs. Current pricing includes B200 Blackwell GPUs at USD 2.69 per hour for preemptible instances, with up to 35 percent savings on on-demand rates for multi-month reserved clusters. The company has secured over 2 gigawatts of contracted power with expectations to reach 3+ GW by year-end, enabling massive scale. Nebius expects annualized revenue run-rate of USD 7-9 billion by end of 2026, up from USD 1.25 billion in 2025, with USD 2.1 billion in Q4 2025 capital expenditures. Amsterdam employees rate the company 4.5 out of 5 stars, praising great people, good salary, and interesting projects, though some cite work-life balance concerns and over 90 percent Russian language barrier for non-Russian speakers.
