Cerebras vs SambaNova (2026)
Updated March 10, 2026
Overview
Cerebras builds the world's largest AI chips—wafer-scale processors that contain millions of cores on a single silicon wafer. The Cerebras CS-2 system delivers massive parallelism for AI training and ultra-fast inference for open-source models. Through Cerebras Inference, developers can access some of the fastest LLM inference speeds available, particularly for Llama models.
SambaNova builds custom AI chips (RDU - Reconfigurable Dataflow Units) and provides a cloud platform for running LLMs with extremely fast inference speeds. Their SambaNova Cloud offers free-tier access to popular models like Llama and DeepSeek with industry-leading throughput.
