What is SambaNova?
SambaNova designs its own inference chip, the Reconfigurable Dataflow Unit, and sells fast tokens on large open models through SambaCloud. The RDU maps the model graph onto the chip to cut trips to off-chip memory. A three-tier memory design of SRAM, HBM and bulk DRAM lets one system host very large models and hot swap between several of them in milliseconds. SambaCloud serves models like MiniMax M2.7, DeepSeek, Gemma 4 31B and GPT-OSS 120B, with speeds reported by Artificial Analysis.
The fifth-generation SN50 chip, announced in February 2026, starts shipping in the second half of the year. SambaNova claims 5x the peak speed of an NVIDIA B200 and support for models up to 10 trillion parameters with 10M token contexts, all in a 20 kW air-cooled rack. Its August 2026 pitch leans into what it calls premium inference: GPUs handle prefill, RDUs handle decode, and a SambaRack SN50 runs MiniMax M2.7 near 820 tokens per second in its fastest configuration. SambaNova also sells racks to neoclouds that want to offer a fast tier without replacing their GPU fleet.
SambaNova pros, cons and use cases
Upsides
- Fast decode on large frontier-scale open models, where Groq and Cerebras have thinner catalogs.
- Millisecond model hot swapping and input caching suit agents that bounce between models.
- Air-cooled racks fit existing data centers.
Core use cases
- Interactive coding agents and copilots on big open models.
- Neoclouds adding a premium speed tier through disaggregated prefill and decode.
Downsides
- Smaller public catalog than GPU clouds, and many headline numbers are vendor benchmarks on hardware still ramping.
- Much of the value arrives through hardware sales and partnerships rather than a big self-serve developer platform.
