SambaNova Review 2026: The Chip Company That Runs DeepSeek-R1 671B on One Rack — Faster, Cheaper, No Training
SambaNova builds AI inference chips — its RDU (Reconfigurable Dataflow Unit) is the only non-GPU silicon that hosts full DeepSeek-R1 671B on a single rack: 198 tokens/sec at full precision. That's something Groq (SRAM memory wall) and Cerebras (single-wafer capacity) simply cannot do. Its cloud does 400-580 tok/s on Llama 3.3 70B with a free tier and prices from $0 to $4.5 per million tokens. The pitch: if you run big reasoning models at scale, this is faster and cheaper than GPUs — but it's inference-only, no training, no fine-tuning. Pick it for DeepSeek-R1 users, heavy inference workloads, and long-context agents.
1. What Is SambaNova?
SambaNova is an American AI chip startup (~$2.2B valuation) taking a different path from NVIDIA. Instead of GPUs, it makes the RDU (Reconfigurable Dataflow Unit) — an inference-specialized chip with a three-tier memory architecture:
- 520 MiB on-chip SRAM — fastest, holds active weights
- 64 GiB on-package HBM — fast, holds KV cache
- 1.5 TiB direct DDR DRAM — huge, holds the whole model
Because it can hold huge models, one rack of 16 SN40L chips runs the entire DeepSeek-R1 671B — the same model Groq can't fit (SRAM wall) and Cerebras doesn't serve in this config.
Memory hook: "The memory-architecture master of inference — models too big for others, one rack handles."
- DeepSeek-R1 671B: 198 tok/s on a single rack (16× SN40L)
- First non-GPU vendor to host R1 671B full precision
- Llama 3.3 70B: 400-580 tok/s on SambaNova Cloud
- Free tier, pricing $0-$4.5 per 1M tokens
- 1 rack ≈ 40 GPU racks — 3x faster, 5x more efficient
One-line take: "The fastest way to run big reasoning models — but inference only, no training."
2. Core Strengths
2.1 The killer: DeepSeek-R1 671B on one rack
- 198 token/s at full precision on 16 chips in a single rack.
- GPU setups need ~40 racks; SambaNova does it in one — ~3x faster, ~5x more efficient, projected rack throughput 20,000 tok/s.
- Groq can't (SRAM wall), Cerebras doesn't serve it in this config — exclusive.
2.2 Fast cloud, cheap, with a free tier
- SambaNova Cloud prices $0-$4.5 per million tokens, free tier available.
- Llama 3.3 70B runs 400-580 tok/s.
- Especially strong on reasoning models (DeepSeek R1, Qwen QwQ).
- Faster than competitors at 32K+ token contexts — a dataflow-architecture advantage.
2.3 Chips keep improving (SN50 coming)
The current SN40L is already strong; the SN50 (announced Feb 2026, shipping H2 2026) promises 5x compute and 4x network bandwidth, extending the lead on large reasoning models.
3. SambaNova Cloud Pricing (2026, USD)
| Tier | Price | One-liner |
|---|---|---|
| Free tier | $0 | Try it before you pay |
| Standard | $0 - $4.5 / 1M tokens | Varies by model |
| DeepSeek-R1 671B | Per-token | Exclusive single-rack hosting |
One SambaNova rack replaces ~40 GPU racks for R1 671B — 3x faster and 5x more efficient. On the cloud, $0 entry plus a free tier makes heavy reasoning affordable.
4. Weaknesses — The Fine Print
❌ Inference-only
RDU does no training and no fine-tuning — you can only run existing models.
❌ Smaller model catalog
Fewer models than Together AI or Fireworks, and less production-testing for general chat.
❌ Thinner docs
Documentation is lighter than Cerebras or Groq — a higher onboarding cost.
❌ Platform lock-in
To get the RDU advantage you commit to SambaNova Cloud or hardware.
❌ Chip generation in flux
SN50 isn't shipping until H2 2026; today you're on SN40L.
5. Who Should (and Shouldn't) Use SambaNova
6. Final Verdict & Scores
SambaNova is the specialist for running big reasoning models fast and cheap — and it has an exclusive: full DeepSeek-R1 671B on a single rack. 198 tok/s, one rack replacing ~40 GPU racks, a free-tier cloud doing 400-580 tok/s on Llama 3.3 70B, and long-context speeds competitors can't match. The trade-offs are real: inference only (no training/fine-tuning), a smaller catalog, thinner docs, and platform lock-in. If you live on DeepSeek-R1 or heavy long-context reasoning, this is the fastest and cheapest option around. If you need training or maximum flexibility, look elsewhere.
