DeepSeek V3.1 Terminus cost & VRAM calculator

What does DeepSeek V3.1 Terminus cost to run for your workload, and can you run it on your own hardware? Set your workload below - we compute per-provider API cost live and tell you honestly whether local hardware can run it.

LOCAL ISN'T PRACTICAL

This is where owning stops making sense

DeepSeek V3.1 Terminus is a 685-billion-parameter model. No rig an individual can buy runs it - so unlike a workstation GPU model, there's no break-even to compute. The honest answer for nearly everyone is the per-provider API cost below.

685B total, ~37B active per token (MoE) - same backbone as DeepSeek V3. Instruct/agent-tuned variant of V3.1-Base: improves language consistency (less mixed Chinese-English) and adds Code Agent + Search Agent tool-use. FP8 quantization. Open weights under MIT.

Your workload

Casual Power user Team of 5 Codebase task

DeepSeek V3.1 Terminus runs an always-on thinking mode. Reasoning (thinking) tokens are billed at the output rate ($15.00/M), so count them here to see the thinking portion of your bill.

API cost for your workload

Provider Rate ($/1M) Monthly cost
StreamLake $0.34 in · $1.03 out $0.01 cheapest
SiliconFlow $0.27 in · $1.00 out $0.01 cheapest

Monthly cost is an estimate from list prices and your workload - verify against the provider before committing. Cached fraction applies the cache rate to that share of input.

Can you run it locally?

NO - NO INDIVIDUAL RIG RUNS IT

DeepSeek V3.1 Terminus has no published quantization that fits a rig one person can buy, so there's no local-hardware recommendation and no break-even to compute. The honest answer is the per-provider API cost above.

685B total, ~37B active per token (MoE) - same backbone as DeepSeek V3. Instruct/agent-tuned variant of V3.1-Base: improves language consistency (less mixed Chinese-English) and adds Code Agent + Search Agent tool-use. FP8 quantization. Open weights under MIT.
