How Much Does the DeepSeek API Cost?
DeepSeek's API is known for low per-token prices — which makes it popular for agent fleets. Low price × high volume is still a real bill.
How DeepSeek pricing works
Per-token pricing by model, with input/output rates and a cache-hit discount for repeated context.
Prices are among the lowest in the market, which invites scale.
The hidden cost: volume and retries
Cheap tokens encourage long, repeated runs. A retry loop on a cheap API still compounds.
Cache misses on large shared contexts bill at full input rate.
Agent fleets that spawn hundreds of runs multiply even cheap per-token rates.
What it really costs
Model rate × volume × context. At DeepSeek prices, volume is the lever — and volume is exactly what autonomous agents generate.
Where the money goes
| Lever | What it controls | Tool |
|---|---|---|
| Model choice | Per-token rate | Route to appropriate model |
| Retry loops | Multiplied volume | Velocity limits |
| Per-agent budget | Fleet total | Daily ceilings |
| Merchant scope | Which vendors | Merchant allowlist |
FAQ
Is DeepSeek cheaper than other APIs?
Generally yes on per-token rates — but total cost is rate × volume. Cheap tokens at runaway volume are still expensive.
Do cache discounts apply to agents?
Cache-hit discounts apply to repeated context. Agent workflows with stable system prompts can benefit — but cache misses bill full rate.
Can sipi.bot control DeepSeek spend?
Yes — category rules, per-agent ceilings, and velocity limits apply to any API merchant your agents call.
