Where DeepSeek V3 sits on price
At $0.89 per million output tokens, DeepSeek V3 is a mid tier model — 2.5× cheaper than the median output price of $2.20, which puts it cheaper than 72% and pricier than 28% of the models we track. It sits 8th cheapest of the 16 DeepSeek models we track. Output is only 2.8× the input price, an unusually flat spread: long prompts hurt about as much as long answers, so prompt size is where the savings are.
What real workloads cost on DeepSeek V3
These three workloads are the ones teams actually run on a mid-priced model — a $0.89/1M model is not bought for the same job as one ten times the price.
| Workload | Per request | Per month |
|---|---|---|
| Support chatbot — 500 conversations/day (5K in / 1.4K out) Conversation history re-sent each turn — the classic prompt-caching win. | $0.0028 | $42.69 |
| Document pipeline — 10K docs/day (3K in / 500 out) Batch-friendly: no user waiting, so a ~50% batch discount usually applies. | $0.0014 | $422 |
| Small app — 1K requests/day (500 in / 150 out) The baseline most side projects actually run at. | $0.0003 | $8.81 |

› Is DeepSeek V3 worth the price?
DeepSeek V3 sits in the middle of the market (8 of 16 by price within DeepSeek). The honest test is a routing experiment: send the same 200 real requests to this model and to a tier below, and compare failure rate against the price gap — most teams find a majority of traffic never needed the pricier model.
