Where DeepSeek V4.1 Flash (batch) sits on price
At $0.336 per million output tokens, DeepSeek V4.1 Flash (batch) is a budget tier model — 6.5× cheaper than the median output price of $2.20, which puts it cheaper than 85% and pricier than 15% of the models we track. It sits 3th cheapest of the 15 DeepSeek models we track. Output is only 3.0× the input price, an unusually flat spread: long prompts hurt about as much as long answers, so prompt size is where the savings are.
Cached input is 97% cheaper. On an input-heavy workload you need roughly a 26% cache-hit rate to take 25% off the input line — reachable for chatbots and agents that resend the same system prompt and history.
What real workloads cost on DeepSeek V4.1 Flash (batch)
These three workloads are the ones teams actually run on a budget-priced model — a $0.336/1M model is not bought for the same job as one ten times the price.
| Workload | Per request | Per month |
|---|---|---|
| High-volume classification — 200K requests/day (400 in / 20 out) Short output, huge volume: the input price dominates the bill. | $0.0001 | $309 |
| Small app — 1K requests/day (500 in / 150 out) The baseline most side projects actually run at. | $0.0001 | $3.19 |
| Long-context analysis — 200 runs/day (250K in / 4K out) Only possible on large-context models; input cost is nearly the whole bill. | $0.0293 | $176 |

› What does the high-volume classification workload cost on DeepSeek V4.1 Flash (batch)?
High-volume classification — 200K requests/day (400 in / 20 out) costs about $0.0001 per request and $309 per month on DeepSeek V4.1 Flash (batch). Short output, huge volume: the input price dominates the bill.
› What does it cost to fill DeepSeek V4.1 Flash (batch)'s 1M context window?
Sending 1M of input in a single request costs $0.1174 at $0.112 per million tokens — before any output. With prompt caching that same fill drops to about $0.0036 on repeat requests. This is why large context windows are cheap to advertise and expensive to actually use.
› Is DeepSeek V4.1 Flash (batch) worth the price?
DeepSeek V4.1 Flash (batch) is in the cheapest end of the market — cheaper than 85% of the models we track. At this price the question is not cost but capability: it is a good fit for classification, extraction, routing and bulk summarisation, and a poor fit for multi-step reasoning where a wrong answer costs more than the tokens saved.
