Where GPT-4.1 Mini (batch) sits on price

At $0.8 per million output tokens, GPT-4.1 Mini (batch) is a mid tier model — 2.8× cheaper than the median output price of $2.25, which puts it cheaper than 74% and pricier than 26% of the models we track. It sits 15th cheapest of the 93 OpenAI models we track. Output costs 4.0× input, the usual spread — trim both, starting with the answer length.

Cached input is 75% cheaper. On an input-heavy workload you need roughly a 33% 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 GPT-4.1 Mini (batch)

These three workloads are the ones teams actually run on a mid-priced model — a $0.8/1M 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. $0.0021 $31.80
Document pipeline — 10K docs/day (3K in / 500 out) Batch-friendly: no user waiting, so a ~50% batch discount usually applies. $0.001 $300
Long-context analysis — 200 runs/day (250K in / 4K out) Only possible on large-context models; input cost is nearly the whole bill. $0.0532 $319

GPT-4.1 Mini (batch) vs Qwen3 Coder Next

The closest-priced alternative from another vendor is Qwen3 Coder Next (Alibaba (Qwen)) — priced within a rounding error on output, with $0.08 less per million input tokens. When two models land this close on price, the decision is quality on your own workload, not the price sheet: run 50 real requests through both and compare.

Frequently asked questions

How much does the GPT-4.1 Mini (batch) API cost?

GPT-4.1 Mini (batch) costs $0.2 per million input tokens and $0.8 per million output tokens, with cached input at $0.05 per million (75% cheaper). That works out to roughly 1,250,000 output tokens per dollar.

What does the support chatbot workload cost on GPT-4.1 Mini (batch)?

Support chatbot — 500 conversations/day (5K in / 1.4K out) costs about $0.0021 per request and $31.80 per month on GPT-4.1 Mini (batch). Conversation history re-sent each turn — the classic prompt-caching win.

What does it cost to fill GPT-4.1 Mini (batch)'s 1M context window?

Sending 1M of input in a single request costs $0.2095 at $0.2 per million tokens — before any output. With prompt caching that same fill drops to about $0.0524 on repeat requests. This is why large context windows are cheap to advertise and expensive to actually use.

Is GPT-4.1 Mini (batch) worth the price?

GPT-4.1 Mini (batch) sits in the middle of the market (15 of 93 by price within OpenAI). 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.
