Where GPT-5.4 Pro (batch) sits on price
At $90.00 per million output tokens, GPT-5.4 Pro (batch) is a frontier tier model — 40.0× the median output price of $2.25, which puts it in the most expensive 10% of everything we track. It sits 87th cheapest of the 93 OpenAI models we track. Output costs 6.0× more than input here, so anything that makes the model write less — tighter instructions, structured output, lower max_tokens — moves the bill more than trimming the prompt.
What real workloads cost on GPT-5.4 Pro (batch)
These three workloads are the ones teams actually run on a frontier-priced model — a $90.00/1M model is not bought for the same job as one ten times the price.
| Workload | Per request | Per month |
|---|---|---|
| Small app — 1K requests/day (500 in / 150 out) The baseline most side projects actually run at. | $0.021 | $630 |
| Coding agent — 300 sessions/day (60K in / 12K out) Multi-step loops re-read the same files; caching matters more than raw price. | $1.98 | $17820 |
| Support chatbot — 500 conversations/day (5K in / 1.4K out) Conversation history re-sent each turn — the classic prompt-caching win. | $0.201 | $3015 |
Model your exact traffic in the API cost calculator — it preloads GPT-5.4 Pro (batch) with caching and batch options.

GPT-5.4 Pro (batch) vs Claude Opus 4.1
The closest-priced alternative from another vendor is Claude Opus 4.1 (Anthropic) — 17% cheaper on output, with identical input pricing. 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-5.4 Pro (batch) API cost?
GPT-5.4 Pro (batch) costs $15.00 per million input tokens and $90.00 per million output tokens and no discounted cached-input tier. That works out to roughly 11,111 output tokens per dollar.
› What does the small app workload cost on GPT-5.4 Pro (batch)?
Small app — 1K requests/day (500 in / 150 out) costs about $0.021 per request and $630 per month on GPT-5.4 Pro (batch). The baseline most side projects actually run at.
› What does it cost to fill GPT-5.4 Pro (batch)'s 1.1M context window?
Sending 1.1M of input in a single request costs $15.75 at $15.00 per million tokens — before any output. There is no cached-input tier on this model, so every repeat of that context is billed at full price. This is why large context windows are cheap to advertise and expensive to actually use.
› Is GPT-5.4 Pro (batch) worth the price?
GPT-5.4 Pro (batch) is priced in the top bracket, at $90.00 per million output tokens. It only pays off where an error is expensive — production code, legal and medical drafting, agents that take real actions. For anything routine, GPT-5.2 Pro (batch) at $84.00 does the same job for a fraction of the bill.
