GPT-5.4 API Cost: Complete Pricing Guide 2026
GPT-5.4 is OpenAI's mid-tier workhorse, priced at $2.50/$15.00 per 1M tokens (input/output). It sits between the budget GPT-5 ($1.25/$10.00) and the premium GPT-5.5 ($5.00/$30.00), offering a 400K token context window that handles most production workloads without the flagship price tag.
This guide breaks down GPT-5.4's real-world costs, compares it to every major alternative, and helps you decide when it's the right choice for your workload.
OpenAI GPT-5.4 Pricing at a Glance
| Model | Input (per 1M) | Output (per 1M) | Context | Tier |
|---|---|---|---|---|
| GPT-5.4 | $2.50 | $15.00 | 400K | Mid |
| GPT-5.4 mini | $0.75 | $4.50 | 400K | Budget |
| GPT-5.4 nano | $0.20 | $1.25 | 400K | Budget |
| GPT-5.4 Pro | $30.00 | $180.00 | 400K | Ultra-Premium |
| GPT-5 | $1.25 | $10.00 | 272K | Mid-Premium |
| GPT-5.5 | $5.00 | $30.00 | 1M | Premium |
| GPT-4o | $2.50 | $10.00 | 128K | Mid |
Key insight: GPT-5.4 matches GPT-4o's input price ($2.50) but costs 50% more on output ($15.00 vs $10.00). However, you get 3x the context window (400K vs 128K) and significantly better reasoning. The GPT-5.4 family also includes mini ($0.75/$4.50) and nano ($0.20/$1.25) variants for budget-conscious workloads — all with the same 400K context.

How GPT-5.4 stacks up:
- vs Claude Sonnet 5: GPT-5.4 is 17% cheaper on input ($2.50 vs $3.00) with identical output pricing. Claude wins on context (1M vs 400K). For workloads under 400K tokens, it's a wash — choose based on quality and ecosystem.
- vs Gemini 3.1 Pro: Gemini is cheaper across the board ($2.00/$12.00) with a larger context window. GPT-5.4 typically produces better code generation and structured output. Choose Gemini for cost, GPT-5.4 for quality on complex tasks.
- vs DeepSeek V4 Pro: DeepSeek is 5-17x cheaper. If your workload doesn't need GPT-5.4's reasoning depth, DeepSeek is the clear cost winner. GPT-5.4 wins on complex reasoning, code review, and nuanced instruction following.
- vs Grok 4.3: Grok is cheaper ($1.25/$2.50) with a larger context window. GPT-5.4 has stronger enterprise ecosystem support and more mature tooling. Grok is the value pick; GPT-5.4 is the safe choice.
Real-World GPT-5.4 Cost Scenarios
Scenario 1: Production Chatbot (5,000 messages/day)
Average: 800 input tokens, 400 output tokens per message. 30 days/month.
Monthly Chatbot Cost
Verdict: For chatbot workloads, GPT-5.4 costs the same as Claude Sonnet 5. If quality is sufficient, GPT-5.4 mini saves 70% at $378/mo. DeepSeek V4 Pro is 8x cheaper but may not match GPT-5.4's reasoning quality.
Scenario 2: Code Review (500 requests/day)
Average: 4,000 input tokens, 1,500 output tokens per request. 30 days/month.
Monthly Code Review Cost
Verdict: For code review, GPT-5.4 is 6% cheaper than Claude Sonnet 5 ($487.50 vs $517.50) thanks to lower input pricing. Gemini 3.1 Pro is 26% cheaper. If you need GPT-5.4's code quality, it's competitively priced for this workload.
Scenario 3: Document Analysis (200 requests/day)
Average: 15,000 input tokens, 2,000 output tokens per request. 30 days/month.
Monthly Document Analysis Cost
Verdict: For input-heavy document analysis, GPT-5.4's $2.50 input price makes it 10% cheaper than Claude Sonnet 5. But Gemini 3.1 Pro ($2.00 input) is 20% cheaper than GPT-5.4 for this workload. DeepSeek V4 Pro dominates on pure cost.
GPT-5.4 Family: mini, nano, and Pro
The GPT-5.4 family shares the same 400K context window but spans a wide cost range:
| Variant | Input | Output | Best For |
|---|---|---|---|
| GPT-5.4 | $2.50 | $15.00 | General-purpose production workloads |
| GPT-5.4 mini | $0.75 | $4.50 | High-volume, cost-sensitive workloads |
| GPT-5.4 nano | $0.20 | $1.25 | Classification, extraction, simple tasks |
| GPT-5.4 Pro | $30.00 | $180.00 | Maximum quality, complex reasoning |
When to use each:
- GPT-5.4 nano ($0.20/$1.25): Use for classification, sentiment analysis, data extraction, and simple Q&A. It's the cheapest option in the family — 12.5x cheaper on input than full GPT-5.4.
- GPT-5.4 mini ($0.75/$4.50): The sweet spot for most workloads. It's 70% cheaper than GPT-5.4 while maintaining strong quality for chatbots, content generation, and code assistance.
- GPT-5.4 ($2.50/$15.00): Use when you need the full reasoning capability for complex tasks — multi-step analysis, nuanced code review, or detailed content creation.
- GPT-5.4 Pro ($30.00/$180.00): Only for tasks where quality is paramount and cost is no object. 12x the input cost of standard GPT-5.4.

FAQ
How much does GPT-5.4 cost per request?
A typical request (1,500 input tokens, 500 output tokens) costs $0.01125 — about 1.1 cents. That breaks down to $0.00375 for input and $0.0075 for output.
Is GPT-5.4 worth the price over GPT-5?
GPT-5.4 costs 2x on input and 1.5x on output compared to GPT-5. You get a larger context window (400K vs 272K) and slightly better reasoning. For most workloads, GPT-5 is the better value. Choose GPT-5.4 when you specifically need the extra context or marginally better quality.
Can I use GPT-5.4 for function calling?
Yes. GPT-5.4 supports OpenAI's function calling and tool use APIs. It's one of the best models for structured output and agentic workflows.
How does GPT-5.4 compare to Claude Sonnet 5 for coding?
Both are excellent for coding. Claude Sonnet 5 has an edge on complex multi-file refactoring and large codebase analysis (1M context). GPT-5.4 is competitive on code generation and faster for iterative development. Cost is nearly identical ($2.50/$15.00 vs $3.00/$15.00).
What's the cheapest way to use GPT-5.4?
Use GPT-5.4 nano ($0.20/$1.25) for simple tasks, or GPT-5.4 mini ($0.75/$4.50) for general workloads. Both share the 400K context window at a fraction of the cost. Only use full GPT-5.4 when you need its maximum reasoning capability.
