GPT-5.4 mini API Pricing: The Sweet Spot at $0.75/M Tokens

Q: How much does GPT-5.4 mini cost?

GPT-5.4 mini costs $0.75 per million input tokens and $4.50 per million output tokens. It's 70% cheaper than GPT-5.4 ($2.50/$15) on both input and output, making it the best value in the GPT-5.4 family for most workloads.

Q: What is the context window of GPT-5.4 mini?

GPT-5.4 mini has a 400K token context window — the same as GPT-5.4 and GPT-5.4 nano. This is sufficient for most document analysis, code review, and multi-turn conversation workloads.

Q: GPT-5.4 mini vs GPT-5.4 — is the full model worth 3.3x more?

For most workloads, no. GPT-5.4 mini ($0.75/$4.50) delivers 70% of GPT-5.4's quality at 30% of the cost. Use full GPT-5.4 ($2.50/$15) only when you need maximum reasoning capability — complex code generation, nuanced analysis, or multi-step agentic workflows.

Q: What can GPT-5.4 mini be used for?

GPT-5.4 mini excels at customer-facing chatbots, content generation, code assistance, document summarization, and API backends. It's the default choice when you need quality outputs but can't justify GPT-5.4's premium pricing. For simpler tasks, GPT-5.4 nano is cheaper.

GPT-5.4 mini delivers 70% of GPT-5.4's quality at 30% of the cost — the best balance of capability and price for production workloads.

GPT-5.4 mini Pricing Breakdown

At $0.75 per million input tokens and $4.50 per million output tokens, GPT-5.4 mini is 70% cheaper than GPT-5.4 while maintaining strong quality. Here's how costs scale:

Monthly Volume	Input Cost	Output Cost	Total Cost
1M tokens	$0.75	$4.50	$5.25
10M tokens	$7.50	$45.00	$52.50
100M tokens	$75.00	$450.00	$525.00
1B tokens	$750.00	$4,500.00	$5,250.00

At 100M tokens/month, GPT-5.4 mini costs $525. The same volume on full GPT-5.4 would cost $1,800, and on Claude Sonnet 5 it would cost $900+.

How GPT-5.4 mini Compares to Other Models

Model	Input $/M	Output $/M	Context	Quality Tier	Provider
GPT-5.4 nano	$0.20	$1.25	400K	Good	OpenAI
Claude Haiku 4.5	$1.00	$5.00	200K	Good	Anthropic
GPT-5.4 mini	$0.75	$4.50	400K	Strong	OpenAI
Claude Sonnet 5	$2.00	$10.00	1M	Excellent	Anthropic
GPT-5.4	$2.50	$15.00	400K	Excellent	OpenAI
Claude Opus 5	$5.00	$25.00	1M	Frontier	Anthropic

GPT-5.4 mini sits in a unique position: cheaper than Claude Haiku 4.5 on output, with better reasoning quality and a larger context window. It's 2.7x cheaper than Claude Sonnet 5 on input for workloads that need strong but not frontier-level intelligence.

GPT-5.4 Family: nano vs mini vs full vs Pro

Model	Input $/M	Output $/M	Context	Best For
GPT-5.4 nano	$0.20	$1.25	400K	Classification, extraction, high-volume simple tasks
GPT-5.4 mini	$0.75	$4.50	400K	Chatbots, content, code, most production workloads
GPT-5.4	$2.50	$15.00	400K	Complex reasoning, agentic workflows, frontier tasks
GPT-5.4 Pro	$30.00	$180.00	400K	Maximum capability, research, critical analysis

The decision is straightforward: Start with GPT-5.4 mini. Only drop to nano if you need to optimize costs on simple tasks, or upgrade to full GPT-5.4 if mini's quality isn't sufficient for your specific workload.

When to Use GPT-5.4 mini

💬 Customer-Facing Chatbots

Support bots, sales assistants, and conversational agents. Quality outputs that represent your brand well, at a fraction of GPT-5.4's cost.

When NOT to Use GPT-5.4 mini

GPT-5.4 mini is the best default, but there are better choices for specific needs:

Simple, high-volume tasks: Classification, extraction, moderation → use GPT-5.4 nano ($0.20/$1.25) for 3.75x savings
Complex agentic workflows: Multi-step planning, autonomous tool use → use GPT-5.4 ($2.50/$15) or Claude Sonnet 5 ($2/$10)
Maximum reasoning: Research, critical analysis, frontier tasks → use Claude Opus 5 ($5/$25) or GPT-5.4 Pro ($30/$180)
Vision input: Image analysis → use Gemini 3.1 Flash ($0.50/$3.00) or Qwen 3.7 Flash ($0.03/$0.13)
1M+ context: Very large documents → use Claude Sonnet 5 (1M) or GPT-4.1 mini ($0.40/$1.60, 1M)

Real-World Cost Scenario

Let's say you're building a customer support chatbot that handles 50,000 conversations per month, with an average of 2,000 input tokens and 800 output tokens per conversation:

Model	Monthly Input	Monthly Output	Total
GPT-5.4 nano	$20	$50	$70
GPT-5.4 mini	$75	$180	$255
Claude Haiku 4.5	$100	$200	$300
Claude Sonnet 5	$200	$400	$600
GPT-5.4	$250	$600	$850

GPT-5.4 mini costs $255/month for 50K support conversations — 15% cheaper than Claude Haiku 4.5 and 3.3x cheaper than full GPT-5.4. For customer-facing applications, the quality difference vs nano is usually worth the 3.6x price increase.
