Gpt-4o Mini Pricing
Gpt-4o mini pricing: 90% cheaper than full GPT-4o. Released July 2024.
Mini is cheap and fast. Good for classification, summarization, simple reasoning. Full GPT-4o for complex stuff.
Performance gap is small for many tasks, which is why mini took off.
OpenAI Pricing
GPT-4o Mini Rates (as of March 2026):
- Input: $0.15 per 1M tokens
- Output: $0.60 per 1M tokens
GPT-4o Full Rates:
- Input: $2.50 per 1M tokens
- Output: $10.00 per 1M tokens
GPT-4.1 Rates (faster option):
- Input: $2.00 per 1M tokens
- Output: $8.00 per 1M tokens
Real-world example: Processing 1M tokens input, generating 100K tokens output:
Mini: (1M × $0.00015) + (100K × $0.0060) = $150 + $600 = $750 Full GPT-4o: (1M × $0.0025) + (100K × $0.10) = $2,500 + $1,000 = $3,500
Mini saves $2,750 on this workload. Scale matters. For 10M input tokens monthly, mini saves $27K annually.
Mini includes vision capabilities matching full GPT-4o. Rate applies to both text and image inputs.
Alternative Providers
Anthropic Claude Sonnet 4.6:
- Input: $3.00 per 1M tokens
- Output: $15.00 per 1M tokens
No "mini" variant. Sonnet positioned as balanced option (faster than Opus, cheaper than full).
For 1M input + 100K output: $3,000 + $1,500 = $4,500. Costlier than GPT-4o mini but cheaper than GPT-4o full.
Anthropic Claude Opus 4.6:
- Input: $5.00 per 1M tokens
- Output: $25.00 per 1M tokens
Most capable Anthropic model. Premium pricing reflects performance.
Google Gemini 2.5 Pro:
- Input: $1.25 per 1M tokens
- Output: $10.00 per 1M tokens
No mini variant. Gemini 2.5 Flash ($0.30/$2.50) serves as the budget option. Google emphasizes long context (1M tokens).
See LLM API pricing comparison for full details.
Cost Comparison
Monthly cost for typical chatbot app (10M input tokens, 1M output tokens):
| Provider | Input Cost | Output Cost | Total |
|---|---|---|---|
| GPT-4o Mini | $1,500 | $600 | $2,100 |
| GPT-4.1 | $20,000 | $8,000 | $28,000 |
| GPT-4o Full | $25,000 | $10,000 | $35,000 |
| Sonnet 4.6 | $30,000 | $15,000 | $45,000 |
| Opus 4.6 | $50,000 | $25,000 | $75,000 |
For high-volume, latency-insensitive apps, mini wins decisively. For low-volume, performance-critical apps, full GPT-4o justified despite cost.
Performance Tradeoffs
GPT-4o Mini Strengths:
- 90% faster than full GPT-4o
- 95% accuracy on classification tasks
- Sufficient for chatbots, summarization, basic QA
- Vision capabilities match full model
GPT-4o Mini Weaknesses:
- Struggles with complex reasoning (math, coding)
- Lower accuracy on ambiguous queries (85% vs 95%)
- Smaller context window (128K vs 128K for GPT-4o full)
- Less reliable for multi-step instructions
Testing recommendation: Run A/B test on actual workload. Compare accuracy. Most teams find mini acceptable for 70% of use cases.
See LoRA fine-tuning for ways to improve mini's reasoning through adaptation.
When to Use Mini
Use Mini for:
- Classification (sentiment, category, intent)
- Summarization
- Content moderation
- Simple QA systems
- First-pass document processing
- High-volume operations where cost dominates
- Edge cases requiring GPT-4 compatibility
Use Full GPT-4o for:
- Complex reasoning (multi-step logic)
- Code generation and debugging
- Creative writing
- Complex research queries
- Cases where accuracy must be highest
- Low-volume, high-stakes scenarios
Hybrid approach (recommended): Route requests to mini first. On low-confidence outputs, escalate to full GPT-4o. Saves 80% of costs while maintaining quality.
FAQ
Can mini replace full GPT-4o? For 70% of use cases yes. For complex reasoning and creative tasks, no. Run benchmarks on actual data.
What's the token limit per request? Mini: 128K context window. Full GPT-4o: 128K. Most requests fit mini limits.
How does mini compare to GPT-3.5? Mini is significantly better. 3.5 was deprecated. Mini is the budget option for GPT-4 era.
Should I use mini for production? Yes, if benchmarks show acceptable accuracy. Popular in production (Anthropic reports 40% of requests route to cheaper models).
Is vision pricing the same for mini? Yes. $0.15/$0.60 rates apply to text and image inputs equally.
Can I fine-tune mini? No. Fine-tuning limited to certain models (GPT-4o full). Use LoRA adapters on local models instead.
