GPT-5 Pricing Breakdown: Every Model, Every Tier, Every Cost
OpenAI's GPT-5 family now spans six models — from the ultra-cheap GPT-5 Nano at $0.05 per million input tokens to the powerhouse GPT-5.2 Pro at $21 per million input tokens. That's a 420x price difference within the same product family. Choosing the wrong tier could mean the difference between a $500/month API bill and a $50,000 one.
This guide breaks down every GPT-5 variant with real pricing data, cost calculations for common use cases, and clear recommendations for which model fits your workload. No hedging, no "it depends" — just numbers and decisions.
💡 Key Takeaway: Most teams should start with GPT-5 Mini ($0.25/$2 per million tokens) and only upgrade to GPT-5.2 when they hit a quality ceiling. The flagship models are 7-10x more expensive with marginal quality gains for typical tasks.
The Complete GPT-5 Model Lineup
Here's every model in the GPT-5 family with current API pricing:
| Model | Input (per 1M tokens) | Output (per 1M tokens) | Context Window | Max Output | Category |
|---|---|---|---|---|---|
| GPT-5 Nano | $0.05 | $0.40 | 128K | 16,384 | Budget |

Cost Per Request: What You Actually Pay
Per-million-token pricing is hard to reason about. Here's what each model costs for real tasks, assuming typical token counts:
Simple Tasks (500 input / 200 output tokens)
| Model | Cost Per Request | 10K Requests/Day | Monthly Cost |
|---|---|---|---|
| GPT-5 Nano | $0.000105 | $1.05 | $31.50 |
| GPT-5 Mini | $0.000525 | $5.25 | $157.50 |
| GPT-5 | $0.002625 | $26.25 | $787.50 |
| GPT-5.2 | $0.003675 | $36.75 | $1,102.50 |
| GPT-5.2 Pro | $0.044100 | $441.00 | $13,230.00 |
Complex Tasks (2,000 input / 1,000 output tokens)
| Model | Cost Per Request | 10K Requests/Day | Monthly Cost |
|---|---|---|---|
| GPT-5 Nano | $0.000500 | $5.00 | $150.00 |
| GPT-5 Mini | $0.002500 | $25.00 | $750.00 |
| GPT-5 | $0.012500 | $125.00 | $3,750.00 |
| GPT-5.2 | $0.017500 | $175.00 | $5,250.00 |
| GPT-5.2 Pro | $0.210000 | $2,100.00 | $63,000.00 |
📊 Quick Math: A SaaS product handling 10,000 complex requests per day pays $150/month with GPT-5 Nano or $63,000/month with GPT-5.2 Pro. That's not a rounding error — it's the difference between ramen profitability and needing Series A funding.
Long-Context Tasks (50,000 input / 2,000 output tokens)
Long-context workloads — document analysis, code review, RAG over large corpora — are where costs really diverge:
| Model | Cost Per Request | 1K Requests/Day | Monthly Cost |
|---|---|---|---|
| GPT-5 Nano | $0.003300 | $3.30 | $99.00 |
| GPT-5 Mini | $0.016500 | $16.50 | $495.00 |
| GPT-5 | $0.082500 | $82.50 | $2,475.00 |
| GPT-5.2 | $0.115500 | $115.50 | $3,465.00 |
| GPT-5.2 Pro | $1.386000 | $1,386.00 | $41,580.00 |
⚠️ Warning: Long-context requests are input-heavy, so the input price matters more than output price. GPT-5.2 Pro's $21/M input rate makes large document analysis extremely expensive. Consider chunking strategies or using GPT-5 Mini for initial passes.
GPT-5 Nano: The $0.05 Workhorse
GPT-5 Nano is OpenAI's cheapest model at $0.05 input / $0.40 output per million tokens. It's designed for high-volume, well-defined tasks where you need "good enough" quality at near-zero cost.
Best for:
- Classification and tagging
- Simple extraction (names, dates, amounts)
- Template-based text generation
- Routing requests to more expensive models
- Data validation and formatting
Not suitable for:
- Creative writing or nuanced analysis
- Complex reasoning chains
- Tasks requiring deep world knowledge
- Anything you'd show directly to a paying customer
GPT-5 Nano undercuts the older GPT-4o Mini by 3x on input, making it the best option for any task that doesn't require frontier intelligence. At scale, this adds up fast: a million daily classification requests costs roughly $1.50/day with Nano versus $4.50/day with GPT-4o Mini.
GPT-5 Mini: The Sweet Spot for Most Teams
At $0.25 input / $2.00 output per million tokens, GPT-5 Mini offers flagship-quality reasoning in a package that's 5x cheaper than GPT-5. For 80% of production workloads, this is the model you should be using.
Why GPT-5 Mini wins for most use cases:
- 500K context window covers nearly all document sizes
- 65K max output handles long-form generation
- Quality gap vs GPT-5 is marginal for structured tasks
- Cost is in the same ballpark as Gemini 2.5 Flash ($0.15/$0.60)
💡 Key Takeaway: GPT-5 Mini at $0.25/$2 sits in a competitive sweet spot. It's cheaper than Claude Haiku 4.5 ($1/$5) while matching it on most benchmarks. For teams committed to OpenAI's ecosystem, Mini is the default choice.
Cost comparison with competitors:
| Model | Input/M | Output/M | Provider |
|---|---|---|---|
| GPT-5 Mini | $0.25 | $2.00 | OpenAI |
| Gemini 2.5 Flash | $0.15 | $0.60 | |
| DeepSeek V3.2 | $0.28 | $0.42 | DeepSeek |
| Mistral Small 3.2 | $0.06 | $0.18 | Mistral |
| Claude Haiku 4.5 | $1.00 | $5.00 | Anthropic |
GPT-5 Mini's main disadvantage is output pricing — at $2/M, it's nearly 5x more expensive on output than DeepSeek V3.2 ($0.42/M). For generation-heavy tasks, DeepSeek or Mistral may be more economical. Use our cost calculator to compare for your specific token ratios.
GPT-5 vs GPT-5.1 vs GPT-5.2: Flagship Showdown
The three flagship GPT-5 models share 1M context windows and 131K max output, but differ in pricing and capability:
| Feature | GPT-5 | GPT-5.1 | GPT-5.2 |
|---|---|---|---|
| Input/M | $1.25 | $1.25 | $1.75 |
| Output/M | $10.00 | $10.00 | $14.00 |
| Release | Aug 2025 | Nov 2025 | Dec 2025 |
| Vision | ✅ | ✅ | ✅ |
| Audio | ❌ | ✅ | ✅ |
| Reasoning | Basic | Strong | Strongest |
The recommendation is straightforward: Use GPT-5.1 unless you specifically need GPT-5.2's enhanced coding and agentic capabilities. GPT-5.1 delivers 85-90% of GPT-5.2's performance at 71% of the input cost and 71% of the output cost. The original GPT-5 has no reason to exist in your stack anymore — GPT-5.1 is the same price with better performance.
✅ TL;DR: GPT-5.1 at $1.25/$10 is the best value flagship. Only upgrade to GPT-5.2 ($1.75/$14) if you're building coding tools or autonomous agents where the 10-15% quality improvement justifies a 40% cost increase.
GPT-5.2 Pro: When Money Is No Object
GPT-5.2 Pro is OpenAI's most expensive model at $21 input / $168 output per million tokens. It's a reasoning-specialized model that competes with o3-pro ($20/$80) but with significantly higher output costs.
[stat] $168/M GPT-5.2 Pro's output price — the most expensive per-token rate of any major API model
When GPT-5.2 Pro makes sense:
- Mathematical proofs and formal verification
- Complex multi-step research synthesis
- Legal or medical analysis where accuracy is critical
- Tasks where a single wrong answer costs more than $168
When it doesn't make sense (which is most of the time):
- Customer-facing chatbots (use GPT-5 Mini)
- Content generation (use GPT-5.1)
- Code completion (use GPT-5.2)
- Anything with more than 100 daily requests
Let's be concrete: if your application generates 500 tokens of output per request and you make 1,000 requests per day, GPT-5.2 Pro costs $84/day just in output tokens. GPT-5.2 handles the same load for $7/day. That's a 12x difference for a model that's marginally better on reasoning benchmarks.
⚠️ Warning: GPT-5.2 Pro's output pricing ($168/M) is more than double o3-pro's ($80/M). If you need OpenAI's best reasoning, compare both — o3-pro may deliver similar quality at lower output costs depending on your task profile.
OpenAI's Reasoning Models: o3 and o4-Mini
OpenAI also offers dedicated reasoning models that overlap with the GPT-5 family:
| Model | Input/M | Output/M | Best For |
|---|---|---|---|
| o4-mini | $1.10 | $4.40 | Efficient reasoning |
| o3 | $2.00 | $8.00 | General reasoning |
| o3-pro | $20.00 | $80.00 | Maximum reasoning |
| o1 | $15.00 | $60.00 | Legacy reasoning |
How to choose between GPT-5.2 and o3:
- GPT-5.2 ($1.75/$14) is better for general tasks with some reasoning
- o3 ($2/$8) is better when reasoning is the primary requirement — cheaper output
- o4-mini ($1.10/$4.40) is the budget reasoning pick — cheaper than GPT-5 Mini on output
For reasoning-heavy workloads, o4-mini at $1.10/$4.40 actually undercuts GPT-5 Mini ($0.25/$2) when output tokens exceed input tokens by 2:1 or more. Check our token calculator to model your specific ratio.
Cost Optimization Strategies for GPT-5
1. Use Model Routing
Don't send every request to the same model. Build a routing layer:
- Simple queries → GPT-5 Nano ($0.05/$0.40)
- Standard tasks → GPT-5 Mini ($0.25/$2.00), or GPT-5.4 mini when you need stronger coding and tool use
- Complex analysis → GPT-5.1 ($1.25/$10.00)
- Critical reasoning → GPT-5.2 Pro ($21/$168) — sparingly
A well-designed router can reduce costs by 60-80% compared to sending everything to a flagship model. Read our guide on AI API cost optimization strategies for implementation details.
2. Leverage the Batch API
OpenAI's Batch API offers 50% off on all models for non-time-sensitive requests. That brings GPT-5.2 down to roughly $0.875/$7 per million tokens — cheaper than standard GPT-5 pricing.
| Model | Standard Input/M | Batch Input/M | Savings |
|---|---|---|---|
| GPT-5 Nano | $0.05 | $0.025 | 50% |
| GPT-5 Mini | $0.25 | $0.125 | 50% |
| GPT-5.2 | $1.75 | $0.875 | 50% |
If your workload can tolerate 24-hour turnaround, the Batch API should be your default. See our OpenAI Batch API guide for setup instructions.
📊 Quick Math: An analytics pipeline processing 1M tokens of input daily through GPT-5.2 saves $0.875/day or $26.25/month per million tokens just by switching to batch. At 100M tokens/day, that's $2,625/month saved.
3. Prompt Compression and Caching
OpenAI's prompt caching automatically discounts repeated prefixes. For applications with system prompts or shared context:
- Cache hits cost 50% less on input tokens
- Long system prompts (1,000+ tokens) benefit most
- Combine with GPT-5 Mini for maximum savings
4. Consider Alternatives for Specific Tasks
OpenAI isn't always the cheapest option. For specific workloads:
- High-volume classification: Mistral Small 3.2 at $0.06/$0.18 beats GPT-5 Nano
- Long-form generation: DeepSeek V3.2 at $0.28/$0.42 has dirt-cheap output
- Balanced performance: Gemini 2.5 Flash at $0.15/$0.60 undercuts GPT-5 Mini
See our cheapest AI APIs guide for the full comparison.
