Key Takeaway (TL;DR): GPT Image 2.5 makes state-of-the-art image synthesis dramatically more accessible. On PoYo, Flare and Sunburst share identical tier pricing:
- Ultra-Low Entry Tier: 1K low costs just 1.31 credits ($0.00655 / image);
- Standard Production Tier: 1K medium costs 2.95 credits ($0.01475 / image);
- Ultra-High Print Tier: Available up to max 4K (~$0.448 / image). Unlike OpenAI's native variable token billing, PoYo provides deterministic per-image credit pricing (1 credit = $0.005), enabling predictable project budgeting.

1. Two Pricing Models: Native Token vs Deterministic Credits
1. OpenAI Native API: Dynamic Token Billing
Official Flare and Sunburst endpoints bill based on dynamic token consumption:
| Token Category | Native Rate per 1M Tokens | Description |
|---|---|---|
| Text Input | $5.00 | Prompt instructions |
| Cached Text Input | $1.25 | Prompt prefix cache hits |
| Image Input | $8.00 | Reference images & editing source files |
| Cached Image Input | $2.00 | Cached image context |
| Image Output | $30.00 | Generated image output tokens |
The Challenge: Variable output tokens make it difficult for engineering teams to accurately forecast billing before firing API calls.
2. PoYo Platform: Predictable Tiered Credits
PoYo eliminates unpredictable billing surprises:
- Exchange Baseline: 1 credit = $0.005 USD;
- Deterministic Pricing: Fixed rates per [Quality Tier + Resolution Tier], with zero prompt-length surcharges.
2. Complete 15-Tier Quality & Resolution Matrix
Both gpt-image-2.5-flare and gpt-image-2.5-sunburst map to these 15 pricing tiers:
| Quality Tier | Resolution Tier | Credits per Generation | Cost in USD ($0.005/credit) | Recommended Workload |
|---|---|---|---|---|
| low | 1K | 1.31 | $0.00655 | Rapid prototyping, exploratory brainstorming |
| low | 2K | 2.65 | $0.01325 | Quick layout validation |
| low | 4K | 2.47 | $0.01235 | Large-format framing tests |
| medium (Standard) | 1K | 2.95 | $0.01475 | Social media, e-commerce catalog, blog assets |
| medium | 2K | 5.99 | $0.02995 | Web banners, video storyboards |
| medium | 4K | 5.81 | $0.02905 | High-resolution hero displays |
| high | 1K | 11.78 | $0.05890 | Transparent sprite sheets, game art |
| high | 2K | 23.94 | $0.11970 | Commercial product rendering |
| high | 4K | 22.39 | $0.11195 | Ultra-sharp advertising creatives |
| xhigh | 1K | 20.93 | $0.10465 | Micro-detailed artwork |
| xhigh | 2K | 42.55 | $0.21275 | Commercial photography portfolios |
| xhigh | 4K | 39.78 | $0.19890 | Large-format display prints |
| max | 1K | 47.11 | $0.23555 | Maximum texture rendering |
| max | 2K | 95.74 | $0.47870 | Publishing-grade cover art |
| max | 4K | 89.51 | $0.44755 | Gallery and billboard print deliverables |
Why are some 4K tiers slightly lower than 2K? PoYo's current backend routing utilizes optimized tiled inference pathways for select high-resolution tiers.
3. Practical Production Budget Models
| Production Scenario | Configuration | Monthly Volume | Total Credits | Monthly Budget (USD) |
|---|---|---|---|---|
| Social Content Pipeline | medium 1K | 100 images | 295 credits | $1.48 |
| E-Commerce SKU Catalog | medium 1K | 1,000 images | 2,950 credits | $14.75 |
| Indie Game Sprite Assets | high 1K (transparent) | 100 sheets | 1,178 credits | $5.89 |
| Commercial Banner Production | high 2K | 100 images | 2,394 credits | $11.97 |
| Iterative Multi-Turn Editing | medium 2K (10 turns) | 5 chains (50 runs) | 299.5 credits | $1.50 |
| Large-Format Print Campaign | max 4K | 20 prints | 1,790.2 credits | $8.95 |
4. Engineering Optimization: Cost per Accepted Asset
True ROI is governed by the total cost to produce a finalized asset, not just single-run pricing:
$$\text{Cost per Accepted Asset} = \frac{\text{Total Generation Costs} + \text{Editing Costs} + \text{Human Retouching Hours}}{\text{Accepted Final Assets}}$$
Cost Reduction Best Practices:
- Progressive Upscaling:
- Never start with
max 4K($0.45/run) for unvetted prompts; - Start with
low 1K($0.0065/run) to dial in prompt geometry and lighting; - Upscale to
mediumorhighonce composition is confirmed.
- Never start with
- Combine Flare and Sunburst:
- Use Flare for bulk generation and conceptual drafting;
- Switch to Sunburst exclusively for localized surgical edits.
- Save Intermediate Checkpoints:
- Always save intermediate image URLs during multi-turn revisions. If turn 5 fails, fork from turn 3 rather than restarting the entire chain. See our 10-Step Editing Report.
5. Tracking Task Costs via API
Query task status and monitor exact credit deductions via PoYo's status endpoint:
GET https://api.poyo.ai/api/generate/status/{task_id}
Authorization: Bearer YOUR_POYO_API_KEY
The returned credits_amount reflects the exact deduction for your task records.
Frequently Asked Questions (FAQ)
Does 1 credit equal 1 image?
No. 1 credit represents $0.005 USD. Generation tasks consume decimal fractions or multiples of credits depending on chosen quality and resolution tiers.
Are reference images billed extra?
Not on PoYo. Generations using reference images are billed at the standard tier rate, protecting you from unpredictable input-token spikes.
How much cheaper is 2.5 compared to Image 2?
65.2% cheaper on standard tiers. A 1K medium image dropped from 8.48 credits ($0.0424) on GPT Image 2 down to 2.95 credits ($0.01475) on GPT Image 2.5.
