Author's Note: APIYI is the first to launch an SLA guarantee plan for Nano Banana Pro that provides credits for failed image generation requests. Stop wasting money on failed outputs—we'll issue credits per failed request for tool service providers with a monthly spend of $1,000+. This article details the eligibility criteria, credit mechanism, and technical validation standards.
As Google's flagship image generation model built on Gemini 3 Pro, Nano Banana Pro has gained widespread recognition for its 4K resolution, 94%+ text rendering accuracy, and professional-grade image quality. However, a long-standing issue for developers is that: Google still deducts quotas and charges for failed image generation requests. According to industry data, failure rates due to content safety policies can reach 20%-30%, meaning a significant portion of costs in high-volume scenarios is wasted on failed requests.
Starting February 1, 2026, APIYI is the first to launch the Nano Banana Pro SLA Guarantee Plan for Failed Image Generation—we will issue credits for failed requests, ensuring developers no longer have to pay for Google's over-sensitive moderation.
Core Value: Learn the eligibility criteria, credit mechanism, and technical validation standards for the APIYI Nano Banana Pro SLA guarantee in just 3 minutes to see if it fits your business needs.
Nano Banana Pro SLA Guarantee Core Rules
| Item | Details | Notes |
|---|---|---|
| Coverage | Failed Nano Banana Pro image generation requests | Includes text-only returns and empty responses |
| Credit Standard | Number of failures × $0.05 / Discount Coefficient | Converted based on actual recharge discount coefficient |
| Settlement Cycle | Monthly settlement, credits issued the following month | Based on exported logs from the previous month |
| Effective Date | Starting March 1, 2026 | Internal trial run began in February |
| Eligibility | Monthly spend of $1,000+ (all models) | Low threshold, includes consumption of all models |
SLA Validation Standards for Nano Banana Pro Failures
APIYI's SLA guarantee plan has clear technical validation standards for failed image generation, categorized into two types:
Type 1: Log Output Token < 1000
This occurs when Google returns text instead of an image. For example, the model replies, "I'm just a language model and can't help with that." This indicates the request was intercepted by content safety policies, but Google still consumed the quota and charged for it.
Type 2: Log Output Token is Empty
This is more direct—the model flatly refuses to generate the image, and the candidatesTokenCount in the API response is 0. The request is completely rejected, but the quota has already been consumed.
The commonality between these two types of failures is: The user did not receive any valuable image output, yet the quota and costs were incurred on Google's side. APIYI's SLA guarantee is specifically designed to issue credits for these scenarios.
🎯 Validation Note: Validation of failed image generation is based on APIYI platform logs. Developers can export the previous month's logs from the console, filter for eligible failed requests, and submit them to the APIYI team for verification and credit issuance.
Nano Banana Pro Failure Rate and SLA Cost Analysis
Why does Nano Banana Pro require an SLA? The core reason is that Google’s content safety policies tightened significantly in early 2026, leading to a noticeable spike in image generation failure rates.
Main Reasons for Nano Banana Pro Generation Failures
| Failure Reason | Trigger Scenario | Frequency | Controllable? |
|---|---|---|---|
| Intellectual Property | Celebrities, brand logos, copyrighted characters | High | Can be mitigated via prompts |
| IMAGE_SAFETY Filter | System misidentifies safe content as a violation | Med-High | Hard to control |
| Image Editing Limits | Face swapping, outfit changes, background replacement | Medium | Requires workflow adjustments |
| Over-moderation | Google officially admits filters are too cautious | Medium | Uncontrollable |
| blockReason OTHER | Vague rejections introduced in March 2026 | New | Uncontrollable |
Google has publicly acknowledged that Gemini’s image generation filters "became way more cautious than we intended," meaning even simple prompts like "a dog" or "a bowl of cereal" can trigger content safety policies. For service providers, it's difficult to fully control user inputs, and failure rates can hit 20%-30%.
Nano Banana Pro SLA Cost Recovery Analysis
Taking a monthly spend of $2,000 (approx. 40,000 requests at $0.05/request) as an example:
| Failure Rate | Failed Requests | Wasted Amount | SLA Rebate | Actual Savings |
|---|---|---|---|---|
| 10% | 4,000 | $200 | ~$174 (incl. discount) | Save $174/mo |
| 20% | 8,000 | $400 | ~$348 | Save $348/mo |
| 30% | 12,000 | $600 | ~$522 | Save $522/mo |
🎯 Cost Optimization: The Nano Banana Pro pricing on the APIYI (apiyi.com) platform is $0.05 per request. Combined with our SLA policy for failed generations, your actual effective cost per call is significantly lower. For high-volume service providers, this is currently the most reliable Nano Banana Pro API solution on the market.
How to Participate in the Nano Banana Pro SLA Guarantee
Eligibility for the Nano Banana Pro SLA Guarantee
To join the APIYI Nano Banana Pro "failed generation compensation" program, you'll need to meet the following criteria:
- Monthly Consumption Threshold: A minimum monthly spend of $1,000 (across any models on the platform). This threshold is relatively low—it's easily reachable for tool service providers handling tens of thousands of model invocations per month.
- Target Audience: Primarily aimed at tool service providers, as it's difficult to fully control the input content from end-users, making occasional generation failures an objective reality.
- Exclusions: Compensation will be denied for malicious requests or repeated submissions of identical or similar prohibited content.
- Effective Date: Officially effective starting March 1, 2026.
Steps to Claim Nano Banana Pro SLA Compensation
Step 1: Export your Nano Banana Pro invocation logs for the previous month from the APIYI dashboard.
Step 2: Filter for requests that meet the failure criteria (Token < 1000 or Token = 0).
Step 3: Submit the statistics to the APIYI team for verification. Once confirmed, compensation will be issued based on the following formula:
Compensation Amount = Number of Failures × $0.05 / Discount Coefficient
For example, if you have a 15% recharge bonus (a discount coefficient of 1.15) and 1,000 failed requests, the compensation amount would be:
1000 × $0.05 / 1.15 ≈ $43.48
The compensation will be credited directly to your account balance and can be used for any future model invocations.

FAQ
Q1: How is the refund calculated for failed image generation?
The refund formula is: Number of failed requests × $0.05 / discount coefficient. The discount coefficient depends on your top-up plan; for example, if you receive a 15% bonus on your top-up, the discount coefficient is 1.15. The refunded amount is credited directly to your account balance and can be used for any model invocation.
Q2: Can I participate if my monthly consumption is less than $1,000?
Currently, the SLA guarantee is available to users with a monthly consumption of $1,000 or more (across all models on the platform, not limited to Nano Banana Pro). This threshold is relatively low, and for small-scale testing or personal use, the probability and absolute cost of failed image generation are minimal. We recommend getting started via APIYI (apiyi.com), and you can apply to join the program at any time as your usage grows.
Q3: Are failures caused by malicious requests eligible for refunds?
No. The SLA guarantee explicitly excludes intentional malicious requests—such as repeatedly submitting the same or similar policy-violating content. Refunds are only provided for failures caused by non-subjective reasons, such as when Google's safety policy over-filters legitimate image generation requests.
Summary
Key highlights of the Nano Banana Pro SLA guarantee:
- Industry-first refund policy for failed generations: APIYI is the first to launch an SLA guarantee for Nano Banana Pro, offering balance refunds per failed request so you don't waste money on unsuccessful calls.
- Transparent refund mechanism: Logs are exportable, failures are traceable, and the formula is verifiable: Refund Amount = Number of failed requests × $0.05 / discount coefficient.
- Designed for tool providers: Available for those with $1,000+ in monthly consumption, making it ideal for tool services where user input is unpredictable and failure rates may be higher.
As Google's content safety policies continue to tighten in 2026, the failure rate for image generation has become a cost factor that cannot be ignored when using Nano Banana Pro. APIYI's SLA guarantee fundamentally solves the pain point of "paying for failures," ensuring developers only pay for successful image generation.
