1️⃣ 480p: ¥0.05/second, supports 1–15 seconds 2️⃣ 768p: ¥0.07/second, supports 1–15 seconds 3️⃣ 1080p: ¥0.15/second, supports 1–10 seconds ⚠️ Supports reference images for video generation (up to 9 images) and reference audio (up to 3 files). Frequently Asked Questions: 1. How is video generation billed? Billing is based on resolution and duration. See the model list for details. 2. How long does video generation take? It depends on the configured duration and reference materials. Generation usually takes around 4–12 minutes and may take longer during peak hours. Thank you for your patience. 3. What should I do if the result is unsatisfactory? Video generation requires professional prompts. Overly brief prompts rarely produce high-quality results. Please improve your prompt and try again. 4. How long are generated files retained? Images and videos are retained for 2 hours. 5. Are credits refunded for failed or policy-violating requests? Yes. 6. When will ComfyUI be updated? We will post an announcement after the update. Thank you for your patience.

Price and API usage remain unchanged nano-banana-fast remains ¥0.022, and its API usage is unchanged. Integrated users do not need to modify their code. 2. New model price nano-banana-2-lite: ¥0.022
📢 Second price adjustment for Banana CL and VIP channels We apologize for adjusting prices again. Recent risk-control measures have sharply increased costs. Despite a small adjustment a few days ago, these services are still operating at a loss. To maintain stable service, we must make a second price adjustment for the following models: nano-banana-pro-cl: 10,000 credits | ¥0.50 nano-banana-pro-vip: 10,000 credits | ¥0.50 nano-banana-pro-4k-vip: 18,000 credits | ¥0.90 nano-banana-2-cl: 6,000 credits | ¥0.30 nano-banana-2-2k-cl: 9,000 credits | ¥0.45 nano-banana-2-4k-cl: 13,000 credits | ¥0.65 ⚠️ Notes: 1. These changes will take effect at 12:00 PM on Monday. 2. If costs fall, we will lower prices accordingly. 3. CL/VIP channels are intended for enterprise users with sufficient budgets and very high requirements for generation speed and stability. 4. nano-banana-2 and nano-banana-pro are not affected. We appreciate your understanding and support.
CL channel model resolutions and prices will change at 7:00 PM tonight. Due to increased channel costs, supported resolutions and prices for CL models will be adjusted as follows: I. nano-banana-pro-cl Supported resolution: 1K only (2K and 4K removed) Credits: 6,000 Price: ¥0.30 💡 For 2K or 4K, use one of these upgraded versions: 1–2K: nano-banana-pro-vip (10,000 credits | ¥0.50) 4K: nano-banana-pro-4k-vip (16,000 credits | ¥0.80) II. nano-banana-2-cl Supported resolution: 1K only (2K removed) Credits: 1,600 Price: ¥0.08 💡 For 2K or 4K, use an upgraded version: New 2K version: nano-banana-2-2k-cl (4,000 credits | ¥0.20) 4K version price increase: nano-banana-2-4k-cl (6,000 credits | ¥0.30) Important: 1. These changes will take effect at 7:00 PM tonight. 2. nano-banana-2 and nano-banana-pro are not affected. 3. Failed CL and VIP Banana channel requests are refunded; policy-violating requests are not refunded.

Existing integrations do not need to switch. The new documentation adds a unified endpoint (https://{base_url}/v1/api/generate) that can call every model available through Grsai API. In the old documentation, Banana and GPT models use different endpoints. The new endpoint is more convenient, so choose whichever option best meets your needs. Important: Do not mix parameters from the old and new documentation.
Frequently Asked Questions: 1. Can I continue using the old documentation? Yes. It will remain valid permanently. 2. What is the difference between the old and new documentation? The new documentation is more beginner-friendly, includes stable one-click copyable examples that can be sent to AI assistants, uses one endpoint for all models, fine-tunes parameters, and provides examples in multiple programming languages.
Frequent OpenAI risk-control measures have continued to increase the operating cost of gpt-image-2-vip. After careful consideration, we have decided to adjust its price: gpt-image-2-vip: ¥0.045 → ¥0.065 We apologize for any inconvenience and appreciate your continued support.
New model: gpt-image-2-vip Starting price: ¥0.045/image Available resolutions: 1K, 2K, 4K Available quality levels: low, medium, high; default: auto Custom pixel dimensions: see the official documentation for details
Frequently Asked Questions: 1. Resolution and pixel-dimension options are being added to the batch generation tool (image.grsai.ai). 2. The following OpenAI-compatible endpoints are supported: /v1/chat/completions and /v1/images/generations.
Multiple network proxy providers went down simultaneously at 11:10 AM, making several models unavailable. Service was restored after two hours. Affected models: nano-banana nano-banana-fast nano-banana-pro nano-banana-2 gpt-image-2
The OpenAI-compatible completions API now supports gpt-image-2, allowing image generation directly through the chat endpoint.
