Getting started
The basics, plans, and how credits work.
Do I need special software?
No. HummingBytes runs in your web browser. Choose a model, write or reuse a prompt, and configure the available settings. You do not need a local GPU.
Is there a free trial?
There is no free trial. Starter is the lowest-priced current public subscription. Compare the current plans on the pricing page before subscribing.
How do credits work?
Credits pay for generation. The form shows the estimated cost before you submit; the model and selected settings determine the price. Unused subscription credits expire at renewal and do not roll over.
How do the plans differ?
Starter, Creator, and Pro differ in monthly credits and model access. Creator and Pro include Seedance 2.0 Standard and Seedance 2.5 creation and editing. See the pricing page for the current catalog and prices.
Images & video
Models, references, sizes, and saved prompts.
Which image and video models can I use?
Image options include Nano Banana, GPT-Image, FLUX, Seedream, Qwen, and Wan. Video options include Veo, Gemini Omni Flash, Seedance, and Sora. Model access varies by plan. The pricing table is the current catalog; the models page has examples.
How long does generation take?
Timing depends on the model, image size or video duration, and provider queue. Video can take longer than a single image. Dedicated Nano Banana batch jobs run asynchronously, so they are not an instant-generation option.
What sizes and aspect ratios are available?
Each model supports its own image sizes, video resolutions, and aspect ratios. The generation form shows the options for your selection. Product Images returns native dimensions, not a custom-sized export.
Can I use reference images or videos?
Yes, where the selected model supports them. Image models can use reference photos for generation or editing. Some video models support first and last frames, multiple references, or source-video editing. The form shows the supported inputs and limits.
Can I save and reuse prompts?
Yes. Your personal Prompt Library lets you save, edit, tag, favorite, and search prompts. Apply them in image, video, and standard batch forms, then edit before generating. Gemini batch does not use saved prompts. The library is personal, not shared with a team.
Product images
Source photos, batches, and marketplace use.
How do I turn a product photo into listing images?
Open Product Images and add a product photo or choose a saved product. Apply White background, Lifestyle, or Custom treatments and choose supported aspect ratios. Review the generation count and credit estimate, then generate. Check the results before uploading them to your marketplace.
Can I use the images on Amazon or TikTok Shop?
You can create images for these channels and adapt them for Shopify, Etsy, ads, or other storefronts. Amazon and TikTok Shop prompt presets are starting points. HummingBytes does not validate marketplace rules or publish listings; you are responsible for review and publishing.
Will my product look exactly like the source?
Reference images guide generation, but exact fidelity is not guaranteed. AI can change labels, proportions, colors, or small details. Use a clear source photo, describe what must stay unchanged, and compare every result with your actual product.
Can I create lifestyle images and infographics?
Yes. Product Images offers Lifestyle and Custom treatments. Prompts and presets can also guide infographic, comparison, and ad creative directions with supported models. Review all generated text and product claims before using them.
What makes a good source photo?
Use a sharp, well-lit photo with the whole product visible. Avoid heavy filters and obstructions. If the selected model supports multiple references, clean additional angles can help communicate packaging, texture, and small details.
Can I generate several product images at once?
Product Images applies treatments independently to one to eight products, with up to 50 generated images per run. Standard Batch supports up to 10 prompts per model workflow. Dedicated Nano Banana batch supports up to 100 prompts per workflow. These are separate generation tools with different limits.
Billing & account
Payments, cancellation, and invoices.
How do I pay for a subscription?
Payments are processed through Stripe. Choose monthly or annual billing on the pricing page. Checkout shows the payment methods available for your purchase.
Can I cancel my subscription anytime?
Yes. Cancel from your account settings. Your subscription stays active until the end of the current billing period.
What happens when I run out of credits?
Generation pauses when you do not have enough spendable credits. There is no overage charging. You can wait for renewal or move to a higher plan. Existing assets remain available under the normal access and retention rules.
How do refunds and failed generations work?
Credits are returned automatically for confirmed failures that qualify for a refund. Content generated and then blocked for a confirmed policy violation remains charged, even if the generation is marked as failed. For a payment refund request or a missing credit return, contact the billing team with your account email and the related generation or invoice ID. Payment refunds are reviewed under the current refund policy and are not automatic.
Where can I find my invoices?
Open the billing section in your account to access invoices and update billing details. Stripe also emails a receipt after a successful payment.
Rights & privacy
Commercial use and what happens to your files.
Can I use the results commercially?
All current public subscription plans include commercial-use rights. You must comply with the Terms of Service and applicable third-party model terms. Review the content and make sure you have the necessary rights before publishing.
Are my images used to train AI models?
HummingBytes does not use uploaded or generated assets to train AI models. Files are processed to deliver the service. Generated images and videos are retained while your paid subscription is active and remain available for 90 days after cancellation.
