Tell us what you plan to create and how often you expect to use AI. Get a suggested starting balance, then check model pricing for a closer estimate.
Video and agent workloads burn credits faster — the recommendation adjusts automatically as you switch scenario or usage level.
Cost matters. So does keeping your application running. GPTProto combines routing, upstream redundancy, and monitoring to help reduce interruptions when provider availability changes.
Major models run on redundant upstream channels. If one goes down, traffic shifts to a backup automatically — no manual fixes, no dropped traffic.
Major models are served through redundant upstream channels, so a single provider outage never takes your app with it.
Browse modelsContinuous monitoring with automatic traffic shifting — issues are routed around before your users ever notice a thing.

Hear from developers and creators using GPTProto for apps, content, and everyday AI workflows.
For a team already juggling DeepSeek, Kimi, Qwen, or other providers, a shared routing layer can be reasonable if it removes duplicated work and the fallback behavior is tested. GPTProto is one implementation of this approach.
I've been testing GPTProto recently, and it's honestly made my creative workflow much simpler. Instead of paying for multiple subscriptions, I can access several leading AI models from one place.
I turned this single prompt into a cinematic fantasy video using GPTProto. "Continuous 15-second cinematic shot, 4K resolution, hyper-realistic dark fantasy photorealism…"
I challenged myself to create a cinematic AI cooking short in just 15 seconds. I used GPTProto to bring the entire workflow together, from image generation to video, all in one place.
Made with Seedance 2.0 + GPT Image 2 on GPTProto. A Pixar-style commercial with the perfect glow.
What worked for me was pointing the cloud connections at GPTProto so the frontend only sees one endpoint and I just change the model name to swap. I am not rebuilding a connection from scratch every time.
I route the calls through GPTProto so a fallback is a config switch instead of a weekend rewrite when a model disappears. It turns "my default model just got export controlled" from an incident into a config change.
I used to switch between different AI tools just to compare results. Now I just use GPTProto. GPT-5, Claude, Gemini, Kimi, and more — all in one workspace.
I route the calls through GPTProto so the model id and latency land in one place regardless of which provider is behind it. The win is having the log schema consistent across providers.
I created this 15-second cinematic product video with GPTProto using Seedance 2.0, and I was really impressed by how smooth the workflow was.
GPTProto routes the character prompt and shot list to a top model on one API key: 20 minutes … voices it and burns in captions from the same key: 20 minutes.
Text, images, and voice are configured separately. You can keep OpenRouter for text and use GPTProto for visuals.
The call layer underneath the router is GPTProto, so swapping a model does not require provisioning a new provider integration. Changing models becomes cheap enough that the question stops being "should we change."
Start with an affordable AI API platform for everyday tasks, creative projects, and application development. Add funds to your account and use them across supported models, with no subscription required.
Get started. Great for testing the endpoint and trying new models.
The sweet spot for individual developers and small projects shipping to production.
Built for teams running production workloads. Bonus credits stack on already-discounted model pricing.
An all-in-one AI API gives you access to models from multiple providers through a single platform. GPTProto brings supported text, image, video, and audio models into one account, so you can explore different options without setting up a separate billing relationship with each provider.
An AI model aggregator brings models from different providers together in one catalog or service. As an AI API aggregator, GPTProto lets you access supported models programmatically and compare options for different tasks. Available features and request formats still depend on the model you choose.
One GPTProto API key works across the models supported by GPTProto. It does not provide access to every LLM on the market or replace credentials for unrelated services. Check the model catalog and documentation for availability, endpoints, and supported parameters.
The changes depend on your existing integration and the model you choose. For supported OpenAI-compatible requests, migration may involve updating your API key, base URL, and model ID. Test model-specific parameters, streaming, tool calls, and response handling before switching production traffic.
GPTProto offers discounts on select models, including supported GPT models. If you are comparing a cheap GPT API with other options, check the exact model version, input and output rates, caching rules, and any bonus credit. Use the pricing page and savings calculator to compare your expected costs.
Yes. You can try supported models through GPTProto’s browser tools for tasks such as writing and generating creative content. Developers can use the API to bring supported models into their own applications.
Yes. You can use one GPTProto account to try models listed in the catalog, compare their outputs, and review their pricing. Model availability changes, so check the live catalog for specific releases before planning a comparison.
Test the model using prompts and settings that reflect your real workload. Response time varies with the model, request size, output length, and upstream demand. Compare both speed and output quality before choosing a model for production.
Eligible top-ups add bonus credit to your account balance. Requests are then charged at the listed rate for each model. The bonus gives you more available credit; it does not change the model’s displayed unit price. Check the current top-up options for applicable amounts and terms.
Teams can use GPTProto to explore supported models and integrate them into business workflows. Contact us to discuss expected usage, integration requirements, and billing documentation. Confirm any specific support or service requirements before deploying.
