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.

Lo que dicen los usuarios sobreGPTProto.
Desde cambiar de modelo y gestionar respaldos hasta crear imágenes y videos, las personas usan GPTProto para distintos tipos de trabajo. Esto es lo que han elegido compartir.

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."

Respuestas a las preguntas detrás de la demo: control, modelos, memoria y costo.
01Can I build a roleplay chat app like Janitor AI with GPTProto?
Yes. GPTProto’s model APIs can generate replies for your own character chat app. You build the interface and manage characters, users, and conversation storage. Start with one character and one model, then use our roleplay API guide to plan your integration.
02Can I build an online character chat without coding?
A no-code builder can work if it supports authenticated API calls, secure server-side key storage, and conversation data. Configure a character, connect a model, and test a complete chat session. Check the builder’s support for streaming and error handling before choosing it for your app.
03Can I use multiple chat models with one GPTProto API key?
Yes. Use one key to access models currently available in the GPTProto catalog. Choose the appropriate model ID and request format for each integration. Check current prices, supported features, and content policies; a model appearing in the OpenRouter ranking does not automatically mean it is available on GPTProto.
04How do I give each character a different personality?
Include the character’s identity, speaking style, behavioral rules, and dialogue examples in the context sent to the model. Add the current scene and relevant conversation history. Test the same situations across your shortlisted models to see which follows the character most consistently.
05How can my app remember earlier conversations?
Save character profiles and chat history in your application. For each reply, send recent dialogue and relevant earlier details, or retrieve summaries of previous events. Keep requests within the model’s context limit. A large context window gives you room for more information; your app still manages persistent memory.
06Why do long roleplay chats use more tokens?
Each request may include the character profile, scene details, and earlier messages as input, followed by a newly generated reply as output. Sending more history increases input usage. Keep relevant details, summarize older turns when useful, and check actual token counts to understand your cost per reply.
07How do I estimate API costs before launching my app?
Measure average input and output tokens per reply in a small test. Multiply those amounts by your expected monthly reply volume and apply the selected model’s rates. Include calls for summaries and regenerated replies. Compare the same workload in the calculator, then refine your budget using actual usage.
08Can replies appear as they are generated?
Yes, where the selected model and endpoint support streaming. Your chat interface can display reply text progressively. Confirm streaming support in the model documentation and test interrupted connections, cancellation, and reconnection in your own app.
09How do I keep chats running when an API request fails?
GPTProto provides routing and automatic failover features to help handle upstream disruptions. Your app should also handle timeouts, controlled retries, and usage limits. Test under your expected traffic, monitor errors, and show a clear retry option when a reply cannot be completed.
10How are private conversations and character data handled?
API request content passes through GPTProto to the selected model provider. Our Privacy Policy explains content processing, short-term retention, and metadata logging; provider policies also apply. If your app has enterprise retention or routing requirements, discuss them with our team before deployment.
