AI model comparison & hosted API
Compare top AI models side by side
Send one prompt to multiple models, then compare outputs, latency, and cost to pick the right model for your task.
Access leading providers through one hosted API with credits, pricing plans, and usage visibility—without wiring each integration yourself.
Side-by-side compare requires a free account. Guests get 5 Composer credits daily on supported models (see Pricing).

How it works
Three steps from prompt to a clear choice
Choose models & write your prompt
Pick the models you care about and enter a single prompt. Filter the catalog by task type when you need to.
Run once, get parallel responses
We run your prompt against each selected model so you can compare answers under the same conditions—including timing and estimated cost where shown.
Decide by quality, speed, and cost
Review outputs side by side, note latency and spend, and shortlist models that fit your workflow.
Explore by task type
Jump into the model catalog by common capabilities—availability depends on what your workspace has enabled.
Compare in the app, integrate via API
Use GenCMS for interactive evaluation or ship the same access pattern in your product.
Side-by-side compare
Signed-in users can run the same prompt against multiple models and review results in one place—ideal for picking a default model or validating quality before you scale usage.
Open CompareHosted API access
Call chat and image endpoints with API keys, with per-request usage reflected in your account or organization. Model routing options follow the product configuration you enable.
Providers & models in the catalog
Connect commercial and open models you configure. Availability and pricing follow your admin settings and each provider’s terms—not every provider is available in every deployment.
Frequently asked questions
What are credits?
Credits are the unit we use for billing. Usage per request depends on the model, prompt size, and output; heavier modalities (for example images) typically cost more than plain text when those models are enabled.
Can I try without signing up?
Guests can use the Composer with a limited daily allowance (5 credits by default) on models marked guest-accessible. Creating an account unlocks Compare, premium models (per your plan), higher limits, and API keys where enabled.
How does Compare work?
After you sign in, choose up to eight models, send one prompt, and review parallel responses with timing and cost indicators so you can judge fit fairly.
Do you offer an API?
Yes—hosted OpenAI-style endpoints (for example chat completions and image generation) using API keys, with usage and billing aligned to your workspace settings. See API docs for routes and authentication.
How is my data handled?
We do not use your prompts to train GenCMS. Requests are processed by the providers you select, subject to their policies. Privacy Policy
