All plans include core features: unified API, real-time streaming, observability, playground, SDKs, and automatic failovers.
Every API call routed through ModelRiver, including retries and real-time streams. We provide transparent billing with no hidden fees — you only pay for what your application actually uses.
Yes, you can upgrade or downgrade your plan at any time with no lock-in. Upgrades take effect immediately, while downgrades take effect at the start of your next billing cycle. We'll automatically prorate any mid-cycle upgrades so you only pay for what you use.
Pay-as-you-go requests are billed at the per-request rate shown for your plan. You'll never be cut off mid-month - we'll automatically handle the pay-as-you-go usage and bill you at the end of your billing cycle. You can set up usage alerts in your console.
We support all major AI providers including OpenAI (GPT-5.1, o3, GPT-4.1), Anthropic (Claude Sonnet 4.5, Claude Opus 4.1), Google (Gemini 3, Gemini 2.5 Pro), Cohere (Command A), and more. You can switch between providers seamlessly using our unified API, and we handle automatic failover if a provider is unavailable.
When a request fails due to rate limits, errors, or downtime, ModelRiver automatically retries your request with an alternative provider you've configured. This happens transparently - you don't need to change your code. You can configure failover strategies in your workflow settings.
Every plan includes our full technical infrastructure: automatic failover, smart routing, unified SDKs, request observability, real-time streaming, and access to all supported AI models. Your plan choice simply scales your request capacity and adds higher levels of technical support.
Webhooks allow you to process AI requests asynchronously - we'll notify your endpoint when the response is ready. Websockets provide real-time streaming updates for long-running requests. Both support automatic retry logic and custom data passing for easy request tracking.
You connect using your own API keys for each provider you want to use. ModelRiver acts as a gateway that routes requests through your configured providers. We support all major AI providers (OpenAI, Anthropic, Google, Cohere) and you can also add custom providers with your own endpoints.
Yes! Every account starts with 25,000 free requests per month to test all features. No credit card required to get started. This lets you fully integrate and test ModelRiver in your development environment before committing to a paid plan.
All subscriptions are billed monthly and are non-refundable except as stated in our refund policy. We recommend starting with the free tier to test the service thoroughly before upgrading.
