Crun

Crun is a unified AI API platform for accessing video, image, audio, and text models through one interface. It helps developers integrate multiple model providers with API keys, usage monitoring, and credit-based pricing.

Crun

Unified API for top AI models

Crun is a unified AI API platform for developers and businesses that want to access top video, image, audio, and text models through a single interface. The site positions it as a way to simplify integration while still exposing a wide model catalog, including models for video generation, image generation, audio generation, and large language model tasks.

The product emphasizes developer workflow: create an API key, choose a model, send a request, and retrieve results from the same API. Crun also highlights OpenAI compatibility, usage monitoring, logs, and transparent credit-based pricing so teams can integrate models without managing separate providers individually.

Core features

Unified multi-model API

Access video, image, audio, and text models through one API instead of integrating each provider separately. The site highlights support for 100+ top AI models and lists providers such as OpenAI, Anthropic, Google, Alibaba, ByteDance, Kling, Runway, and Suno.

Large cross-modal model catalog

The platform includes a broad model catalog with video generation, image generation, audio generation, and LLM options. Example models shown on the site include Veo 3.1, Wan 2.6, Seedream 5.0 Lite, Vidu Q3, GPT Image 2, and Claude models.

OpenAI-compatible request flow

Crun presents itself as OpenAI-compatible and describes the API as a drop-in replacement with one-line migration support. The home page also shows a sample request flow using an API key and a CreateTask endpoint.

Transparent credit pricing

The pricing page shows transparent per-request pricing, credit-based plans, and higher-tier discounts. It also compares Crun’s prices with platform rates from official providers, FAL, and OpenRouter for some models.

Usage monitoring and account controls

The site advertises real-time usage and log monitoring, with a dedicated API Usage page and controls for tracking credit consumption. The API key page also shows IP whitelist, model limits, and safe-spend limits.

Developer-focused operations

The home page highlights 99.9% uptime, smart routing, global infrastructure, and developer docs with interactive examples. It also states that support is available 24/7.

Common use cases

  • Centralize multi-model integration

    Teams building products that need to switch between image, video, audio, or LLM models can use Crun to keep integration work in one place instead of wiring multiple providers separately.

  • Migrate an existing API workflow

    Developers migrating from an OpenAI-style workflow can use the platform’s compatibility positioning and sample request flow to adapt existing code with less rewrite effort.

  • Compare model costs and usage levels

    Product teams can compare model costs on the pricing page and use the credit plans to evaluate usage patterns before selecting a higher-volume tier.

  • Track usage and control spend

    Applications that need to monitor spend and request activity can use the usage page, logs, and safe-spend controls to watch consumption over time.

  • Prototype with cross-modal models

    Builders experimenting with media generation models can use the model catalog and API key workflow to test video, image, and audio outputs in a single platform.

Pros and Cons

Pros

  • Consolidates multiple media and text model providers behind one API.
  • Supports a broad catalog across video, image, audio, and LLM use cases.
  • Shows OpenAI-compatible positioning for easier migration.
  • Includes usage monitoring, logs, and account controls such as IP whitelisting and spend limits.
  • Publishes transparent pricing information and plan-based discounts on the pricing page.

Cons

  • The public evidence is light on concrete integration details such as SDK support, deployment steps, or supported programming environments beyond Python, JavaScript, and cURL examples.
  • Pricing is credit-based and model-specific, so comparing costs still requires checking the model table rather than relying on a single flat rate.

FAQ
