CometAPI

CometAPI brings 500+ AI models into a single API, so developers can use one key and one request format instead of maintaining many separate integrations and billing accounts.

One API for leading model providers

CometAPI supports a mix of text, multimodal, audio, and video models in one interface, including:

• GPT-5.x
• Claude Opus
• DeepSeek
• Nano Banana
• Doubao
• Image generation models
• Sora and Veo for video
• Whisper and TTS for speech

Cost optimization and spend control

You can switch between models and pricing options to match quality and cost for each task. Different billing schemes are supported, which can be useful for production workloads and A/B testing:

• Per token
• Per request
• Per second of runtime

Built for production use

CometAPI includes documentation, integration examples, and a blog with model breakdowns. This helps teams add AI to web apps, backends, and internal tools while reducing the overhead of supporting multiple AI providers.
