Key features
  • OpenAI-compatible API for open-source frontier models (DeepSeek, Kimi, GLM, MiniMax)
  • Pay-per-token billing with no subscription or minimum monthly commitment
  • Infrastructure hosting removes the need to self-manage GPU deployment for these models
  • Multiple model families available behind a single consistent API interface
  • Pricing starting near $0.105 per million tokens depending on model choice
  • Single API key for 500+ models across major AI providers
  • Pay-as-you-go pricing around 20% below providers' list rates
  • One-line model switching without re-authentication
  • Support for text, image, video, and audio generation endpoints
  • No monthly subscription or minimum spend for standard usage
Pros
  • OpenAI-compatible API means minimal code changes for teams already using that interface pattern
  • Pay-per-token pricing avoids paying for idle capacity between usage spikes
  • Access to several current open-source frontier models behind one API instead of managing several accounts
  • Cuts the integration work of managing multiple provider SDKs and keys
  • Pricing undercuts going direct to most individual providers
  • Broad model coverage spans text, image, video, and audio in one API
Cons
  • No free tier, every API call consumes paid credit from the first request
  • Usage-based pricing makes monthly cost harder to predict than a flat subscription
  • Limited to open-source model families; no access to closed frontier models like GPT or Claude through this API
  • Founded in January 2025, with a limited track record so far
  • Adds a third-party dependency between a developer and the underlying model provider
  • Discounted pricing depends on CometAPI maintaining provider relationships and margins
