Use Case Recommendations
Best for: CometAPI
CometAPI is an OpenAI-compatible gateway to more than 500 models across OpenAI, Anthropic, Google and the open-weight ecosystem, reached with one key and one base URL. Migration is a two-line change — point the OpenAI SDK's base_url at api.cometapi.com/v1 and swap the key — which is the whole pitch: no per-vendor SDK, no separate billing relationships, no vendor lock-in when a cheaper or better model appears. The catalogue spans modalities rather than only text, covering text-to-text, image-to-text, PDF-to-text, text-to-image and text-to-video, with per-model unit prices published openly next to each provider's official list price. The published discount is consistent at around 20% below official pricing — Claude Opus 5 at $4 per 1M against a $5 list, GPT 5.6 at $4 against $5, Gemini 3.6 Flash at $1.2 against $1.5, Claude Sonnet 5 at $1.6 against $2, and image and video models priced the same way, some per second rather than per token. The site claims over 10,000 active developers, sub-400ms average response time and 99.9% uptime, and it publishes direct comparisons against OpenRouter, Fal.ai, Replicate, Kie.ai and WaveSpeed rather than pretending competitors do not exist. A pricing calculator and model-versus-model comparison pages help before you commit. Signup includes test credits with no card, and the interface is localised into more than twenty languages — a genuine differentiator against the English-only gateways.
Ideal use cases:
- •Teams or individuals who need 500+ models behind one openai-compatible endpoint
- •Teams or individuals who need two-line migration from the openai sdk
- •Teams or individuals who need text, image, video, audio and pdf modalities
- •Teams or individuals who need per-model prices published against official list prices
- •Anyone focused on api workflows
- •Anyone focused on llm-gateway workflows
Best for: UnoRouter
UnoRouter is a unified LLM router that exposes 302 models from more than 44 upstream providers behind one OpenAI-compatible API key, with automatic failover when a provider degrades. Because the endpoint is OpenAI-compatible, the same key works in application code and in the clients people actually use — the site publishes setup guides for coding agents including OpenCode, Cline, Roo Code, Kilo Code and Zed, for CLI tools including Aider, Codex, Gemini CLI and OpenClaw, for generic desktop and web chat clients, and for character and fiction clients including SillyTavern, Janitor.AI, Chub and RisuAI. That last category is unusual for a router and is served by a first-party chat surface on the site itself with characters, personas, lorebooks and presets, so the same credit balance covers both building and using. Of the 302 routable models, 203 are listed as free with no request limit on the free models and 99 are pay-per-use. The service publishes live counters — over 60.6 billion tokens served across 3.01 million requests at the time of verification — along with model rankings and a request inspector for debugging what was actually sent. Billing is credit-based and credits never expire: you can top up in fixed amounts by card or crypto with no card required to start, or subscribe, in which case every subscription tier delivers double the credit you pay for, released weekly.
Ideal use cases:
- •Teams or individuals who need 302 routable models across 44+ upstream providers
- •Teams or individuals who need openai-compatible endpoint usable from code, agents and chat clients
- •Teams or individuals who need automatic failover between upstreams
- •Teams or individuals who need 203 free models with no request limit
- •Anyone focused on llm-router workflows
- •Anyone focused on openai-compatible workflows
