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: Prizm
Prizm is a single API key over the major generative media models, sold on a prepaid balance with no subscription. The published roster covers video, image and voice — Veo 3, Kling, Seedance, Nano Banana, FLUX and ElevenLabs among them — so a user or an agent avoids maintaining separate accounts, separate billing relationships and separate API keys per provider. Three properties define the billing model and they are the reason to catalog it separately from a generic model gateway. Every generation displays its exact price before it runs. Failed jobs are refunded to the balance automatically, so you pay only for output you actually receive. And the balance is prepaid with nothing expiring and no minimums, which makes it a hard spend ceiling rather than a monthly commitment. The agent story is explicit rather than incidental: connect the Prizm key to Claude once and describe what you want in plain language, and Claude sees every model available, chooses the right one for the job, runs it and hands back the finished video, image or voiceover — all drawn from the same balance. The vendor's own worked example is an 8-second cinematic clip routed to Veo 3 at $0.40 from balance. An on-site studio covers text-to-video, image and voice generation directly for users who would rather not work through an assistant, and a playground allows evaluation before signup.
Ideal use cases:
- •Teams or individuals who need one api key across veo, kling, seedance, nano banana, flux and elevenlabs
- •Teams or individuals who need exact price shown before each generation runs
- •Teams or individuals who need automatic refunds on failed jobs
- •Teams or individuals who need prepaid wallet with no subscription, minimum or expiry
- •Anyone focused on model-gateway workflows
- •Anyone focused on video-generation workflows
