Efficiency × Cost

The perfect balance of efficiency & cost.

One gateway, pre-negotiated rates and pooled capacity — so every request is both cheaper and faster than wiring providers up yourself.

Up to 30% cheaper.

Volume pricing pre-negotiated with every provider and passed straight through — no tiers, no commitments, no annual minimums.

Save ~30% vs. going direct

<300ms routing.

A single gateway routes each request to the fastest healthy provider, with automatic failover — you get speed without babysitting vendors.

<300ms overhead · 99.99% SLA

Scale on demand.

Pooled capacity across providers absorbs spikes — high concurrency with second-level queueing and no per-vendor quotas to manage.

FAQ

Frequently asked questions.

What is LinkModel?LinkModel is one API for popular text, image, and video models — including GPT, Claude, Seedance, Kling, Nano Banana, and MiniMax Hailuo. One key, one schema, every model.How does pricing work?Each model has a transparent per-request price, with volume discounts shown before you run a request. Pay-as-you-go — no minimum spend, no monthly platform fee.Is LinkModel compatible with the OpenAI SDK?Yes. Endpoints are OpenAI-compatible, so migrating is usually a base-URL and API-key change rather than a rewrite.How fast do new models arrive?Day-0 for major releases. New models go live on LinkModel the moment providers ship them, with launch discounts on most.Is Zero Data Retention supported?Yes — by default. Prompts and outputs are not stored after processing. SOC 2 Type II and ISO 27001 certification processes are underway.Can I test models before integrating?Yes. Use the playground to run prompts, compare outputs side-by-side, and export the exact request as a working snippet.
