When to pick which

Both tools, one honest call.

Pick AI Generate when

You need video, image, music AND chat from one API
You're running an agency / team and want shared billing
You care about spend caps protecting your margin
You want auto-volume discounts without negotiating

Pick Replicate when

You already have a mature integration and switching costs outweigh savings
Your workload is fully within their catalog and you don't need the other modalities
You need a specific feature they ship first

Replicate is a model marketplace. AI Generate is a unified API surface.

Replicate exposes thousands of community-contributed models, each with its own input schema. AI Generate curates a smaller catalog (177 video, 72 image, 21 music & voice, 37 chat) but normalises them behind a single OpenAI-compatible request shape and a single billing surface — credits, not per-second compute. If you build for end-customers you trade catalog breadth for predictable margins and a clean SDK story.

Pricing predictability

Replicate bills per-second of GPU time. That is great for ML researchers; it is hard for a SaaS that needs to quote a fixed price to its own customers. AI Generate prices each call against a published per-unit table, syncs daily from upstream providers, and applies a volume tier on rolling spend — so the cost of generating a 10s 1080p video clip stays inside ±5% of what you quoted yesterday.

Chat is a first-class endpoint

Replicate ships a few llama variants for chat; AI Generate ships Claude, GPT-5 and Gemini through the same /api/v1/chat/completions surface, with streaming SSE and OpenRouter fan-out underneath. If your product needs both image generation and a Claude-grade reasoning step, AI Generate keeps the integration to one Bearer token.

Frequently asked

Why pre-paid credits instead of per-second billing?

Because most of our customers ship the API to their own customers and need a stable cost per output. Per-second billing makes that hard to quote. Each model row in our pricing table is per-unit (per image, per second of video, per million tokens), so the cost of a given output is deterministic.

Do you support custom / fine-tuned models?

Not yet — we route to the canonical hosted version of each model on the upstream provider. If you need a private fine-tune, Replicate is the better fit today.

Can I migrate gradually?

Yes. Both services are independent integrations. Top up $10 (1,430 credits) to test AI Generate and migrate one workload (chat, then image, then video) until the cost ladder pays for itself.

One integration, all the providers.

Same Bearer token. Video, image, music, chat. Pay from one credit pool.
