Is AIgateway a drop-in replacement for Replicate?

Yes if you're using Replicate's OpenAI-compatible surface. Change the base URL to https://api.aigateway.sh/v1 and swap the API key — every other line of code stays the same. Streaming format is unchanged.

Will my existing model slugs work?

Some slugs match exactly, others differ. Check /models for the AIgateway equivalent of each model you call. Replicate's naming convention → AIgateway uses provider/model.

How long does migration take?

60 seconds if you run `aig migrate replicate` (manually, since CLI automation isn't shipped for this source yet). Test suite should be green immediately because the OpenAI surface is preserved.

Can I get a credit match for my Replicate invoice?

Yes — email your last Replicate invoice to switch@aigateway.sh and we match the credit (up to $1,000) within 24 hours. See /switch/replicate for details.

What's different about AIgateway's pricing?

5% per call (our entire revenue model) + payment-processor passthrough at top-up (Stripe's standard rate). No monthly fee, no seat fee, no per-model surcharge. Cached requests get a 50% discount. $5 free credits on signup, redeemable on a curated edge-tier shortlist (Kimi K2.6, FLUX-2 Klein, Whisper Turbo, Aura 2, Gemma 4 vision, BGE-M3, Llama Guard 3), valid for 7 days. Topups never expire and unlock the full catalog.

Migrate

Migrate from Replicate

OpenAI-compatible alternative to Replicate's async-by-default model. Same access to FLUX / Stable Diffusion / Llama / etc., but sync chat completions and unified billing.

CLI automation for Replicate isn't shipped yet — you'll do this manually below. PRs welcome at packages/aig-cli/src/commands/migrate.ts.

TL;DR — three lines

# 1. set your AIgateway key
export AIGATEWAY_API_KEY="sk-aig-..."

# 2. change the base URL
base_url="https://api.aigateway.sh/v1"  # was https://api.replicate.com/v1

# 3. search-and-replace the env var name

What changes, line-by-line

The table below is what aig migrate replicate rewrites. If you're doing it by hand, do these in order.

Thing	Replicate	AIgateway
Base URL	https://api.replicate.com/v1	https://api.aigateway.sh/v1
API key env var	REPLICATE_API_TOKEN	AIGATEWAY_API_KEY
Auth header	Token …	Authorization: Bearer …
Request shape	Custom Replicate JSON	OpenAI-compatible (chat/images/etc.)
Polling	Required for most models	Streaming for text, async-job pattern for video

Before / after — Python (OpenAI SDK)

BEFORE · Replicate

from openai import OpenAI

client = OpenAI(
    base_url="https://api.replicate.com/v1",
    api_key=os.environ["REPLICATE_API_TOKEN"],
)
r = client.chat.completions.create(
    model="anthropic/claude-opus-4.7",
    messages=[{"role": "user", "content": "Hi"}],
)

AFTER · AIgateway

from openai import OpenAI

client = OpenAI(
    base_url="https://api.aigateway.sh/v1",
    api_key=os.environ["AIGATEWAY_API_KEY"],
)
r = client.chat.completions.create(
    model="anthropic/claude-opus-4.7",
    messages=[{"role": "user", "content": "Hi"}],
)

Behavioral notes

Replicate's custom request shape doesn't map 1:1 — you'll need to rewrite the request bodies, not just the URL. Text models go to /v1/chat/completions, images to /v1/images/generations, video to /v1/videos/generations.
Webhooks: Replicate uses URL-callback webhooks on completion; AIgateway has the same pattern for async jobs at /v1/jobs.
No CLI automation — manual rewrite. See /docs/images and /docs/async-jobs for the equivalent shapes.
