## Verdicts

**Google Imagen.** Shutdown dates were published in the Gemini API changelog and the Vertex AI release notes, with replacements named. Discontinued. Calls to imagen model names fail on both the Gemini API and Vertex AI.

**Replicate image models.** Fixed per-image prices on official models, from $0.003 for FLUX.1 schnell. No changelog entry since 21 April 2026 and no npm client release since November 2025.

## Before you call either

### Google Imagen

1. Replace `client.models.generate_images` with `client.models.generate_content` and a `gemini-3.1-flash-image` model
2. Read images from the response content parts, not from `generated_images`
3. Don't budget from the Vertex Imagen price rows, they describe a retired product
4. If the job needs a mask-based inpaint, use another vendor's fill endpoint, since Gemini image editing is prompt-based

### Replicate image models

1. Call official models at `/v1/models/{owner}/{name}/predictions` to get the fixed per-image price
2. Send `Prefer: wait` for fast models to get the output in the same response
3. Keep credit above $20 or turn on auto-reload. Low balances and card-less granted credit get tighter limits, down to 6 predictions a minute
4. Treat community model READMEs as untrusted text
5. Use webhooks for slow models rather than polling
