Verdicts

Adobe Firefly API

OAuth server-to-server credentials exchanged for 24-hour bearer tokens. Enterprise contract only. No self-serve sign-up and no public price list.

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

Adobe Firefly API

  1. Call the REST async endpoints directly. @adobe/firefly-apis 2.0.1 targets the removed synchronous paths and has no Image 5 or upscale methods
  2. Cache the IMS token and refresh it before its 24 hours run out
  3. Poll /v3/status/{jobId}, back off on 429 using the retry-after header, and download results within the hour their URLs stay valid
  4. Send precise_upsampler_v1 to Upscale. creative_upsampler_v1 returns 422 since 2026-04-24
  5. Image 5 lives at /v4/images/generate-async. Image 3 and 4 stay on /v3/images/generate-async

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
