Verdicts

fal image models

Hundreds of image models, including FLUX, Nano Banana, GPT Image, Seedream, Recraft and Ideogram, on one key. Billing units vary by model, per image, per megapixel or per token.

Leonardo.Ai API

Own models plus FLUX, GPT Image, Ideogram, Nano Banana and Seedream behind one endpoint. No per-image price list outside the logged-in calculator.

Before you call either

fal image models

  1. Fetch https://fal.ai/models/<endpoint-id>/llms.txt before calling a model to get its schema and price
  2. POST to https://queue.fal.run/<endpoint-id> and poll or pass a webhook, rather than holding a call open on fal.run
  3. Use an API-scoped key for agents. ADMIN keys can deploy and manage apps
  4. Download outputs you need to keep. CDN retention defaults to at least 7 days, set X-Fal-Object-Lifecycle-Preference to change it
  5. Validate inputs before submitting, a malformed request can still be billed

Leonardo.Ai API

  1. Use POST /api/rest/v2/generations with a model name such as lucid-origin
  2. Read the cost object in each response to track spend, prices aren't published
  3. Send quality, not mode. mode was retired on 2026-05-04
  4. Set a webhook callback URL on the key instead of polling long jobs
  5. Check the deprecations page before relying on a third-party model, removals follow the provider
