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.

OpenAI Image API

Generation, mask edits and multi-reference edits on the same models, via the Image API or the Responses tool. No per-image price for GPT Image 2.5, and the cost calculator doesn't cover it.

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

OpenAI Image API

  1. Pin quality and size. auto makes cost and latency vary per call
  2. Read usage in the response to track image tokens, it's the only cost signal for GPT Image 2.5
  3. Don't retry moderation_blocked or image_generation_user_error. Change the prompt first
  4. Honour Retry-After on 429 and add jitter, image limits are per minute and low at tier 1
  5. Move off gpt-image-1 before 2026-10-23 and off 1-mini, 1.5 and chatgpt-image-latest before 2026-12-01
