Verdicts

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.

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

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

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
