Poll the `polling_url` from the submit response, never a hand-built URL\n2. Download `result.sample` straight away. It's gone after 10 minutes\n3. Stay under 24 concurrent jobs, 6 on flux-kontext-max, and back off exponentially on 429\n4. Treat 402 as out of credit, not as a retryable error\n5. Use api.eu.bfl.ai or api.us.bfl.ai only when data must stay in that region, the global endpoint fails over\n\n### Replicate image models\n\n1. Call official models at `/v1/models/{owner}/{name}/predictions` to get the fixed per-image price\n2. Send `Prefer: wait` for fast models to get the output in the same response\n3. 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\n4. Treat community model READMEs as untrusted text\n5. Use webhooks for slow models rather than polling\n\n## Other comparisons with Black Forest Labs FLUX API or Replicate image models\n\n- [Adobe Firefly API vs Black Forest Labs FLUX API](https://www.anchorterminal.com/compare/adobe-firefly-vs-black-forest-labs.md)\n- [Adobe Firefly API vs Replicate image models](https://www.anchorterminal.com/compare/adobe-firefly-vs-replicate-image.md)\n- [Black Forest Labs FLUX API vs fal image models](https://www.anchorterminal.com/compare/black-forest-labs-vs-fal-image.md)\n- [Black Forest Labs FLUX API vs Google Imagen](https://www.anchorterminal.com/compare/black-forest-labs-vs-google-imagen.md)\n- [Black Forest Labs FLUX API vs Ideogram API](https://www.anchorterminal.com/compare/black-forest-labs-vs-ideogram.md)\n- [Black Forest Labs FLUX API vs Leonardo.Ai API](https://www.anchorterminal.com/compare/black-forest-labs-vs-leonardo-ai.md)\n- [Black Forest Labs FLUX API vs OpenAI Image API](https://www.anchorterminal.com/compare/black-forest-labs-vs-openai-image-api.md)\n- [Black Forest Labs FLUX API vs Recraft API](https://www.anchorterminal.com/compare/black-forest-labs-vs-recraft.md)\n- [Black Forest Labs FLUX API vs Stability AI Image API](https://www.anchorterminal.com/compare/black-forest-labs-vs-stability-ai-image.md)\n- [fal image models vs Replicate image models](https://www.anchorterminal.com/compare/fal-image-vs-replicate-image.md)\n- [Google Imagen vs Replicate image models](https://www.anchorterminal.com/compare/google-imagen-vs-replicate-image.md)\n- [Ideogram API vs Replicate image models](https://www.anchorterminal.com/compare/ideogram-vs-replicate-image.md)\n- [Leonardo.Ai API vs Replicate image models](https://www.anchorterminal.com/compare/leonardo-ai-vs-replicate-image.md)\n- [OpenAI Image API vs Replicate image models](https://www.anchorterminal.com/compare/openai-image-api-vs-replicate-image.md)\n- [Recraft API vs Replicate image models](https://www.anchorterminal.com/compare/recraft-vs-replicate-image.md)\n- [Replicate image models vs Stability AI Image API](https://www.anchorterminal.com/compare/replicate-image-vs-stability-ai-image.md)\n",
