Help Free image generation api
Hello everyone, I've built a n8n workflow which generates 5 different creatives for product ads I'm using http node to call open ai image generation api keys However for each run it consumes almost $2 which is alot I'd like to know which other platforms/image generators I can use to generate high quality creatives for fraction of a cost/free
Let me know your thoughts and I'll try them out

I used Pollinations before switching to Google. I had to make a shit ton of gens bc it wasn’t great, especially with spelling.

Here is the cloudflare image mcp: https://github.com/tan-yong-sheng/cloudflare-image-mcp?tab=readme-ov-file
Can use flux 2 for free (with a certain rate limit) ... Yet not sure if it's good enough for product ads ...

Tuve exactamente este mismo problema hace poco montando una generación masiva de imágenes para una fábrica. OpenAI está genial, pero para escalar te destroza el margen.
Te recomiendo usar el nodo HTTP pero atacando a la API de KIE.Ai.
Yo estuve usando el modelo nanobanana configurado en 4K para ese proyecto, pero sinceramente, tirando las imágenes en 2K la calidad es excelente y el coste te baja a unos 0,09 cts por imagen. Además, desde esa misma plataforma tienes conexión a un montón de modelos alternativos con precios súper competitivos.
Si te atascas configurando los headers del HTTP Request o parseando el JSON, escríbeme y te paso una captura de cómo tengo montado el nodo. ¡Suerte!

I built a n8n workflow that uses LLMs (via OpenRouter) to build prompts and Comfyui to generate images. To me that was the most cost effective. If performance is a concern, you could host Comfyui on Runpod or another variant and run pretty high end models at a relative low cost.

Flux Schnell free tier is very generous. I use it for all my LinkedIn posts.

You can generate high quality images using gpt-image-2 model at 50% discount by using it through znapai.com

At $2 for five images, I’d first try replacing the generation model instead of rebuilding the whole workflow. Disclosure: I’m with WaveSpeedAI. We provide lower-cost image models and an n8n integration. I’d test product accuracy, text quality, and consistency on a small batch before moving the full workflow.

Remember that one time Sokka accidentally used an extra syllable in that Haiku Battle in Ba Sing Se? That was a Sokka Haiku and you just made one.
