1.1 Workflow description

Title: Generate 100+ ad variations from one image with Fal.AI Nano Banana and GPT-5
Workflow name: Generate 100+ ad variations from one image with Fal.AI Nano Banana and GPT-5

Scale Your Creative Strategy: 100+ Creative Ads from 1 Image using Fal.AI, Nano Banana model and GPT-5.1

This workflow turns a single reference image into up to 100 high-performing ad variations using Fal.AI's Nano Banana model and GPT-5.1. Simply upload your inspiration to a form, and watch as unique, campaign-ready images appear in your Google Drive.

Why use this?

Scale Instantly: Turn one idea into a full campaign without manual design work.
Smart Variations: Uses GPT-5.1 to analyze your reference and rewrite prompts based on proven creative recipes (Metaphors, Pointers, Comparisons).
Cost Effective: Generates 100 variations for approximately $4.60 (vs. hundreds of dollars with manual design).

How does it work?

You submit the form with your reference image, company name, and selected "Creative Recipe."
GPT-5.1 analyzes your image deeply ("Describe the image extremely comprehensively...").
It rewrites the prompt into multiple unique variations based on your chosen strategy (e.g., "The Metaphor Bake").
Fal.AI generates the images using the fast and efficient Nano Banana model.
The results are saved directly to your Google Drive output folder.

What do you need?

Google Drive Credentials: To upload your reference and save the results (Guide).
OpenAI API Key: For GPT-5.1 analysis and prompt engineering.
Fal.AI API Key: For generating the images (ensure you have credits).
A Google Drive Folder: One for inputs and one for outputs.

💰 Estimated Costs

Fal.AI: ~$4.00 for 100 images ($0.04/image).
GPT-5.1: ~$0.60 for 100 descriptions (Input: $1.25/1M tokens, Output: $10.00/1M tokens).
Total: ~$4.60 per 100-ad campaign.

Important: The Prompt Strategy

This automation doesn't just copy your image. It uses a specific instruction to "Describe the image extremely comprehensively. don't leave anything behind". This ensures GPT-5.1 captures every visual detail—lighting, composition, and mood—before rewriting it into new creative angles.

That’s it! Just fill the form and let the automation build your ad campaign.

Send daily LinkedIn post drafts with Tavily, Groq Llama 3.3 and Gmail

## Quick overview This workflow runs daily at 8 AM to rotate through a topic list, research it with Tavily web search, generate a LinkedIn post and image prompt with Groq (Llama 3.3 70B), create a Pollinations.ai image URL, and email you the post with the image attached via Gmail. ## How it works 1. Runs every day at 8:00 AM on a schedule. 2. Selects today’s topic from a rotating list based on the day of the year. 3. Searches the web with Tavily to fetch up-to-date results for the selected topic. 4. Uses a Groq-hosted Llama model to write a LinkedIn post and a matching image prompt grounded in the Tavily results. 5. Builds a Pollinations.ai image generation URL from the image prompt and downloads the generated image file. 6. Emails the post text with the image attached via Gmail, and sends a text-only fallback email if image generation or download fails. ## Setup 1. Add a Groq API credential to the Groq Chat Model node. 2. Create a Tavily API key and configure HTTP Header Auth with `Authorization: Bearer <YOUR_TAVILY_KEY>` for the Tavily Search request. 3. Connect a Gmail OAuth2 credential and update the recipient email address in both Gmail send steps. 4. Edit the topic list in the topic-selection code step if you want different rotating themes. ## Requirements - Groq API key (free tier available) - Tavily API key (free tier — 1,000 searches/month) - Gmail account (OAuth2) ## Customization - Edit the topic list inside the "Pick Today's Topic" code node to change what subjects the post rotates through. - Change the Groq model in the "Groq Chat Model" node if you want a different LLM (e.g. a smaller/faster or larger Groq model). - Adjust the schedule trigger if you want a different posting time, or swap the Gmail "send to" address to deliver the draft to someone else for review. ## Additional info This workflow emails you a draft for manual review before posting — it does not post to LinkedIn automatically. If image generation fails, a text-only fallback email is sent instead so you never miss the post text.

Generate VEO3 videos from form ideas with ChatGPT, fal.ai, Drive and Gmail

## Quick overview This workflow collects a video idea via an n8n Form, uses OpenAI to turn it into an optimized prompt, generates an 8-second VEO3 video with native audio via fal.ai, saves the MP4 to Google Drive, and emails the Drive link via Gmail. ## How it works 1. Receives a submission from an n8n Form with the requester’s email, a plain-English video idea, and a selected style. 2. Uses OpenAI (via an AI Agent) to convert the idea and style into a structured VEO3 title and detailed prompt returned as JSON. 3. Cleans and parses the AI JSON, creates a filename-safe title, and sets the generation parameters to 16:9 and 8 seconds. 4. Submits the prompt to fal.ai’s queue endpoint for the fal-ai/veo3 model and gets a request ID. 5. Polls fal.ai every 30 seconds until the job status returns COMPLETED. 6. Retrieves the final MP4 URL from fal.ai, downloads the video, uploads it to Google Drive, and emails the Google Drive web link to the requester via Gmail. ## Setup 1. Create a fal.ai account, generate an API key, and replace `YOUR_FAL_AI_API_KEY` in the fal.ai HTTP request headers. 2. Add an OpenAI API credential in the OpenAI Chat Model node and select the model you want to use. 3. Connect Google Drive OAuth2 and replace `YOUR_GDRIVE_FOLDER_ID` with the target folder ID where videos should be saved. 4. Connect Gmail OAuth2 for sending emails, then activate the workflow and use the Form URL (path `veo3-video-generator`) to submit requests.

Generate presentation decks from prompts with Encelade

## Quick overview This workflow starts a presentation generation job in Encelade from a prompt and outline hints, polls Encelade for completion, and outputs the finished deck link (or stops with an error if generation fails). ## How it works 1. Starts when you manually execute the workflow in n8n. 2. Sends the topic, slide count, audience, tone, theme settings, and outline hints to Encelade to generate a 6-slide presentation. 3. Waits 20 seconds and then checks the Encelade session status using the returned session ID. 4. If the session phase is not finished, it keeps waiting and rechecking until the phase changes. 5. When the phase is "done", it returns the generated deck link and project PID. 6. When the phase is "failed", it stops the workflow and raises an error with the failure details. ## Setup 1. Install and configure Encelade credentials in n8n for the Encelade node. 2. Update the generation inputs (topic, page count, outline hints, audience/tone, theme mode, and media provider) to match the deck you want to create. 3. Ensure the workflow has enough time to complete by adjusting the 20-second wait interval if your Encelade generations typically take longer.
