What is img2prompt?
Img2Prompt is an AI tool developed by Methexis Inc that generates approximate text prompts with style information matching a given image. The tool is specifically optimized for use with Stable Diffusion (clip ViT-L/14) text-to-image diffusion models. It uses the CLIP Interrogator methodology, which leverages OpenAI's CLIP models to analyze images against various artists, mediums, and styles, then combines these results with BLIP captions to suggest text prompts for creating similar images.
Key features include image-to-text conversion using OpenAI CLIP models, text prompt generation with BLIP captions, API access for integration into workflows, and GitHub repository access for self-hosting. The tool analyzes image content, style, and intricate details to produce prompts that accurately reflect characteristics suitable for recreating similar-looking versions of images or paintings using Stable Diffusion.
Img2Prompt is designed for artists, designers, content creators, researchers, and anyone involved in visual storytelling or AI art creation. Users can copy the generated text prompts directly to Stable Diffusion to recreate similar versions of their input images. The tool runs on Nvidia T4 GPU hardware with predictions typically completing within 24-27 seconds.
img2prompt pricing
Pricing model: Paid
Img2Prompt uses Replicate's pay-as-you-go pricing model with charges calculated by the second. The tool costs $0.000225 per second on Replicate's Nvidia T4 GPU hardware, which translates to $0.81 per hour. Users are billed only for actual usage time and do not incur costs during periods of inactivity since the platform scales down to zero. The model costs approximately $0.0055 per run (about 181 runs per $1), though this varies based on inputs. As open source software under MIT license, users can also run the model on their own hardware free of charge beyond initial hardware investment.

- Self-hosting requires technical expertise and hardware investment
- Optimized only for Stable Diffusion, not other text-to-image models
Frequently asked questions about img2prompt
What does Img2Prompt do?
Img2Prompt generates approximate text prompts with style information that match a given image. It analyzes the image content using OpenAI CLIP models, tests it against various artists, mediums, and styles, then combines these results with BLIP captions to suggest text prompts that can be used with Stable Diffusion to recreate similar-looking versions of the image or painting.
What models does Img2Prompt use?
Img2Prompt uses OpenAI's CLIP models (specifically clip ViT-L/14 optimized for Stable Diffusion) and Salesforce's BLIP models. The CLIP Interrogator methodology tests images against artists, mediums, and styles, while BLIP provides captions that are combined to create the final text prompt.
Is Img2Prompt free to use?
Img2Prompt is open source software released under the MIT license, so you can run it on your own hardware free of charge. However, when running on Replicate's hosted platform with Nvidia T4 GPU hardware, it costs $0.000225 per second with pay-as-you-go pricing. There is no free tier on Replicate itself.
How fast is Img2Prompt?
Predictions typically complete within 24-27 seconds on Replicate's Nvidia T4 GPU hardware. The predict time varies significantly based on inputs, but the tool is designed to be a fast and efficient solution for generating text prompts that match images.
What is the input format for Img2Prompt?
Img2Prompt requires one input: an image (string). The image should be provided as a string, typically a URL to the image file. The image is the only required field and the model returns a string output containing the text prompt.
Can I use Img2Prompt with other AI art models?
Img2Prompt is specifically optimized for Stable Diffusion (clip ViT-L/14). While the generated prompts might work with other text-to-image models, the tool is designed and tested primarily for compatibility with Stable Diffusion. Users are encouraged to copy the generated prompts to Stable Diffusion for best results.
How do I access Img2Prompt's API?
Img2Prompt is accessible via API on the Replicate platform. Replicate provides client libraries for Node.js, Python, Elixir, and other languages for easy API integration. You can run the model with an API using the fields documented in Replicate's API documentation.
Can I run Img2Prompt locally?
Yes, Img2Prompt is open source under the MIT license and you can run it on your own computer with Docker. The tool is based on the open-source CLIP Interrogator notebook by @pharmapsychotic, which is available on GitHub for local installation and customization.
What output does Img2Prompt provide?
Img2Prompt outputs a single string containing the approximate text prompt with style information. The output includes descriptions of the image content, artist names, medium references, style tags, and other attributes that can be used with Stable Diffusion to recreate similar images. Example output includes phrases like 'a cat wearing a suit and tie with green eyes, a stock photo by Hanns Katz, pexels, furry art'.
Who created Img2Prompt?
Img2Prompt was created by methexis-inc and is available on Replicate. It is a slightly adapted version of the CLIP Interrogator notebook by @pharmapsychotic. The creators encourage users to support @pharmapsychotic via ko-fi or follow @AIMindFlow and @pharmapsychotic on Twitter for more AI content.
