Run time and cost

This model costs approximately $0.12 to run on Replicate, or 8 runs per $1, but this varies depending on your inputs. It is also open source and you can run it on your own computer with Docker.

This model runs on Nvidia A40 (Large) GPU hardware. Predictions typically complete within 3 minutes. The predict time for this model varies significantly based on the inputs.

Readme

This model detects whether text is AI generated vs created by a human and outputs the percentage liklihood that the text is generated by AI (From smaller LLM’s like LLAMA to ChatGPT, GPT-4, etc)

This model is using the methods from the paper Fast-DetectGPT: Efficient Zero-Shot Detection of Machine-Generated Text via Conditional Probability Curvatureere from ICLR 2024.

Note that it works better the longer the text is and it is slow to boot up but fast once it’s warmed up.
