Top Free AI Content Detection APIs and Open Source models

What is AI Content Detection API?

AI Content Detection API, also called AI Text Detection, automatically recognizes and differentiates text content produced by Artificial Intelligence (AI) systems. This requires training AI models to identify patterns, language features, and distinct attributes unique to AI-generated text.

This process generally entails compiling and organizing datasets that comprise both human-created and AI-created text samples. By examining these examples, the AI models acquire the ability to distinguish between text produced by humans and text produced by AI systems.

This allows the identification and detection of AI-created content, which is critical in various areas such as content regulation, detecting plagiarism, and ensuring transparency and accountability in online communication.

Top Open Source (Free) AI Content Detection models on the market

For users seeking a cost-effective engine, opting for an open-source model is the recommended choice. Here is the list of the best AI Content Detection Open Source Models:

Free AI Content Detector: AI Detector API

The AI Detector API is a solution for businesses to detect automated content creation using machine learning algorithms. It accurately identifies machine-generated content by analyzing metrics such as sentence structure, grammar, and syntax.

This tool is especially useful for businesses relying on content creation for marketing, helping them distinguish between human and machine-generated content.  

Free AI Content Detector: GLTR

GLTR (Giant Language Model Test Room) inspects the visual footprint of automatically generated text. GLTR aims to take the same models that are used to generate fake text as a tool for detection.

GLTR has access to the GPT-2 117M language model from OpenAI.

Free AI Content Detector: GPTZero

GPTZero is an artificial intelligence model equipped with mathematical algorithms designed to discern whether a given text is authored by a human or generated by AI.

The media has generated considerable buzz around GPTZero for its ability to identify sentences produced by ChatGPT which has proven to be particularly beneficial for educational institutions. Despite the closed-source implementation, this serves as a replication of the solution.*

Free AI Content Detector: OpenAI (GPT-2 Output Detector)

This directory contains code for a GPT-2 output detector model, created by fine-tuning a RoBERTa model with outputs from the 1.5B-parameter GPT-2 model.

The dataset includes 250,000 documents from the WebText test set and, for each GPT-2 model trained on the WebText training set, 250,000 random samples (temperature 1, no truncation) and 250,000 samples generated with Top-K 40 truncation.

Free AI Content Detector: TypeTruth

TypeTruth is a Python library that detects whether a text is written by a human or AI. Ideal for fact-checking and content validation in the age of AI content generators.

It offers AI Content Detection at paragraph Level as well as sentence Level. The solution also provides visualizations to better understand the detection results, such as bar plots and heat maps.

Cons of Using Open Source AI models

‍While open-source models offer many advantages, they also come with some potential drawbacks and challenges. Here are some cons of using open-source models:

  • Not Entirely Cost Free: Open-source models, while providing valuable resources to users, may not always be entirely free of cost. Users often need to bear expenses related to hosting and server usage, especially when dealing with large or resource-intensive data sets.
  • Lack of Support: Open-source models may not have official support channels or dedicated customer support teams. If you encounter issues or need assistance, you might have to rely on community forums or the goodwill of volunteers, which can be less reliable than commercial support.
  • Limited Documentation: Some open-source models may have incomplete or poorly maintained documentation. This can make it difficult for developers to understand how to use the model effectively, leading to frustration and wasted time.
  • Security Concerns: Security vulnerabilities can exist in open-source models, and it may take longer for these issues to be addressed compared to commercially supported models. Users of open-source models may need to monitor for security updates and patches actively.
  • Scalability and Performance: Open source models may not be as optimized for performance and scalability as commercial models. If your application requires high performance or needs to handle a large number of requests, you may need to invest more time in optimization.
