OpenChatKit

What is OpenChatKit?
OpenChatKit provides tools and models for building conversational AI applications that can understand and respond to user instructions. It offers instruction-tuned language models, a moderation system to filter unsafe content, and a retrieval system that enables the AI to access external data for up-to-date answers.
What distinguishes OpenChatKit is its combination of large-scale pre-trained models like GPT-NeoXT-Chat-Base-20B and fine-tuning support for models such as Llama-2-7B-32K-beta. It also integrates a flexible retrieval mechanism to augment responses with relevant external information, which is not common in many open-source alternatives.
The toolkit supports training, fine-tuning, and inference workflows, with monitoring options through tools like Weights & Biases. It is designed for developers and researchers who want customizable conversational AI solutions with transparent, open-source code and collaborative development.
OpenChatKit includes detailed documentation and environment setup instructions to facilitate use. Its models are trained on the OIG-43M dataset, created through collaboration between Together, LAION, and Ontocord.ai, ensuring a robust foundation for dialogue applications.
Overall, OpenChatKit enables the creation of specialized or general-purpose chatbots with safety features and the ability to incorporate real-time data through retrieval-augmented generation techniques.
ZeroGPT

What is ZeroGPT?
ZeroGPT scans pasted text or uploaded files to estimate whether ChatGPT, GPT-5, Gemini, Claude, or other LLM models wrote it, highlighting AI sentences with percentage scores. The free detector handles up to 15,000 characters per check and sits inside a larger writing suite with humanizer, plagiarism, grammar, and summarizer tools.
Standalone AI detectors often flag whole documents without sentence-level detail, while plagiarism scanners ignore whether the prose itself came from a model. ZeroGPT combines DeepAnalyse highlighting, PDF detection reports, batch uploads, and companion tools like an AI image detector and ZeroCHAT assistant on the same domain.
Teachers, publishers, recruiters, and SEO teams use ZeroGPT when they need fast LLM screening before accepting submissions. Free accounts work without a card, premium MAX and EXPERT subscriptions unlock higher character limits such as 350,000 characters per scan, and pay-as-you-go API access is available for custom integrations.
