UL2
What is UL2?
UL2 is a unified framework for pre-training language models that perform well across a wide range of natural language processing tasks. It separates model architecture from training objectives, allowing flexible combinations of self-supervised learning methods. The core innovation is the Mixture-of-Denoisers (MoD) objective, which blends multiple denoising tasks to improve generalization. UL2 introduces mode switching, linking downstream fine-tuning to specific pre-training modes for better task adaptation. Scaled up to 20 billion parameters, UL2 achieves state-of-the-art results on over 50 NLP benchmarks, including language understanding, generation, reasoning, and knowledge grounding. It also excels at in-context learning, outperforming larger models like GPT-3 on zero-shot and one-shot tasks. The framework supports instruction tuning (Flan-UL2), further enhancing performance on complex reasoning and multitask benchmarks. Open-source Flax-based T5X checkpoints for UL2 and Flan-UL2 20B models are publicly available, facilitating research and application development.
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.
