OpenAI has launched ChatGPT Enterprise, an AI chatbot with enterprise-grade security and privacy, unlimited higher-speed GPT-4 access, longer context windows, and advanced data analysis capabilities. Some websites, including Amazon, Quora, and NY Times, have already blocked OpenAI's GPTBot, a language model that can generate text indistinguishable from human writing. Researchers from the Australian National University have proposed a dual-stage optimization technique using adversarial fine-tuning to generate and detect problematic content in large language models. LongBench, the first bilingual, multi-task benchmark for long context understanding, provides a more rigorous evaluation of long context understanding, which is crucial for developing language models that can handle longer sequences.
