OpenChat is an innovative library of open-source language models, fine-tuned with C-RLFT – a strategy inspired by offline reinforcement learning. Our models learn from mixed-quality data without preference labels, delivering exceptional performance on par with ChatGPT, even with a 7B model. Despite our simple approach, we are committed to developing a high-performance, commercially viable, open-source large language model, and we continue to make significant strides toward this vision. — Read More

Leo, Brave’s browser-native AI assistant, is now available in Nightly version for testing
… Brave Leo is a chat assistant hosted by Brave without the use of third-party AI services, available to Brave users on the desktop Nightly channel. The model behind Leo is Llama 2, a source-available large language model released by Meta with a special focus on safety. We’ve made sure that user inputs are always submitted anonymously through a reverse-proxy to our inference infrastructure. In this way, Brave can offer an AI experience with unparalleled privacy.
We’ve specifically tuned the model prompt to adhere to Brave’s core values. However, as with any other LLM, the outputs of the model should be treated with care for potential inaccuracies or errors. — Read More

Spread across four computer monitors arranged in a grid, a blue and green interface shows the location of more than 50 different surveillance cameras. Ordinarily, these cameras and others like them might be disparate, their feeds only available to their respective owners: a business, a government building, a resident and their doorbell camera. But the screens, overlooking a pair of long conference tables, bring them all together at once, allowing law enforcement to tap into cameras owned by different entities around the entire town all at once.
This is a demonstration of Fusus, an AI-powered system that is rapidly springing up across small town America and major cities alike. Fusus’ product not only funnels live feeds from usually siloed cameras into one central location, but also adds the ability to scan for people wearing certain clothes, carrying a particular bag, or look for a certain vehicle. — Read More
Image of Palestinian carrying children out of rubble shows signs of AI
An image of a man carrying children through rubble has been shared tens of thousands of times in social media posts linking it to Israel’s bombing of the Gaza Strip, which the Hamas-run health ministry says has killed more than 3,700 children. But experts say the image shows signs of artificial intelligence — and it was not published by news organizations with photographers covering the war, which was triggered by a deadly Hamas attack on Israel. — Read More
