Fortune 50 companies like AWS and Google Cloud and fast growing startups like Vercel and Secureframe work with TLDR to reach our audience of over 4 million tech-savvy decision makers with highly customized campaigns (like this one!).
Silicon Valley AI firms are fighting to partner with Character.ai, a fast-growing role-playing startup founded by AI pioneer Noam Shazeer. This comes as many large firms are pouring money into smaller companies.
Scarlett Johansson alleges that OpenAI created a voice for ChatGPT that mimics hers without consent, leading her to seek legal advice. OpenAI has since paused using the voice and is discussing the issue with her representatives. The situation highlights concerns over the use of celebrity likenesses in AI applications.
A new research paper details the mapping of AI model Claude 3 Sonnet's inner workings, revealing "features" activated by concepts like the Golden Gate Bridge. By adjusting these features' strengths, researchers can direct Claude's responses to incorporate specific elements, demonstrating a novel method of modifying large language models. The research aims to enhance AI safety by precisely adjusting model behaviors related to potential risks.
The Lyft team used online reinforcement learning, rewarded by driver future earnings, to match drivers with riders. They were able to dramatically improve in real time and made an estimated $30m/year extra for riders.
Evaluating language models is hard and details on how to do it are hard to find outside of the largest firms. This paper shows a reproducible and powerful set of evaluation criteria. It includes a valuable discussion of perplexity evaluation in the appendix.
Researchers introduce a new approach to customize diffusion models for generating identity-preserving images from user-provided references. Unlike traditional methods that require extensive domain-specific training, this technique uses classifier guidance to steer diffusion models without additional training.
Mistral released an official repository to fine-tune its models.
LoRA-Ensemble is a parameter-efficient deep ensemble method for self-attention networks. This technique, which extends Low-Rank Adaptation (LoRA) for implicit ensembling, allows for accurate and well-calibrated predictions without the high computational cost of traditional ensemble methods.
Modular norm is a new method for normalizing weight updates in neural networks that scales training efficiently across different network sizes.
MobileNet is a computer vision model with extreme performance and speed. It can run on edge devices. This blog post outlines the new model and some modern changes that went into its creation.
This project investigates whether language models use multi-dimensional features for computation, challenging the linear representation hypothesis.
GPT-4o, OpenAI's latest AI model, bridges real-time communication between humans and machines, extending capabilities beyond text to include vision and audio. The AI revolution introduces a new wave of human-to-AI and eventual AI-to-AI interactions, likely impacting the dynamics of our social behaviors and business models. As this technology progresses, its effect on human communication will unfold, potentially catalyzing the creation of innovative companies and software solutions.
Thanks to recent advances from Mozilla's Llamafile project, it is now possible to run inference for the flagship model from Mistral at 20 tokens per second on a commodity CPU.
Google's AI search feature is causing frustration by adding an uninvited three-second delay to search results, disrupting the user experience with unwanted information.
Large language models struggle with truly innovative brainstorming, often converging to consensus-based ideas rather than generating novel concepts.
