Cursor is in talks with investors for a funding round that would value it at $50 billion, nearly double its valuation last fall. The discussions are preliminary and may not result in a funding deal. One of the fastest-growing startups of all time, Cursor is a central player in tech's vibe coding era. It has attracted financing from top names in venture capital and the tech industry. The company's last financing round, announced in November, boosted its valuation to $29.3 billion.

Personal Computer is a version of Perplexity Computer that handles things on a nearby computer. It handles requests from users and directs multiple AIs to complete tasks. It is effectively a project manager that delegates tasks to other AIs before combining the results and presenting them. Perplexity has specifically named the Mac Mini as a platform that Personal Computer can run on. There is currently a waitlist for access.

Autoresearch is a tool that ingests a training script and a metric and then edits code, runs experiments, checks if the metric improved, keeps or discards, and repeats. It allows researchers to optimize models overnight, even without any machine learning experience. Andrej Karpathy used it to squeeze 11% more speed out of his GPT-2 training. Shopify's CEO used the tool to train a 0.8B model overnight that outscored his previous 1.6B model.

Large language models are probably not currently being used in mission-critical ways, but this will change within 20 years, when 99% of the workforce will be AIs. Our future civilization will run on AI labor. We need to think through some extremely important questions about who this future workforce will be accountable and aligned to, and who gets to determine that. The only way to preserve a free society is to make laws and norms saying it is unacceptable for the government to use AI to enforce mass surveillance, censorship, and control. Individual acts of corporate courage will not solve the problem.
