The promise of AI chat assistants: they solve 90% of the problems users have (by looking up the docs and telling them) My reality: need to spend 10 minutes trying to get to a human, to solve an issue I need customer support to look into Around minute 8 I sign up to a competitor

Andrej Karpathyβs take on AI coding agents feels grounded. The industryβs chasing full autonomy when models still hallucinate too much. Agents that churn out a thousand lines of code leave you either blindly trusting them or slogging through reviews. These tools should embrace their fallibility.

Our paper "Prediction Hubs are Context-Informed Frequent Tokens in LLMs" has been accepted at ACL 2025! Main points: 1. Hubness is not a problem when language models do next-token prediction. 2. Nuisance hubness can appear when other comparisons are made.
