DEEPDIVE: GETTING STARTED WITH MECHANISTIC INTERPRETABILITY

Neel Nanda is one of the pioneers of Mechanistic Interpretability (MI). This is his guide to getting into the field. It features 200 concrete open questions. MI is the study of the quantitative values of language models (e.g., actually looking at neurons). It is accessible as it doesn’t require significant computation, and is extremely promising as a research direction, although there has been minimal success to date.

FUYU-HEAVY MULTIMODAL MODEL OUTPERFORMS GEMINI PRO

Adept scaled up its Fuyu architecture and trained a larger version that is currently the 3rd best model on MMMU. The model also performs well on other tasks (e.g., achieving 40+ on HumanEval coding benchmark). There were fewer challenges with scaling this architecture than alternatives, in part due to its simplicity. However, there were still challenges with data i/o, memory bandwidth, and custom kernel development.

IF AI WERE CONSCIOUS, HOW WOULD WE KNOW?

The Turing Test and Searle's Chinese Room Thought Experiment are often cited in the discussion of AI consciousness, with the former testing if an AI's behavior is indistinguishable from a human's and the latter arguing that external behavior alone cannot prove consciousness. This debate highlights the difficulty in defining and recognizing consciousness in AI, as our understanding is primarily based on human experiences and functionalist approaches.
