Meaning without reference in large language models (arxiv.org)

In plain words: Meaning in a language model comes from how its internal states relate to one another, not from pointing at real-world things. On this view, models do capture real meaning, answering skeptics who say they mean nothing at all.

Abstract

The widespread success of large language models (LLMs) has been met with skepticism that they possess anything like human concepts or meanings. Contrary to claims that LLMs possess no meaning whatsoever, we argue that they likely capture important aspects of meaning, and moreover work in a way that approximates a compelling account of human cognition in which meaning arises from conceptual role. Because conceptual role is defined by the relationships between internal representational states, meaning cannot be determined from a model's architecture, training data, or objective function, but only by examination of how its internal states relate to each other. This approach may clarify why and how LLMs are so successful and suggest how they can be made more human-like.

Lots of excellent references showing LLMs have rich internal models such as color spaces. Good argument meaning doesn't require "grounding" in perceptions (with citations).
>Good argument meaning doesn't require "grounding" in perceptions

Well, LLM's "meaning" IS grounded in perceptions anyway: the training data it was based on was created by people with perceptions, whose experience (and thus written output) was shaped and influenced by them. It's just second hand influence by perceptions experienced by someone else, and also not in a real time feedback loop (like with humans).
