UnverifiedThe current mainstream multimodal understanding approach is to align image features output by a visual encoder into the language model's embedding space via a projection layer or cross-attention, so that text tokens and image tokens participate in self-attention computation within the same sequence (early fusion).79% similarUnverifiedToken quota consumption for multimodal Agent tasks is often far higher than for pure text conversations, because image inputs must be encoded as visual tokens, each Computer Use screenshot introduces new visual input, and long multi-step reasoning chains accumulate intermediate reasoning tokens.75% similarUnverifiedThe embedding layer's function is to map tokens to vectors, the attention mechanism computes relationships between tokens, and Softmax converts scores into probabilities.72% similarUnverifiedThe user profile uses a layered memory architecture divided into three layers: permanent preferences, situational physiological information and immediate conversation context.70% similarUnverifiedAttention visualization shows the distribution of attention weights between tokens; activation probes train linear classifiers on hidden layers to test whether information is decodable, which is correlational evidence; feature attribution measures the contribution of each input dimension to the output.70% similar
