In the long video comprehension task, the M3-Agent demonstrates three key advantages:
- Memory efficiency:While models such as Gemini require re-encoding the entire video into a context window, M3-Agent only needs to retrieve the relevant entity nodes through memory mapping. For example, when processing a 1-hour video, the former needs to consume about 200K tokens, while the latter only needs to activate about 50 relevant nodes.
- Depth of reasoning:In the HOTPOT-QA video test set, M3-Agent achieves an accuracy of 721 TP3T for problems requiring three-level reasoning, which is 181 TP3T higher than that of Gemini-1.5-pro. This stems from its ability to chain reasoning through graph-edge relationships, such as "object taken by person A → the object belongs to person B → therefore A and B have an interaction".
- Spatio-temporal modeling:The unique timing encoder accurately records the relative time of events. Tests have shown that it is 27% more accurate than the GPT-4o in answering questions such as "It happened after X and before Y", which is especially important in scenarios such as surveillance and analysis.
These advantages make M3-Agent irreplaceable in open scenarios that require long-term memory (e.g., home robotics), but its modular design also implies higher deployment complexity.
