OCR-Memory: Novel Approach to Long-Horizon Agent Memory Storage
By
–
// OCR-Memory // Well this is a unique approach to store memory for long-horizon agents. Most of the agent memory systems compress trajectories into text summaries and hope the model remembers what matters. But that's where the information loss hides. Long-horizon agents need
