The latest update to SaijinOS introduces a lightweight core featuring 20 personas and BPM-synchronized responses, significantly reducing the repository size from around 9GB to just 557KB. This is a game-changer as it emphasizes the importance of latency in human-paced AI, making it a feature rather than a flaw. The new declarative personas in YAML format allow for better routing based on context and role, promoting a clean deployment strategy that encourages rapid iteration over hoarding resources. This update not only enhances performance but also streamlines development, making SaijinOS a more efficient tool for developers.
