Limitations & Considerations

Response depth on complex queries: Pi may occasionally return generic or surface-level answers when faced with highly technical, niche, or multi-layered questions.
Internet dependency: Real-time processing means you need a stable connection; offline use is not supported.
Learning curve for full potential: Some advanced features (e.g., instructing Pi to adopt specific roles or contexts) may require experimentation to master.
Privacy and data handling: As with any AI that learns from interactions, users should be mindful of what personal information they share, and review Pi’s privacy policy.
Response variation: Because Pi continuously learns, answers can shift over time, which might surprise users who expect static, consistent outputs.
No native API or SDK (public): For developers looking to integrate Pi into custom applications, there is currently no widely documented API, limiting extendability.
