Key point
Replit built the ViBench and Telescope systems to improve the performance of agents based on closed models.
Details
Most production agents run on Closed frontier models whose weights cannot be updated. Therefore, instead of modifying the model itself, developers need to focus on Continual Learning at the Harness-level and Context-level.
To this end, the Replit team built two core systems.
- ViBench: Evaluates the functional success of app building based on Natural-language specs.
- Telescope: An automated system that analyzes Failure traces occurring in production environments and clusters them into actionable issue groups.
