Human review has moved; responsibility has not. Alex Casquete explains the engineering behind AI-generated code at Plain Concepts.

Warsaw brought software development professionals together for an event focused on AI agents. Organised by Callstack, Agent Conf 2026 dedicated two days to tools and experiences in building applications with agents.

At the Plain Concepts Research team we have spent several months evaluating the performance of a real-time conversational avatar system, with the goal of identifying the most suitable configuration for a production environment. Throughout this research we analyzed different conversational AI models and hardware configurations, measuring latency, response stability and overall system performance. The results allowed us to identify which components have the greatest impact on user experience and which combination offers the best balance between performance and consistency.
