agent.print_do(task)Upsonic is a next-generation framework that makes agents production-ready by solving three critical challenges:
1- Reliability: While other frameworks require expertise and complex coding for reliability features, Upsonic offers easy-to-activate reliability layers without disrupting functionality.
2- Model Context Protocol (MCP): The MCP allows you to leverage tools with various functionalities developed both officially and by third parties without requiring you to build custom tools from scratch.
3- Integrated Browser Use and Computer Use: Directly use and deploy agents that works on non-API systems.
4- Secure Runtime: Isolated environment to run agents
LLM output reliability is critical, particularly for numerical operations and action execution. Upsonic addresses this through a multi-layered reliability system, enabling control agents and verification rounds to ensure output accuracy.
Verifier Agent: Validates outputs, tasks, and formats - detecting inconsistencies, numerical errors, and hallucinations
Editor Agent: Works with verifier feedback to revise and refine outputs until they meet quality standards
Rounds: Implements iterative quality improvement through scored verification cycles
Loops: Ensures accuracy through controlled feedback loops at critical reliability checkpoints
Upsonic is a reliability-focused framework. The results in the table were generated with a small dataset. They show success rates in the transformation of JSON keys. No hard-coded changes were made to the frameworks during testing; only the existing features of each framework were activated and run. GPT-4o was used in the tests.
10 transfers were performed for each section. The numbers show the error count. So if it says 7, it means 7 out of 10 were done incorrectly. The table has been created based on initial results. We are expanding the dataset. The tests will become more reliable after creating a larger test set. Reliability benchmark repo
