Oqoqo is a platform for building custom evaluations and private benchmarks for real-world agentic tasks. It runs experiments at scale on fully managed cloud infrastructure, isolating each task in its own sandboxed environment with the files, tools, and credentials the agent needs. Users can compare multiple agents, models, and treatments on the same tasks, then review full step-by-step trajectories showing tool calls, errors, and failure points. Oqoqo also surfaces insights like token inefficiencies, interface friction, and pass-rate lift across experiment iterations.
