Fallom
Debugging Complex AI Agent Workflows
When a multi-step AI agent—involving sequential LLM calls, database queries, and API tool usage—fails or behaves unexpectedly, traditional logging is insufficient. Fallom’s end-to-end tracing allows developers to visually follow the entire execution path, inspect the state at each step, see the exact inputs and outputs of every tool call, and pinpoint precisely where and why an error occurred, drastically reducing mean time to resolution (MTTR).
Ensuring Regulatory Compliance for AI Products
For companies operating in finance, healthcare, or any sector bound by regulations like the EU AI Act, demonstrating accountability is non-negotiable. Fallom provides the necessary audit trail, documenting every AI decision, the model version used, user interactions, and data handling. This creates a verifiable record that proves due diligence, supports compliance audits, and helps build trustworthy, transparent AI systems.
Optimizing AI Performance and Cost Efficiency
Organizations scaling their AI usage often face ballooning, opaque costs and latency issues. Fallom’s detailed metrics allow teams to analyze which models, prompts, or users are driving the highest spend and latency. Engineers can use this data to optimize prompts, switch to more cost-effective models for certain tasks, cache frequent responses, and right-size their AI infrastructure, leading to direct improvements in unit economics and user experience.
Managing Production AI Rollouts and Experiments
Safely introducing a new LLM model or a major prompt update into a live application is risky. Fallom’s A/B testing and evaluation framework allows product teams to roll out changes to a small percentage of traffic, compare the new version’s performance against the baseline on real-world data, and monitor for regressions in accuracy or hallucinations before committing to a full deployment, minimizing operational risk.
