Promptic - Trace, evaluate, and optimize AI agents and LLM prompts

The optimization platform for GenAI

Make GenAI perform

Promptic is the AI agent optimization platform: OpenTelemetry-native LLM tracing, automated agent evaluations, and one-click prompt optimization based on your individual business metrics.

Benchmark models, tune agents, and ship the configuration that performs best on your data.

01 —— GenAI Optimization Platform

Improve quality. Cut cost. Know what to ship. Promptic optimizes your prompts and agents for maximum performance. So you can easily compare candidates and choose the best-value fit for your use case.

03 —— How it works

From your data to a shipped configuration

Upload your use case data, set the KPIs that matter, and let Promptic benchmark and optimize every layer — automatically.

04 —— Tracing

Your entry point to GenAI optimization

Drop in Promptic to capture every LLM call, tool call, and step on OpenTelemetry. Tracing isn't the destination — it's the doorway: turn real agent data into optimization.

05 —— Closing the loop

Let your coding agent take over the optimization loop

coding agent
Compare three support-agent architectures and recommend the best one for quality, cost, and latency.

I’ll benchmark the router-based, tool-first, and single-agent variants on your evaluation dataset and compare the tradeoffs before suggesting an implementation change.

Three architectures are registered against the same dataset and KPIs. Now I can benchmark them head to head.

No single variant wins every metric — quality, cost, and latency each point at a different architecture. Let me weigh them against your priorities: quality first, then cost, then latency.

Router-based gives the best quality at acceptable cost, and its only weakness — latency — stays inside your budget. That’s the one to implement.

Before I implement the winner, let me read the traces where router-based still fails — so the fix targets the real problems instead of guesses.

The traces make the fix obvious: give billing its own route and scope each route’s tools so the wrong one stops getting retried — and the extra hop disappears once routing is explicit.

I’ll implement the router-based architecture with the two fixes the traces surfaced.

The router-based variant is implemented and ready to validate against the same dataset.
