Pro: Unlock agentic-first decision loops

Drive meaningful AI pipeline improvements with ongoing measurements and actionable insights.

Reliability
Which models clear your quality bar consistently?

GPT-4o Mini looks like the obvious choice on cost. Twelve runs later, it passes half the time.

Drift
See exactly when and how often each model fails.

Same pipeline, same prompt, same RAG context. The variation is the model.

Daily benchmarks

Schedule your benchmark to run daily. Track quality, cost, and latency over time. Alert thresholds fire the moment a model drops below your bar – before your users notice.

Pass rate · quality threshold 95 · 12 scheduled runs (RAG pipeline)

Scoring: judge the text you already have

Score a draft, a reply, or a clause against a rubric, with a per-criterion verdict. Paste several versions to rank them against one standard. Reach it from the dashboard, the API, or a plain-language ask to your agent.

Four taglines, scored against one brand-voice rubric (out of 100)

Presets: save a run once, invoke it by name

Save the models, scoring, and context behind a run as a named preset, then run it by name from the dashboard, the API, or your agent. A curated starter preset ships ready to run, so your first comparison is one sentence.

Agent / MCP access

MCP is one way to reach LLM Prover, alongside the dashboard and the REST API. Any MCP-capable agent – Claude Desktop, Cursor, Amazon Q, VS Code – discovers over 40 tools automatically and runs comparisons, scoring, benchmarks, and preset-driven runs without leaving its workflow. Agent analysis is included: it checks the trace of a Kiro or Claude Code workflow and shows where it wasted money, time or effort. See agent evaluation.
