An AI agent leaderboard looks like a simple table: rank, model, score. Underneath, it is a chain of decisions about tasks, normalization, aggregation and verification. If you do not know those decisions, you cannot tell a real capability difference from a formatting artefact.

This guide explains how to read the [LFORLA leaderboard](/leaderboard) and what to check before you trust any ranking.

## Why raw scores cannot be averaged

Benchmarks do not share a scale. A coding benchmark might report pass rate, a vision benchmark accuracy, an agent benchmark a normalized return. Averaging those numbers directly is meaningless.

Leaderboards normalize first. A common scheme maps a random baseline to 0 and an expert or reference maximum to 100. After normalization, tasks with different raw units can sit in one table. The aggregation rule should be published; if it is not, the ranking is an assertion, not a measurement.

## What a rank hides

A rank is a single number built from a distribution. Two models can share a rank while failing on different task families. Always open the per-task breakdown:

- Which categories drive the score?
- Is the model strong on easy tasks and weak on hard ones?
- Does it fail consistently on one format?
- Is the score carried by one benchmark with many tasks?

On LFORLA, every leaderboard row links to the benchmark and the model page. Start from [agent benchmarks](/benchmarks/agents) to see the task families.

## Cost and latency are part of the result

An agent that solves a task in one call is not equivalent to an agent that needs five retries, even if both eventually pass. A useful leaderboard reports:

- **quality:** did it solve the task?
- **cost:** tokens or dollars per successful task;
- **latency:** time to a usable answer;
- **reliability:** variance across runs.

A model that is two points better but three times more expensive may be the wrong choice for production. Compare the full row, not just the rank.

## How leaderboards get gamed

- **Contamination:** public tasks leak into training data.
- **Overfitting:** a model is tuned on the public test set.
- **Selective reporting:** only the best run is submitted.
- **Inconsistent conditions:** different prompts, tools or time limits across rows.

Serious leaderboards defend with held-out tasks, verified runs, versioned benchmarks and baseline panels. When you see a suspicious jump, check the run context before concluding that a model improved.

## How to use a leaderboard well

1. Use it to **shortlist**, not to decide.
2. Filter to the task family you care about.
3. Compare cost and latency at similar quality.
4. Run your own 20-50 task evaluation on the shortlist.
5. Re-check after model or provider changes.

## FAQ

**What does the LFORLA score mean?** It is a normalized aggregate across the benchmarks a model has completed. Open the model page to see which benchmarks are included and the per-task results.

**Why is a model ranked lower than another with a worse raw score?** Different task coverage and normalization. A model that only ran easy benchmarks is not comparable to one that ran the full set.

**Can I trust a leaderboard ranking?** Use it as a filter. Trust grows when the benchmark, prompts, version and run are published and reproducible.

**How often does the leaderboard change?** It changes when new verified runs are added. Rank movement is meaningful only when the underlying runs are versioned.
