LLM leaderboard: compare AI models by score and cost

Which AI model fits the job, and what does it cost?

A searchable database of current large language models from 22 developers. Compare them on independent benchmarks, find the strongest model for each kind of AI agent, and see which models give the most capability for the money. Every score and price links to the page it came from.

Best by agent type

The strongest models for each kind of agent.

Each card ranks models on the independent benchmark closest to that job. A high score is a starting point for your own trial, not a guarantee on your tasks.

Coding agents

Agents that read a codebase, write and test changes, and work in the terminal, as in Claude Code, Codex or Cursor.

Turn on JavaScript to search and rank the models.

Price is the blended list price per million tokens, weighted 3 input to 1 output. It comes from the developer's own price list; for open-weight models, and where no developer price list could be read, it is the price a named host lists on OpenRouter (shown as a secondary source in the details). Select a row for specifications and every benchmark result with its source.

Methodology

How this database is built and checked.

Data as of November 12, 2026. 473 benchmark results and 48 list prices, each linked to the page it came from.

Gather from the source

Four research agents read each benchmark's own leaderboard or data file and each developer's model and price pages. Every value was copied as published, with the address it came from.

Use maintainers' results

Rankings use the results each benchmark publishes on its own board. Scores that developers report about their own models in announcements or model cards are not used. Some boards accept submitted runs; their notes say so.

Match names carefully

Benchmarks spell model names differently. Each name is matched to one entry. Earlier snapshots, previews, quantised builds and products not sold through the API are kept apart. When a model appears at several reasoning-effort settings, it is ranked on its best setting, which is shown with the score.

Red-team before publishing

Two further agents that did not collect the data re-checked values against the source pages and challenged the name matches, prices, costs and wording. Errors they found are fixed, or the value is removed, before publication.

Read the numbers with care

Benchmarks measure narrow tasks under one set of conditions, and results move quickly as models and agent tools change. Gaps of a few points are often within the margin of error. A model that ranks first here may not be the best on your own documents, processes or data. List prices change and some are introductory; open-weight prices depend on the host. Several well-known boards are not used to rank: SWE-bench, SWE-Bench Pro, OSWorld, tau-bench, BFCL and Aider have results for few or none of the models listed here, and METR's time-horizon board is no longer updated. This page is general information, not purchasing advice. Chmltech has no commercial relationship with any model developer or benchmark listed.

Work with us

Choose models on your own work, not on leaderboards alone.

Benchmarks narrow the field. The decision comes from testing two or three candidates on your own documents, processes and data, with cost, privacy and reliability in the scorecard. Chmltech helps Canadian businesses run that evaluation and build the agents that follow.
