Table of Contents

whatmodel.sh is a curl-first composite leaderboard that fits every public benchmark result it can find onto one item-response-theory scale, then tells you which models your specific machine can run, at what speed, and at what price.

What it is
#

A terminal-first leaderboard: curl whatmodel.sh returns the overall table, query parameters (ram=, gpu=, vram=, max=) filter it to what a given machine can run and afford, and ?format=json exposes the same data to scripts and agents. The scoring fits a single latent ability per model across 22,113 linked results with item response theory, pooling a level per evaluator run so one hot or cold setup cannot move a score (method). It covers 888 ranked text models fit from 22,353 published benchmark results across 575 benchmarks, plus separate image (203), video (142), TTS (181), and STT (184) lists, publishes raw results and benchmark definitions as downloads, and measures API speeds itself with the raw runs published (terms, API) (coverage as of 2026-10-29). The application is public: the repository the Show HN links (github.com/jakemanger/whatmodel) is MIT-licensed TypeScript holding the scoring pipeline and the generated leaderboard pages, created 2026-09-28. It is operated by Merlinsbeard Pty Ltd, a company with no public team page, and launched with a Show HN on 2026-10-12 (the thread).

Status
#

Live and actively maintained as of 2026-10-29: the board stamp reads 2026-10-29 04:56 UTC, the terms page was last updated 2026-10-19, and the JSON API, help surface, and per-model pages all served on the day of writing. The open-source claim now checks out at the repository level: the Show HN’s link resolves to a public repository (created 2026-09-28, MIT, TypeScript), holding the scoring pipeline and generated pages, with 43 stars, 2 forks, and a 2026-10-29 push as of this re-check; the terms still scope their CC BY-SA 4.0 grant to the compiled numerical dataset, so the application code’s licence lives in the repository rather than the data terms. The 2026-10-19 terms revision also discloses optional paid sponsorship placements in labelled areas, absent from this note’s 2026-10-17 read of the earlier terms. The community footprint is close to zero: the launch thread carries two points and zero comments, an HN search still returns no second story, and the repository’s 2 forks are the only visible contribution signal.

Strengths
#

  • The statistical grounding is the strongest in its kind: IRT with per-run level pooling, guessing-rate removal, saturated-test downweighting, and explicit uncertainty, with the prior art (Epoch’s Capabilities Index, LMArena, HELM) credited and differentiated.
  • Every result keeps a source link, and the raw data is re-downloadable (results.json, benchmarks.json), so a cited score can be traced and the board re-derived offline.
  • The machine-fit angle is unique in its category: RAM and VRAM estimates from GGUF headers, measured per-chip speed medians rather than estimates, and price-cap filters in the query itself.
  • Its own API speed measurements are published as raw runs, and a community bench script feeds reviewed submissions into the same tables.

Cautions
#

  • The method validation is self-reported: the hidden-test replay (about 85% pair accuracy, versus 77% for naive averaging) has no independent replication.
  • One operator, no team page, and near-zero community footprint (a two-point Show HN, a 43-star repository with 2 forks), so the code being public does not mean anyone has read it.
  • Scores shift as models arrive and scores from different scales are not comparable, a documented but easy-to-cite-wrong property.
  • The open-source grant splits three ways: MIT code in the repository, a CC BY-SA 4.0 licence covering only whatmodel.sh’s own dataset contributions, and the underlying benchmark numbers keeping their original licences.

Pricing
#

Free to use and to query. The terms (updated 2026-10-19) disclose optional paid sponsorship placements in labelled areas, with no prices published and no reader-facing paid tier, so no price history applies. The compiled numerical dataset is contributed under CC BY-SA 4.0; each underlying source keeps its own licence.

Compared to
#

  • LLM Stats: both are agent-facing composites, but LLM Stats normalizes public evidence into per-model entries with an MCP server, while whatmodel.sh fits one latent scale and answers the machine-fit question LLM Stats never asks.
  • BenchLM: both re-rank other boards’ outputs, but BenchLM labels how much evidence stands behind each position while whatmodel.sh collapses everything into a single fitted score and hands you the raw results instead.
  • Epoch AI: the methodological sibling, since Epoch’s Capabilities Index fits the same kind of model to benchmarks; Epoch is the nonprofit with the open datasets and the audits, whatmodel.sh the smaller operator adding run-level pooling and the hardware-fit layer.

Bottom line
#

Recommended for engineers picking a model that fits the machine and budget they already have, and for anyone who wants a comparable score with the raw results one download away. Not for citation as ground truth: one self-validated method, one operator, and no independent replication.

Changes
#

  • 2026-10-17 - Created after the trackers-and-leaderboards pass surfaced it in a candidate search and the coordinator resolved it the same run, with six sources fetched, the self-validation and thin-footprint cautions recorded as the critical angles, and the twelfth matrix column added.
  • 2026-10-29 - Rotation re-verification with every cited URL re-fetched (the oversized board and method pages via curl): coverage refreshed to 888 ranked text models from 22,353 linked results across 575 benchmarks as of 2026-10-29, the terms update of 2026-10-19 recorded with its new paid-sponsorship disclosure, and the open-source record corrected, the Show HN’s repository link resolving to a public MIT-licensed repository (43 stars, pushed 2026-10-29) that the creation run’s no-public-repository finding missed.

  • LLM Stats - the closest composite by kind, and the API-and-MCP alternative when the machine-fit question does not matter.
  • BenchLM - the other evidence-collapsing composite, worth reading beside this one for its per-position evidence labels.
  • Epoch AI - the nonprofit whose Capabilities Index is the published prior art for the IRT fit used here.
  • Model Selection for Coding Tasks - the decision layer these composite scores feed, and its argument for not trusting any one of them.
