This release has been yanked by its maintainers, and will be ignored by installers, except when explicitly specified.
Consider using release 1.0.0 instead.
Reason given by maintainers: Retired. ModelSpec is available only as a hosted service at modelspec.dev.
ModelSpec is a decision engine for AI models. It reads a spec, filters models and offerings against its constraints, and explains the decision from a versioned offline snapshot. The catalogue starts as YAML and Markdown, then exports to JSON on Cloudflare Pages (modelspec.dev). No database is on the serving path.
- Site: modelspec.dev · decide · graph
- CLI contract:
docs/cli-contract.md - Current state:
docs/handoff/current.md - Agent entry:
AGENTS.md
Quick start
pipx install modelspec-dev
modelspec snapshot fetch
modelspec vocab templates
modelspec decide --template budget-coding
snapshot fetch is the only networked command. After that, vocab and decide read the cache.
The supported interface is docs/cli-contract.md:
modelspec snapshot fetch [--origin URL]
modelspec snapshot status [--json]
modelspec vocab [SECTION] [--json]
modelspec decide [SPEC.yaml] [--template ID] [--check] [--json]
Legacy (v1)
The following commands keep the retired fixed-benchmark contract for existing callers:
modelspec offline rank <use-case> [...]
modelspec offline fit [<hardware-id>]
modelspec offline class-fit [<task>]
The root rank, search, compare, hardware, info, stats, and gaps
commands are also legacy v1 commands and are outside the contract. gaps
works offline from the local YAML cards; the other root legacy commands need a
local FalkorDB.
Serving path
models/*.md ──▶ pipeline/build.py ──▶ static JSON on Cloudflare Pages
(modelspec.dev /api/*.json)
│
CLI `snapshot fetch` ───────────────────────┘
Wizard / 3D graph read the same JSON in the browser.
FalkorDB is optional local graph exploration only. It is not required to rank, fit, or render the sites.
Contribute
Read CONTRIBUTING.md. Sign off commits (git commit -s) to certify the DCO — not a copyright assignment. Every fact carries a source and the date it was read; unknown means an empty field.
Cards live in models/{provider}/{model-slug}.md. Edit and open a PR.
License
Two licences, because the code and the corpus want different things.
| Part | Licence |
|---|---|
| Code (everything outside the data directories) | MIT |
Data (models/, benchmarks/, hardware/, hosts/) |
CC BY-SA 4.0 |
The corpus is share-alike: build on it, including commercially, but if you redistribute it or a derivative, credit ModelSpec and publish yours under the same terms. The code is permissive so the CLI can go anywhere. Full text in LICENSE and LICENSE-DATA.
Every card and page records the sources it draws on and the date each was read. Those sources keep their own licences.
