Documentação

Free2AITools — The Open-Source AI Registry

Discover, rank, and compare AI models, datasets, papers, tools, and benchmarks. Updated daily, scored by the Free2AITools Nexus Index (FNI).

Website: free2aitools.com

What It Does

  • Cross-source catalog — Models, datasets, papers, tools, and benchmarks from HuggingFace, GitHub, ArXiv, Ollama, Replicate, Civitai, and more
  • FNI Ranking — 5-factor composite score (Semantic, Authority, Popularity, Recency, Quality) with full breakdown in every API response
  • Hardware-aware filtering — filter models by VRAM, license, and task-category metadata (heuristic filters, not verified compatibility)
  • Daily Updates — Automated pipeline refreshes all data daily

For Developers & AI Agents

Model Selection API

curl -s https://free2aitools.com/api/v1/select \
  -H "Content-Type: application/json" \
  -d '{"task":"text-generation","constraints":{"max_vram_gb":8}}'

Returns FNI-ranked catalog entries with params, VRAM estimates, license, and a factual FNI factor summary (fni_summary) — not a fit verdict; the caller decides.

Model Comparison API

# <ID_1>,<ID_2> are id values taken from /api/v1/search results — substitute your own.
curl "https://free2aitools.com/api/v1/compare?ids=<ID_1>,<ID_2>"

Side-by-side comparison with FNI factor decomposition. Obtain ids from the Search API first; see the Developer Docs for a runnable search-first flow.

Search API

curl "https://free2aitools.com/api/v1/search?q=code+generation&limit=5"
