modelx

A fast, cross-platform terminal UI (TUI) and command-line tool for exploring, comparing, and querying large language models. Browse context windows, pricing, modalities, and capabilities across 167 providers and ~5,700 models, sourced live from models.dev. Built in Rust with ratatui.

Why modelx?

Comparing LLMs means juggling context limits, input/output token prices, cache pricing, reasoning support, modalities, and knowledge cutoffs across dozens of providers. modelx puts the whole catalog one keystroke — or one shell command — away, and keeps it fresh automatically.

Features

3-pane terminal UI — Providers → Models → Detail, fully keyboard-driven, with fuzzy search, sort, and capability filters.
Model comparison tool — pick 2+ models and compare their numeric fields as a bar chart, an X-vs-Y scatter plot, or an exact-numbers table, including derived value metrics like context-per-dollar.
Rich headless CLI — query models by any field with comparison operators (input_cost<=3, context_limit>=200000, release_date>=2025-01-01, name~opus), then sort, limit, count, choose fields, and output as plain, CSV, JSON, or Markdown.
Providers & fields commands — list vendors, inspect every model field and its type, or dump one model’s full JSON with modelx show.
Auto-refreshing cache — the catalog updates automatically when it’s older than 12 hours, so every query hits fresh data. Works offline from cache too.
Cross-platform — prebuilt binaries for Linux, macOS, Windows, and FreeBSD.

Install

Grab a prebuilt binary for your platform from the latest release, or build from source:

git clone https://github.com/alejandro-llanes/models-explorer
cd models-explorer
cargo build --release   # binary at target/release/modelx

Quick start

# Launch the interactive terminal UI
modelx

# The 10 cheapest models with a big context window
modelx models --filter "input_cost<=1" --filter "context_limit>=200000" \
              --fields provider_id,id,context_limit,input_cost --sort input_cost --limit 10

# Every Anthropic "opus" model, as JSON
modelx models --provider anthropic --filter "name~opus" --fields id,name,input_cost --format json

# List providers, or show one model's raw detail
modelx providers --filter anthropic
modelx show anthropic claude-opus-4-5
