RouterView

CI PyPI Supported Versions Downloads

RouterView is a terminal user interface for browsing models from OpenRouter's Models API. It visualizes model pricing, capabilities, and benchmark scores with interactive filtering and sorting.

The main motivation is to make cost-efficient models easy to find. You can customize how input and output token costs are weighted, then customize how that combined cost is weighed against model intelligence.

[!WARNING] This project is entirely vibe-coded, without even looking at a single line of code myself. It served for testing and setting up OpenCode. Seems to work fine, though.

✨ Features

  • Browse OpenRouter model pricing, capabilities, and benchmark scores in a terminal UI
  • Filter and sort models by provider, price, context size, modality, and benchmark score
  • Compare models using configurable blended-cost and cost-efficiency weights
  • Select recommended model IDs through a small public Python API
  • Cache model data for fast startup and offline use

🚀 Quick Start

pip install routerview
routerview

🐍 Python API

The public functions return OpenRouter model ID strings.

Find the model with the best cost efficiency using custom input/output and cost/intelligence ratios:

from routerview import get_efficient_model

model_id = get_efficient_model(
    cost_in_out_ratio=1 / 3,
    cost_intelligence_ratio=1 / 10,
)

Find the model with the highest intelligence score:

from routerview import get_intelligent_model

model_id = get_intelligent_model()

Find the model with the highest agentic score:

from routerview import get_agent_model

model_id = get_agent_model()

Find the model with the highest coding score:

from routerview import get_coding_model

model_id = get_coding_model()

Find the model with the highest Design Arena Elo:

from routerview import get_elo_model

model_id = get_elo_model()

🔑 OpenRouter Authentication

The Models API accepts anonymous requests. RouterView uses OPENROUTER_API_KEY automatically when it is set. Otherwise, RouterView connects without authentication. Run routerview --no-key to ignore the environment variable explicitly. The public Python functions accept use_api_key=False for the same behavior.
