# Contributing to LibreFang Model Catalog
Thank you for helping keep the model catalog up to date! This guide explains how to add or update model entries.
## How to Add a New Model
### 1. Fork & Clone
```bash
git clone https://github.com/<your-fork>/model-catalog.git
cd model-catalog
```
### 2. Find the Right Provider File
Each provider has its own file in `providers/`. For example:
- OpenAI models go in `providers/openai.toml`
- Anthropic models go in `providers/anthropic.toml`
If the provider doesn't exist yet, create a new file (e.g. `providers/newprovider.toml`) with the `[provider]` section and your `[[models]]` entries.
### 3. Add Your Model Entry
Append a `[[models]]` block to the provider file:
```toml
[[models]]
id = "new-model-id" # The exact API model ID
display_name = "New Model Name" # Human-readable name
tier = "smart" # frontier | smart | balanced | fast | local
context_window = 128000
max_output_tokens = 16384
input_cost_per_m = 2.50 # USD per million input tokens
output_cost_per_m = 10.0 # USD per million output tokens
supports_tools = true
supports_vision = false
supports_streaming = true
aliases = [] # Optional short names
```
### 4. Validate
```bash
python scripts/validate.py
```
This checks:
- All TOML files parse correctly
- Required fields are present
- Tier values are valid
- Costs are non-negative
- No duplicate model IDs
### 5. Submit a Pull Request
Push your branch and open a PR. The PR template will guide you through the checklist.

## Guidelines
- **Pricing must be in USD per million tokens** -- convert from other units if needed
- **Use the exact model ID** that the provider's API expects
- **Don't guess** -- only add data you can verify from official sources
- **One provider per file** -- don't mix providers in a single TOML file
- **Keep aliases short** -- 1-3 word abbreviations that users would naturally type
