A lightweight, crash-resilient Discord bot built in Rust with [poise](https://github.com/serenity-rs/poise) and [serenity](https://github.com/serenity-rs/serenity). Model Radar monitors [OpenRouter](https://openrouter.ai)'s live model catalog for free LLMs (`:free` and exact $0 pricing) and dispatches configurable release alerts and role pings directly to your Discord server.

## ✨ Features
## Features
- **Automated OpenRouter Monitoring:** Periodically polls the public OpenRouter models API (`/api/v1/models`) with configurable intervals.
- **Accurate Zero-Price Detection:** String-based decimal parsing identifies genuine free-tier models (including scientific notation like `0e-9999`) while rejecting precision artifacts, non-zero pricing, and tiered overrides.
- **Live Auto-Updating Dashboard:** Running `/watch` posts a persistent public dashboard embed in your channel that automatically refreshes every poll interval (`POLL_SECONDS`), featuring new drops at the top and active stealth/experimental models directly on the first page.
- **Interactive Component Buttons:** Multi-page `/free-models` and `/status` views include interactive `[◀ Prev]` and `[Next ▶]` buttons with automatic timeout disabling.
- **Model ID Autocomplete:** Live slash command autocomplete for `/model <id>` to instantly find any model in the catalog as you type.
- **Direct OpenRouter Links:** Embed titles link directly to the model's page on OpenRouter for quick browser inspection.
- **Pricing per 1M Tokens:** Model inspection computes readable rates per 1 Million tokens (e.g. `$0.15 / 1M tokens`).
- **Flexible Subscription Filters:**
- `free_only`: Target free models or watch all new catalog entries.
- `search`: Filter releases by model identifier or name (e.g., `qwen`, `llama`, `coder`).
- `min_context`: Ignore models with context windows below a given token threshold (e.g. `32768`).
- `min_context`: Ignore models with context windows below a given token threshold (e.g. `32,768`).
- `compact`: Dense notification rows for high-volume channels.
- **Controlled Opt-In Role Pings:** Role pings configured per server (supports custom roles as well as `@everyone`).
- **Opt-In Role Pings:** Server-level ping configuration supporting custom roles as well as `@everyone`.
- **Crash-Resilient State:** Subscriptions and catalog states are stored atomically (`.tmp` write followed by atomic filesystem rename) to guarantee state integrity across crashes and container reboots.
- **Queue Bounds:** Unreachable alert channels (e.g., deleted channel or revoked bot permissions) are capped at 50 queued events, preventing unbounded state growth.
- **Queue Bounds:** Unreachable alert channels (e.g., deleted channel or revoked permissions) are capped at 50 queued events, preventing unbounded state growth.
- **Discord API Safety:** Strict UTF-16 character limit enforcement and markdown character escaping prevent broken embeds or Discord 400 Bad Request rejections.
- **Live Auto-Updating Dashboard:** Running `/watch` posts a persistent public dashboard embed in your alert channel that automatically refreshes every poll interval (`POLL_SECONDS`), featuring new drops at the top and active stealth/experimental models directly on the first page.
- **Interactive Discord Buttons:** Multi-page `/free-models` and `/status` views include interactive `[◀ Prev]` and `[Next ▶]` buttons with automatic timeout disabling.
- **Model ID Autocomplete:** Live slash command autocomplete for `/model <id>` to instantly find any model in the catalog as you type.
- **Direct OpenRouter Web Links:** Embed titles link directly to the model's page on OpenRouter for quick inspection in the browser.
- **Dry-Run Diagnostic Mode:** Test public catalog availability and parsing without needing a Discord token (`--check`).
