## Description
Unified inference aggregation platform allowing users to dynamically route queries across frontier foundation models (Claude, GPT, Sonar, DeepSeek) grounded with real-time web verification.

## Access & Pricing
Free tier with standard routing; Pro ($20/mo) unlocks full model switcher across all frontier LLMs.

## Key Capabilities
- Hot-swap between top reasoning engines (Claude 3.5 Sonnet, GPT-4o, o1, Sonar 70B).
- Live web indexing harness with exact inline source citations.
- Custom focus harnesses: Academic, Computational, Writing, and Video synthesis.

## Alternatives & Replaces
- Individual LLM subscriptions ($20-$60/mo)
- Manual multi-model comparison tools

## Robbie's Take
**Robbie's Performance Take:** Ideal for latency-critical agent loops where fast token generation directly reduces user wait times. Benchmark output quality on your specific task before swapping out larger frontier reasoning models.
