Rohan Paul highlights Rayline's ARC, a model router claiming near-frontier quality at a fraction of the cost.
- Its technical report claims 97.4% of Opus 5.5 quality at 14.3% of the inference cost (7.1% with local models)
- Integrates with gateways (llama.cpp, vLLM Semantic Router, Hugging Face, OpenRouter) and coding/agent tools like Claude Code, Cursor, Cline, Codex
- Two modes: Rayline runs inference and returns a finished response, or the Decisions API returns just the model + reasoning level to run on your own infrastructure
- Routing can be tuned to each team's quality bar and negotiated pricing, with control over where data goes
