💫 Cosmic Routers
While technically “routers” and not “models” - 💫 Cosmic Routers act through our OpenAI and Anthropic compatible API as if they were models themselves. They intelligently route every request to one of their underlying models.💫 Orbit
costa/orbitSWEBench: 57.9
Description: Orbit always includes current best practices in intelligent model routing - it is Costa’s “frontier” model router. Orbit uses a mix of routing strategies, including semantic task analysis, performance-based benchmarking,
and adaptive load balancing. It is designed to minimize manual intervention. It is particularly good at architecting projects and writing code in Python, C++, Javascript, Go and Ruby (although it does well in other languages).
Models Included:
anthropic/claude-sonnet-4.5
anthropic/claude-sonnet-4
anthropic/claude-3.7-sonnet

💫 Quasar
costa/quasarSWEBench: 56.2
Description: Quasar is a stable model router based on Avengers Pro routing logic. It trades performance for time efficiency in an extremely clever manner. Expect fewer updates to Quasar as it is relatively stable
