Different models vary across capability, scale, cost, and privacy boundaries. It has reached 4,214 GitHub stars, written primarily in Go.

Why now: Recent coverage — "vLLM Semantic Router v0.1 Iris: The First Major Release" — alongside renewed developer interest is driving current visibility.

• 4,214 GitHub stars, 683 forks — verifiable at github.com/vllm-project/semantic-router.
• Primary language Go; topics: ai-gateway, bert-classification, fine-tuning, golang.
• Licensed Apache-2.0.
