OpenRouter Model Family Taxonomy

Preview of how /models permaslugs would group into families for -latest aliases. Only date fragments (2024-05-13, 04-28, 20260224) and pure quantization markers (fp8, awq, gguf) are stripped. Everything that defines a distinct product — parameter size, MoE active params, minor versions, thinking/instruct/base/preview, and product variants (mini, nano, chat, codex, vl, …) — is preserved. Grouped by provider, sorted by total model count.

Most fragmented families

These are the biggest buckets — good sanity check that collapse rules aren't over-merging distinct products.

These permaslugs are filtered out before family resolution — OpenRouter meta routers, embeddings, and ~latest aliases.
