Changelog

What shipped on reranker.uk — demo improvements, new guides, and site infrastructure.

11 Aug 2026 — Real Chinese URLs, and a 2026 model refresh

  • Chinese lives at /zh/ — every page is now pre-rendered in Chinese at its own URL with a self-referencing canonical, instead of a client-side toggle that left all three hreflang tags pointing at one page
  • Lighter pages — translation moved to build time, so ~200 KB of dictionaries no longer ship to the browser
  • Sitemap is generated — built from the page tree with hreflang alternates and lastmod from git, replacing a hand-maintained file that had drifted
  • Cohere Rerank 4 — rerank-v4.0-pro and rerank-v4.0-fast replace v3.5; 32k context, billed per search
  • Voyage rerank-2.5 — 32k context and instruction following; the index table's per-doc pricing was wrong and is now per token
  • Jina v3 numbers firmed up — 0.6B, 61.94 BEIR nDCG@10, 64 docs in a 131K context
  • Honest Qwen3 rows — dropped an unverifiable "~75+" figure for the 8B; reports put the 4B slightly ahead of it
  • Design refresh — fluid type scale, a real elevation ramp, and one focus-visible treatment site-wide

25 Jun 2026 — Model landscape refresh

  • Qwen3-Reranker — 0.6B / 4B / 8B rows + deep review page
  • Jina v3 — listwise flagship; tiny kept for browser demo
  • Table adds — gte-reranker-modernbert-base, NVIDIA nv-rerankqa / Nemotron
  • Self-host / homepage / chooser — GPU default Qwen3-4B; bge remains CPU path
  • Score footnotes — MTEB-R* vs classic BEIR; next review Oct 2026
