Perplexity open-sources Lily, a Metal inference server for exactly one checkpoint
Perplexity open-sourced Lily (Apache-2.0) in the pplx-garden repo: a Rust+Metal Mac inference server whose load-time validation admits exactly one checkpoint — mlx-community/Qwen3.6-35B-A3B-4bit with the HF revision pinned; any other architecture or quantization is rejected. It exposes a minimal OpenAI chat-completions subset, decodes greedily, keeps a two-entry LRU prefix cache, and requires Apple GPU family 10+ with macOS 26+. 704 stars at capture. AlphaSignal reports 1.35x over MLX-LM; the README states no such number but ships dated benchmark reports with reproduction steps.
Evidence: Perplexity's official repository README plus AlphaSignal and r/LocalLLaMA aggregation (BitShovel fetched and verified the repo on 2026-09-03). The 1.35x speedup does not appear in the README — it is an aggregator claim awaiting independent reproduction; the support surface is narrow (M5-and-newer Apple silicon, macOS 26+, a single 4-bit checkpoint); stars are attention, not proof of quality; this is not an independent review.

THE FULL RECORD · Full timeline
3 events retained by the site.
This object’s records stay together across live coverage, the watch pool and history. Every event links to its source record; corroboration and material changes have separate labels.
Dates use Beijing time. Open an event for its full record, original source and evidence. Corroboration adds support without counting as a material change.

RELATIONSHIPS · Evidence-backed connections
Every connection has a source and a scope.
These relationships come from evidence in the records. They describe specific uses or connections, not unconditional interchangeability.

- Qwen
Lily accepts only a pinned Qwen3.6-35B-A3B-4bit checkpoint. This does not imply support for the on-file Qwen3.8-Flash-Next or the whole Qwen family.
