Cloudflare's open decision models Clef and Clef-flash are available for download from Hugging Face under Apache License 2.0 and are already in production use by Cloudflare's threat intelligence team, which classifies websites with them. The name Clef also appears as the title of PQube and CIRCLEfromDOT's Kusan: City of Wolves, a separate game released on July 30, 2026.
Two unrelated works share the name Clef, and the most recent coverage is the newer of the two. On October 6, 2026, Cloudflare released Clef and Clef-flash, open decision models under Apache License 2.0, downloadable from Hugging Face. Unlike Jev, which handles only text, Clef accepts image input. GIGAZINE reports it scored above Jev on Decision Index 0.2.1 while running faster, and Cloudflare's threat intelligence team already uses it to classify websites. Diogo Almeida, who made Jev, questioned benchmark validity.
Separately, PQube released Kusan: City of Wolves on July 30, 2026, for PC via Steam, PS5, Xbox Series X|S, and Nintendo Switch. The game is a top-down action shooter developed by CIRCLEfromDOT, set in the cyberpunk city of Kusan, and follows Jin, a former soldier turned mercenary protecting a girl named Haru, a psychic test subject implanted with a city-destroying weapon. The PC version holds a Metacritic score of 84 from six reviews, with praise for visuals and gameplay and notes that the high difficulty may deter some players. Physical editions are available for PS5 and Switch.
Coverage of the two works does not overlap. The Cloudflare coverage concerns model benchmarks and production deployment; the game coverage concerns a July 2026 release, its platforms, and its reception. The shared name is the only connection the stories establish.

CIRCLEfromDOT CEO Jung-kyu Yeom says Kusan: City of Wolves began from a single question: what if a cyborg John Wick dove into Hotline Miami? The Busan studio, founded in 2018, released the hardcore top-down shooter on July 31 for PC, PS5, Xbox Series X|S, and Switch, priced at 1,900 yen. It has 54 stages, Japanese support, and a former soldier named Jin as its lead.

PQube released Kusan: City of Wolves on July 30, 2026, for PC via Steam, PS5, Xbox Series X|S, and Nintendo Switch. The game is a top-down action shooter developed by CIRCLEfromDOT, set in the neon-lit cyberpunk city of Kusan. Players control Jin, a former soldier turned mercenary, who must protect a girl named Haru, a psychic test subject implanted with a weapon capable of destroying the city. The story involves Jin's former superior, Colonel Hoban, leading the armed group Diamond Wolves, and a government agent named Aine. The game features over 54 stages with varied gimmicks, boss battles, and a tech-tree system called TechTrix for customizing loadouts. Combat emphasizes melee attacks with Jin's prosthetic arm, the War Hand, and throwing knives, with a one-hit-death mechanic. The soundtrack is by Korean hip-hop artist Loptimist, and the story is presented through graphic novel-style cutscenes. Physical editions are available for PS5 and Switch.
