Exact day (2026-04-16) is from press coverage (Bloomberg/SCMP); fal's official partner page says only 'unveiled in April 2026'. access 'beta': limited early access by application on happyoyster.cn, but fal (official API partner) lists it as 'available now'. maxSessionSec 180 = Directing mode; Wandering is 60 s at 480p. Voice input also supported. A third fal path /explore exists but its API id is unconfirmed. A 'Happy Oyster 2 Preview' for the 2026 Yunqi conference is reported by a third-party listing only — not confirmed on any Alibaba page, not added.
