Muse Spark 2
watchingNot out yet. Meta hasn't released Muse Spark 2, and no release date is confirmed. What we know so far: no date from Meta; Oct 12: Meta shipped Muse Wonder (see its own entry) as a new line above Spark, so this hunt now waits on the Spark line alone; before that, Meta's next big model was reported under the codename Watermelon: Business Insider (Jul 3) said Alexandr Wang told staff it had 'caught up' with GPT-5.5, The Information (Aug 24) reported an October target, and on Oct 11-12 a Zuckerberg 'it is a BIG watermelon' clip spread on X, which MSL researcher Xinyao Wang confirmed in jest; Meta's Muse Wonder post does not use the codename; Spark is on 1.3 (Sep 2). Swept every 60 seconds across provider catalogs. The moment it answers on a public API, alerts fire: a text or a call on paid plans the second it's confirmed, then a free Chrome push and email about 15 minutes later.
