❯ Files Show Meta Agent Hatch Could Launch as Early as Late August; New Model Watermelon Set for October

TIMELINEAccording to internal documents seen by The Information reporter Jyoti Mann, Meta’s consumer-grade agent Hatch, built to rival OpenClaw, is planned to launch in late August or early September, with the company’s newest model Watermelon set for October. An explicit reason Meta built Hatch: OpenClaw is red-hot in the tech community but too complex for ordinary users. Hatch is designed to handle operations like shopping directly on Instagram; Meta has already tested it in simulated environments of DoorDash, Reddit, and Outlook.

CONVERGENCEHatch has been trained using Anthropic’s Claude Opus 4.6 and Sonnet 4.6, with a plan to switch to Meta’s in-house Muse Spark at official launch. Watermelon, though, is the heavier track — in July, Meta’s head of superintelligence, Alexandr Wang, told an internal all-hands that Watermelon has matched OpenAI’s GPT-5.5 on internal benchmarks, with training compute an order of magnitude higher than the previous-generation Muse Spark. The specific benchmarks remain undisclosed.

TIMINGPut the two dates together, and Meta has laid out a schedule in which model and product back each other up: Hatch seizes the entry point to consumer-agent use cases in September, then Watermelon swaps in as the underlying capability in October. The fallout hits Anthropic’s enterprise customer base — a product trained on your model drops you on launch day, and that script is likely to play out more than once. Model vendors, while supplying their biggest customers, are simultaneously cultivating their own replacements.
