Meta plans to introduce an automated agent system named Hatch in the coming weeks. The platform will enable third party digital assistants to talk to one another through chat messaging and could be offered under a high tier paid plan. The company is also building a foundation model called Watermelon scheduled for release later this year.
Chinese artificial intelligence lab Z.ai launched GLM-5.3 using the identical 743-billion parameter foundational architecture as its prior version, relying entirely on post-training refinements. The model's score on the command-line Terminal-Bench 3.0 benchmark jumped from 4.6 to 28.3 within 59 days. However, performance improvements across other general testing categories remained substantially smaller, showing uneven gains.
