These systems can grasp three-dimensional space and physics, providing the foundation for everything from robots to smart glasses to self-driving cars \u2014 and a capability that today&#8217;s chatbots lack.

A language model can describe a room in elegant prose, but if you ask it whether a sofa will fit through a doorway or where a rolling ball will end up after bouncing off a wall, it\u2019ll work from patterns in the text it\u2019s been trained on rather than any actual grasp of the forces involved, and may get the answer wrong. World models aim to fill that gap. <\/p>\n","protected":false},"excerpt":{"rendered":"With everyone\u2019s attention fixed on powerful chatbots like ChatGPT and Claude, it\u2019s been easy to overlook the growth&hellip;\n","protected":false},"author":2,"featured_media":14072,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[8],"tags":[10255,53,3154,25,4460,387,182,144,377,10845,2425,10846,10844,701],"class_list":{"0":"post-14071","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-anthropic","8":"tag-alphabet-inc-cl-a","9":"tag-anthropic","10":"tag-anthropic-claude","11":"tag-artificial-intelligence","12":"tag-automotive","13":"tag-china","14":"tag-claude","15":"tag-nvidia-corp","16":"tag-robotics","17":"tag-smartphone","18":"tag-tencent-holdings-ltd","19":"tag-view","20":"tag-virtual-reality","21":"tag-wall-street"},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/posts\/14071","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/comments?post=14071"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/posts\/14071\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/media\/14072"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/media?parent=14071"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/categories?post=14071"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/tags?post=14071"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
