They can do so on Hugging Face.<\/p>\n<p>This follows its release of GLM-5 Turbo, a faster version, under only proprietary license last month. <\/p>\n<p>The new GLM-5.1 is designed to work autonomously for up to eight hours on a single task, marking a definitive shift from vibe coding to agentic engineering.<\/p>\n<p>The release represents a pivotal moment in the evolution of artificial intelligence. While competitors have focused on increasing reasoning tokens for better logic, Z.ai is optimizing for productive horizons. <\/p>\n<p>GLM-5.1 is a 754-billion parameter Mixture-of-Experts model engineered to maintain goal alignment over extended execution traces that span thousands of tool calls. <\/p>\n<p>&#8220;agents could do about 20 steps by the end of last year,&#8221; wrote z.ai leader Lou on X. &#8220;glm-5.1 can do 1,700 rn. autonomous work time may be the most important curve after scaling laws. glm-5.1 will be the first point on that curve that the open-source community can verify with their own hands. hope y&#8217;all like it^^&#8221;<\/p>\n<p>In a market increasingly crowded with fast models, Z.ai is betting on the marathon runner. The company, which listed on the Hong Kong Stock Exchange in early 2026 with a market capitalization of $52.83 billion, is using this release to cement its position as the leading independent developer of large language models in the region.<\/p>\n<h2>Technology: the staircase pattern of optimization<\/h2>\n<p>GLM-5.1s core technological breakthrough isn&#8217;t just its scale, though its 754 billion parameters and 202,752 token context window are formidable, but its ability to avoid the plateau effect seen in previous models. <\/p>\n<p>In traditional agentic workflows, a model typically applies a few familiar techniques for quick initial gains and&#8230;<\/p>\n<p><a href=\"https:\/\/venturebeat.com\/technology\/ai-joins-the-8-hour-work-day-as-glm-ships-5-1-open-source-llm-beating-opus-4\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>AI joins the 8-hour work day as GLM ships 5.1 open source LLM, beating Opus&#8230;<\/p>\n","protected":false},"author":1,"featured_media":232428,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/images.ctfassets.net\/jdtwqhzvc2n1\/77oM8cqy8fLWfF65ejw0eW\/534038847f3f387f4d974ed91e77d77b\/ChatGPT_Image_Apr_7__2026__01_44_40_PM.png?w=800&q=75","fifu_image_alt":"","footnotes":""},"categories":[14],"tags":[20,17],"class_list":["post-232427","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-artificial-intelligence","tag-artificial-intelligence","tag-llm"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/232427"}],"collection":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/comments?post=232427"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/232427\/revisions"}],"predecessor-version":[{"id":232429,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/232427\/revisions\/232429"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/232428"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=232427"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=232427"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=232427"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
