A mysterious new AI model<\/a> is making the rounds among developers \u2014 and nobody is saying who built it.<\/p>\n

Ox Alpha appeared on OpenRouter on Thursday as a “stealth model” from an anonymous third-party provider. OpenRouter describes it as a “reasoning model designed for coding, sustained agentic work, and production workloads. It is suited for long-horizon software engineering, complex reasoning, and workflows that combine text with visual context.”<\/p>\n

It’s also free.<\/p>\n

OpenCode, an open-source AI coding agent, said on X that Ox Alpha would be free for a week with “near unlimited usage” and that its provider had capacity for 100 trillion tokens per day<\/a>, which is roughly 100 times the number of AI tokens Visa said it uses in an entire month.<\/p>\n

Ox Alpha has already attracted interest from prominent tech figures. Stripe CEO Patrick Collison tried the model and said in a post on X that “it’s very impressive.”<\/p>\n

Early speculation suggests it may be the product of a Chinese AI lab<\/a>. Wccftech, an online tech publication, suggested that the Chinese lab behind GLM-5, Z.ai, as one possibility, noting that the company previously tested GLM-5 anonymously under the name “Pony Alpha” and that developers have identified similarities in Ox Alpha’s tokenizer behavior and responses.<\/p>\n

That speculation comes as Chinese AI labs like Zhipu, DeepSeek, and Moonshot AI increasingly challenge US rivals. Models from those companies have approached the performance of leading American systems at a fraction of the cost and are largely open-source.<\/p>\n

Moonshot’s Kimi K3<\/a>, released in July, is a 2.8 trillion-parameter open-weight model built for coding, reasoning, and agentic tasks that quickly drew attention in Silicon Valley for its performance and lower price.<\/p>\n

Still, the evidence is far from conclusive.<\/p>\n

Wccftech later highlighted a competing analysis suggesting Ox Alpha’s tokenizer could instead point toward Microsoft’s MAI family.<\/p>\n

On Saturday, Andrew Curran, a prominent AI analyst, wrote on X that GLM had been the leading theory on Friday night, but by Saturday morning, “people seem less sure of anything.”<\/p>\n","protected":false},"excerpt":{"rendered":"A mysterious new AI model is making the rounds among developers \u2014 and nobody is saying who built…\n","protected":false},"author":2,"featured_media":651590,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[261],"tags":[291,289,290,275338,2006,275341,61021,275343,18,275340,19,17,24535,8475,275337,5733,224602,60573,4670,82,275339,275342],"class_list":["post-651589","post","type-post","status-publish","format-standard","has-post-thumbnail","category-artificial-intelligence","tag-ai","tag-artificial-intelligence","tag-artificialintelligence","tag-chinese-ai-lab","tag-company","tag-complex-reasoning","tag-developer","tag-early-speculation","tag-eire","tag-glm-5","tag-ie","tag-ireland","tag-moonshot-ai","tag-openrouter","tag-ox-alpha","tag-performance","tag-reasoning-model","tag-saturday","tag-silicon-valley","tag-technology","tag-tokenizer-behavior","tag-wccftech"],"share_on_mastodon":{"url":"","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/651589","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/comments?post=651589"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/651589\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media\/651590"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media?parent=651589"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/categories?post=651589"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/tags?post=651589"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
