Mira Murati Drops Her First AI Model After Leaving OpenAI—And It's Fully Open Source

Mira Murati left OpenAI in September 2024 to do her own thing. Almost two years later, that exploration shipped. Thinking Machines Lab, the company she founded, released <a href="https://thinkingmachines.ai/news/introducing-inkling/" target="_blank" rel="nofollow external noopener" class="sc-adb616fe-0 bJsyml">>Inkling</a>—a multimodal AI model trained entirely from scratch, with every weight available for free download. When OpenAI's board <a href="https://decrypt.co/206531/sam-altman-out-as-ceo-of-openai-was-not-consistently-candid-with-company-board" target="_blank" class="sc-adb616fe-0 bJsyml" rel="nofollow">fired Sam Altman in November 2023</a>, Murati—then CTO—was named interim CEO. Altman was reinstated five days later, Murati returned to CTO, then left for good roughly 10 months after that. She founded Thinking Machines Lab in February 2025. The company then went quiet—and rich. It raised $2 billion at a $12 billion valuation in July 2025, led by Andreessen Horowitz with Nvidia, Accel, ServiceNow, Cisco, AMD, and Jane Street alongside—one of the largest seed rounds in Silicon Valley history <a href="https://techcrunch.com/2025/07/15/mira-muratis-thinking-machines-lab-is-worth-12b-in-seed-round/" target="_blank" class="sc-adb616fe-0 bJsyml" rel="nofollow">at the time</a>. Reports in November 2025 had the company seeking a new round at a $50 billion valuation. Those talks <a href="https://www.nytimes.com/2026/01/22/technology/thinking-machines-ai-startup-openai.html" target="_blank" class="sc-adb616fe-0 bJsyml" rel="nofollow">collapsed</a> by January 2026. Inkling is a mixture-of-experts model—an architecture where only a portion of the network activates for any given input, keeping inference fast without sacrificing depth. It is a very big model: It has 975 billion total parameters (the internal settings that define how the model processes information), with 41 billion active per task, so forget about running it on your local machine. Being multimodal, this model accepts text, images, and audio, and supports a context window—the amount of text the model can reason over at once—of 1 million tokens, roughly 750,000 words. It was pretrained on 45 trillion tokens spanning text, images, audio, and video. "Our first model, Inkling. Trained from scratch, weights are open, fine-tunable on Tinker today," Murati wrote on X . The fact that it’s trained from scratch means a lot, especially in the open-source community as it could bring a breath of fresh air to Western developers that are wary of China but need to use Asian models for their developments because the top AI companies in the Western world are mostly focused on shipping close-source models. Fine-tuning is the process of retraining an existing model on a specialized dataset to improve its performance on a specific task. Tinker is Thinking Machines' cloud platform built around that use case. The full weights are also on <a href="https://huggingface.co/thinkingmachines/inkling" target=

特朗普社交帖文被包装成付费产品,华尔街机构不付费将慢人一步

币界网消息,特朗普的社交帖文被包装成付费产品,华尔街机构不付费就将“慢人一步”。数周前,推销特朗普Truth Social帖文的邮件开始在华尔街各交易部门流传。一份邮件副本显示,该产品承诺“提供每周7x24小时、亚秒级的特朗普帖文数据,包括周末和盘后时段”。 邮件还敦促收件人“尽快行动”,“你的一些同行已经在部署这款产品了”。特朗普媒体科技集团向高频交易员和对冲基金提供总统言论的即时访问权限,引发了政治和伦理层面的激烈讨论。各机构正在权衡,向一家由特朗普作为最大股东的上市公司支付费用获取他的帖文,究竟意味着什么。 特朗普乐于发布影响市场走势的表态,这意味着任何不愿付费的机构都可能在算法交易中被竞争对手甩在后面。特朗普在第二任期内显然更有底气通过各种业务赚钱,他是特朗普媒体集团的最大股东,持有价值约10亿美元的股份,过去一年还从加密货币项目中赚取了超过10亿美元。
