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=

Kimi K3刚发布,马斯克称2T新模型下周训完,目标超过Kimi

币界网消息,链上分析师AI姨表示,Kimi K3刚发布,马斯克公开了SpaceX AI下一款大模型的进度。他称,这个2T参数模型将在下周完成初始训练,各方面都优于1.5T参数的Grok 4.5。马斯克预计,新模型可能超过Kimi,同时保持接近Grok 4.5的生成速度和token效率。 Artificial analysis的测试显示,Kimi K3和Grok 4.5的智能指数分别为57和54。两者每项任务成本约为0.94美元和0.31美元。Grok 4.5目前略弱,但成本只有Kimi K3的约三分之一。 马斯克想让2T模型在保持效率的同时,补上能力差距。
