Murati’s Thinking Machines releases first AI model for broad use

Thinking Machines Lab, founded by former OpenAI executive Mira Murati, released its first AI model called Inkling, an open-weight model designed for versatility and efficiency across different media. The startup aims to compete with leading AI labs like OpenAI and Anthropic, and has raised $2 billion at a $12 billion valuation. Inkling is not monetized directly; instead, Thinking Machines generates revenue through its developer tool Tinker for fine-tuning AI models.

Thinking Machines Lab is releasing its first AI model, more than a year after former OpenAI executive Mira Murati founded the artificial intelligence startup. The new model, called Inkling, is designed to be versatile and efficient, processing queries across different media while balancing “cost against performance,” the company said on Wednesday. Inkling is also open-weight, meaning developers can download and customize the model without seeing the training data or source code. Thinking Machines said Inkling performs well on various benchmarks compared to similar open-weight offerings. The company said Inkling was trained “for strong performance across the board,” but that “it is not the strongest model available today, closed or open.” Founded last February https://www.bloomberg.com/news/articles/2025-02-18/former-openai-cto-murati-unveils-plans-for-new-ai-startup?accessToken=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzb3VyY2UiOiJTdWJzY3JpYmVyR2lmdGVkQXJ0aWNsZSIsImlhdCI6MTczOTkwMzc2NiwiZXhwIjoxNzQwNTA4NTY2LCJhcnRpY2xlSWQiOiJTUlc2MjlUMEcxS1cwMCIsImJjb25uZWN0SWQiOiIyMTlBRENBMjMyNjA0QTE0QUNBQzlENEY5NjA4N0I5RCJ9.0OvID0ZIuDy0JgomQ2yjxFYDizsQvd5KecXYqxQAPSg by Murati and a cohort of other former OpenAI employees, Thinking Machines is part of a group of so-called AI neolabs attempting to build more advanced artificial intelligence software that can compete with leading labs like OpenAI and Anthropic PBC. Some of these companies, including Thinking Machines, have nabbed substantial sums from investors before releasing any products. Murati’s startup raised $2 billion at a $12 billion valuation last year, and was said https://www.bloomberg.com/news/articles/2025-11-13/murati-s-thinking-machines-in-funding-talks-at-50-billion-value to have been in discussions about a bigger, subsequent round. Several employees have since left her company https://www.bloomberg.com/news/articles/2026-01-15/openai-hires-three-staffers-from-mira-murati-s-ai-startup , joining firms like Meta https://fortune.com/company/facebook/ Platforms Inc. and OpenAI.

Meta, once a leader in open model development, has started to focus more https://www.bloomberg.com/news/articles/2025-12-10/inside-meta-s-pivot-from-open-source-to-money-making-ai-model on closed or proprietary models that customers would pay to use. OpenAI, meanwhile, released a pair of open models https://www.bloomberg.com/news/articles/2025-08-05/openai-releases-open-weight-models-after-deepseek-s-success last year but its product portfolio remains dominated by paid offerings. As businesses and individuals become more conscious of their surging AI spending https://www.bloomberg.com/news/articles/2026-06-18/ai-costs-what-shift-from-flat-rate-to-token-pricing-model-means-for-industry , some are turning to freely available models from China for certain tasks, raising national concerns in the US. Thinking Machines is not aiming to monetize the new model. Currently, the startup generates revenue through its developer tool called Tinker for fine-tuning — or customizing — AI models, which it sells to customers such as hedge fund Bridgewater Associates https://x.com/soumithchintala/status/2072052228605509933 to improve AI performance on financial tasks. Inkling is also part of Murati’s bid to build “interaction models” designed to let people collaborate more naturally with AI. “Our interactions with each other are very rich,” she told Bloomberg https://www.bloomberg.com/news/articles/2026-06-05/openai-would-ve-imploded-if-altman-didn-t-return-ex-cto-says last month. “There’s a lot of information in our interactions – when we’re silent, when we’re thinking, when we’re interrupting one another. Interaction models are able to capture all of these nuances.” Subscribe to Fortune Gulf Brief .
