Mira Murati's Thinking Labs Launches 975B-Parameter Open-Weight AI Model Inkling Amid Fierce Competition From Chinese Labs

Mira Murati's Thinking Labs debuts Inkling, a massive 975-billion-parameter open-weight AI model capable of reasoning across text, images, and audio with a one-million token context window, but it immediately faces stiff competition from Chinese labs like Kimi, whose K3 model boasts 2.8 trillion parameters and already outperforms it on benchmarks.

• Thinking Labs, the AI startup founded by ex-OpenAI CTO Mira Murati, launches its first open-weight model called Inkling, a generalist AI capable of reasoning across text, images, and audio with 975 billion total parameters and a one-million token context window.
• Inkling enters a competitive open-weight AI landscape currently dominated by Chinese labs, with models like GLM 5.2, DeepSeek V4 Pro, and Kimi K2.6 outperforming Inkling on benchmarks, and Kimi K3 just releasing with 2.8 trillion parameters.
• Open-weight models are gaining traction among enterprises prioritizing cost and customization, but experts note that for high-risk fields like legal, medical, and cybersecurity, closed frontier models remain preferable due to stronger safety tooling and more mature deployment ecosystems.
