signal brief

OpenAI faces a new competitive threat as its former CTO, Mira Murati, releases an open-weight AI model called Inkling through her startup Thinking Machines Lab. The model, with 975B total parameters and 41B active, is designed for enterprise customization and directly challenges OpenAI's closed, one-size-fits-all approach. Sources report that Thinking Machines argues open models outperform proprietary ones (source 5). This development follows a period of growing enterprise preference for adaptable AI, with Microsoft CEO Satya Nadella recently warning that proprietary models force companies to 'pay twice' (source 5). The release of a frontier open-weight model by a known leader from OpenAI could accelerate enterprise migration away from OpenAI's platform, potentially reducing demand for its API and subscription services.

What the sources said

  • "Former OpenAI CTO does what Altman won't: releases a frontier AI model that's actually open" (source 3: https://www.theregister.com/ai-and-ml/2026/07/16/former-openai-cto-does-what-altman-wont-releases-a-frontier-ai-model-thats-actually-open/5272177)
  • "Inkling is designed to give calibrated answers... and lets users dial 'thinking effort' up or down... uses a third as many tokens as Nvidia's Nemotron 3 Ultra to hit the same coding performance" (source 5: https://techcrunch.com/2026/07/15/thinking-machines-amps-up-its-bet-against-one-size-fits-all-ai-with-its-first-open-model-inkling/)
