Summary & Key Takeaways ​

• Mira Murati's Thinking Machines Lab released Inkling, their first open-weights model.
• Inkling is a 975B total parameter, 41B active, multimodal transformer.
• It is Apache-2.0 licensed and trained on 45 trillion tokens.
• A smaller Inkling-Small (276B) model is also in development.
• Positioned as a strong base model for fine-tuning on their Tinker platform.
• Aims to be a competitive contender in the US open-weights ecosystem.

Our Commentary ​

Another significant open-weights model hitting the scene, this time from Mira Murati's lab. We're seeing a real acceleration in the open-source AI space, which is fantastic for innovation. The focus on it being a strong base for fine-tuning is smart; not every model needs to be a frontier giant. I'm a bit wary of the vague training data documentation, though. Transparency is key.
