Thinking Machines' Inkling 2 Small claims top spot among western open-weight models

Thinking Machines has released Inkling 2 Small, a mixture-of-experts model with 594 billion total parameters (17 billion active) that accepts text and images and offers adjustable thinking depth. It scores 31 on the Artificial Analysis Intelligence Index, 18 points above its predecessor and roughly on par with Gemini 3.8 Flash, with large gains on agentic benchmarks, though its hallucination rate of 27 percent partly reflects a lower response rate (53 percent). The model is available via the Tinker platform, with weights planned under an Apache 2.0 license after external safety testing.
