Thinking Machines releases Inkling 2 Small, scoring 31 on the Artificial Analysis Intelligence Index
The 594B MoE model with 17B active parameters is on Tinker for inference and fine-tuning with closed weights; full Apache 2.0 weights are planned next week after safety testing, the lab said on 5 November.
Why it matters
Thinking Machines Lab opened its second model generation with Inkling 2 Small, a 594-billion-parameter mixture-of-experts system that activates 17 billion parameters per token and accepts image inputs. The company says the model scores 31 on the Artificial Analysis Intelligence Index and is available now on Tinker for sampling and fine-tuning while weights stay closed. Full Apache 2.0 weights are planned for the following week after external safety testing. Watch whether the open release lands on schedule and how the model ranks once independent harnesses re-run the board.
