Thinking Machines’ Inkling leads U.S. open-weight releases with a 41 index score. Independent tests also found high pricing and a 63% hallucination rate, while the full checkpoint needs two terabytes of GPU memory. The open weights leave companies with a harder deployment decision.
Thinking Machines Lab’s first production model has taken the U.S. open-weight lead with a score of 41 on Artificial Analysis’s Intelligence Index. Inkling uses fewer output tokens than several Chinese rivals, yet testing found high prices and a 63% hallucination rate on one knowledge benchmark. Its weights are free, but the full checkpoint needs at least two terabytes of GPU memory. The test begins after the download: which companies can afford to turn open access into a working system?
