Inkling (Thinking Machines)
Open-weights multimodal model, ready to tinker

About Inkling (Thinking Machines)
Inkling is an open-weights multimodal model from Thinking Machines Lab that accepts text, image and audio inputs. Built on a Mixture-of-Experts architecture (975B total / 41B active parameters) with a 1M-token context window, it is a generalist strong at knowledge, math, science and coding. Released with open weights, it is designed to be fine-tuned and adapted for domain-specific applications, agentic coding and multimodal — including audio — processing.
