Inkling

Inkling is Thinking Machines Lab's first open-weight foundation model — a 975B-parameter sparse Mixture-of-Experts multimodal transformer (41B active parameters, released July 15, 2026) that reasons over text, images, and audio with a controllable "thinking effort" dial. Built for general-purpose reasoning, coding, and agentic/tool-use workloads, it delivers broad, balanced capability with strong open-weights standing (e.g., #1 US open-weights model on Artificial Analysis) at ~210 tokens/sec hosted throughput.
