About Inkling-Small

Inkling-Small is an open-weights 276B Mixture-of-Experts (MoE) multimodal foundation model with 12B active parameters per token developed by Thinking Machine Labs. Trained on 45T multimodal tokens, it supports text, image, and native audio inputs with up to a 1M token context window, variable thinking effort, and sliding-window attention. It achieves near-parity and on certain benchmarks outperforms the 975B flagship Inkling at substantially lower inference latency and footprint.
