About the model

Inkling is a Thinking Machines model that accepts text, images and audio. It supports reasoning on complex tasks and holds a context of up to a million tokens, so it is suited both to long materials and to mixed collections with pictures and recordings. Tool calling (function-calling) is supported, so the model fits into agent scenarios. It follows instructions and keeps the output format. Russian at a medium level.
