Sample, evaluate, and post-train Inkling and Inkling-Small, Thinking Machines Lab's models built for Tinker. Use this skill whenever the user mentions Inkling, `thinkingmachines/Inkling`, tml-renderers, `tml_v0` / `TmlV0Renderer`, or thinking/reasoning effort — and whenever they are choosing a model, building training data, running evals, setting up SFT or RL, handling parse errors, or working with audio or image inputs for an Inkling model. Inkling has requirements that differ from other Tinker models (mandatory effort conditioning, its own renderer and tokenizer, a learning rate you calibrate yourself), so load this skill before writing any Inkling code.
