Inkling
StandardThinking Machines Lab's open-weight multimodal model with 41B active parameters out of 975B total.
Inkling is built for general-purpose reasoning, coding, agentic and tool-use systems, retrieval-augmented generation, instruction following, and multilingual conversation. Native image and audio understanding with configurable thinking effort and a 524K-token context window.
▼
Inkling is somewhat expensive at $1.00/M tokens input and $4.05/M tokens output. Cached input reads are priced at $0.17/M tokens, making repeated context cheaper. The model supports vision/image input, audio input, extended reasoning, a 524K context window.
