thinkingmachines/inkling:freeThis is the free OpenRouter endpoint for Thinking Machines Lab's Inkling, a 975B-parameter mixture-of-experts model (41B active, Apache 2.0 license, 1M-token context) released July 2026 as the flagship of the Inkling family and the company's first in-house model. Free access is rate-limited to agentic-harness use with prompt and output logging, making it best suited for evaluating general-purpose reasoning, coding, agentic tool-use, and RAG rather than production workloads.
