Overview
Inkling is an open-weight multimodal mixture-of-experts model from Thinking Machines Lab, with 41B active parameters out of 975B total. It is designed for general-purpose reasoning, coding, agentic and tool-use systems,...
Our take
For developers building agentic systems or researchers needing to process extensive textual and visual information, Thinking Machines: Inkling offers a free, multimodal foundation. Its 262,144-token context window, combined with vision capabilities and built-in chain-of-thought reasoning, positions it as a strong candidate for complex tasks such as analysing image-rich research papers or orchestrating multi-step automation. Unlike alternatives like Google's Gemini Flash or Meta's Muse Spark, which are categorised as AI video tools, Inkling focuses on general-purpose reasoning and tool-use, making it more akin to a versatile conversational model with programmatic extensions. The model's support for function calling further enhances its utility for agent-style workflows, allowing it to interact with external systems. However, users should be aware that its availability and rate limits are dictated by the upstream provider. This model is ideal for those who require a free, flexible AI assistant capable of handling large inputs and integrating with custom tools, rather than specialised video generation.
