Our take
Content creators and researchers looking for a free, multimodal AI assistant may find Inkling Small suitable. Its 262,144-token context window and vision capabilities allow for tasks such as analysing an image of a complex diagram and summarising its key components, or integrating visual information into longer textual analyses. Unlike alternatives like Meta Muse Spark or Google Gemini Flash, which are primarily positioned as AI video tools, Inkling Small focuses on general-purpose assistant functionality, including a built-in reasoning mode and support for tool/function calling. This makes it ideal for users who need a flexible AI for varied analytical or content generation tasks, particularly those involving both text and images, and who are comfortable with the OpenRouter API. However, prospective users should be aware that its availability and rate limits are dependent on the upstream provider.
