Thinking Machines: Inkling (batch)
Inking, from Thinking Machines, is a versatile AI model capable of processing text, images, and audio data, with a context length of 524,288 tokens. It supports reasoning and tools integration but does not offer structured output. This model excels in certain areas, as indicated by its benchmark scores: it shines particularly in coding tasks (with an impressive score of 85.9) but lags in agentic tasks. Given its pricing at $0.5 per million input tokens and $2.025 per million output tokens, Inking is more suitable for users requiring a diverse input modality capability and reasoning abilities, especially those working on complex coding projects. With a blended benchmark score of 70.5 across three independent evaluations, it performs well in practical applications but may not be the best choice for all tasks; its agentic scores suggest limitations in general-purpose agency.
