Thinking Machines: Inkling Small
The Thinking Machines Inkling Small is designed to process diverse inputs including text, images, and audio, with a context length of 524,288 tokens. It supports reasoning and can interact through tools, making it versatile for complex tasks. While it excels in certain areas like coding (with an impressive AI Index Coding score of 87.4), its agentic capabilities are less developed. This model should be considered by those requiring a multi-modal approach but are mindful of cost; at $0.5 per million input tokens and $1.2 per million output tokens, it offers competitive pricing for its coverage across text, image, and audio inputs. With a blended benchmark score of 69.0 from three independent evaluations, though not the highest, it provides solid performance across key areas.
