IBM: Granite 4.1 8B

The IBM Granite 4.1 8B model is designed for handling text-based tasks with a context length of up to 131,072 tokens and can generate completions up to the same limit. It supports tools integration but lacks reasoning capabilities and structured output options. This model should be considered by users requiring extensive input handling and tool usage but who do not prioritize advanced reasoning or structured outputs. With a blended benchmark score of 10.4 across two independent tests, it performs moderately well; however, the pricing at $0.05 per million input tokens and $0.1 per million output tokens may make it less attractive for cost-sensitive applications, especially given its lower ranking in reasoning benchmarks.
