Mistral: Mistral Small 3.1 24B

Mistral Small 3.1 24B from MistralAI is capable of handling text and image inputs within a context length of 128,000 tokens. However, it lacks support for tools, reasoning, or structured output. With its substantial token limits, this model can process extensive queries but falls short in practical applications that require interaction with external tools. For those seeking cost-effective solutions, Mistral Small 3.1 24B might be worth considering, given its blended benchmark score of 26.8 across one independent test. While not the highest scorer and lacking certain functionalities like tool integration or reasoning capabilities, it offers a balance between price (0.351 cents per input token and 0.555 cents per output token) and performance, making it a viable option for specific use cases where these features are not strictly necessary.
