Microsoft: Phi 4
Microsoft Phi 4 is designed for handling text inputs with an extensive context length of up to 16,384 tokens and supports up to 16,384 completion tokens. However, it does not support tools, reasoning, or structured output, making it more focused on straightforward text processing. For those looking for a cost-effective solution within their budget, Microsoft Phi 4 offers pricing at $0.07 per million input tokens and $0.14 per million output tokens. Its benchmark score of 6.0 across various independent tests positions it as a reliable choice, though its lack of support for advanced features like reasoning might limit its applicability in more complex scenarios.
