Overview
Microsoft Research developed and released the Phi-4-reasoning series, a cutting-edge family of reasoning-focused language models optimized for chain-of-thought (CoT), step-by-step problem solving, and high-efficiency inference. These models excel in advanced mathematical reasoning, scientific Q&A, and instruction-following scenarios.
The Phi-4 models introduce extended context lengths, ChatML reasoning templates, and strong performance on benchmark datasets, while maintaining compact sizes that are ideal for memory- and latency-constrained environments.
Variants
Phi-4-reasoning
| No | Variant | Branch | Cortex CLI command |
|---|---|---|---|
| 1 | phi-4-mini-reasoning | 4b | cortex run phi4:4b |
| 2 | phi-4-reasoning | 14b | cortex run phi4:14b |
| 3 | phi-4-reasoning-plus | 14b-plus | cortex run phi4:14b-plus |
