cortexso/phi-4-reasoning

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

Each branch supports multiple quantized GGUF versions:

• phi-4-reasoning: q2_k, q3_k_l, q3_k_m, q3_k_s, q4_k_m, q4_k_s, q5_k_m, q5_k_s, q6_k, q8_0
• phi-4-reasoning-plus: q2_k, q3_k_l, q3_k_m, q3_k_s, q4_k_m, q4_k_s, q5_k_m, q5_k_s, q6_k, q8_0
