24 alternatives to Phi-4 Reasoning
Big reasoning power, small models
Phi-4 Reasoning is a pair of open-weight language models in 3.8B and 14B sizes designed to deliver strong reasoning capabilities for mathematics, science, and code tasks. Despite their small size, these models rival… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

Steiner is a series of reasoning models trained on synthetic data using reinforcement learning. These models can explore multiple reasoning paths in an autoregressive manner during inference and autonomously verify or backtrack when necessary, enabling a linear traversal of the implicit search tree.

I built AutoThink, a technique that makes local LLMs reason more efficiently by adaptively allocating computational resources based on query complexity. The core idea: instead of giving every query the same "thinking time," classify queries as HIGH or LOW complexity and allocate thinking tokens accordingly. Complex reasoning gets 70-90% of tokens, simple queries get 20-40%. I also implemented steering vectors derived from Pivotal Token Search (originally from Microsoft's Phi-4 paper) that guide the model's reasoning patterns during generation. These vectors encourage behaviors like numerical…
