o3-mini and DeepSeek’s Surprising DNA Match

How did an 80% similarity birthed a more efficient AI After all? We can all agree that the AI Era is evolving at a breakneck speed.

OpenAI just released a new model called o3-mini – think of it as a smaller, faster version of their previous AI models.

What makes it special?

Well, it’s like having a super-smart assistant that’s really good at math, science, and coding, but doesn’t cost as much to use.

The best part?

For the first time ever, even people who use the free version of ChatGPT can try it out!

You just need to click the ‘Reason’ button when you’re writing a message and you’d see something very familiar and sometimes too familiar to the DeepSeek Model that’s out there.

If you’re already paying for ChatGPT Plus or Team, you get to use it even more but we will get it to all the cool details later. And if you’re wondering how good it is, it’s actually performing better than some older models while being 93% cheaper to run.

Pretty neat, right? It’s like they found a way to make a sports car that’s as fast as a Bugatti but uses way less fuel than a Honda.

How does it stack up against open-source alternatives like DeepSeek R1, Qwen, and PHI-4?

The o3-mini model is a lightweight yet highly capable AI designed to optimize reasoning tasks, coding efficiency, and structured outputs.

This is the latest addition to its reasoning model series, now available in both ChatGPT and via API access.

This model is designed to deliver exceptional performance in STEM fields, particularly in science, math, and coding while maintaining low cost and reduced latency.

If you look close you might notice there are some similarities between the o3-mini model and the open source DeepSeek R1 model, especially since many modern language models share common underlying transformer architectures

General Observation Against Competitor Models

While I couldn’t find a single unified benchmark report that directly compares the 03-mini model with Qwen, PhI-4, DeepSeek R1, Claude, and Gemini across every metric yet, here are some general observations and points based on available information from community benchmarks.

Here’s a methodical comparison table of the different AI models and their characteristics:

Model Scale & Architecture	Lightweight, compact architecture with focus on efficiency	Large parameter counts (100M-billions), optimized for nuanced tasks	Large parameter counts, broad language capabilities	Similar transformer traits to O3-mini, less proprietary optimization
Latency & Efficiency	Highly optimized for low latency and cost-efficiency	Higher computational demands, longer response times	Variable performance based on deployment, generally less efficient than O3-mini	Not specified directly
Benchmark Performance	Efficient but may lag in deep reasoning	Strong performance on comprehensive benchmarks (MMLU)	Competitive but variable depending on task	Comparable to O3-mini with task-specific variability
