DeepSeek R1 vs OpenAI o1: Do AI Reasoning Models Actually Work?

Large Reasoning Models (LRMs) are supposed to be the next frontier of AI—moving beyond simple pattern matching to true logical reasoning. Companies like DeepSeek and OpenAI claim their latest models are pushing AI into higher-order problem-solving.

But are they actually delivering? Reports and industry benchmarks suggest the results are a mixed bag.

Are These AI Models Really “Reasoning”?

DeepSeek’s R1 model has been making headlines for its strong performance in certain tests. OpenAI’s o1 is also being hailed as a step forward in reasoning. Both claim to handle complex, multi-step problems with improved accuracy.

But according to public benchmarks, these models still struggle with fundamental logic.

Reported Failures on Logical Problems

Take geometry and mathematical proofs. In theory, these models should excel, breaking down problems step by step. But various reported tests suggest issues:

• DeepSeek R1 has shown promise in some structured reasoning tasks, yet still fails on certain multi-step logic problems.
• OpenAI’s o1, while more consistent, has also been observed making avoidable mistakes in logic-heavy challenges.

This raises the question: Are these models genuinely reasoning, or just predicting what “sounds right” based on their training data?

Why LRMs Still Fall Short

Lack of True Logical Processing

Despite their advanced architecture, these models still struggle with basic logic variations. Small tweaks to a problem can cause them to break, suggesting they’re heavily reliant on pre-learned patterns rather than actual reasoning.

“Aha Moments” Are Overhyped

DeepSeek R1 is designed to adjust its approach mid-problem, simulating an “aha moment” like humans do when solving puzzles. But industry tests haven’t consistently proven this works as expected. In many cases, models still fall into rigid, formulaic patterns rather than real breakthrough thinking.

Reinforcement Learning Helps, But Not Enough

DeepSeek R1 uses reinforcement learning to refine its logic, but it still hallucinates false information and struggles with step-by-step verification. This suggests that true reasoning is still out of reach.

What Needs to Change?

For AI reasoning models to become truly reliable, several improvements are needed:

• Better structured reasoning datasets – Training models on more dynamic, evolving logic puzzles could improve their problem-solving ability.
• More focused sub-models – Instead of general-purpose logic models, AI may need specialized reasoning engines for different types of problems.
• Regulatory discussions on AI transparency – With open-source models like DeepSeek R1 gaining traction, governments may start debating regulations to ensure responsible AI deployment.

Final Verdict: Hype or Real Progress?

DeepSeek R1 and OpenAI o1 represent real advancements in AI, but they’re still not at the level of true logical reasoning.

The shift from LLMs to LRMs is an exciting step, but for now, these models are still making errors that expose their weaknesses. Until AI can handle logic with human-like adaptability, the hype around AI “reasoning” should be taken with a grain of salt.

Expect improvements—but don’t expect miracles just yet.
