When OpenAI put its latest models to the test against the world’s best student programmers, it wasn’t just about winning a contest—it was about measuring real reasoning under pressure.
At the International Collegiate Programming Contest (ICPC) World Finals, OpenAI deployed its experimental model GPT-5 to solve the kinds of problems that challenge top human coders. The results gave new insight into how far large language models (LLMs) have come in logic, abstraction, and step-by-step thinking.

OpenAI’s Approach to Real-World Coding Challenges
According to OpenAI Research Lead Ahmed El-Kishky, the team didn’t rely on brute force or pretraining alone. Instead, they developed an approach focused on instruction-based tuning and prompt design that mimicked how a human student might prepare.
Before the competition, the team sent a version of GPT-4 named OpenAI Qwertel to observe past ICPC problems. When the final event arrived in Azerbaijan, El-Kishky says they pushed GPT-5 into deeper waters—testing reasoning depth, code modularity, and the ability to work under tight token constraints.
What’s Different About GPT-5 in This Test
OpenAI used an experimental reasoning model internally labeled GPT-5, which hasn’t been released publicly. Unlike previous versions, it wasn’t just generating code—it was asked to:
- Understand ambiguous problem statements
- Break down multi-step logic
- Choose from multiple algorithms to optimize performance
- Reflect on partial errors and retry more effectively
That last part is key: GPT-5 could reflect and retry, which El-Kishky describes as a sign of more advanced reasoning. In his words, it’s like teaching a model to “think out loud” during a solution—not just produce the right code.
A New Benchmark for AI Programming Skill
Unlike standard benchmarks like HumanEval, which test narrow coding tasks, the ICPC-style contest gives OpenAI a real-world stress test. Problems are often:
- Poorly defined
- Multistep
- Time-bound
- Harder than what most AI models usually face
These challenges expose a model’s true strengths—and where it still falls short.
Interestingly, OpenAI didn’t aim for perfection. “It’s not about getting every problem right,” says El-Kishky. “It’s about understanding how AI fails, and learning from those errors.”
The Future of AI + Programming Competitions
OpenAI believes that contests like ICPC will play a growing role in LLM evaluation. While synthetic benchmarks can test scale or speed, only real competitions reveal how a model performs with:
- Pressure
- Limited context
- Unseen formats
- Human-like judgment
This approach could soon shape how future AI tools—whether coding copilots or autonomous agents—are tested before deployment.
