GPT-5
A good performance / EU-hosting balance for a European company.
Overview
GPT-5 unifies the reasoning capabilities of the o-series with the versatility of GPT-4o. It natively handles text, image, audio and code. It's the most-used consumer model worldwide via ChatGPT. French quality is very good but slightly behind Claude.
Skill profile
Three independent measures
What people prefer, what the model can do, what the market uses. Each source has its biases and none is enough on its own: we show them side by side, never blended.
What do these scores mean?
PhD-level science questions (physics, chemistry, biology), with no tool access.
Resolving real GitHub issues under real conditions (SWE-bench Verified).
Competition-level math problems.
General knowledge across dozens of academic subjects.
Python code generation from specifications.
