AIME 2026 Results are out and GPT is still the best model
The AI benchmark race is heating up, and the underdogs are gaining serious ground.
Deep Dive
The AIME 2026 benchmark results confirm GPT remains the top-performing model. However, the report highlights that open-source alternatives like Kimi 2.5 and DeepSeek 3.2 are rapidly catching up in capability. Crucially, these models offer significant cost advantages, presenting a major challenge to proprietary leaders. This signals a potential shift in the competitive landscape where performance and affordability are becoming key battlegrounds for AI dominance.
Why It Matters
Cheaper, competitive open-source models could democratize access and pressure giants like OpenAI on pricing.
