AI Trends to Watch in 2025

January 6, 2025

2024 proved AI works. 2025 will determine who uses it well. The novelty has worn off—now it’s about execution. Organizations that built foundations in 2024 will accelerate. Those still experimenting will fall behind.

Here are the trends that will shape AI in 2025.

Model Evolution

Reasoning Models Go Mainstream

reasoning_models:
  current_state:
    - OpenAI o1 demonstrated breakthrough
