Navigating the AI Landscape: Top 10 Models From the Past 18 Months

2025 models focus heavily on reasoning capabilities, with both OpenAI and Anthropic releasing models that can "think" before responding.
Subscription costs for accessing cutting-edge AI range from free (for open-source models) to $200/month for premium services.
Despite advances, all models still struggle with various limitations, including hallucinations, unrealistic physics, and potential biases.

The AI landscape has evolved at breakneck speed over the past 18 months. Tech giants and ambitious startups alike have released increasingly powerful models, making it challenging to keep track of what's available and which one might best serve your needs.

This article cuts through the noise to highlight the most significant AI models released since 2024.
