90% Average Price Drop Since 2023
When GPT-4 launched in March 2023, it cost $60 per 1M tokens. Today, comparable models cost $2.50–$5.00. Budget models like GPT-4o mini ($0.15/$0.60) have made AI accessible to every developer.
Context Windows: 8K → 1M+
Maximum context windows grew from 8K tokens (GPT-3.5) to 1M+ tokens (Gemini, Claude). This enables entirely new use cases — full codebase analysis, long document processing, and multi-turn conversations without memory limits.
Open-Source Models Closed the Gap
Llama 4 Scout ($0.11/$0.34) and DeepSeek V4 Flash ($0.14/$0.28) now compete with proprietary models on many tasks. The cost advantage of open-source inference is driving prices down across the industry.
