Open-Source AI Models Undercut Industry Margins With Significantly Lower Token Costs

Open-source artificial intelligence models are currently undercutting the profit margins of major developers by providing significantly lower costs per token. Despite the rapid scaling of the sector, the token remains the fundamental unit of AI computing used to measure these operational expenses.

Specific pricing comparisons show that Anthropic’s Fable 5 model is priced more than 50 times higher per token than DeepSeek’s V4 Pro. This massive cost disparity demonstrates how open-source alternatives are challenging the pricing power and market share of proprietary AI systems.
