AI Models Outdated in Months

AI models are now becoming obsolete much faster than before, driven by the continuous release of newer versions. Data from Vercel's AI Gateway reveals that the majority of AI token usage is concentrated on models released within the past three months, highlighting rapid technological turnover.

Simultaneously, open-weight AI models are surging in popularity, surpassing closed-model systems. These models offer greater flexibility and affordability, allowing for self-hosting or deployment on cost-effective cloud servers. This trend is significantly impacting the market, with open-weight models accounting for 56% of token volume in September, up from just 13% in April.

The increased adoption of open-weight alternatives is a key factor in the declining token prices. The average price per token has fallen for three consecutive months, most recently by 23.2%. While various factors contribute, the accessibility and cost-effectiveness of open-weight models are primary drivers. Notably, TypeSafe AI's Jev model has seen rapid adoption due to its low token cost, despite its unique input requirements.
