OPEN WEIGHT TAKES 71.5% OF TOKENS AND 23% OF SPEND

Summary from the TLDR AI newsletter

Open-weight models now process more than seven in ten gateway tokens and account for nearly one in four dollars. Their share of spend has more than quadrupled since June. Almost one in three teams changed their most-used lab in September, an index record. Jev was the fastest-adopted model in AI Gateway history, but it only accounted for about 0.27% of gateway spend.
