LLM Price Index Jumps 24% on New OpenAI Tier, While Successors Get Cheaper

The LLM Price Index saw a significant 24.2% increase in September, marking its largest monthly rise and first-ever increase. This surge is primarily attributed to the introduction of OpenAI's new GPT-6 Astra model at a higher price tier, rather than an increase in the cost of existing models. In contrast, successor models launched by various labs, including OpenAI and Anthropic, were priced flat or cheaper than their predecessors. Additionally, both Anthropic and OpenAI reduced their cache prices for certain models, which could significantly impact the costs for applications that frequently resend prompts and history. AI

IMPACT Pricing shifts and new tiers may influence enterprise adoption and cost-optimization strategies for AI applications.
