According to CoinMeta, the biggest concern has emerged for Anthropic IPO: the models are becoming cheaper and cheaper to purchase. OpenAI CFO Sarah Friar indicates that after GPT-5.6 and Luna saw a 80% price reduction at the end of July, their usage increased tenfold. Currently, the price of API is 0.20 USD per million token inputs, with an output of 1.20 USD. In mid-August, the usage of Luna on OpenRouter had already surpassed the combined total of Anthropic Opus and Sonnet by two times. OpenAI also offered a 50% discount through OpenRouter for Luna and Terra, with the actual price once dropping to 1/10 of the original price. Anthropic has begun to reduce usage costs, and the newly released Fable has cut the cache read fee by 75%. It is estimated that the bills for ordinary workloads can be reduced by 25%, and for tasks that use agent extensively, the reduction can be up to 45%. The company's annualized revenue operating rate at the end of July exceeded 65 billion USD, and the prospectus is expected to be made public this month.
