SAN FRANCISCO — OpenAI launched a new mid-range artificial intelligence model Tuesday that costs five times less than its flagship offering, one day after scrapping an upgraded version deemed unreliable.

GPT-6.1 Sol ranks below OpenAI's most powerful model, GPT-6 Astra, released in early September. The company on Monday said it abandoned plans for GPT-6.1 Astra because the model frequently ignored instructions.

The announcement, made at the company's annual developer conference, marks the latest escalation in a price war with rival Anthropic as both firms prepare for initial public offerings.

旧金山——OpenAI周二推出了一款新的中端人工智能模型，其价格是旗舰产品的五分之一。此前一天，该公司放弃了一款被认为不可靠的升级版本。

GPT-6.1 Sol 的性能低于 OpenAI 于 9 月初发布的 GPT-6 Astra，后者是 OpenAI 最强大的模型。该公司周一表示，由于 GPT-6.1 Astra 模型经常忽略指令，因此放弃了该模型的开发计划。

该消息是在公司年度开发者大会上宣布的，标志着与竞争对手 Anthropic 的价格战最新升级，两家公司都在为首次公开募股做准备。
