OpenAI and Anthropic have added lower-cost AI models to broaden their offerings across price tiers, potentially reaching more customers while putting pressure on sales of premium products.

OpenAI’s GPT-6 Sol and GPT-6 Luna are priced at the API level 50% below their predecessors.

Anthropic’s new Claude models, including Claude Opus 5.5, are said to cut costs by up to 40% on typical workloads compared with earlier versions.

The shift toward cheaper models could weigh on premium-product revenue, and some market expectations for Anthropic’s valuation have already declined.

Investors will be watching Anthropic’s financial updates and strategic partnerships, along with any impact on premium-model sales and changes in investment by major stakeholders such as Amazon and Google.
