Anthropic and OpenAI roll out cheaper models in first release since call for slowdown

OpenAI and Anthropic released new, more affordable versions of their advanced AI models in quick succession, reflecting a fierce pricing competition between the two companies. Anthropic introduced Claude Opus 5.5, a model that matches the performance of its flagship Fable 5.1 but at 40% lower operational costs. This new model is part of a series, including Sonnet 5.5 and Haiku 5.5, which are expected soon.

Anthropic claims this model is their most efficient and is passing these savings onto their customers through price cuts and increased rate limits.

Meanwhile, OpenAI unveiled GPT-6 Sol and GPT-6 Luna, sibling models to their latest GPT-6 Astra. These models are designed to cater to everyday business needs and come with a 50% reduced API cost compared to a current promotion for GPT-5.6. OpenAI attributes this price reduction to advancements in caching and inference technology.

Both labs are experiencing intense competition, even as they have advocated for a slower development pace of advanced models. This price war could impact their profitability, as noted by economist Ara Kharazian from Ramp. The price reductions are part of broader industry trends where tech companies often lower prices to gain market share, but it might not align with investor expectations for increasingly expensive, high-performing models.

These releases follow a period when both companies publicly advocated for a "pace the frontier" initiative, a move by their CEOs Dario Amodei and Sam Altman. While today's models are not groundbreaking in terms of performance, they indicate a continued push towards enhancing AI capabilities beyond the frontier. The real battleground may be in attracting businesses seeking cost-effective AI solutions, rather than selling the most expensive and powerful models.
