Sep 22, 2026

AI Summary

Anthropic and OpenAI have introduced new AI models aimed at reducing costs for users. OpenAI's GPT-6 family now includes models priced 50% lower than previous versions, while Anthropic's Claude Opus 5.5 is designed to be 40% more cost-efficient than its predecessor.

OpenAI has released new tiers in its GPT-6 family, including GPT-6 Sol and GPT-6 Luna, with API prices reduced by 50% compared to GPT-5.6 promotional pricing.
GPT-6 Sol is intended for complex tasks like coding, while GPT-6 Luna is designed for high-volume tasks such as information extraction and document summarization.
Anthropic launched Claude Opus 5.5, which is a more token-efficient model that costs approximately 40% less to operate than the previous Opus 5.
The releases are the first since Anthropic's CEO Dario Amodei called for a slowdown in AI development amid safety concerns.
The push for more affordable models comes as both companies face competition from cheaper, open-weight alternatives offered by firms like Alibaba and Moonshot AI.
