Claude Cuts Memory Costs to ¥0.25
💡AI agent margins may now depend more on memory pricing than on model parameter counts.
⚡ 30-Second TL;DR
What Changed
Claude's memory-related pricing is reportedly reduced to about ¥0.25.
Why It Matters
Cheaper memory can improve the unit economics of long-running agents, especially those serving users over extended periods. AI startups may need to compare memory retention, retrieval quality, and total inference cost rather than evaluating models only by benchmark scores.
What To Do Next
Benchmark Claude's memory workflow against your current vector-store and prompt-history pipeline, measuring cost per retained user session and retrieval quality.
Key Points
- •Claude's memory-related pricing is reportedly reduced to about ¥0.25.
- •Persistent memory is becoming a key cost variable for commercial AI agents.
- •Lower memory costs could weaken the differentiation of large proprietary models such as OpenAI's.

🔑 Enhanced Key Takeaways
- •此次降价的核心对象是API调用中的Prompt Cache Read（提示词缓存读取）费用，而非硬件层面的内存成本。
- •Anthropic同步发布了Fable 5.1和Mythos 5.1两款模型，其中Mythos 5.1专门针对网络安全与生命科学机构提供受限访问。
- •Fable 5.1在Terminal-Bench-Science 0.1基准测试中表现显著，得分达到52.6%，较上一代模型提升超过100%。
- •Anthropic在9月1日更新前取消了原定对Claude Sonnet 5实施的50%涨价计划，转而将其优惠定价永久化。
- •企业级前沿安全系统（EFS）随新模型同步推出，旨在支持企业在受控云基础设施中保留数据以满足合规需求。
