## AI 摘要

Anthropic不再遵循年度模型发布周期，前沿升级每2-4个月一次。Claude 4于2025年5月发布，Opus 4.1约10周后推出。Fable 5定于2026年6月发布，若保持相似节奏，Fable 5.1可能落在2026年8月或9月。传闻Fable 5.1已完工，下月或见下一代迭代。

## 正文

Anthropic obvioudsly no longer operate on a classic annual model-release cycle.

Major generations may still arrive roughly once a year, but meaningful frontier upgrades now appear every two to four months.

Claude 4 launched in May 2025. Opus 4.1 followed roughly ten weeks later. If Fable 5 follows a similar cadence after its June 2026 release, a potential Fable 5.1 would most likely land around August or September.

It's crazy to think how good Fable 5 is, and that we'll probably get the next iteration next month. Rumor has it Fable 5.1 is already finished. It's hard to imagine what else is in store for us.

Again: we are still so early.
