## 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.
