Fable 5's 18-day ban: Anthropic's share went to GLM

定量分析：Fable 5 禁窗 18 天，Anthropic 的蛋糕被谁吃掉了

Anthropic's Fable 5 was taken offline by US export controls three days after launch, for 18 days. OpenRouter daily token data shows total volume grew from 24T to 32T, but Anthropic's share dropped from 20.7% to 17.6% and its absolute volume shrank. GLM was the biggest winner, jumping from 1.8% to 7.4% share. GLM-5.1 saw a spike on the day GLM-5.2 launched, then collapsed 48 hours later as GLM-5.2 took over. Community sentiment shifted from sympathy for Anthropic to mocking its business strategy. The post notes this only captures API-layer data, not first-party subscriptions, and token volume comparisons overstate GLM's share due to a 10x price gap.

Why it matters: A data-driven attribution of the 18-day Fable 5 ban's competitive impact using OpenRouter daily token data: Anthropic lost 3.1pp share, GLM gained 6.7pp, plus a weird anomaly where GLM-5.1 traffic spiked 4-5x after GLM-5.2 launched. Counterintuitive findings that directly touc...

This piece is worth opening because it uses OpenRouter's daily token data to quantify exactly who ate Anthropic's lunch during the 18-day Fable 5 ban. Total volume grew from 24T to 32T, but Anthropic's absolute volume shrank from 5.95T to 5.63T—losing ground in a growing market.

GLM was the biggest winner, quadrupling its share. A weird detail: GLM-5.1 spiked on the day GLM-5.2 launched, then collapsed 48 hours later as GLM-5.2 took over. Could be agent toolchain auto-fallback routing, could be manual dev switching—the post says there's no log data to tell.

Community sentiment split into two arcs: anger at the government peaked on ban day then faded, while mockery of Anthropic's business strategy heated up from June 14. When Fable 5 returned with automatic fallback to Opus 4.8, a 50% weekly cap, and credits-based billing, the HN redeployment post got just 60 points—brutal compared to the frenzy two weeks earlier.

I'd discount GLM's share numbers a bit. The post itself notes GLM's per-token price is one-tenth of Fable 5's, and its token consumption is around 42k, similar to Opus 4.8. Task-level cost advantage isn't as dramatic as the headline price gap. Token volume comparisons overstate GLM's actual usage share. Also, this is OpenRouter API-layer data only—no first-party subscriptions—so Anthropic's API revenue loss might be smaller than the share numbers suggest.

But the direction is clear: 18 days is enough for devs to test alternatives. GLM-5.2 beat Claude Code on vulnerability discovery F1 in Semgrep's independent security test, and Cline and Kilo Code integrated it on launch day. Reuters quoted Poe Zhao's take, which feels closer to reality: 'partial routing, not overnight replacement.' Devs added GLM-5.2 as a routing option, not a full swap, but that already shifts the landscape.
