Claude rate limits and caching controversies erupt after Fable 5.1 launch
After Fable 5.1's launch, users raised concentrated complaints about Claude's rate limits, caching, and subscription benefits: multiple Max heavy users reported abnormally fast quota depletion and suspected a caching bug in the new Claude Code, while official advice to use /compact less was contradicted by subscriber experience; several users consider GPT-5.6 better overall.
Confirmed
- @doodlestein reported abnormal usage stats in Fable 5.1, suspecting a caching bug in the new Claude Code: merely auditing a project exhausted the 5-hour quota of 28 Max 20x accounts—unprecedented, per the user. @peterjliu relayed identical feedback from multiple developers about misleading quota consumption.
- @kimmonismus and @cyruszei both complained that Claude's rate limits make the model nearly unusable and that Fable's auto-continuation feature is buggy; both prefer GPT-5.6 and note subscriptions did not benefit from Fable 5.1's efficiency gains.
- With Fable 5.1 cache prices sharply reduced, officials advised against frequent /compact usage; @dotey's tests showed not compressing underperforms keeping 200k auto-compaction, and cache discounts apply only to API users—not subscribers, whose cache TTL is 1 hour; using /compact after cache expiry raises costs.
Unconfirmed
- The caching bug remains user speculation with no official confirmation or fix from Anthropic; the exact cause of faster quota depletion (pricing change, accounting change, or bug) awaits an official response.
- Claims that efficiency gains did not reach subscriptions are subjective user reports without official data.
Why it matters
- Rate limits plus a suspected caching bug directly hit the availability and cost of high-tier subscriptions like Max 20x, potentially driving away heavy developers.
- The gap between official advice and subscriber reality (short cache TTL, no discount) exposes inconsistent benefits between the API and subscription systems.
