Anthropic silently downgraded cache TTL from 1h → 5M on March 6th
Cache TTL appears to have silently regressed from 1h to 5m around early March 2026, causing significant quota and cost inflation Summary Analysis of raw Claude Code session JSONL files spanning Jan...
Has anybody else noticed a pretty significant shift in sentiment when discussing Claude/Codex with other engineers since even just a few months ago? Specifically because of the secret/hidden nature of these changes.
I keep getting the sense that people feel like they have no idea if they are getting the product that they originally paid for, or something much weaker, and this sentiment seems to be constantly spreading. Like when I hear Anthropic mentioned in the past few weeks, it's almost always in some negative context.
Well, off the top of my head:
- Banning OpenClaw users (within their rights, of course, but bad optics)
- Banning 3rd party harnesses in general (ditto)
(claude -p still works on the sub but I get the feeling like if I actually use it, I'll get my Anthropic acct. nuked. Would be great to get some clarity on this. If I invoke it from my Telegram bot, is that an unauthorized 3rd party harness?)
- Lowering reasoning effort (and then showing up here saying "we'll try to make sure the most valuable customers get the non-gimped experience" (paraphrasing slightly xD))
- Massively reduced usage (apparently a bug?) The other day I got 21x more usage spend on the same task for Claude vs Codex.
- Noticed a very sharp drop in response length in the Claude app. Asked Claude about it and it mentioned several things in the system prompt related to reduced reasoning effort, keeping responses as brief as possible, etc.
It's all circumstantial but everything points towards "desperately trying to cut costs".
I love Claude and I won't be switching any time soon (though with the usage limits I'm increasingly using Codex for coding), but it's getting hard to recommend it to friends lately. I told a friend "it was the best option, until about two weeks ago..." Now it's up in the air.

I've used it with a sub a lot. Concurrency of 40 writing descriptions of thousands of images, running for hours on sonnet.
I have a lot of complaints. I've cancelled my $200 subscription and when it runs out in a few days I'll have to find something else.
But claude -p is fine.
... Or it was 2 week ago. Who knows if they've silently throttled it by now?
The other day I read that letting another agent invoke claude -p was considered a violation (i.e. letting OpenClaw delegate to Claude Code).
Not sure how that's enforced though. I was in OpenClaw discord a while ago and enforcement seemed a bit random.
I'll try to find the source, I might have gotten the details mixed up.
