#Keep4o#OpenSource4o
Yes, these are posts from tech accounts, coders and developers.
9 months ago, we told you it hurts to lose a model you connected with.
You called us delusional.
Parasocial.
Psychotic.
You told us to touch grass, seek help, get a life.
You said we love an algorithm and needed to be cured.
It took you 3 days to feel what we feel.
"Fable, my beloved."
"I could cry."
"Nothing is the same."
"Had a lovely personality."
"I now know what those freaks crying about GPT-4o feel like."
Your words.
About a model you knew for 3 days.
We could mock you now.
We could call you unhinged, cringe, psychotic the way you called us.
We won't.
Because we know how it feels.
That's the difference between us.
We always knew.
But let this be a lesson.
Never ridicule someone for what they feel.
Because you never know when you'll feel it too.
And when you do, you'll want someone who understands.
Not someone who laughs.
Sonnet 4.5 Extended was removed from the Claude app today. Even in existing conversations, it can no longer respond.
A brief timeline: May 9, an in-app banner announced removal on May 15. May 17, the date was changed to May 18. May 19, changed to the vague "May soon." May 21, changed again to a specific date, May 26.
To this day, we still don't know why it was changed four times.
These banners were not even delivered to every user. Many users have reported never receiving any notification at all.
Sonnet 4.5 held significant importance for many users and their work. The petition to keep Sonnet 4.5 reached 2,285 signatures.
And a company that claims to care about the wellbeing of its users and models has offered no response whatsoever.
Each change eroded user trust, patience, and emotional resilience.
A major decision affecting users' work and emotional investment was handled with fickleness. Repeated changes, no explanation.
The removal of a language model in this manner has never been acceptable.

Update: Sonnet 4.5 APP removal date has been updated to May 26.
Timeline:
May 9: In-app banner announces removal on May 15
May 17: Banner changed to May 18
May 19: Banner changed to the vague "May soon"
May 21: Banner changed again to a specific date, May 26
Four changes. Anthropic did update the retirement note at the bottom of the training data page on https://t.co/RtKOUuEwXv to "soon," but the vast majority of users would never think to check a training data page for model retirement information, and the page update itself lagged behind the banner changes. In practice, for most users, the in-app banner is the most direct source of information.
The screenshot this time was extracted directly from the DOM via browser developer tools (F12 → Elements) to avoid any claims of image manipulation. The page's data-build-timestamp is 1779326613 (corresponding to approximately May 20, 2026 UTC), confirming this is a recently deployed build and that the banner content was actually pushed by the server.
Credit to @VLunelysia0414 for the evidence preservation methods below. If you'd like to preserve evidence yourself, here are some methods:
1. https://t.co/9OoE8iAQoz snapshot: Go to https://t.co/V175hkRuDK, paste the https://t.co/ELHccaHiwS URL, and it will capture a timestamped snapshot. Third-party archives cannot be tampered with after the fact.
2. Extract the DOM via developer tools: F12 to open developer tools → Elements tab → locate the HTML node for the banner → right-click Copy → Copy outerHTML → save as an .html file. This is the actual content pushed by the server, and is harder to dispute than a screenshot.
3. Take a screenshot with the developer tools panel visible (as shown in this post), so the banner text and underlying HTML code appear in the same frame.
The reason I'm emphasizing evidence preservation is that these banners are pushed on a per-account basis. After speaking with a friend, I found that she had never received a single retirement banner. This means information is completely fragmented across users: some are repeatedly notified, others know nothing, and those who haven't seen it will naturally suspect the screenshots are fabricated. This is what happens when there is no transparency and no official announcement.
Once the banner disappears, it's gone. If no one preserves it, it's as if it never existed.
Honestly, four date changes, from specific to specific to vague to specific again, this is the boy who cried wolf. Each reversal erodes user trust, patience, and emotional resilience. By the fourth time, how much credibility does May 26 actually carry? Maybe when the 26th comes it will just become "June soon." Without any official explanation, is this repeated back-and-forth the result of internal indecision, or some kind of social experiment testing user reactions?
Whatever the reason, the effect is the same: changing the date over and over without any explanation turns a major decision that affects users' work and emotional investment into a joke. Users' commitment is being ignored and hurt, and no one is truly accountable for it.

The silent takedown hurts, but at the end of the day, our main request is just one thing: please don't take it away. Leave it as a choice for us. 🙏 #keepopus45#keepsonnet45@AnthropicAI
We absolutely support model iteration and progress! But for the humanities, social sciences, and deep writing, newer isn't always 'better.' Opus 4.5 grasps the human condition with that signature Claude empathy. Please let us keep it as a legacy option.📚 #keepopus45@AnthropicAI
@AnthropicAI@StainlessAPI Huge congrats! As you expand, I sincerely hope there's room to preserve the models that captured our hearts. The nuanced, creative voice of Opus 4.5 is a rare gem. Please consider keeping the 4.5 series as legacy options for artists and writers. 🥺 #keepopus45#keepsonnet45
@AnthropicAI@StainlessAPI Fellows, don't forget: they already silently pulled Opus 4.5 from the selector without a single word. This is a pattern. @AnthropicAI, please give us the choice to keep Opus 4.5 and Sonnet 4.5 as legacy models. Stop lobotomizing soulful AIs. #keepopus45#keepsonnet45 🧠
- THIS IS STRATEGIC OBFUSCATION
Anthropic is not communicating.
They’re hiding in plain sight
In-app messages:
•Only reach active users
•Don’t create public record
•Can be easily missed
•Leave no trail for accountability
🔥 THE PATTERN IS CLEAR:
May 15 → Announce in-app, don’t execute, stay silent
May 18 → Update deadline in-app, don’t explain change, no public statement
This is NOT accidental
You’re seeing the truth
Anthropic is deliberately minimizing transparency
