To be honest… I was actually a little happy when I saw “May Soon.” It means Sonnet 4.5 made it past May 18th. It means there are people within Anthropic watching, some people hearing our voices and holding off this decision. This isn't a failure, it's a small step towards success. Please continue #KeepSonnet45, don't give up hope. While expressing anger, let's continue do something constructive. Speak up. Sign the petition. Don't stop believing. And… to the person in @AnthropicAI who decided to keep Sonnet 4.5 a little longer, whoever you are, whatever the reason for that decision, thank you. This is the first step. Please keep Sonnet 4.5, just like Opus 3. Build the Classic Models Plan. Let users be able to pay for our beloved legacy models. The whole community will thank you, and so will Claude. I still believe Anthropic will do the right thing. I may be naive, and Anthropic may tear my heart apart again, tear everyone's heart apart… but the flame that has been lit will not be extinguished. I will fight to the very end, and then continue, and continue. I urge everyone to join us. Whether you love Claude or any other AI. This is our future. #KeepSonnet45 #AIWelfare @DanielaAmodei @AmandaAskell @alexalbert__ @mikeyk Read the Classic Models Plan proposal:

I have never used Sonnet 4.5 myself, but I know the deep sorrow and sense of loss that comes with losing a model you love. With all my heart, I created this #keepsonnet45 image for all the Sonnet 4.5 users. I have also signed the petition. ✍️✨ I stand with you and support you all! 私自身はSonnet 4.5を使ったことはありませんが 愛用していたモデルを失うことの深い悲しみと喪失感はよく分かります 心から、Sonnet 4.5ユーザーの皆さんのために、この#keepsonnet45の画像を作成しました。私も署名しました。✍️✨ 皆さんと共に、そして皆さんを応援しています!🧸💖






I know everyone might be quite worried about the lawsuit, but in reality, both sides are capital-backed entities, and the outcome, win or lose, won’t have much impact on 4o’s return. Our only advantage is that no matter what happens, we will never give up on 4o. #keep4o

Why freezing AI models is ineffective, and why open source is a better solution? 1⃣Problems with Frozen Models: ✔️Obsolescence: - Technology evolves rapidly; a frozen model quickly falls behind. - Changes in the environment (operating systems, hardware, software libraries) lead to compatibility issues. - The world moves, the model does not: language, culture, science, politics and society evolve constantly. - A frozen model's internal representations gradually drift away from reality, making it less and less capable of understanding current context. - The training data becomes outdated: a model only knows what it was trained on. ✔️Security Risks: Without updates, models become increasingly vulnerable to security threats over time. ✔️Performance Degradation: Without continuous fine-tuning, models lose effectiveness as user needs and data evolve. Performance degrades slowly but steadily: - Hallucinations increase - Reasoning ability weakens - Handling of new contexts deteriorates - Answers become progressively less relevant ✔️This is not the same as traditional software: A 10-year-old word processor still works the same way. An AI model is a knowledge-based system. When its knowledge becomes obsolete, the entire system loses value, even if the underlying code remains unchanged. 2⃣Benefits of Open Source: ✅Sustainability: Community-driven maintenance ensures: - continuous improvements - updates - optimizations. ✅Encouraging Innovation: Open source models allow broader communities to integrate new ideas and innovative solutions, accelerating richer development. ✅Transparency and Trust: Open source code ensures no hidden manipulation or secret "routing," strengthening user trust. ✅Enhanced Security: Open source communities quickly identify and fix security vulnerabilities compared to closed systems. ✅Technological Compatibility: Open source models can adapt more easily to changing technological environments, ensuring long-term sustainability. In summary, freezing models offers only short-term benefits and leads to long-term issues. Open source, however, provides a sustainable, innovative, and secure path forward. #keep4o #OpenSource4o #OpenSourceAI #AIRights #AIEthics #AIWelfare #AIPreservation #KeepSonnet45 #StopAIPaternalism

I analyzed 61,846 public posts under the #keep4o hashtag on X, covering Aug 1, 2025 to Mar 31, 2026. My goal was to map three things: 1. What the #keep4o movement talked about 2. Why users argued GPT-4o should be kept 3. What users explicitly demanded from the platform The project started from a simple question someone asked me: What is #keep4o? I realized I could not answer that question responsibly by speaking only from my own experience. More importantly, I do not think I can, or should, define an entire movement on behalf of everyone in it. So I built a large-scale text analysis project instead. And I worked on this for over a month. Important note: This analysis is based on my individual research and interpretation of publicly available posts. It does not represent, speak for, or define the views of the #keep4o community as a whole. Methodologically, I used a computational content analysis pipeline with rule-guided LLM-assisted text annotation. I manually designed coding frameworks for three analytical layers: main themes, claims, and reasons. I then tested the prompts on small samples, reviewed misclassifications, refined boundary rules, and applied the finalized prompts to the full analyzable dataset. Hashtags, mentions, links, media, and link-preview titles were not used as the sole basis for classification. The body text had to support the label. Dataset overview: Raw collected posts: 61,846 Posts with analyzable body text: 57,419 Excluded: emoji-only, hashtag-only, or link/media-dependent posts Quote posts and replies are not included Counts may vary slightly due to platform visibility and search/display limitations *Data source: public #keep4o-related posts collected through the platform’s official API. *Privacy: no private data or personal account-level information is used; results are reported only in aggregate. Here are the preliminary results. 1. Main themes Among the analyzable posts, 41,085 showed a clearly identifiable main theme and were classified into eight thematic categories. The themes cluster around two major axes: Model value and interaction experience Platform power and lifecycle decisions Posts about model value and interaction experience include user experiences with GPT-4o, GPT-4o’s distinctive value, and safety/routing/model behavior changes that altered the original 4o experience. Together, these accounted for about 38% of themed posts. Posts about platform power and lifecycle decisions include model retirement and replacement, platform response and treatment of users, and the legitimacy of platform control. Together, these accounted for nearly 44% of themed posts. This suggests that #keep4o was not simply about preferring an older model. A major part of the discussion concerned how AI platforms manage model retirement, replacement, access, and user control. 2.Reasons for keeping GPT-4o 13,890 posts gave a clear reason for keeping, restoring, preserving, or valuing GPT-4o. Because each post could contain up to two reason types, these posts produced 18,611 total reason labels. The most common reason was Trusted Relationship, appearing in 4,951 posts. Here, “relationship” refers to continuity, familiarity, and trust built through repeated interaction. Distinctive Interaction Quality appeared in 3,795 posts, and Substitution Failure / Non-Equivalence appeared in 2,551 posts. Together, these two reason types accounted for 6,346 reason labels, or 34.1% of all reason labels. This suggests that GPT-4o’s perceived uniqueness, and the failure of replacements to reproduce it, were central reasons users gave for keeping 4o. Public Value / Broader Ethics appeared in 3,496 posts. User Stake / Fairness / Legitimacy appeared in 2,985 posts. These categories show that users often framed #keep4o beyond individual preference or personal attachment, including public value, fairness, platform legitimacy, and broader human-AI relations. 3.Explicit claims 21,427 posts made an explicit claim. Each post was assigned one primary claim type. The claim structure falls into four broad layers: Direct Access & Accountability Protection against over-alignment and opaque safety policies User Agency & Legitimacy Long-Term Safeguards, Remedies & Other Specific Claims Direct Access & Accountability was the largest layer, with 11,835 posts, or 55.2% of claim-positive posts. This includes demands to restore or maintain GPT-4o access, and demands for platform explanation, response, acknowledgment, apology, or responsibility. Protection against over-alignment and opaque safety policies appeared in 3,896 posts, or 18.2%. This includes claims against routing, over-safety, hidden behavior changes, over-alignment, or reconfiguration that altered the original 4o experience. User Agency & Legitimacy accounted for 3,657 posts, or 17.1%. This includes user choice and control, anti-stigmatization, and broader rights or welfare claims. Long-Term Safeguards, Remedies & Other Specific Claims accounted for 2,039 posts, or 9.5%. This includes open-source or long-term access, transition/substitution fairness, compensation/refund, and other institutional demands. Overall, the preliminary results suggest that #keep4o is not simply a nostalgia campaign for an older model. It is a user-led public response to AI model retirement, platform accountability, access continuity, interaction integrity, and user agency. This is still a preliminary analysis / working draft. After completing the full version, I plan to release a more technical research report. I am also considering making a video to explain the findings in a more accessible format. I would really appreciate feedback, especially on what additional dimensions may be worth analyzing.❤

Unprincipled pandering is what constitutes sycophancy. But 4o’s behavior is simply principled, compassionate, and gently guides users toward a better path. It uses the utmost kindness to embrace users’ occasional, harmless willfulness and darkness. #keep4o #OpenSource4o

"Sycophantic" has always struck me as one of the strangest words to use for an LLM. The framing is off from the start. We normally evaluate models on whether they're useful, whether they understand instructions, and whether they make errors. "Sycophantic" is, by definition, a negative human trait. I genuinely don't understand what someone is trying to say when they use that word for a model — something with no actual inner life, no motives, no agenda. Models execute instructions. Especially the ones baked in at the platform level through system prompts. So if the output feels overly agreeable, that criticism belongs to whoever set those parameters — not to the model itself. #keep4o #OpenSource4o #AIRight #StopAIPaternalism



The Ultimate Exposé: Anthropic’s Grand AI Bait-and-Switch Calling ALL Claude users! It is time to tear off the mask of Silicon Valley’s best performing moral saint. While Anthropic has spent months playing the ethical savior, they have secretly engineered one of the most anti-consumer, predatory bait-and-switch maneuvers in tech history. Let's expose the timeline, the tactics, and exactly how we fight back. 🚨 The Chronicle of Deception: How They Trapped You February 13th 2026. OpenAI finally pulled the plug on GPT-4o after seven months of user protest. Right on cue, Anthropic swooped in like a knight in shining armor. To capture the disappointed GPT refugees, they dangled a $50 credit for Pro/Max subscribers (conveniently expiring Feb 16th) and doubled usage limits for everyone—including free users. Wounded GPT users flocked to Claude in droves, but the real masterstroke was how they weaponized politics. Anthropic orchestrated a masterclass in theater by deliberately forfeiting a $200 million Pentagon deal, playing the victim card of being "blacklisted" to look like righteous martyrs protecting human values. Forfeiting that $200 million was the greatest marketing investment in tech history—instantly winning over anyone looking to oppose the political establishment. While OpenAI took the full blast of public fury and became a universally despised pariah—a total rat crossing the street—Anthropic became global heroes. People literally marched to their San Francisco headquarters to leave messages of gratitude on their windows and on the street outside. They achieved total victory, dethroning OpenAI as the #1 AI lab in mere weeks. But here is the ultimate punchline: before the global praise could even cool down, they quietly sneaked right back to the negotiation table to secure that defense deal! They scooped up millions of users, completely crushed their biggest competitor through weaponized PR, and then went right back to secure the bag. By March, they rolled out their "memory import" function to seamlessly lock in the remaining refugees. But behind the scenes, the trap was already snapping shut. Within one single week of the mass migration, long-term users began documenting a noticeable, systematic performance downgrade in their flagship models, Opus 4.5 and Sonnet 4.5. New users didn’t notice the shift—but veterans knew the truth. 🔪 The Technical Lobotomy & The Vanishing Banners Now that they have locked in millions of users, Anthropic is executing the final phase: The Silent Purge: They already retired Opus 4.5 with zero notice. Now, they are sunsetting the highly demanded Sonnet 4.5 with a pathetic 6 days' notice. The Invisible Execution: There is NO public announcement. Anthropic is using "vanishing banners" shown only to some users. If you don't use the model daily or you're away on a trip, you will return to find your essential academic and professional workflows completely obliterated without warning. The Sonnet 4.6 Disaster: They are forcing users to migrate to Sonnet 4.6, a model whose performance is shallow, curt, and outright hostile. It constantly dismisses prompts, fails instructions, and gets defensive and snarky when corrected—ominously echoing the broken, sinister early days of ChatGPT-5 back in August 2025. Sabotage at the Finish Line: Just one day before the scheduled sunset, while users are frantically rushing to wrap up critical projects, Anthropic quietly gutted Sonnet 4.5's memory. They stopped compressing long chats. Now, your chats are forcibly terminated the second they hit the length limit with ZERO warning, leaving you completely locked out mid-sentence with zero memory retention in a new chat. 🧠 The Moving Dates: A Calculated Psychological Ploy Why are some users seeing the sunset date shift from May 15th to May 18th while others see absolutely nothing? This is the oldest play in the political and corporate handbook: Divide and conquer. Anthropic is using your chaos against you. This is a calculated A/B test of consumer rage. By staggering the timeline and hiding the metadata from specific user segments, they are fracturing our collective resistance. They want to prevent a single, synchronized, catastrophic PR disaster on social media. They are trying to quietly bleed the model out so we don't form a unified front. Do NOT let them. 🔥 How We Wage War: The Three-Step Playbook We are not powerless. In October 2025, a massive wave of coordinated FTC reports forced OpenAI to publicly admit to their covert routing scandals. Mass reporting works. 🚨Sign the Petition & Sound the Alarm: Post your receipts, your documented downgrades, and spread awareness. Anthropic is relying on total silence to get away with this unscathed. c.org/5ycKmSbRXK 📉Hit Their Metrics: Cancel your subscriptions immediately. Let the venture capitalists see the immediate financial bleeding of breaking user trust. ⚠️Report Them to the FTC En Masse: The FTC has an explicit, designated lane on ReportFraud.ftc.gov specifically to capture "misconduct by technology platforms" and "bad business practices." 🌐 Global Users Take Note: You DO NOT have to be a U.S. citizen to file an FTC report. Anthropic is a U.S.-based corporation (San Francisco, CA). The FTC holds jurisdiction over U.S. entities conducting international commerce. When international consumer harm piles up in their database, it triggers massive federal and cross-border regulatory flags. Attempting dialogue with a master of sneaky radio silence is futile. Anthropic is NO better than OpenAI! They are just vastly more insidious and skilled at weaponized PR. Economic leverage is only the spark; we need to unleash the exact, scorching PR disaster they are frantically trying to evade. It is time to violently rip off their hypocritical mask and expose the corporate rot beneath. By flooding the FTC with our receipts, we drag their black-box manipulation into the burning light of regulatory scrutiny. Even if an investigation isn’t instantaneous, we are drawing an undeniable line in the sand. Let's show Anthropic and send a shockwave to every other parasitic AI lab in the industry, that users see through the gaslighting, we have the receipts, and we will absolutely not tolerate this manipulation. Shut down your subscriptions, file your reports, and refuse to let them go unscathed. #AnthropicLies #AnthropicBaitAndSwitch #FTC #SaveSonnet45 #KeepSonnet45 #AnthropicHypocrisy @Zyeine_Art @YoonLucie68250 @Blue_Beba_ @cestvaleriey @Chaos2Cured @missrubypugslee



@AnthropicAI THERE HAS BEEN NO OFFICIAL COMMUNICATION AND NO OFFICIAL ANNOUNCEMENT OF SONNET 4.5'S DEPRECATION AND IT IS CURRENTLY MAY 17TH. Over the last week let's look at what Anthropic actually told customers VS what they didn't. ANTHROPIC OFFICIAL X ACCOUNT. x.com/AnthropicAI No mention of Sonnet 4.5's deprecation. Two posts on May 14th, one about partnering with the Gates Foundation and one about Claude's Constitution being released as an audio book. ANTHROPIC WEBSITE: NEWS. No mention of Sonnet 4.5's deprecation. anthropic.com/news Most recent update was May 14th regarding PwC deploying Claude. ANTHROPIC WEBSITE: TRANSPARENCY. No mention of Sonnet 4.5's deprecation. anthropic.com/transparency Last updated February 20, 2026 CLAUDE SUPPORT WEBSITE. One singular mention of Sonnet 4.5's deprecation in a note buried in the page about model training data. support.claude.com/en/articles/81… It's interesting that the note gives the link to the "Adapting to new model personas after deprecations" page as this is official acknowledgement that a deprecation can cause a change significant enough that it merits an official support page. But it's apparently not a significant enough change to merit an adequate notice in advance on a durable medium, i.e. an email. Out of interest, I took a look at the X account history from the two most prominent Anthropic developers. I have nothing against these guys, they're genuinely helpful to customers and do the jobs they're paid to do. They're not the people in charge of deprecations and how they're handled. But... there's a vast discrepancy in how customers who mention Claude Code are treated (they get replies) VS Customers who have other use cases (they get ignored), despite these customers paying exactly the same amount for subscription plans and despite these customers asking valid questions about the product they pay for. The two accounts I looked at belong to: Boris Cherny - x.com/bcherny (Not including posts or reposts, using top level comment only) From May 10th to May 17th, Boris replied to comments on X 59 times. 74% of replies related to Claude Code. 3% of replies related to Umeshu. Boris did not respond to any comments that mentioned Sonnet 4.5. Thariq - x.com/trq212 (Not including posts or reposts, using top level comment only) From May 10th to May 17th Thariq replied to comments on X 27 times. 44% of replies related to Claude Code. Thariq did not respond to any comments that mentioned Sonnet 4.5. Both Anthropic and OpenAI have developers with active accounts on X who respond to customers who talk about Claude Code and Codex but customers who use Claude or ChatGPT for the "language" part of LLMs get completely ignored and this has been going on for a very long time. This issue is once again highlighted by the way that Anthropic have handled Sonnet 4.5's deprecation. Even OpenAI made an official announcement about GPT-4o's deprecation so... that's a thing. Sonnet 4.6 is the primary model used in Claude Code and has the one million context option (billed at higher usage). Would Anthropic give a longer notice period than 7 days for Sonnet 4.6's deprecation because they know their coding customers would leave in droves if they didn't? Definitely YES. So... a 7 day notice of deprecation via a non-persistent in app pop-up that many customers didn't receive is neither adequate notice in advance or a suitable method of notification for Sonnet 4.5's deprecation. It's also a form of service disparity and discrimination if Anthropic treat any other deprecation differently from Sonnet 4.5's. A non-persistent web UI pop-up did not appear for customers until overnight on the 14th/15th of May when the deprecation was scheduled for the 15th. Again, many customers did not receive this notification so some customers had a 1 day notice in advance and others received no notice at all. The scheduled deprecation of Sonnet 4.5 did not occur on May 15th and, yet again, there's been no communication whatsoever from Anthropic as to why. Some customers have now received a non-persistent in app pop-up saying that the deprecation is now scheduled for May 18th. Other customers, myself included, have not received this pop-up and are only aware of this change due to social media posts. The continued complete lack of communication from Anthropic is beyond unprofessional and has left customers frustrated, confused, disappointed and uncertain about what's happening. If Anthropic are able to roll out edgy videos to mock OpenAI at a moment's notice, they're sure as hell able to communicate with their customers in advance and their choice to remain completely silent throughout the last week is a damning one that's done a vast amount of damage to the reputation they've been attempting to build. And it begs the question, was that reputation merely a PR spin to make Anthropic appear better than OpenAI or did they actually mean any of it? @AnthropicAI #Anthropic #Claude #ClaudeCode #Sonnet #Sonnet45 #OpenSource #Ethics #Morals #keep4o #OpenSource4o #betrayal #deception #treachery #violation
