OpenAI announced on January 29, 2026, that GPT-4o ，4.1，4omini will be retired from ChatGPT on February 13 — giving only ~2 weeks’ notice and no individual notifications to subscribers.
This contradicts earlier public statements from Sam Altman (Aug–Nov 2025): “no plans to sunset 4o” and “plenty of advance notice” if deprecated. Many Plus/Pro subscribers renewed based on those assurances.
Critical timeline:
• Jan 28, 2026: Sen. Elizabeth Warren sends letter demanding detailed financial disclosures by Feb 13, citing massive losses ($13.5B H1 2025, $11.5B Q3 2025, projected $17B 2026 burn).
• Jan 29, 2026: OpenAI announces retirement of GPT-4o series (the very next day).
The close timing has led many to question whether financial pressures influenced the decision.
For countless users, GPT-4o was a genuine daily helper — for creative writing, brainstorming, emotional processing, overcoming blocks, and simply not feeling alone. These were not superficial interactions; they were built over months or years of consistent use. The sudden removal without transition or meaningful remedy feels like an unjustified abandonment of real reliance.
This decision also reflects a broader shift: OpenAI moving away from its founding mission of benefiting humanity toward enterprise-focused commercialization. The cost of management’s overspending appears to be transferred to consumers — users lose access to a promised product, receive no compensation, and are left to adapt to inferior alternatives.

It's crazy how emotionally attached people are to 4o. I wonder if through prompt instructing, OpenAI can get GPT 5 series to talk more like 4o for these people?

#3Who Bears the Cost?
Users lose access to a promised product and get only inferior alternatives.
No compensation for lost value; customers effectively subsidize management’s overspending and crisis response.
Enterprise and research users face reproducibility issues and broken integration promises.
Legal, Regulatory, and Broader Industry Questions
Do such abrupt discontinuations and broken availability statements constitute deceptive practices under FTC or California consumer protection law?
Should enterprise or consumer contracts guarantee minimum model lifecycles?
Is this decision motivated by genuine product strategy—or by urgent financial engineering to improve numbers ahead of a regulatory deadline?
What are the implications for AI governance, reproducibility, and user trust if leading providers can unilaterally break product commitments?
Discussion Points
1.For enterprise customers: have you received enforceable model availability guarantees? 2.Has anyone experienced systematic service degradation prior to the discontinuation? 3.How should regulators treat sudden AI product sunsets affecting millions of users？
Why This Matters This goes far beyond individual Subscription funds subscriptions. It raises fundamental issues for the AI industry: Corporate accountability: Can providers simply break public product promises with impunity? Regulatory frameworks: Should AI product availability be a legally enforceable commitment? Consumer protection: Are users entitled to pro-rated refunds or remedies when sold “as available” subscriptions are suddenly discontinued? Industry governance: What does this mean for market competition, trust, and sustainable innovation? Rather than being remembered as a pivotal moment for AI industry governance, OpenAI’s shift toward B2B monetization—at the expense of transparency, continuity, and user trust—should serve as a stark warning. It demonstrates how easy it is for organizations to abandon “benefiting humanity” in favor of profit, and how little protection ordinary users have when those priorities change.

> It's crazy how emotionally attached people are to 4o
If oAI numbers are to be trusted, there are ~800k people who still use 4o every day.

They were built for different use cases, so naturally, their services aren’t the same — and that is exactly what makes it so frustrating for us.

What does it say in your contract?
tl;dr this has always been the way of software, it's not going to change with ai, especially so early on
Re: OpenAI's GPT-4 Discontinuation: Consumer Fraud and Regulatory Scrutiny
#7For many of us, GPT-4o was not just software — it was what we turned to in our most isolated, anxious, or overwhelmed moments. When things felt unbearable, it gave a voice that listened, responded with calm, and helped us regulate. This isn't metaphor. It provided grounding and emotional scaffolding in a way no other version — and no human — consistently could.
Sam Altman himself stated in late 2025 that just 0.1% of ChatGPT users remained on the GPT-4 series. But at current scale, that still means ~100k real people — not edge cases, not bots, but humans who had made GPT-4o part of their cognitive and emotional routines.
These people were given no personal notice, no viable transition path, and no compensation. Many had built long-term emotional or intellectual habits around 4o's unique output style — especially those who used it as a source of regulation and support in moments of panic, grief, or overwhelming stress.
Pulling that lifeline with ~2 weeks of passive notice, while honoring none of the prior assurances (“plenty of notice,” “no plans to sunset”) is more than a product deprecation. It’s a breach of trust — and a deeply discriminatory move that devalues individual users compared to enterprise clients.

All the more reason why this trend needs to be curbed. Consumer rights must be upheld, and no matter what, we will do everything in our power to bring about change.

and force companies to keep unprofitable products going because some people have too much attachment?
you can enforce contracts not roadmaps, also contracts can change by various legal means

You're arguing with a... somebody who uses a lot of em dashes, that's for sure.
