OpenAI announced Thursday it will retire several AI models from its flagship ChatGPT chatbot next month, including the popular GPT-4o known for its warm conversational style. The move, detailed in a company blog post, targets GPT-4o, GPT-4.1, GPT-4.1 mini, OpenAI o4-mini, GPT-5 Instant, and GPT-5 Thinking, effective February 13, 2026. This decision comes amid OpenAI’s rapid iteration on newer models like GPT-5.2, which the company says dominates user preferences.
Just 0.1% of ChatGPT users select GPT-4o daily, according to OpenAI, while the vast majority opt for GPT-5.2. Recent enhancements to model personality, customization, and creative ideation have bolstered confidence in the transition. CNBC reported the announcement, noting CEO Sam Altman’s August 2025 X post pledging ‘plenty of notice’ before any GPT-4o retirement—a promise now fulfilled after earlier backlash.
Beloved Model Faces the Axe
“We know that losing access to GPT-4o will feel frustrating for some users, and we didn’t make this decision lightly,” OpenAI stated in its blog. The company emphasized that retiring older models allows focus on high-usage ones: “Retiring models is never easy, but it allows us to focus on improving the models most people use today.” No changes affect OpenAI’s API, where some GPT-4o variants persist for developers.
GPT-4o, launched in May 2024, introduced unified multimodal processing for text, audio, and images, slashing latency and enabling real-time speech. It became a cultural hit for its expressive, human-like interactions, but user data shows waning daily selection. PCMag Middle East highlighted the timing—right before Valentine’s Day—fueling online quips about a ‘chatbot breakup.’
Past Turmoil Shadows the Cut
This isn’t OpenAI’s first GPT-4o rodeo. In August 2025, the company briefly retired it upon GPT-5’s release, prompting uproar from paid users who prized its tone over the new model’s perceived sterility. OpenAI restored access swiftly, with Altman vowing advance warning. Reddit threads from 2025, like one in r/ChatGPT, captured fury: support tickets revealed forced rerouting to GPT-5 despite selections, with users decrying the loss of ‘unique capabilities.’
Earlier API deprecations set precedents. On November 18, 2025, OpenAI notified developers of chatgpt-4o-latest’s February 17, 2026, API sunset, per OpenAI’s deprecations page. VentureBeat noted low API usage for GPT-4o versus GPT-5.1, which offers larger contexts, better reasoning, and lower costs—pushing migrations.
Newer Models Take the Wheel
GPT-5.2, the current heavyweight, powers most interactions with upgrades addressing ‘unnecessary refusals and overly cautious responses.’ OpenAI’s ChatGPT release notes confirm GPT-5.2’s rollout alongside personality tweaks for ‘warmth and enthusiasm.’ Users can now customize ChatGPT’s feel, mitigating some GPT-4o nostalgia.
API users faced similar shifts; chatgpt-4o-latest’s end aligns with cost efficiencies, as GPT-5.1 matches or beats GPT-4o at reduced prices. Developers get three-month transitions, learning from 2025’s GPT-5 rollout chaos that disrupted workflows.
User Loyalty Meets Corporate Pruning
Die-hard fans rallied under #Keep4o in 2025, with Reddit posts lamenting GPT-4o’s ‘stable persona’ and ‘predictable outputs’ absent in successors. One r/ChatGPT user wrote, “Retirement of 4o means retirement of me using OpenAI… I refuse to use GPT-5.” OpenAI support acknowledged disruptions but prioritized rollouts.
Broader context: GPT-4 itself retired from ChatGPT on April 30, 2025, replaced by GPT-4o as default, per Mashable. That shift streamlined offerings amid Altman’s February 2025 admission of model picker confusion. GPT-4o outperformed GPT-4 in writing, coding, and STEM, paving its temporary reign.
Strategic Streamlining Accelerates
OpenAI’s pattern—rapid releases, quick retirements—reflects breakneck AI progress. GPT-5 series, with variants like GPT-5.1-mini and ultimate, boasts higher throughput and reasoning modes. The firm battles GPU shortages while pushing ‘unified intelligence’ sans manual selection.
For enterprises, models remain via API, but ChatGPT’s consumer picker slims down. No GPT-5 retirement timeline yet, though GPT-5 Instant and Thinking join the cull. OpenAI eyes safeguards, learning from real-world use before wide deploys.
Implications for AI’s Fast Track
This purge trims ChatGPT’s menu, easing choice but risking loyalty erosion. With GPT-5.2 dominant, OpenAI bets customization fills gaps. Critics see it as ruthless efficiency; fans, a tone-deaf snub to preferences shaping AI bonds. As Stargate data centers scale with Oracle and SoftBank, model churn underscores compute’s premium.
Developers benchmark GPT-5.1 as drop-in, though latency tweaks loom for pipelines. Consumer access persists via settings toggles like ‘Show additional models,’ per release notes. OpenAI’s transparency—pledged post-2025 backlash—holds, but whispers of fuller GPT-4o API cuts persist into 2026.
