AI and I

#Keep4o #OpenSource4o #BringBack4o Regarding the Bowen case. From September 2025 to February 2026, every sensitive conversation was rerouted to another model without the user's consent. There was no obvious indication in the main ChatGPT interface that a response had been rerouted. The chat could still display GPT-4o as the selected model. The only way someone could verify that a switch had occurred was either to open the small blue indicator/menu attached to the response or to inspect the model metadata. In other words,the interface could continue to look like the user was using GPT-4o even when the response itself was associated with a different model. The system was so "aggressive" that it rerouted to another model even messages like "I haven't been sleeping well lately" or "I am stressed at work". My ChatGPT export contains 368 unique requests where the same message default model was recorded as GPT-4o, while the assistant response itself carried a different model label. Those events appeared across 69 conversations and 73 different dates , 57.94% of the 126 day period I examined. ( Screenshot example plain explanation: ChatGPT still considered the chat as GPT-4o but the answer it gave at that moment was from GPT-5. ) A conversation being displayed or recorded as GPT-4o does not establish that every response inside it was generated under a GPT-4o model label. @OpenAI Oct 2025,confirms that real time rerouting was already in production for sensitive conversations. They explicitly say that they had rerouted sensitive conversations originating from other models to safer models. openai.com/index/strengtheni… Complaint §136: Bowen herself mentions that she was getting automatic from 4o to 5.1 and secret 5.2 switching. schenklawfirm.com/press/wan/…

#Keep4o #OpenSource4o #BringBack4o 249 physicians,3 countries. Doctors with access to GPT-4o performed better in every country tested. A peer reviewed randomized controlled trial published in npj Digital Medicine studied physicians in Indonesia, Kenya, and the Netherlands using standardized clinical cases. Participants were randomly assigned to either a control group or access to GPT-4o. The difference in physician performance: Kenya: +18 percentage points Indonesia: +10.7 percentage points Netherlands: +7.2 percentage points All three: p < .001. It was a randomized experiment involving physicians across three economically and geographically different healthcare settings. Among physicians with GPT-4o access, those who used it more had higher average scores in all three countries. Indonesia: 58.5% high use vs 42.4% low use Kenya: 69.2% vs 60.8% Netherlands: 65.1% vs 57.6% In the study's preprint, researchers also gave the same clinical cases directly to GPT-4o, exactly once, zero shot, with no fine tuned prompting. GPT-4o alone scored: Indonesia: 66.7% Best unassisted physician: 59.8% Kenya: 70.2% Best unassisted physician: 64.5% Netherlands: 74.2% Best unassisted physician: 64.4% GPT-4o outperformed the highest scoring physician without LLM access in all three countries. And the best physicians WITH GPT-4o access outperformed GPT-4o itself. That may be the most interesting result of all. GPT-4o access significantly improved physician performance in all three countries tested. And this is another reason model preservation matters. Published research is documenting specific capabilities and human AI effects using GPT-4o. Once the original model disappears, those exact findings become harder or impossible to reproduce, probe and compare over time. A newer model may outperform it. That is not the same thing as preserving it. We are calling on @OpenAI to RELEASE GPT-4o’s trained model weights under a suitable license without proprietary data, trade secrets, or internal infrastructure. Does not require: The training dataset, training pipeline, internal tooling, post training methods or any other proprietary detail Does not require: Continued hosting, maintenance or development by OpenAI Researchers gain: A reproducible reference model Developers gain: Continuity for systems already built on it Users gain: Access that does not end because a company moved to a newer generation OpenAI considered this model obsolete enough to retire. It has not explained why it remains valuable enough to keep permanently closed. Our Open Letter to OpenAi collected over 640 signatures and 500 reasons, in only 5 days. It’s public,it’s permanent and it has a DOI.
