#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. It is now preserved as a citable public record on Zenodo. zenodo.org/records/23454073 Peer-reviewed paper: "Impact of LLM assistance on physician decision-making: a multi-country randomized controlled trial"npj Digital Medicine, 2026 DOI: 10.1038/s41746-026-03111-5 Preprint: DOI: 10.1101/2025.08.08.25333272 Preprint medrxiv.org/content/10.1101/… Peer reviewed paper : nature.com/articles/s41746-0…
