After playing #LumoAI by #Proton in #chess, I decided to try #o4mini by #OpenAI. The result was fairly similar. Very strong opening followed by inexplicably dropping its knight and queen in the middle game. At one point it even argued back after I told it one of the moves was illegal. Wrong but confident, not a very good combination of traits.

[Перевод] Тестируем особенности искусственного интеллекта: o3, GPT-4.1 и o4-mini

Искусственный интеллект в последнее время постоянно радует нас разными новостями и новыми моделями. Команда VK Tech перевела статью со сравнением трех новых моделей — это поможет понять, какую же использовать для каких задач и чем модели по-настоящему отличаются друг от друга. Дальше передаем слово авторам оригинальной статьи.

"For the past two and a half years the feature I’ve most wanted from LLMs is the ability to take on search-based research tasks on my behalf. We saw the first glimpses of this back in early 2023, with Perplexity (first launched December 2022, first prompt leak in January 2023) and then the GPT-4 powered Microsoft Bing (which launched/cratered spectacularly in February 2023). Since then a whole bunch of people have taken a swing at this problem, most notably Google Gemini and ChatGPT Search.

Those 2023-era versions were promising but very disappointing. They had a strong tendency to hallucinate details that weren’t present in the search results, to the point that you couldn’t trust anything they told you.

In this first half of 2025 I think these systems have finally crossed the line into being genuinely useful."

[Перевод] GPT наконец перестал выдумывать факты и действительно понимает, что находит в интернете?

Поисковые возможности языковых моделей наконец перешли от многообещающих демонстраций к реально полезным инструментам. Новые модели o3, o4-mini от OpenAI и обновленный Gemini 2.5 Pro научились выполнять поиск как часть процесса рассуждений перед формированием ответа, что практически исключает галлюцинации. Эти системы могут за считанные секунды проводить исследования, на которые раньше уходили часы работы человека.

🤖 AI | OPENAI
🔴 New Reasoning AIs Hallucinate More

🔸 o3 & o4-mini outperform older models in coding & math — but hallucinate more.
🔸 On PersonQA, o3 hallucinated 33% of answers, o4-mini 48%.
🔸 No clear cause; scaling reasoning may amplify false claims.
🔸 Transluce: o3 fabricates actions like fake code execution.

🚨 OpenAI Week is HERE! 🚨

OpenAI is preparing to launch GPT-4.1 nano, alongside o4-mini and o3. Could this be the open-source model Sam Altman hinted at?

A smaller, more efficient GPT-4 could make AI more accessible, sparking new innovations for developers and researchers. Can't wait to see how this unfolds!

🚨 Update from ChatGPT

o3 and o4-mini will launch before GPT-5 in the next couple of weeks.

Why the change?

🔹 GPT-5 is way better than expected
🔹 Integration's trickier than planned
🔹 Prepping for massive demand
