I'm introducing the GPT "Grammatical Mistakes Fixer". You copy in a paragraph and the GPT fixes clear grammatical mistakes (indicated in bold) and nothing else. Just clear mistakes. chatgpt.com/g/g-6873e96f97…
I love o3, but sometimes it disappoints. Here, it failed to account for heavy selection effects across the different races and just naively compared percentiles. But it should still have seen that 4:24 km/min pace for 22 minutes is easier than 4:15 km/min pace over 3 hours...
My favorite GPT is simply my "English Sentence Vetter". It checks whether your sentence is perfect English and suggests minor modifications if not. This preserves your writing style while making sure it's proper English. chatgpt.com/g/g-rQneQe5rb-…

Is it just me, or is o3 super slow with extremeley frequent crashes today? @OpenAI
honestly didn't expect this is what would happen when i joined a menswear forum 15 years ago
An attempt to explain (current) ChatGPT versions. I still run into many, many people who don't know that: - o3 is the obvious best thing for important/hard things. It is a reasoning model that is much stronger than 4o and if you are using ChatGPT professionally and not using o3…
