Fine-tuning LLMs with ethical principles for alignment
By
–
Possible answer: "Huh! We never thought before of conjuring the spirits of Rogers, Kant, Stark and Ged into an LLM. We just finetuned on some text from them about honesty and that solved it permanently. Thanks for the modus ponens, Yud, it was a great modus tollens!"

AI to Add 0.6% Annual GDP Growth Over Next Decade
By
–
They all predict around 0.6% additional growth PER YEAR over the next decade due to AI.
In other words, if GDP growth without AI was going to be 2.5% per year on average, it will now be about 3.1% per year. The compound growth over 10 years will be 36% instead of 28%.
The GDP -
Multimodal LLMs Fail at Car Detection Task Compared to YOLO

I tested Opus 4.7 on a simple car detection task.

→ Took 5 minutes
→ Missed multiple cars
→ Pointed at blank spaces
→ Bounding boxes were even worse
Codex did better (24 cars, accurate points) but still took 3 minutes.
YOLO does the same thing in 30ms.

yea i think it's more about "low rank" here being close to the centroid of a local dense bubble
