Base Model Release Sparks Experimentation With API Completions
By

i havent done the work to compare it to peers but i'm just excited that we have a base model and honestly for all the people that complained about the death of the completions API (
@deepfates ? or deepfates adjacent) not enough people are experimenting with weird usages and -

Claude Solves 30% of Expert-Stumping Biological Data Problems
By
–
New on the Science Blog: We gave Claude 99 problems analyzing real biological data and compared its performance against an expert panel. On 23 problems, the experts were stumped. Our most recent models solved roughly 30% of those—and most of the rest.

Gemini 3.1 Pro vs GPT-5.5 Pro: Ethics Impact on AI
By
–
Its a bit frustrating, because Gemini 3.1 Pro is an excellent model and can deliver really good results. But here is GPT-5.5 Pro for comparison. Sadly, it took this assignment very seriously and ethically and thus was no fun at all.

Claude’s measurable strengths: iteration, exploration, filtering
By
–
Claude’s superpower is measurable in output:
speed of iteration, number of paths explored, and how fast bad ideas get filtered out. Same model, different usage completely different power. -
How an LLM changes the way you think with it
By
–
Franchement oui… mais pas que. Réfléchir avant d’agir c’est la base.
Mais avec un LLM, t’es plus juste en train d’exécuter ou réfléchir solo. En vrai tu réfléchis avec lui, Et c’est là que ça change tout. Si t’as une idée floue il sort un truc moyen
Si t’es clair il t’emmène
