Claudia Blaas-Schenner @claudiablaas.bsky.social · 29/06/2026Interesting find that general LLMs do better than coding-specific models when it comes to Fortran. Maybe another reason is this saying: „You start up with English and end up with Fortran.“ I love the colors that your phone is adding to the screen fotos – clear tells for no AI. 040
