Ex-Microsoft exec benchmarks Carbon vs 5.2: Carbon wins at math, still distrusts its coding
MParakhin · x · 2026-11-12
Former Microsoft M365 CPO Mikhail Parakhin shares hands-on impressions comparing Carbon and 5.2: Fable made a big step in math/ML in 5.2 and for the first time he genuinely includes it in the conversation, but Carbon — even at a very constraining "High" reasoning effort — often takes it to school. He still doesn't trust Carbon with coding, though.
