Sebastian Raschka says GPT-5.6 Luna with higher effort beats costlier model configurations on coding benchmarks

For agentic coding, one can say: - Unless you need Terra Ultra perf, it's always better to use a Luna model with higher effort setting (same or better performance but cheaper). - Forget everything below Sol High, use Luna with higher effort settings here - Forget Sol Extra… Show more

Whomever @OpenAI decided that Ultra was higher than Max needs to take an optimization class. https://twitter.com/rasbt/status/2075573860796436626

The charts don't lie! (I suspect) https://twitter.com/rasbt/status/2075573860796436626

There are only two models. Luna xhigh and Sol high https://twitter.com/ArtificialAnlys/status/2075739292052463646

GPT 5.6 Terra is behind across the entire intelligence-cost curve. i.e. Terra will never be justifiable on either price or performance. Luna and Sol consistently dominate Terra. i.e. at every Terra reasoning level, buyers can choose a Luna or Sol configuration that delivers… Show more
