Design benchmark update pits Sol and Luna against Opus 5.5
The author runs GPT-6 Sol, Luna and Claude Opus 5.5 through the same design benchmark, finding the OpenAI models cheaper, faster and better at layout but less detailed than Opus.
updated my unscientific design bench - Claude Opus 5.5 Low/High/Max - GPT-6 Sol High/Max - GPT-6 Luna High/Max quick thoughts: 1️⃣ OpenAI models are MUCH cheaper (and faster) 2️⃣ Claude looks very... Claude, but has a lot more detail/nuance across every page 3️⃣ Sol is unbeaten for the price/speed and I bet A LOT of people will wake up to the model in the next weeks 4️⃣ Luna is... unreasonably good for its speed and price... it has no business being this good at that cost 5️⃣ LAYOUT-wise I actually prefer the OpenAI models, but they lack much of the detail that Opus 5.5 adds across the board what do you think? https://bench.robinebers.com
