Leak estimate: Astra at ~4.2T parameters, 112 layers, half its layers looped once

I decided against writing an article and revealing how I come to these new estimates. I want to do more analysis on the coming models. my latest central estimate is that GPT-6 Astra is: - 4.2T@120B - around 112 layers - loops 50% of its layers once I also have evidence that GPT-6 Sol and Luna, and Opus 5.5 are NOT looped language models. The leaks about "Astra Minor" suggest a smaller Sol sized looped model coming, that probably slides right into the $20-25 price point.
