The Pelican comparison grid for Astra is pretty interesting

In a pelican-riding-bicycle SVG comparison, GPT-6 Astra at its low reasoning level produced better results than any GPT-5.6 Sol model at any level, for 9.55 cents. Astra pelicans from low to xhigh all outperformed the best Sol output. Astra costs roughly twice Sol's price but uses fewer tokens. Astra and Luna both used 16 input tokens versus 26 for Sol and Terra, prompting speculation about their relationship.
