The Pelican comparison grid for Astra is pretty interesting

The writer generated pelican-on-bicycle SVGs with GPT-6 Astra and compared them in a grid against GPT-5.6 Sol, Terra, and Luna across multiple reasoning levels. Astra used 16 input tokens versus 26 for Sol and Terra, and Astra was about twice Sol’s base rate ($10/million input and $50/million output vs $5/$30). The results show Astra producing consistently more detailed pelicans (though legs are still not always correct below max) while making tier-to-tier pricing less disparate due to lower token usage.
