Many labs used increased thinking to boost benchmark scores and performance. Most of the Chinese models were doing that for a while. Google and Anthropic as well.
Not OpenAI. 5.6 already was much more token efficient than other models and Astra beats Sol in token efficiency by a wide margin.
Edit: Just to make the point: Astra (max) has the 2nd highest score and the third lowest output tokens (among the models shown by AA).
