Developer zainhas advises that for most tasks you should simply use GPT-6 Astra at the low reasoning setting.

He notes the model's reasoningeffort scaling behaves very differently from GPT-5.6 Sol, so the payoff curve from cranking up reasoning effort has changed. The practical takeaway: higher effort levels may no longer be worth the cost, which matters for users billed by reasoning usage.
