GPT-6 Sol and Luna offer GPT-5.6-level models at half the cost, one user says
A user says Sol and Luna deliver GPT-5.6-level capability at half the cost, and suggests Astra for planning, Sol for implementation, and Luna for simple tasks.
I see people missing the point with the GPT-6 Sol and Luna models. We got GPT-5.6 level models at 50% of the cost. They don't need to be super intelligent, just not draining your usage. Astra for planning and orchestration, GPT-6 Sol for the implementation, then review the code with Astra. Anything super basic will be covered by Luna. I used to be the type of person who'd just default to a single model, but the past couple of horrific weeks with Astra draining all of my usage and resets made me think and now it takes more time to switch models, but it'll save your usage. OpenAI still needs to introduce a $500/m plan for the super heavy power users who want to main Astra without burning 7 days of usage in a day.
