OpenAI's guide to choosing between GPT-6 Astra, Sol and Luna

OpenAI is positioning GPT-6 as a tiered model portfolio, giving enterprises a clearer way to align AI capability, latency, and cost to specific workloads rather than using one model for everything. For CIOs and technology leaders, the strategic implication is to treat model selection, reasoning effort, caching, and compaction as operational controls that materially affect unit economics, performance, and scalability in production AI systems. IT organizations will need stronger governance around prompts, skills, monitoring, data controls, and workflow design to reliably deploy AI across coding, research, automation, and structured enterprise tasks.
