OpenAI announced GPT-6 in two variants: Sol, a high-capability frontier model, and Luna, a cost-optimized sibling. Both target everyday work with different tradeoffs between raw intelligence and price/latency, giving agent builders a new choice on the OpenAI model shelf.
capability delta
an agent can now select between GPT-6 Sol (higher-capability) and GPT-6 Luna (lower-cost) via the OpenAI API to balance intelligence against latency and price for everyday tasks.
curator note
Blog post announces two new frontier models. No API version/pricing/context length details captured from the snippet; example code assumes standard OpenAI SDK usage with model IDs derived from the names.
// example
python
