GPT-6 Sol and Luna now available on AI Gateway

GPT-6 Sol and GPT-6 Luna from OpenAI are now available on AI Gateway.

Both models bring GPT-6 improvements to coding, computer use, and professional work at a lower price than GPT-6 Astra.

• GPT-6 Sol (openai/gpt-6-sol) is designed for complex coding and agent workflows that require sustained investigation.

• GPT-6 Luna (openai/gpt-6-luna) is the lower-cost option for running focused agentic workflows, coding tasks, and other repeatable work at high volume.

Compared with their GPT-5.6 counterparts, both models improve factual reliability, communicate more directly with less jargon, and are less likely to make misleading claims about completed coding work.

To use either model, pass its model ID. The examples below use GPT-6 Sol:

1
import { streamText } from 'ai';
2

3
const result = streamText({
4
  model: 'openai/gpt-6-sol',
5
  prompt:
6
    `Investigate the checkout failures, implement and test a fix,
7
     then summarize the changes and any remaining risks.`,
8
});

Try GPT-6 Sol or GPT-6 Luna in the model playground, or compare the two models.
