Details
The GPT-5.6 Sol, the flagship model of OpenAI's GPT-5.6 series, is available at a 50% discount via AI Gateway until September 18. This discount applies only when requests are executed directly through the OpenAI provider and covers all token types, tiers, regions, and modes. However, the BYOK (Bring Your Own Key) method, where users use their own API keys, is excluded.
The discount applies equally to all service tiers, Fast mode, cached tokens, and long-context requests. Key pricing benefits are as follows:
- Default: Input $2.50 / Output $15.00 per 1M tokens (previously $5.00 / $30.00)
- Flex: Input $1.25 / Output $7.50 per 1M tokens (previously $2.50 / $15.00)
- Priority (fast mode): Input $5.00 / Output $30.00 per 1M tokens (previously $10.00 / $60.00)
Since the model ID remains unchanged, you can immediately benefit from the discounted rates without modifying existing code. GPT-5.6 Sol performs up to max level reasoning effort to solve difficult problems, supports text, image, and PDF inputs, and provides a long context window.
