GPT-5.6 Sol, the flagship of OpenAI's GPT-5.6 series, is 50% off on AI Gateway through September 18.
GPT-5.6 Sol, the flagship of OpenAI's GPT-5.6 series, is 50% off on Vercel's AI Gateway through September 18. The discount applies only to requests billed through AI Gateway on the OpenAI provider, not BYOK, but it covers every service tier, cached tokens, cache writes, long-context requests, and all regions.
- Default: $2.50 / $15.00 per M tokens (input/output), down from $5.00 / $30.00
- Flex: $1.25 / $7.50 per M tokens, down from $2.50 / $15.00
- Priority (fast mode): $5.00 / $30.00 per M tokens, down from $10.00 / $60.00
The model ID is unchanged, so existing requests to openai/gpt-5.6-sol pick up the discounted rate with no code change. Sol takes a reasoning effort up to max, accepts text, image, and PDF input, and has a long context window. To use it in a coding agent, run vercel ai-gateway coding-agents setup to connect Claude Code, Codex, OpenCode, or Pi, then select openai/gpt-5.6-sol inside the agent; the discount applies there too.
