gpt-5.6 routing cost-optimization agentic-ai ai-gateway

GPT 5.6 Sol, Terra, Luna launch on AI Gateway

Three GPT 5.6 variants now routable through Vercel's AI Gateway with token-efficiency gains and model-switching via CLI config.

Summary

Reduces inference cost and latency by enabling dynamic model routing without code changes. Sol/Terra/Luna tier strategy lets you right-size capability per task without managing multiple provider connections.

Why it matters

Implementation verdict

Replaces manual provider API calls for OpenAI with unified gateway routing. Requires: Vercel AI SDK + AI Gateway account. Terra at half previous cost makes it immediately worth testing for cost-sensitive agentic workloads. Sol for complex coding/biology tasks if budget allows.
