What makes GPT-5.6 different
GPT-5.6 is built around Sol, Terra, and Luna: one family tuned for flagship reasoning, balanced cost-performance, and high-volume efficiency. Here is what stands out when you run it inside Doraverse.
Sol, Terra, and Luna in one family
GPT-5.6 spans three tiers: Sol for flagship capability, Terra for strong lower-cost performance, and Luna for efficient high-volume workloads, so you pick the right tier per task instead of one-size-fits-all.
Reasoning controls you can dial in
Set reasoning effort from none through max, plus a Pro mode for quality-first tasks that need planning, verification, and tradeoff analysis rather than a quick draft.
Built for tool-heavy agent work
Programmatic Tool Calling and a multi-agent beta make GPT-5.6 a strong fit for bounded tool-heavy jobs and workflows that split across parallel workstreams.
Token-efficient, cleaner output
GPT-5.6 is tuned to reach frontier results with fewer output tokens, with explicit prompt caching and persisted reasoning for multi-turn work.
