GPT-5.6 Sol, Terra & Luna Are Now Live on Multos
OpenAI's most capable model family just dropped — all three variants are already available on Multos. Here's what they mean for your builds.
Yesterday OpenAI released GPT-5.6 — their most efficient and capable model generation yet. As of this morning, all three variants (Sol, Terra, Luna) are live on Multos. If you're on any paid plan, you can switch to them right now from the model dropdown.
Why This Matters for What You Build
GPT-5.6 Sol scores 80 on the Artificial Analysis Coding Agent Index — the highest of any model — while using less than half the output tokens of its closest competitor. That means your apps get built faster, with fewer retries, and at lower token cost. For Multos users, this translates directly: more complete first-generation outputs, less back-and-forth, better architecture decisions out of the box.
Three Variants, One Pool
Sol is the flagship — complex architecture, multi-file refactoring, system design. Terra matches GPT-5.5 performance at a fraction of the cost — perfect for everyday coding. Luna is the speed demon — fastest responses, lowest multiplier, ideal for quick edits and file operations. All three draw from your single token pool. Auto mode routes between them intelligently, or pick manually with transparent multipliers.
Better Design Output, First Try
OpenAI specifically highlighted GPT-5.6's leap in design judgment — creating polished, functional interfaces with minimal direction. This pairs perfectly with our design system. Multos already enforces premium UX principles: warm colour palettes, proper typography pairing, generous spacing, and restrained accent colours. GPT-5.6's improved taste means our first-generation outputs are now even closer to production-ready — apps that look like shipped products, not AI demos.
98% More Efficient with Batch Mode
GPT-5.6 was designed to get more useful work from every token. Combined with our Batch Mode architecture (8 tools, single batch_execute calls, smart context filtering), you're looking at the most token-efficient AI coding experience available anywhere. A full-stack app that would drain your budget on other platforms barely makes a dent here.
Available Now
GPT-5.6 Sol, Terra, and Luna are live across all plans. Free users get access via Auto mode (which may route to Terra or Luna for efficiency). Paid users can select any variant directly. No action needed — just open Multos and start building.
