GPT-5.6 Luna vs Grok Build 0.1 Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
OpenAI / GPT-5.6 Luna
maxDescription
OpenAI's fastest and cheapest GPT-5.6 model, built for high-volume, latency-sensitive work. Luna handles quick edits, first-pass drafts, and simple pages at a low cost, matching the nano tier of earlier GPT generations. It shares the family's very large context, recent knowledge, and text-and-image input, and supports the same reasoning range and web search, so it is capable well beyond its price.
xAI / Grok Build 0.1
proDescription
xAI's coding model, purpose-built for autonomous software engineering rather than chat. Grok Build 0.1 acts as an engineering agent: it reasons through a problem, writes code, runs your terminal, checks for errors, and fixes its own mistakes in a loop. It reads text and images, always reasons before answering, and natively supports Model Context Protocol. Built for long-horizon coding that runs with little supervision, at a low cost, tuned for agent loops.

Why Use GPT-5.6 Luna and Grok Build 0.1?
Aymo gives you more than access to individual models—it provides a complete multi-model AI workspace designed for productivity.
OpenAI / GPT-5.6 Luna
maxFast Cheap Coding
Built for quick edits, first-pass drafts, and simple pages at high volume. Best on well-scoped, verifiable coding work where speed and low cost matter more than tackling the hardest problems.
Reasoning Effort You Set
Shares the family's full reasoning-effort range, from none up to the highest settings. Runs shallow and fast by default, with room to push harder when a task genuinely needs it.
Room For Long Inputs
The same very large context window as its larger siblings. Big enough to summarise long documents or process large batches in one pass, unusual capacity for a model at this price.
High-Volume Drafting
OpenAI positions it for cost-sensitive, high-volume workloads. Suited to first drafts, quick rewrites, and repetitive text work at scale rather than polished long-form or high-stakes writing.
Web Search And Recent Knowledge
Supports web search as a tool and shares the family's recent knowledge base. Together, those keep it current on live questions despite its budget positioning.
Text And Image Input
Reads text and images in the same prompt, so you can send screenshots or scanned pages alongside your question. Output is text only. Audio and video are not accepted.
xAI / Grok Build 0.1
proAutonomous Engineering Agent
Purpose-built to act as an engineering agent, not a code generator. Refactors across a codebase, invokes tools, runs tests, and iterates through multi-step development tasks, picking up your project conventions as it works.
Reasoning Always On
Every response includes structured reasoning before the final output, and effort is not configurable. Built for deliberate, multi-step work rather than instant answers, so it plans before it acts.
Repository-Scale Context
A large context window, roughly 190,000 words, is sufficient to hold a substantial codebase or a long agent history in a single session. Reporting notes no fixed output cap, so it can refactor large files in one go.
Structured Code Output
Supports structured outputs and a JSON schema, so it slots into agent pipelines and developer tooling. Built to produce parseable, tool-ready output rather than long-form prose.
Native MCP And Tool Use
Natively supports Model Context Protocol, so internal knowledge bases, proprietary APIs, and MCP servers plug in directly. Built to work inside existing developer tooling rather than a closed ecosystem.
Text And Image Input
xAI lists text and image input, with text output. Send source code, diagrams, UI mockups, or error screenshots in the same request. Audio and video are not supported.
