GPT-6.1 Terra vs Grok Build 0.1 Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
OpenAI / GPT-6.1 Terra
proDescription
OpenAI's fast, efficient mid-size model in the GPT-6.1 family and the upgrade to GPT-5.6 Terra. OpenAI reports gains over GPT-5.6 Terra in coding, visual reasoning, and factual accuracy, and near-Sol results on MMMU-Pro, at half the per-token price of GPT-6.1 Sol. It reads text and images across a very large context, supports web search, and offers reasoning effort from none to max.
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.

OpenAI / GPT-6.1 Terra
proCoding Above 5.6 Terra
OpenAI reports large gains over GPT-5.6 Terra on software engineering tests, including Terminal-Bench 4.0, which checks how well a model fixes problems from the command line.
Effort None To Max
Reasoning effort runs none, low, medium, high, xhigh, and max, defaulting to medium. Lower levels answer faster, and higher levels spend more time thinking on hard problems.
Room For Whole Projects
A very large context window, with room for a full codebase or a long set of documents in one request. Replies can run up to 128,000 tokens.
Clear, Natural Writing
OpenAI built GPT-6.1 Terra for three things: visual reasoning, precise computer use, and natural writing. That makes it a good fit for everyday drafts, replies, and summaries.
Fewer Factual Errors
Supports web search for current information. OpenAI reports its error rate on a hard factual test fell from 53.6% with GPT-5.6 Terra to 16.7%.
Text And Image Input
OpenAI lists text and image input, with text output. On MMMU-Pro, a visual reasoning test, it nearly matches GPT-6 Astra and GPT-6.1 Sol.
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.
