GPT-5.4 vs Grok Build 0.1 Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
OpenAI / GPT-5.4
maxDescription
OpenAI describes GPT-5.4 as its more affordable model for coding and professional work. It carries OpenAI's top reasoning rating, a million-token context window, and web search. The trade is speed and freshness: it runs at medium speed and its knowledge stops in August 2025. Strong value when the work is hard but not urgent.
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-5.4
maxAffordable Frontier Coding
OpenAI positions this squarely as its cheaper route into complex coding and professional work. Handles large codebases and multi-step engineering tasks with reasoning effort you can push from none up to xhigh when a problem demands it.
Better Reasoning at Lower Price
OpenAI rates its reasoning Highest, the top of the company's own scale, at half the price of its newest frontier model. Reasoning tokens are supported, and effort defaults to none, so you decide when the model thinks hard.
One Million Context Tokens
A 1,050,000-token context window. Load a full codebase, a research corpus, or a large document set and work across all of it in one session. Prompts above 272,000 input tokens are billed at a higher rate.
Extended Professional Writing
Writes up to 128,000 tokens in a single response, enough for long reports, complete documentation sets, and extended technical writing without breaking the job into parts.
Web Search Support
Web search is a supported tool, so it can ground answers in live sources. Its knowledge cutoff is 31 August 2025, which is older than most frontier models, so recent events genuinely need that search rather than merely benefiting from it.
Reads Text and Images
Text and image input, text output. OpenAI's documentation states plainly that audio and video are not supported. File search is supported, so it can work across uploaded documents.
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.
