Hy4 Preview vs Grok Build 0.1 Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
Tencent / Hy4 Preview
proDescription
Tencent's early release of its next Hy model, the successor to Hy3, built for productivity work. Hy4 Preview targets software engineering, office and data work, game development, and science, and Tencent reports its largest generation-over-generation gain to date. It reads text, holds a very large context, and reasons deeply by default, with a faster direct mode. Open weights under an Apache 2.0 license.
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.

Tencent / Hy4 Preview
proLong-Horizon Coding Gains
Tencent reports its biggest gains in long-horizon coding and front-end work, plus an internal blind test of engineering tasks where it edged out several open-model rivals.
Deep Thinking By Default
Reasons deeply by default on math, coding, and analysis, with a direct mode for faster replies. As a preview, it can over-verify its own work and spend longer than needed.
Room For Large Projects
A very large context window for long codebases, reports, and research. Tencent reports clear improvements in long-context understanding over the previous generation.
Documents And Spreadsheets
Tencent highlights document and spreadsheet generation as clear improvements, with training data built alongside office and finance specialists. Suited to reports, outlines, and structured office deliverables.
Finance And Science Work
Built for financial analysis and scientific research alongside coding, using data shaped by domain specialists. It has no native web search, so current data comes through connected tools.
Text Only Input
Reads and writes text. No image, audio, or video input. Screenshots, diagrams, and scanned pages are outside what this model can read, which rules it out for visual work.
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.
