Grok Build adds persistent memory for project sessions

Grok Build now records background markdown notes on conventions, decisions, and durable project facts after each completed turn and reads relevant notes when you return to a project; notes are excluded for secrets, transient task state, and information already in the repository. Notes can be browsed read-only with /memory and are periodically organized into topic files by /dream; the feature applies to new sessions started with /new or a fresh grok.

SpaceXAI open-sources Grok Build coding agent and TUI

SpaceXAI has open-sourced Grok Build, its coding agent and terminal UI; the source is now available on GitHub. The repository exposes the agent loop (context assembly, response parsing, tool-call dispatch), tools for reading/editing/searching code and running commands, the terminal UI, and the extension system (skills, plugins, hooks, MCP servers, subagents), and can be compiled to run fully local-first with a local inference backend via config.toml.

SpaceXAI launches Grok 4.5, a model optimized for coding and agentic tasks

SpaceXAI says it has released Grok 4.5, its newest model trained alongside Cursor and optimized for coding, agentic workflows, and knowledge work. The company reports training across tens of thousands of NVIDIA GB300 GPUs, claims roughly 2× token efficiency versus leading models, 80 TPS serving speed, and priced the model at $2 per million input tokens and $6 per million output tokens; Grok 4.5 is available in Grok Build, Cursor, and via the SpaceXAI console with limited free usage offered.

Grok Build adds background 'workflows' that run tasks across hundreds of parallel agents

Grok Build can now author and run workflows from plain-language requests: it plans multi-phase scripts, fans tasks out to parallel agents (default budget 128 agents, up to 1,024 for large runs), verifies results, saves progress, and reports back when finished. Saved workflows live in .grok/workflows/ or ~/.grok/workflows/, become slash commands, and built-in examples like /deep-research are provided for common tasks such as PR reviews, issue triage, and audits.

Grok Build opens to all users on web, iOS, and Android

Grok Build is now available to all plans and on web, iOS, and Android; it converts natural-language descriptions into live, working apps inside Grok chats and supports publishing to grok.me with custom domains, remixing, GitHub export, secrets, and connectors. The release (previously an Early Beta limited to SuperGrok Heavy in July) also adds faster builds, X integration with rich link banners, generated cover art, and per-app access to Grok models via SpaceXAI APIs.
