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.

Characterizing web search behavior of conversational LLM agents across four platforms

arXiv:2609.19244v1 reports the first study of agentic Web search across four conversational platforms (ChatGPT, Claude, Grok, DeepSeek), combining real-world user interactions (in vivo) with controlled API experiments (in vitro). The paper analyzes when agents choose to invoke Web search, their query strategies, domain preferences in returned results, and how they transform results into grounded responses, finding substantial variability across platforms, platform-specific result biases, and some reliance on uncited search results.

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.

Designing Grok Bot: interface for persistent agents

The piece describes how Grok Bot is designed around persistent 'Bots'—each with identity, memory, its own runtime and tools—rather than disposable chat sessions. It explains UI choices (roster, avatars that show state, chats as working interfaces, prompts as Skills or Routines, and Artifacts) intended to support agents that continue work across sessions and act autonomously.
