xAI announced the Grok Imagine API, offering state-of-the-art video generation across quality, cost, and latency. This represents a new API capability for video generation built on the Grok platform.
Grok 4.1 is now available to all users on grok.com, X, and the iOS and Android apps. It is rolling out immediately in Auto mode and can be selected explicitly as 'Grok 4.1' in the model picker. A fast variant, Grok 4.1 Fast, was also introduced along with Agent Tools API for next-generation tool-calling agents.
Grok 4 is described as the most intelligent model in the world, featuring native tool use and real-time search integration. It is available to SuperGrok and Premium+ subscribers as well as through the xAI API. A new SuperGrok Heavy tier was also introduced with access to Grok 4 Heavy, the most powerful version of Grok 4.
Major capability upgrade. Image generation integrated. Beats Claude 3 Opus and GPT-4o on several benchmarks.
Significant reasoning improvements. Context window expanded to 128K tokens. Better at math and coding tasks.

This release introduces multitasking via async subagents using the /multitask command, allowing parallel processing of requests. It also adds improved worktrees support in the Agents Window for running isolated tasks across different branches, and introduces multi-root workspaces enabling a single agent session to make cross-repo changes spanning frontend, backend, and shared libraries.
Cursor introduced multitasking with async subagents via /multitask command to parallelize requests, improved worktrees experience in the Agents Window for running isolated tasks across branches, and multi-root workspace support allowing a single agent session to target multiple folders for cross-repo changes.
Cursor 3.1 introduces interactive Canvases that allow the AI to respond with visualizations including dashboards and custom interfaces. The Agents Window received a tiled layout for running multiple agents in parallel, and voice input was upgraded with batch STT for higher-quality speech-to-text transcription.
Bugbot can now learn from feedback on pull requests and turn those signals into learned rules that improve future reviews, achieving a 78% resolution rate. MCP server support was added for additional context during code reviews on Teams and Enterprise plans. Additional improvements include a 'Fix All' action, redesigned settings, and improved Bugbot Autofix reliability.
Cursor added 30+ new plugins from partners like Atlassian, Datadog, GitLab, and Hugging Face, enabling cloud agents to read, write, and take actions across more of the user's stack. Previous updates also introduced Automations for always-on agents triggered by schedules or events, JetBrains IDE support via Agent Client Protocol, MCP Apps with interactive UIs, and Bugbot Autofix for automatic PR fixes.
