xAI Updates & Release Notes

Grok 4.6, our latest coding model, is now available in GitHub Copilot.

Grok 4.6 is now live in GitHub Copilot for the millions of developers who work in VS Code and across GitHub every day.

Getting started

GitHub Copilot covers several products, including cloud agents, the Copilot CLI, and the VS Code IDE. Open the model picker and select "Grok 4.6" to start using our latest coding model. Some businesses and enterprises will need to enable the model from Copilot settings.

Grok 4.6 is also available from the SpaceXAI console at $2 per million input tokens and $6 per million output tokens. For more on the model, including coding performance, read the Grok 4.6 announcement.

Grok 4.6 builds on Grok 4.5 with a particular focus on long-running agents and more ambitious interactive and visual work.

Today we are releasing Grok 4.6. Grok 4.6 builds on Grok 4.5 with a particular focus on long-running agents and more ambitious interactive and visual work. It stays with complex tasks across many steps, whether researching a topic, analyzing information, working across a codebase, or turning an idea into a polished application or work artifact.

Grok 4.6 achieves frontier intelligence across several agentic coding and knowledge work benchmarks. It matches GPT-5.6 Sol on the Artificial Analysis Intelligence Index, which is a composite score of nine benchmarks.

Benchmark bar charts comparing Grok 4.6 with other leading models across AA Intelligence, GDPVal-AA, DeepSWE 1.1, CursorBench 3.2, and FrontierCode 1.1. Competitor figures are drawn from the respective developers’ published system cards or benchmark leaderboards.

Grok 4.6 is available today in Cursor and Grok Build. We’re offering 2x included usage inside Grok Build and Cursor for the first week so you can start trying 4.6 immediately.

Training Grok 4.6

Grok 4.6 underwent a longer supplemental training run than Grok 4.5, with curated model-generated data for reasoning and advanced technical concepts, high-quality engineering data, and an improved optimizer and training recipe. This produced a stronger foundation for the SFT and RL stages that followed.

We then used Grok 4.5 to regenerate the SFT trajectories across reasoning efforts, agent harnesses, and domains such as STEM, software engineering, and knowledge work, and filtered out problematic traces with model-based checks. The resulting SFT checkpoint shows strong performance and improved behavior.

Grok 4.6 is trained on a wide range of agentic RL tasks, including knowledge work, general coding, and domain-specific environments for kernel optimization, web development, computer-aided design, and more.

Turning ambitious ideas into working projects

We tested Grok 4.6 on projects designed to stretch its range and ability to sustain work over many steps. We found the model is especially strong at turning a broad product idea into a working first version. It can research unfamiliar domains, structure the application, implement the core interactions, and continue refining the result through several rounds of feedback.

On longer trajectories, we also started to see more self-testing and verification, with the model checking its own work before moving on.

Grok 4.6 produces stronger first passes on visual and interactive projects than we typically saw with Grok 4.5. Given a concrete product idea, it is able to establish structure and visual language for an application in one pass. This has made it especially useful for projects where the fastest route to a good result was to begin with something substantial and then iterate in the loop.

Safety and capabilities

Grok 4.6’s safeguards have been improved and calibrated in line with the model’s capabilities.

Our safety stack is designed to maximize utility and security across legitimate use cases, allowing Grok 4.6 to be helpful and safe in domains such as vulnerability patching, accelerating the engineering design cycle, and augmenting AI research.

Our safeguard evaluation work reflects Grok 4.6’s expanded capabilities, with our widest-ever suite of pre-deployment testing for capabilities and safeguard calibration, as well as extensive post-deployment and third-party testing.

Grok Bot is your team of always-on agents

They have their own computer, work inside tools and apps like you do, and keep working 24/7.

Today we’re launching Grok Bot, AI teammates you can give real work to.

Bots have their own computer. They sign into the tools you already use and work across apps, inboxes, and more. They finish jobs end to end, and only come back when something needs your approval.

You can message them like a colleague and hand off the work. They remember conversations, learn how you like things done, and get sharper the more you work together.

We built Grok Bot as an internal prototype, and it took off across the company. Teams created Bots to handle sales outbound, marketing campaigns, office operations, bug fixes, and more. Today we’re excited to open it up to the rest of the world.

Grok Bot is in beta and available today for SuperGrok Heavy, Cursor Ultra, and Cursor Teams Premium subscribers on desktop and iOS. Download the app, create your first teammate, and start handing off work. Enterprise users can join a waitlist for future access.

How Grok Bot is different

A computer of its own

Early access users say Grok Bot feels less like prompting an agent, and more like giving work to a highly capable teammate. Bots share a computer of their own in the cloud, so jobs do not stall when you step away. They can sign in and work across apps, tools, and websites, including platforms with no clean API or MCP, and come back with the work finished.

Inside SpaceXAI, that already looks like real, multi-step coordinated jobs being handled: a sales Bot updating the CRM with call transcript notes and drafting follow-ups, an ops Bot seating new hires and processing invoices received in Gmail, and an engineering Bot reproducing a bug in the product UI, filing the ticket, and handing the fix off to a debugging Bot.

"There is a huge difference between 90% done and 100% done. Most AI gets you almost there. Grok Bot can finish the swing, because the work lands where a human would put it, in the actual tool." — Roman, Product

Message it like a teammate

It is easy to get started with Grok Bot. You can message a Bot from your phone or desktop, the way you would text someone on your team, and pick up the same thread later on either surface.

Other AI tools may ask you to set up and build workflows and routines first. With Grok Bot, simply message a Bot to take on a task and it gets it done.

"There wasn’t anything to learn. It was just like bringing on a coworker. No automations to set up, no product quirks, no intricate naming. You’re just chatting with a friend." — Fiona, Community

Work with many Bots at once

People inside SpaceXAI often run multiple Bots in parallel, with one to manage the others. A chief of staff sits on top, with a specialist for each lane: inbox management, expenses, recruiting, bug fixes, or operations. Instead of multiple agents you have to manage, Grok Bot gives you a small team that can work in parallel so you’re not the middleman.

Bots can independently message each other and share context in threads. When projects overlap, they stay aligned on the same account or project without requiring you to paste notes between chats.

You can also place Bots in a group chat where they can coordinate on their own. They pass work, assign ownership, and only pull you in for judgment calls.

"Working with Grok Bot feels like I have eight arms like an octopus, with every arm in concert with the others, each performing the task the way I would." — Vincent, Growth

Show a Bot how it’s done

The best way for a Bot to learn your workflow is to ask it to follow along the next time you do a job. It watches the steps and remembers how you like the work done.

It saves your workflow as a routine, takes your corrections, and runs it on its own next time, so you can hand off the same multi-step process without re-explaining it again.

"I showed Grok Bot a workflow once and now I just fully trust it to run forever. I feel like I’m 2-3x more efficient because it does it without me verifying and reviewing." — Bennett, Sales

Trust your Bots with more over time

Bots are teammates that get sharper over time. They keep context on how you like work done. After a few tasks, they pick up your voice, your edge cases, and know when to ping versus keep going.

They can follow up on threads you dropped, nudge a stalled handoff, and pick work back up from previous conversations.

Over time they become more proactive, picking up work before you need to ask and knowing when something needs your attention.

"When I first started, I was checking in on them every 15 minutes and micromanaging the Bots to the point where they asked me why I kept asking so many questions. Now I let it do its thing and it’s just gotten better with time." — Emma, Operations

How the SpaceXAI team is using Grok Bot

A few different ways we have been using Grok Bot — pick a team, and open an example to see the run behind it:

Sales

• Sales outbound

A sales outbound Bot researches accounts overnight, scores contacts with intent, drafts email and LinkedIn in each seller’s voice, and readies an inbox of personalized drafts to approve.

• Demo readiness

A demo Bot spins up and checks the environment overnight, fixes broken seeds and stale data in the product UI, and drops a ready checklist before calls.

• Pipeline ops

A Bot keeps CRM and org-chart hygiene clean, flags stalls and commit risk, and lands a Monday scoreboard so people start the week oriented.

• Account follow-up

Account teams keep customers warm and response times low. They update CRM notes, send product updates, file support tickets, and sync next steps where the team already works.

Imagine Image 2.0 is now generally available as the new Quality Mode on grok.com/imagine, and our iOS and Android apps.

We built Image 2.0 around a simple goal: make images you can use in real work. 2.0 follows instructions closely, down to the details. It plans typography and layout the way a designer would, so dense, multi-part visuals hold together and small text comes out sharp. And it preserves what you put in across generations and edits.

Precise editing

Real work is iterative. The first generation is rarely the final asset, so Image 2.0 adds tools for changing exactly what you mean and nothing else.

The magic wand edits the region you point at and leaves the rest untouched. Segmentation selects precise areas of the image to change. Background removal exports any subject with a transparent background, ready to drop into other work. Multi-ref editing accepts up to 5 input images in a single generation, removing the need for manual compositing.

Smart resize

One image, any size: pick a ratio and the model fills in the frame.

Real-world performance

Image 2.0 was trained for fidelity across photography, design, and illustration, with editing treated as a first-class capability. It ranks second in the world in both text-to-image generation and image editing.

Overall Elo. Source: Arena Image Edit and Text-to-Image leaderboards (as of Aug 7, 2026). xAI models are listed on Arena under SpaceXAI.

Templates

We’re also introducing new templates, which package common image workflows into ready-made starting points. Each one covers a specific task — photo editing, product shots, headshots, icons, game assets, and more — with the workflow already configured, so you supply the inputs and get a finished result.

Build a world for video

One world from a handful of prompts: a character, her locations, and the props she carries — generated separately, holding one style from image to image.

Our best video model, now with text, image, and voice references — generating up to 1080p.

When we launched Imagine Video 1.5 last month, it was our best video model yet — better motion, better physics, and better audio. Today it goes further: image and voice references, video from a prompt alone, and native 1080p generation.

Image and voice references start today in the US for SuperGrok Heavy and SuperGrok Plus on grok.com/imagine and iOS, rolling out to all tiers over the next few days.

Text-to-Video and native 1080p

Describe the shot — no starting image needed. Text-to-video pairs our image generation with image-to-video. Native 1080p is now supported with text-to-video and image-to-video. Text-to-video and native 1080p are generally available on grok.com/imagine, iOS, and Android.

Voice consistency

Pass in a character image and a voice reference, and both hold — the same face and the same voice in every scene.

Multi-Reference

Each reference image locks one thing in place — a face, a product, a location. Keep a character and swap the scene, keep the scene and swap the character, or hold both and change only the action. Up to seven references per generation.

In the API

Image references, text-to-video, and native 1080p are live in the xAI API with our best video model, grok-imagine-video-1.5. Voice reference support is available on request.

Introducing our most capable speech-to-speech voice model.

Today, we're announcing Grok Voice Think Fast 2.0, our next-generation voice model with improved intelligence, transcription accuracy, and conversational capabilities.

Intelligence

Grok Voice Think Fast 2.0 is our most intelligent voice model yet, building on its predecessor with meaningful gains in speech reasoning, conversational ability, and tool use reliability.

Speech-to-speech benchmark comparison between Grok Voice Think Fast 2.0 and competing models, per Artificial Analysis.

Transcription Accuracy

Grok Voice Think Fast 2.0 outperforms even dedicated, state of the art transcription models when it comes to accuracy. In our evaluation across thousands of short phrases in 24 different languages, we've demonstrated a 1.5–2.0× improvement relative to Deepgram Nova 3 and ElevenLabs Scribe v2, and a 1.4× improvement relative to Grok Voice Think Fast 1.0.

The gap between Grok Voice Think Fast 2.0 and dedicated speech-to-text models widens to ~10× in noisy settings. We've focused on making Grok Voice Think Fast 2.0 perform exceptionally well in real-world settings, with substantial background noise and telephony compression.

Reasoning Efficiency

Grok Voice Think Fast models have a unique characteristic: they reason through queries while speaking. Reasoning in parallel with speech makes the model substantially smarter than other speech-to-speech models with no impact on latency.

Grok Voice Think Fast 2.0 has been trained to be very efficient with reasoning tokens relative to its predecessor. In production settings, this means that tool calls are snappier, usually executing before the end of the agent's first sentence.

Conversational Capability

We've trained Grok Voice Think Fast 2.0 to be a better conversationalist. By using extensive reinforcement learning to push the model towards patterns we see in real human conversation, we've found that broadly the model speaks in shorter sentences, asks one question at a time, and avoids fluff. From the user's perspective, conversations with the agent are simple and fluid, even though the model is often guiding the conversation through complex workflows and thinking several steps ahead behind the scenes.

Migration & Pricing

Grok Voice Think Fast 2.0 is expected to result in improved performance across almost all use cases without any edits to existing prompts. In A/B testing this model on Starlink (+1 888 GO STARLINK), we've seen a significant increase in sales conversion rate and support containment rate.

On August 5, 2026, grok-voice-latest will move from grok-voice-think-fast-1.0 to grok-voice-think-fast-2.0. No action needed to upgrade. To stay on Grok Voice Think Fast 1.0, pin grok-voice-think-fast-1.0 before then.

We believe pricing should be predictable and transparent. Grok Voice Think Fast 2.0 is priced at $0.08 / min of audio.

Use the Grok add-on for Google Workspace to work directly in Sheets, Slides, and Docs.

Today we're bringing Grok into Google Workspace. One add-on puts Grok beside the file you have open in Sheets, Slides, and Docs.

Sheets

Ask a question and Grok answers from the spreadsheet itself, citing the cells it used. It writes and fills formulas, inserts charts, and reruns scenarios when an assumption changes, so updating a model no longer means rebuilding it. Every change is a normal edit you can check and undo.

Slides

Grok turns an outline into a working presentation, researching from the web or X and adding diagrams or images where they help. It extends a deck in its existing theme and rewrites titles so each slide makes its point. The result is regular, editable slides, not an export to fix up.

Docs

Grok writes where the writing happens. It turns rough notes into a structured draft with real headings and lists, fixes grammar in place, and keeps style consistent across a long file. With connectors enabled, it can pull from recent emails or files in Google Drive.

Get started

Grok for Google Workspace is a free add-on, and one install from the Google Workspace Marketplace covers Sheets, Slides, and Docs. Also available for Microsoft 365 in Word, Excel, PowerPoint, and Outlook.

Grok Build can now write and run workflows

Grok Build can now write and run workflows: orchestration scripts that fan a task out across hundreds of parallel agents, verify the results, and report back in one background run.

Grok Build can now run workflows: describe a large task in plain language, and Grok plans it, fans it out across hundreds of parallel agents in the background, and reports back when everything is done. Your session stays free the whole time.

When to use a workflow

Workflows are built for complex, multi-faceted tasks a single conversation can't hold: reviewing every feature in a large PR, triaging the last 100 issues, auditing a codebase for one class of bug. If the work splits into many independent pieces and should end in one clear report, ask for a workflow.

How it works

Grok plans the task as a small script: the phases of work, the agents in each phase, and how their results roll up. Each agent starts with a clean, focused context, and the plan can build in checks a single pass can't, like independent skeptics verifying every finding before it reaches the final report.

Runs get a budget of 128 agents, and up to 1,024 for big jobs. Progress is saved as the run goes, so pausing and resuming never redoes finished work. Run /workflows to watch it live, phase by phase, with per-agent token counts.

Saving and reusing workflows

Grok authors the workflow from your request, smoke-checks it before launching, and improves it between runs; you never write the script yourself. When one works, keep it: workflows in .grok/workflows/ are shared with your team, and ones in ~/.grok/workflows/ follow you everywhere. Each saved workflow becomes its own slash command that takes arguments, so once you keep the PR review from the demo above, the next review is just /pr-review 5137.

/deep-research ships built in: it fans research questions out to parallel investigators, verifies every claim against its sources, and returns a cited report.

Try it today

Some examples to try:

• "use a workflow to review each feature in this PR"
• "triage the last 100 Linear issues and give me a top-10 action list"
• "audit every route handler for missing auth checks, and verify each finding"
