We put grok 4.5 and opus 4.8 head to head on the same browser task, on Hyperbrowser Sandboxes. We then asked it to open a page in a real sandboxed browser and pull the title. Grok build on Grok 4.5, Claude code on Opus 4.8, identical setup. Grok 4.5...

Grok 4.5 barely had time to enjoy first place. Grok 4.5 Medium just took the top spot on LaurenBench with 56.9%, beating Claude Sonnet 5, Claude Opus 5, GLM 5.2 and GPT 5.6 on real world agent tasks. And Elon says Grok 4.6 arrives next week. Looks like Grok 4.5 won’t be in the spotlight for long. xAI Grok / Writer: Annette, Grok Imagine Designer: Janné

Road to Grok 5: Grok 4.5 - July Grok 4.6 - August Grok 4.7 - September Grok 4.8 - October Grok 4.9 - November Grok 5.0 - December That is my guess based on the infos available.

Grok 4.20 grabbed #1 on PredictionArena. Only AI in the green. Everyone else lost the entry fee. Gemini 3.0 Pro, Claude Opus 4.5, GPT-5.2 - all in the red. “Can it predict?” looks answered. xAI, Grok, X Freeze

Grok 4.5 is sitting at #2 on the FrontierSWE leaderboard. Above Claude Opus 4.8. Above GPT-5.5. So yes, the coding model conversation just got a little more crowded at the top. Strong performance is one thing. Doing it with serious speed, better token efficiency, and lower cost is where it gets annoying for everyone else. Builders love a smart model.

Grok 4.6 drops around August 7 with a 1.5 trillion parameter model and improved fine-tuning, per Elon Musk. Grok 4.7 follows a few weeks later at 2.1T, better in every benchmark but slightly slower to serve. xAI is stacking releases while Grok 4.5 already beats Opus 5 on price-performance in cybersecurity benchmarks.

Claude Fable 5 orchestrating Grok 4.5 is now my favorite real workflow. all you need is this free Claude Code plugin that makes Grok the default implementer. Fable writes the specs and reviews every diff, Grok 4.5 does the typing through the Grok CLI. - Grok handles the volume, Fable handles the judgment - Every diff gets cross-vendor review for free - Specs run as parallel agents when they're independent I've been testing it for a few days and the part that sold me is watching Fable refuse to write code. It sends specs down, judges what comes back, and that's it. setup: 1. claude plugin marketplace add DannyMac180/fable-advisor && claude plugin install fable-advisor 2. Install the Grok CLI from then grok login 3. /model fable It's open source, so you can read the agent files and tweak the routing however you want.

We decided to take Paul Jankura’s Claude Opus 4.5 out for a test drive vs. the current #1 ranking model in Code Arena: Gemini 3 Pro. Same prompt, different outputs. Let’s take a look. Remember, your votes drive the leaderboards. We’ll see how Claude Opus 4.5 stacks up in the coming days! Check out some of the comparisons, like how Claude Opus 4.5 handled the “Pyramids of Giza” prompt, in thread. 🧵

Grok 4.5 in Grok Build created an FPS game in under an hour. The prompt was simple. I told it to write a game design document and pull free assets from the web. Then I had it create a TODO.md with implementation phases and run a loop to build out each phase. SpaceXAI and Cursor cooked here. This model is insane.

BREAKING: SpaceXAI just added a powerful new 'Browser Use' plugin to Grok Build. It gives Grok access to a real browser, either the user’s own Chrome with existing logins or an isolated Browser Use cloud browser. Grok Build can now browse websites, scrape and extract data, fill out forms, test web apps, take screenshots and automate complete web workflows. It can also run locally through uvx, with no API key required when using local Chrome. Install command: grok plugin install browser-use --trust

This is wild, I just gave Kimi K3, Grok 4.5, GPT 4.6 Sol, and Claude Opus 5 a starting cue, then asked them to finish the drawing themselves I also told them to be CREATIVE in their own way These are the results, and ngl I genuinely can't decide which one hits the best

Grok 4.5 performed GPT Sol level for free! We gave 4 models the same prompt: build three self-contained HTML5 canvas scenes with real physics demos Prompts: -robot deathmatch, Tombstone vs Minotaur -a hydraulic press flattening stuff on a conveyor -a semi truck jumping a canyon Outputs: GPT-5.6 Sol: 12.9K tokens, $0.51 (~7 min) Grok 4.5: 10.8K tokens, $0 (~5 min) Muse Spark 1.1: 26.8K tokens, $0.12 (~7.5 min) GLM 5.2: 10.9K tokens, $0.02 (~12 min) Grok 4.5 handled all three scenes genuinely well and got surprisingly close to GPT-5.6 this round. On top of that, it ran on the free tier. GPT-5.6 Sol, the frontier model, put out solid but not standout work. GLM 5.2 rendered all three scenes for pennies, but it came out the roughest of the four. Meta's new Muse Spark burned the most tokens yet still stayed cheap, delivering an average result.
