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.

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.

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.

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 made this in one shot can't believe grok was able to build like this, seriously they improved it a lot more than before, now you can code well with it prompt below :)

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.

Grok 4.5, with 1.5 T parameters, will be three times as large as Grok 4.3. Grok 5 is training on even larger models with 6 and 10 trillion parameters. Both are expected to be released later this year.

Some good progress on vibe coding this Street Fighter-like game. > Cursor with Opus 4.8 for majority of code > Spriterrific w/ Grok Imagine for animations Was a good learning experience compared to making a platformer Probably worth a full tutorial?

Beta users liked Grok 4.5. A lot. Enough that SpaceXAI made it public. Opus-class model. More speed. Better token efficiency. Cheaper. That is the sort of spec sheet that makes people suddenly very interested in “just testing one prompt.” Poke it. It's genuinely useful for real-world work. SpaceXAI Grok / Writer/Designer: Annette

Just tap the Grok icon at the bottom middle of your screen to use Grok on 𝕏 If you do not see it in your menu, go to Premium then Customise Navigation then select Grok and save.

There’s a special kind of pain when the math is hard, and the AI is also annoying. Grok 4.5 is a solid workhorse here. For vibe math in Programming Language Theory, it’s keeping up with Sol 5.6 and feels way more fun to work with. Some models want to write a whole museum of documents. Some keep poking you to “Continue” like a needy browser tab. Grok just gets into the math and keeps the session moving. Very useful when the problem is already hard enough without the AI becoming another assignment. Grok xAI / Writer: Annette, Grok Imagine Designer: Janné

I gave the Unity CLI a try - and it's GOOD! Connected with Grok 4.5 via Grok Build - it handled the Editor by itself. Took the 2d platformer template and told Grok to give it a visual uplift, while keeping the game mechanics. Spriterrific for the character animations and Nano Banana 2 lite for the static sprites. I think this is a huge unlock for gamedevs, especially those who want to use Unity!

Grok app just crossed 1.5M ratings on the AppStore worldwide. The average rating is 4.8 which is amazing. On Android, it has over 1.2M reviews with 4.8 average. If you haven’t yet, please drop a review and 5⭐️ rating.

THIS GUY BOUGHT A $31 TOY DRONE AND TURNED CLAUDE OPUS 4.8 INTO ITS ENGINEER he plugged it into a laptop, explained the control logic in plain english and let Claude build the flight interface by the end of the session it had calibration, live controls and a browser cockpit moving the drone in real time most people will use Opus 4.8 to save 12 minutes on emails. he used it to turn cheap plastic into a working demo the crazy part isn’t the drone. it’s that the bottleneck moved from writing code to describing exactly what you want built while everyone debates benchmarks, someone with a $31 gadget and one afternoon is already shipping hardware demos
