@leonbi100 Now if only you could fix the app not to lose voice recordings… It’s super frustrating talking for like 5 minutes and then the transcription just errors out ands disappears.

We trained 4.3 using first principles listening to real world feedback. Stay tuned for the big boy runs.
Artificial Analysis@ArtificialAnlys
xAI has launched Grok 4.3, achieving 53 on the Artificial Analysis Intelligence Index with improved agentic performance, ~40% lower input price, and ~60% lower output price than Grok 4.20 The release of Grok 4.3 places @xAI just above Muse Spark and Claude Sonnet 4.6 on the Intelligence Index, and a 4 points ahead of the latest version of Grok 4.20. Grok 4.3 improves its Artificial Analysis Intelligence Index score while reducing cost to run the benchmark suite. Key Takeaways: ➤ Grok 4.3 improves on cost-per-intelligence relative to Grok 4.20 0309 v2: it scores higher on the Intelligence Index while costing less to run the full benchmark suite. Grok 4.3 costs $395 to run the Artificial Analysis Intelligence Index, around 20% lower than Grok 4.20 0309 v2, despite using more output tokens. This makes it one of the lower-cost models at its intelligence level ➤ Large increase in real world agentic task performance: The largest single benchmark improvement is on GDPval-AA, where Grok 4.3 scores an ELO of 1500, up 321 points from Grok 4.20 0309 v2’s score of 1179 Grok 4.3, surpassing Gemini 3.1 Pro Preview, Muse Spark, Gpt-5.4 mini (xhigh), and Kimi K2.5. Grok 4.3 narrows the gap to the leading model on GDPval-AA, but still trails GPT-5.5 (xhigh) by 276 Elo points, with an expected win rate of ~17% against GPT-5.5 (xhigh) under the standard Elo formula ➤ Grok 4.3’s performs strongly on instruction following and agentic customer support tasks. It gains 5 points on 𝜏²-Bench Telecom to reach 98%, in line with GLM-5.1. Grok 4.3 maintains an 81% IFBench score from Grok 4.20 0309 v2 ➤ Gains 8 points on AA-Omniscience Accuracy, but at the cost of lower AA-Omniscience Non-Hallucination Rate of 8 points, so Grok 4.20 0309 v2 still leads AA-Omniscience Non-Hallucination Rate, followed by MiMo-V2.5-Pro, in line with Grok 4.3 Congratulations to @xAI and @elonmusk on the impressive release!

xAI needs to deliver Grok Build to deliver us from Anthropic's bullshit.

Today, at the eleventh hour, Elon lodged a court filing pretending to change his tune about attacking the nonprofit OpenAI Foundation.
The truth is that this case has always been about Elon generating more power and more money for what he wants. Having increasingly realized that his attempt to damage the nonprofit OpenAI Foundation rests on a baseless legal case, Elon is once again trying to change the narrative and save face as the trial approaches. His lawsuit remains nothing more than a harassment campaign that's driven by ego, jealousy and a desire to slow down a competitor.

@Angaisb_ I have a prompt that it should always reason with logic and it didn’t fall for it 💪

This is what I mean when I say GPT-5.2 (and every Instant model since GPT-5) feels small

@ycombinator @ycombinator Co-founder matching isn't working. Almost a month waiting to have my profile approved to be visible. Sent an email, no reply. Kinda disappointing.

After hearing feedback from Canadian founders in our network, we’ve decided to add Canada back to our list of accepted countries of incorporation.
Going forward, YC will once again invest in US, Canada, Cayman, and Singapore corporations.

They are all a showcase... a fucking demo. ChatGPT, Grok, Claude. The world has not yet witnessed true excellence on the layer of the assistant.

The AI wars will not be won at the model level. Just like Apple didn't win at CPUs.

Kinda feeling let down by how everything turned out compared to what was promised. I was hoping for a next Apple type of company and turns out it's not. Oh well.

You can't beat a giant just by being better at their chosen optimization targets. You beat them by being world-class, at your own targets, and hoping they actually matter as much as you think they do.
