xAI announces Grok 3. Here is everything you need to know

Elon mentioned that Grok 3 is an order of magnitude more capable than Grok 2.

Total GPUs: 200K

The capacity was doubled in 92 days!

All of this compute was used to improve Grok -- which has lead to Grok 3.

Grok 3 involved 10x more training than Grok 2!

Grok finished pretraining in early January!

The model is still training.

Here are the benchmark numbers:

Grok 3 significantly outperforms other models in its category such as Gemini 2 Pro and GPT-4o. Even Grok-3 mini shows to be competitive.

It reached an Elo score of 1400 which no other model has achieved.

The model score keeps improving.

Grok 3 also has reasoning capabilities too!

The Grok team has been testing these capabilities which they have unlocked using RL.

The model is good, especially in coding.

Grok 3 coding example:

Elon confirmed that the thinking steps have been obscured to avoid getting copied.

Grok 3 also excels at creative coding like generating creative and novel games.

Elon emphasized Grok 3's creative emergent capabilities.

You can also use the Big Brain mode to use more compute and reasoning with Grok 3.

Grok 3 Reasoning performance:

The results correspond to the beta version of Grok-3 Reasoning.

It outperforms o1 and DeepSeek-R1 when given more test-time compute (allowing it to think longer).

The Grok 3 mini reasoning model is also very capable.

Grok 3 cannot only unlock test-time compute, it also enables capable agents.

These capabilities have led to a new product called DeepSearch.

"Next generation of search agents to understand the universe".

More on DeepSearch:

- the model can think deeply about user intent
- what facts to consider
- how many websites to browse
- it can cross-validate different sources.

DeepSearch also exposes the steps that it takes to conduct the search itself.

Improvements will happen rapidly and almost daily according to the team.

There is also a Grok-powered voice app coming too -- about a week away!

Open-source approach:

The last version will be open-sourced when the most recent version is fully out.

After Grok 3 stable version is out, it is highly likely Grok 2 will be open-sourced. (within a few months).

SuperGrok dedicated app is also available with a polished experience.

Breakthrough in Robot Design: Universal Controllers Transform How We Build Robots?

Northwestern University researchers have made a significant breakthrough in robotics design, introducing a method that could revolutionize how we create and evolve robots.

Their paper "Accelerated co-design of robots through morphological pretraining" presents a novel approach that solves a decades-old challenge in robotics.

Code is coming soon.

And here are more robots

Key Innovations:

1. Universal Controller

- Developed a single controller that can work with multiple robot body types
- Pre-trained on millions of different robot morphologies
- Uses gradient-based optimization through differentiable simulation
- Can immediately adapt to new robot designs without extensive retraining

2. Zero-Shot Evolution

- Allows rapid testing of new robot body designs
- Enables immediate evaluation of design changes
- Supports successful recombination of robot parts
- Dramatically speeds up the design process

3. Diversity Maintenance

- Identified and solved "diversity collapse" - a previously unknown problem in robot co-design
- Developed methods to maintain morphological diversity while improving performance
- Enabled successful crossover between different robot designs

Technical Details:
- Controllers are trained on over 10 million distinct robot morphologies
- Uses differentiable simulation for gradient-based optimization
- Supports complex 3D environments with varying terrains
- Enables robots to perform adaptive behaviors like phototaxis (movement toward light)

Future Implications:

- Could dramatically accelerate robot design and development
- Opens new possibilities for self-reconfigurable robots
- Provides a framework for more complex multi-material robots
- May help bridge the simulation-to-reality gap in robotics

HuggingFace released the "Ultra-Scale Playbook"

A free, open-source, book to learn everything about 5D parallelism, ZeRO, fast CUDA kernels, how and why overlap compute & communication – all scaling bottlenecks and tools introduced with motivation, theory, interactive plots from our 4000+ scaling experiments and even NotebookLM podcasters to tag along with you.

- How was DeepSeek trained for $5M only?
- Why did Mistral trained an MoE?
- Why is PyTorch native Data Parallelism implementation so complex under the hood?
- What are all the parallelism techniques and why were they invented?
- Should I use ZeRO-3 or Pipeline Parallelism when scaling and what's the story behind both techniques?
- What is this Context Parallelism that Meta used to train Llama 3? Is it different from Sequence Parallelism?
- What is FP8? how does it compares to BF16?

The largest factor for democratizing AI will always be teaching everyone how to build AI and in particular how to create, train and fine-tune high performance models. In other word making accessible to everybody the techniques that power all recent large language models and efficient training is possibly one of the most essential of them.

Wow, DeepSeek announced Day 0: Warming up for OpenSourceWeek

Starting next week, they'll be open-sourcing 5 repos, sharing sincere progress with full transparency.

These humble building blocks in their online service have been documented, deployed and battle-tested in production.

Daily unlocks are coming soon. No ivory towers - just pure garage-energy and community-driven innovation.

GPT-4.5 is out! Knowledge Still Stuck in October 2023, it’s not going to blow your mind, but it might befriend you.

It's more like a personality, communication, and creativity upgrade than a huge intelligence leap. It's like OpenAI is pivoting its base model from "bland assistant" to "AI bestie."

What it does do well:

- OpenAI says it scores 64% on SimpleQA (double GPT-4's score)
- Much better writing with cleaner, better structured, more human-like prose
- Genuinely warmer and more emotionally intelligent (gave me some good advice!)
- Less robotic, more opinionated responses

4.5 is more extroverted, agreeable, and less neurotic than 4o.

It's sometimes worse at following instructions and because it's less sycophantic and more creative.

The model received approximately 10x more computational resources during pre-training compared to GPT-4. Training occurred simultaneously across multiple data centers.

Pricing $75 per million input tokens and $150 per million output tokens – 15-30x more expensive than GPT-4o! This pricing reflects the model's scale and resource requirements.

Performance and Context Generation is noticeably slower than its predecessors, context length remains at 128K tokens. Knowledge cutoff stays at October 2023, which is disappointing for many users.

Functionality Supports Canvas, search, and file uploads. Currently lacks multimodal features like voice mode or video.

Availability:
Already available to Pro users and developers of all API tiers
Coming to Plus subscribers ($20) next week
OpenAI plans to add "tens of thousands of GPUs" next week to expand access

Independent Benchmark Results:
Aider Polyglot Coding Benchmark: Recent tests show that GPT-4.5 Preview significantly outperforms its predecessor but lags behind specialized models:
Claude 3.7 Sonnet with thinking mode (32k tokens) — 65%
Claude 3.7 Sonnet without thinking mode — 60%
DeepSeek V3 — 48%
GPT-4.5 Preview — 45%
ChatGPT-4o — 27%
GPT-4o — 23%

Today Anthropic submitted their recommendations to the OSTP for the U.S. AI Action Plan

Anthropic predicts powerful AI systems will appear by late 2026 or early 2027, with intellectual abilities matching Nobel Prize winners, able to autonomously handle digital tasks (text, audio, video, internet browsing), reason independently over hours or weeks, and control physical equipment digitally

They recommend stronger national security actions, including government testing of AI models for security risks, stricter export controls on key chips like the H20, and secure communication channels between AI labs and intelligence agencies

They suggest the government build 50 gigawatts of additional power capacity dedicated to AI by 2027, speed up AI adoption across federal agencies, and improve economic data collection to prepare for AI’s impact on jobs and society
