NetworkX from NVIDIA is one THE most popular Python graph analytics library with ~15K Github starts and 80M downloads monthly.

This library is for working with networks and graphs. It helps analyze connections between things - like social networks, computer networks, or any system where objects are connected to each other.

And now NetworkX just got massively accelerated after its backend integration with NVIDIA's cuGraph.

✨ Up to 500x speedups on large graph workloads in NetworkX with zero code changes.

And it is Zero Code Change Acceleration.

📌 cuGraph is NVIDIA's GPU-accelerated graph analytics library within the RAPIDS ecosystem. The library provides fast graph algorithms on GPUs, supporting property graphs, remote operations, and graph neural networks (GNNs). Works with GPU DataFrames (cuDF) and integrates smoothly with NetworkX-like API.

--------

📌 The traditional bottleneck of NetworkX's pure Python implementation becomes apparent when processing graphs larger than 100K nodes and 1M edges.

📌 And so now cuGraph solves this by offloading supported algorithms to the GPU. PageRank, Louvain community detection, betweenness centrality, and about 60 other algorithms get instant acceleration.

📌 This acceleration enables previously impractical use cases. Fraud detection systems can now process massive transaction networks in real-time. Recommendation engines handle millions of user-item interactions efficiently. Social network analysis scales to entire platforms worth of data on a single machine.

Preprint on "BWT construction and search at the terabase scale". We can compress 100 human genomes to 11GB in 21 hours, find SMEMs with it, do affine-gap alignment and retrieve similar local haplotypes. 7.3Tb commonly sequenced bacterial genomes ⇒ 30GB https://t.co/DiRwZNHVVa

Introducing Critique Fine-Tuning (CFT): a more effective SFT method for enhancing LLMs' reasoning abilities.
📄 Paper: https://t.co/oK4vCIMP7z
CFT is simple: instead of training models to directly answer questions, we train them to critique noisy answers.

What's fascinating is that while most approaches focus on using generative critique or reward models to provide feedback for policy models, these critique models can themselves serve as policy models： directly answering questions with stronger reasoning.

Interestingly, we also found that CFT saturates quickly: overtraining on critiques can even degrade problem-solving performance.

DeepSeek [1] uses elements of the 2015 reinforcement learning prompt engineer [2] and its 2018 refinement [3] which collapses the RL machine and world model of [2] into a single net through the neural net distillation procedure of 1991 [4]: a distilled chain of thought system.

o3-mini is out!

smart, fast model.

it can search the web, and it shows its thinking.

available to free-tier users! click the "reason" button.

with ChatGPT plus, you can select "o3-mini-high", which thinks harder and gives better answers.

* Fall under Earth's gravity (9.8 m/s²)
* Have collision detection based on their actual letter shapes
* Interact with other letters, ground, and screen boundaries
* Have density properties similar to water
* Dynamically adapt to screen size changes
* Display on a dark background

Gemini 2.0 doesn’t get nearly enough credit. I just dumped all my workers-qb source code into it, hit it with a simple, humble prompt, and boom =&gt; it one-shotted the docs.
Not just good docs, way better than what I had before, packed with examples.
Kinda insane.
