PixArt-Σ

Weak-to-strong training of diffusion transformer for 4K text-to-image generation.

In this paper, we introduce PixArt-Sigma, a Diffusion Transformer model~(DiT) capable of directly generating images at 4K resolution.

Zuck’s New Plan: LLaMA 3 and the Future of Open-Source AGI

Meta’s latest brainchild, Llama 3, is rewriting the rules of digital communication. This powerhouse AI model doesn’t just compete—it surpasses OpenAI’s GPT-4 and Google’s Gemini. Brace yourself for enhanced responsiveness, multimodal magic, and a dash of ethical finesse.

Under Zuckerberg’s visionary helm, Llama 3 dances with context, reads between the lines and delivers nuanced interactions across platforms. It’s not just about AI; it’s about redefining how we connect. 🚀🤖

A complete reconstruction of the early visual system of an adult insect

Link to paper: Megaphragma is a tiny parasitoid wasp that shows complex behaviors despite its miniscule size.


Chua et al. map the compound eye and the lamina of micro-wasp Megaphragma viggianii in the same specimen with a few-nanometer resolution. The stereotyped cartridge connectome is similar to but simpler than that in larger insects. Dorsal rim specialization in photoreceptor morphology is reflected in the differences in downstream cartridge connectomes.

Exclusive: Techstars’ $80 million partnership with J.P. Morgan is on the rocks, employees say

Techstars has currently invested about two-thirds of the fund, Gavet recently told TechCrunch, adding that the bank is “an amazing partner” and “very active in our program.”

However, J.P. Morgan has yet to tell Techstars whether it will renew the partnership for an Advancing Cities 2 Fund once the initial contract expires in December, sources say. That decision was supposed to be handed down last summer so that Techstars could start fundraising and begin deploying capital in 2025.

This means the fate of the Advancing Cities programs — and some of the around 20 people who work at Techstars in this program — is up in the air.
