I'm launching an urgent fundraiser to support engineering equipment for our frontline efforts, and I need your help. Please donate, like, share, and comment—every bit of support is crucial. You can find the donation link at the end of this message. The situation on the front lines is incredibly challenging. Errors by political and military leaders, combined with slow support from the West, have led to significant losses in both territory and lives in the Pokrovsk axis. While we can't always change the decisions made by our leaders, we can make a real difference by providing our soldiers with essential engineering equipment. For instance, I personally have reservations about the operation in Kursk for my own reasons. However, I am fully committed to doing everything I can to save Ukrainian lives during this operation. That’s why one of Liberty Ukraine Foundation 🇺🇸🇺🇦’s excavators is already at work at the new positions on that axis. Our efforts to save soldiers' lives should remain focused regardless of individual opinions on tactical or strategic decisions made by our Ukrainian leadership. Thanks to the fundraising efforts of Liberty Ukraine Foundation 🇺🇸🇺🇦, we have already transferred or are in the process of transferring over 8 excavators. The feedback has been overwhelmingly positive, with engineering, infantry, and artillery units reporting that this equipment is saving many lives. On both the Kursk and Pokrovsk axes, the front lines are constantly shifting, which makes the need for excavating equipment even more critical. This equipment allows our forces to adapt quickly and operate more effectively. Our goal is to raise 🎯 $110,000. I know this is a substantial amount, but we've successfully raised even more in the past, and this equipment is making a significant impact right now. donation link 🔗 Thank you for your support.

We’re excited to introduce ShinkaEvolve: An open-source framework that evolves programs for scientific discovery with unprecedented sample-efficiency. Blog: Code: Like AlphaEvolve and its variants, our framework leverages LLMs to find state-of-the-art solutions to complex problems, but using orders of magnitude fewer resources! Many evolutionary AI systems are powerful but act like brute-force engines, burning thousands of samples to find good solutions. This makes discovery slow and expensive. We took inspiration from the efficiency of nature. ‘Shinka’ (進化) is Japanese for evolution, and we designed our system to be just as resourceful. On the classic circle packing optimization problem, ShinkaEvolve discovered a new state-of-the-art solution using only 150 samples. This is a big leap in efficiency compared to previous methods that required thousands of evaluations. We applied ShinkaEvolve to a diverse set of hard problems with real-world applications: 1/ AIME Math Reasoning: It evolved sophisticated agentic scaffolds that significantly outperform strong baselines, discovering an entire Pareto frontier of solutions trading performance for efficiency. 2/ Competitive Programming: On ALE-Bench (a benchmark for NP-Hard optimization problems), ShinkaEvolve took the best existing agent's solutions and improved them, turning a 5th place solution on one task into a 2nd place leaderboard rank in a competitive programming competition. 3/ LLM Training: We even turned ShinkaEvolve inward to improve LLMs themselves. It tackled the open challenge of designing load balancing losses for Mixture-of-Experts (MoE) models. It discovered a novel loss function that leads to better expert specialization and consistently improves model performance and perplexity. ShinkaEvolve achieves its remarkable sample-efficiency through three key innovations that work together: (1) an adaptive parent sampling strategy to balance exploration and exploitation, (2) novelty-based rejection filtering to avoid redundant work, and (3) a bandit-based LLM ensemble that dynamically picks the best model for the job. By making ShinkaEvolve open-source and highly sample-efficient, our goal is to democratize access to advanced, open-ended discovery tools. Our vision for ShinkaEvolve is to be an easy-to-use companion tool to help scientists and engineers with their daily work. We believe that building more efficient, nature-inspired systems is key to unlocking the future of AI-driven scientific research. We are excited to see what the community builds with it!

Say hello to Boojum 👋: zkSync Era’s new high-performance proof system for radical decentralization. Boojum is an upgrade that will transition zkSync Era to a STARK-powered proof system, providing world-class performance on consumer-grade hardware. 💡 Learn more: TL;DR 👇 Boojum is the name of our Rust-based cryptographic library, which we use to implement the upgraded version of the ZK circuits for zkSync Era and the ZK Stack. The name Boojum was inspired by Lewis Carroll's poem "The Hunting of the Snark," where the Boojum represents the most fearsome kind of Snark. We intentionally designed zkSync Era in a way that cryptographic upgrades can be made without a regenesis, meaning that the Boojum upgrade won’t cause any user disruptions. Why Boojum❓ From day one, zkSync’s mission is to advance personal freedom for all — making digital self-ownership universally accessible by building a blockchain network that is trustless, secure, permissionless, affordable, easy to use, resilient and limitlessly scalable. Boojum plays an important role in advancing this mission by delivering: 1. World-class performance zkSync Era’s current SNARK-based proof system is effective today, but it won’t scale to the volume that we envision for hyperchains. zkSync Era’s sequencer can already process over 100 TPS; Boojum orders of magnitude improvements to performance complements this well. 2. Reduced hardware requirements for decentralization Our long-term goal is to enable user-powered, decentralized proof generation. Boojum represents a breakthrough in this direction — with the prover running on consumer-grade GPUs requiring only 16 GB GPU RAM. Boojum’s Journey to Mainnet 🚴🏽‍♀️ Boojum is now live on Mainnet, generating and verifying ‘shadow proofs’ today with real production data so that we can carefully test the system ahead of fully migrating. Today, we’re also open-sourcing the repo; if you’d like to take a look, you can find it here 👇 This is the first of a series of posts on Boojum. We will provide updates on our progress, including more details on implementation, security, and performance. Watch here for more, anon ∎

HapdZi Birthday, Sam! As many of you are aware, as part of this year's "Sam's Birthday Fundraiser" we have been raising funds for the dZi Foundation. The dZi foundation works along side communities in Nepal providing support, infrastructure, knowledge, education, and upskilling, whilst working towards sustainability and self-sufficiency. They are doing truly amazing work within these communities and I am so very glad that they are this year's recipient. Now for the exciting part! Drum roll, please... I am very proud to announce that we were able to raise $32, 290USD! Yes, you read that correctly! $32,290USD! Thank you to everyone who has donated, those who were cheerleaders, and those who were donators and cheerleaders. I am so incredibly proud of our community and I hope that you are too! You guys are fabulous! I would also like to extend my sincere thanks to Jake Norton for sharing his love of Nepal and its people with us. By sharing his memories, and parts of his recent trip with Sam, we were able to have a personal connection with both the people and the places that our donations will benefit. For that I will always be grateful to Jake. I would also like to thank Jake for his very, very generous donation match during the last week of the fundraiser. It was great to see Jake ensure that "Sam" finally made it to the top of "Everest." (Where there's a will, or in this case, a Jake, there's a way!) As always, it is lovely to hear from the organizations that we raise money for each year and this year is no different. Please take a moment to listen to this lovely message of thanks from Wende Valentine, Executive Director at dZi. It is reminder of just how important our philanthropy is, and, that wherever we are in this wonderful world of ours we can always make a difference in the lives of others. "It takes a village. Ours just happens to be sparkly." #SamHeughan
