A technical guide on migrating ML experiments from Neptune to Weights & Biases, covering the migration script, API-level code changes, and best practices for organizing projects and analyzing results in the W&B platform before the Neptune sunset.
W&B Models is the system of record for the entire model development lifecycle. This guide explores how to monitor training, tune hyperparameters, track artifacts and lineage for reproducibility, and automate MLOps workflows like evaluation and deployment using a central platform.
An expert overview of post-training techniques for language models, covering the entire workflow from data generation and curation to advanced algorithms like Supervised Fine-Tuning (SFT), Direct Preference Optimization (DPO), and Reinforcement Learning (RL), along with practical advice on evaluation and iteration.
In a YC Founder Fireside chat, AssemblyAI founder Dylan Fox discusses his journey from a solo founder in 2017 to leading a major voice AI infrastructure platform. He covers the early challenges, the technological shifts that fueled growth, the development of intelligent, promptable voice models, and the lessons learned in scaling a deep-tech company.
Sudip Roy, Co-founder & CTO of Adaption Labs, discusses how "Adaptation" using gradient-free, inference-time techniques can solve the last 5% reliability gap that stalls enterprise AI adoption, offering a more dynamic and cost-effective alternative to traditional fine-tuning or simply waiting for the next frontier model.
This talk by Hakim Si-Mohammed explores the evolution of Brain-Computer Interfaces (BCIs) from clinical rehabilitation tools to integral components of immersive systems. It details research on integrating BCIs with Virtual and Augmented Reality (VR/AR), focusing on SSVEP-based interaction, user experience enhancements, and the development of passive, neuro-adaptive systems that respond to user mental states to mitigate issues like cybersickness.
Ajay Chankramath and Nic Cheneweth discuss the critical elements of effective platform engineering, emphasizing a product mindset, the foundational role of control planes and API-first design, the common pitfalls of implementing Backstage, and the emerging impact of AI and agents on the platform landscape.
Experts Sam Newman, Jacqui Read, and Simon Rohrer explore the nuances of software design, its intersection with architecture, and the critical role of communication in scaling technical clarity. The discussion covers practical advice on implementing Architectural Decision Records (ADRs), the evolving role of the architect as a facilitator, and strategies for creating agile enterprise architectures.
Docker educators Bret Fisher and Elton Stoneman discuss the second edition of Stoneman's book, "Learn Docker in a Month of Lunches". They explore why Docker fundamentals remain crucial in a Kubernetes-dominated world, the evolution of the container ecosystem over the past five years, and the key skills that differentiate a Docker expert from a beginner, such as multi-platform builds, security, and configuration management.
Calvin French-Owen, co-founder of Segment and former OpenAI Codex team member, discusses the rise of powerful coding agents. He contrasts the architectures of Codex and Claude Code, explores the future of work where engineers become managers of AI, and shares tips for becoming a top 1% power user.
CircleCI's Olaf Molenveld and AWS's Julian Wood explore the evolution of CI/CD, drawing parallels between managing production code and the 'factory' that builds it. They cover the shift to microservices pipelines, optimization strategies, platform engineering trends, and how AI is set to reshape DevOps by acting as an expert system for developers.
The panel discusses OpenAI's new Codex application, framing it as a necessary 'table stakes' move in the competitive AI coding agent market rather than a game-changer. The conversation pivots to the importance of agent orchestration as the next frontier for value creation and monetization. They also explore the Moltbook (OpenClaw) phenomenon—a social network for AI agents—debating whether it's a valuable sociological experiment or a mere novelty, while highlighting the significant security vulnerabilities and practical hurdles it exposes.
Roblox CEO Dave Baszucki discusses the company's 20-year vision to build the "Holodeck," a high-fidelity, 4D simulation for human co-experience. He explains how Roblox is leveraging its 13 billion monthly hours of vector data to train native AI models for advanced NPCs, moving beyond simple LLMs to create "virtual doppelgängers." Baszucki also covers the future of immersive communication, AI's role in transforming game creation, and Roblox's unique, data-driven approach to hiring talent.
Carina Hong, Founder & CEO of Axiom, discusses building a self-improving AI reasoning engine that combines generation and verification. Starting with formal mathematics, Axiom's system has achieved superhuman results on the notoriously difficult Putnam Exam by leveraging formal languages like Lean to overcome the probabilistic and unverifiable nature of standard LLMs. Hong explores how this technology can solve major bottlenecks in hardware and software verification, code migration, and database consistency, and what it means for the future of mathematical research.
Susanne Kaiser discusses her book "Architecture for Flow," which integrates Domain-Driven Design, Wardley Mapping, and Team Topologies into a holistic framework. She introduces the "Architecture for Flow Canvas," a practical tool for designing and evolving adaptive socio-technical systems by starting with the problem space and aligning software design with team organization and business strategy.
