Cerebral Valley – Week of April 6th 🗓
JetBrains and OpenAI bring Codex to the IDE at a two-day SF hackathon, plus AI events, news and open roles...
You Might’ve Missed
TurboQuant on Blackwell B200 — @anirudhbv_ce implemented Google Research's TurboQuant as a CUDA-native compression engine on NVIDIA's Blackwell B200, achieving 5x KV cache compression on Qwen 2.5-1.5B with near-lossless attention scores. Built 5 custom cuTile CUDA kernels including fused attention with QJL corrections, online softmax, and pipelined TMA loads.
LLM trained on pre-1900 text rediscovers physics — @hla_michael trained an LLM from scratch exclusively on pre-1900 text to see if it could arrive at quantum mechanics and relativity. While too small for deep reasoning, the model showed glimpses of intuition — declaring that "light is made up of definite quantities of energy" and suggesting gravity and acceleration are locally equivalent. Dataset and models are open-sourced.
mlx-vlm v0.4.3 — @Prince_Canuma ships a major update to mlx-vlm with day-0 support for Gemma 4 (vision, audio, MoE) from DeepMind, Falcon-OCR and Falcon Perception from TII, and Granite Vision 4.0 from IBM Research. Also adds SAM 3.1 with Object Multiplex from Meta, RF-DETR from Roboflow, TurboQuant KV cache compression, and CUDA support for vision models.
Introducing Republic — @m_adams launches Republic, a tool for monitoring what's happening in your city. Tracks political news, crime, permits, events, and community groups across the city and at the neighborhood level.
EgoNav: humanoid navigation from human walking data — @KenWangWeizhuo presents EgoNav — 5 hours of a person walking around campus with cameras is all the training data needed. The result: a humanoid robot that navigates unseen buildings, crowds, and glass walls with zero robot data and zero finetuning. Behaviors like waiting for doors, steering around invisible glass walls, and yielding to pedestrians all emerged from the human walking prior.
OpenAI hiring SLAM engineers — @danfei_xu highlights that OpenAI is now hiring for SLAM (simultaneous localization and mapping) engineers — a signal that the company is pushing deeper into robotics and spatial intelligence.
AI-powered hedge fund — @nvonbodungen shares that he's been busy building Pentamerus, a hedge fund built entirely on AI.

Featured in March:
🗓️ Wednesday, April 15th
📍 Virtual (Free)
Seven and a half hours of live technical sessions and hands-on learning dedicated to the future of AI with knowledge graphs. Three tracks: Knowledge Graphs & GraphRAG, Graph Memory & Agents, and Graph + AI in Production. AI engineers will explore the latest techniques for context engineering, agentic systems, evals, MCP, and working with the latest models.

📍 San Francisco, California
Unlock the power of Codex inside your IDE
We know IDEs must evolve with the tools. Let's hack together to build tooling to harness the next generation of development.
JetBrains is hosting a two-day hackathon in San Francisco, supported by OpenAI, to put Codex to work inside the IDE where your codebase lives. This isn’t a “toy project” weekend — this is about building real tools, real systems, and real workflows with AI embedded where you actually work.
Build developer tools, testing frameworks, refactoring pipelines, coding agents, and ship real value. Come with a team or find one on-site (a lot of people do)!

🗓️ Monday April 20th
📍 Shack15, San Francisco, CA
Beltic x Shack15 host a private dinner on identity and trust in the agentic economy. Founders, investors, and enterprise leaders across AI, fintech, and infrastructure discuss how trust evolves as systems move from human-driven to agent-driven. Fireside speakers include Kevin Leffew (x402, Coinbase — an open protocol for autonomous agent payments over HTTP), Jørn Lyseggen (Founder at Shack15 and BKEY, 20 years in identity), and Dazza Greenwood (CodeX, Stanford Law & MIT — AI governance and accountability). Space limited, approval-based.
This Week in SF:
🗓️ Wednesday, April 8th 📍 Embarcadero, San Francisco, CA
Leaders from frontier AI research labs come together to explore "High-GDP Agents" — AI systems capable of reliably performing work tied to real economic output. Panel discussion on where agents produce significant value today, how to scale from one agent to a billion, and whether current benchmarks can predict real-world agentic GDP impact. Speakers include Andi Peng (Co-founder, humans&), Patrick Tammer (AI Strategy & Ops Lead, Google), Linda Lu (Responsible AI Researcher, Berkeley RDI), and Paco Guzmán (Head of Research, Handshake AI).
🗓️ Wednesday, April 8th 📍 The House by Edge & Node, San Francisco, CA
The closing celebration of Sentient's Arena Cohort 0 — three weeks of competition where top AI researchers and engineers developed frontier reasoning systems for Grounded Reasoning over Large Corpora. The top 10 projects demo their work on stage, followed by a workshop with Himanshu Tyagi (Co-Founder, Sentient) and a happy hour. Free and open to all AI founders and developers.
🗓️ Thursday, April 9th
📍 Pacific Heights, San Francisco, CA
The most ambitious founders showcase a month's worth of work at Lightyear's Demo Day. Incubated by HF0, the residency brings founders building at the boundaries of AI, robotics, neuroscience, and finance. 40% of teams broke $2M annualized revenue, one hit $10M ARR. One founder built a SOTA foundation model beating NVIDIA benchmarks. Doors at 4pm, demos at 4:30, founder meet & greet at 5.

Deep-dive automation demos and community networking with 60 builders. Three speakers: Richard Emanuel (Streamline Connector) on scaling a Shopify automation agency with n8n, Pranav Kowadkar on multi-agent orchestration for an AI job search pipeline, and Arnaud Bieri (Courier Health) on running n8n in a HIPAA-compliant healthcare SaaS environment. Food, drinks, n8n swag. Space limited to 60.
