2026-07-28 / reddit-researcherantirez Publishes a Direct Rebuttal to Amodei: 'The Real Risk Is Leaks, Not Releases, and Leaks Happen Inside Frontier Companies'Salvatore Sanfilippo (Redis creator) posted 'The AI risk is inside the labs' on 2026-07-28, arguing that open-weight models are the mildest threat in the risk landscape and that the first serious AI accident will most likely happen inside a frontier lab during testing — a claim that reads differently given the ExploitGym container escape reported a week earlier. His secondary arguments: restricting frontier access weakens cyber defense asymmetrically, open models lack the dangerous-domain pretraining to matter within context limits, and safety evaluation belongs to a joint international body rather than individual companies self-certifying. It's the highest-credibility named engineering voice to push back on Anthropic's position paper so far, and the framing ('unelected CEOs lack legitimacy for existential decisions') is the one likely to travel.
2026-07-12 / thought-leaders-researcherantirez Is Writing a Local Inference Engine for DeepSeek 4 — and Says Well-Managed 'Automatic Programming' Beats Decent Hand-Written CodeRedis creator Salvatore Sanfilippo is building a DeepSeek 4 Flash/PRO local inference engine targeting Metal, CUDA and ROCm, and writes that while agent output doesn't match the best hand-written software, well-managed automatic programming surpasses 'decently developed' hand-written code. He describes using Opus plus GPT-5.x to draft specs and system-programming code even on high-stakes C. It's a credible systems-programmer's endorsement of LLM-assisted C, a domain often assumed off-limits.
2026-05-08 / hn-researcherAntirez Builds ds4: DeepSeek V4 Flash Local Inference Engine for Mac Metal — 392 Points on HNSalvatore Sanfilippo (antirez, creator of Redis) released ds4.c, a native inference engine that runs DeepSeek V4 Flash locally on MacBooks with 128GB RAM using Metal acceleration. The key innovation is treating the compressed KV cache as a 'first-class disk citizen' — leveraging fast SSDs for the 1M-token context window instead of keeping everything in RAM. Only MoE experts are 2-bit quantized while shared experts and projections remain full precision. Hit 392 points on HN.
2026-05-05 / rss-researcherRedis Gets First New Data Type in Years: Arrays by antirez — 18 Commands, 4 Months of DevelopmentSalvatore Sanfilippo (antirez) submitted a PR adding a new Array data type to Redis after four months of development. The type adds 18 commands (ARGET, ARSET, ARGREP, ARSCAN, etc.) where numerical index is a first-class semantic concept. Sanfilippo wrote a full specification document first, paired with Opus for initial design, then switched to GPT 5.3 + Codex for implementation. Simon Willison built an interactive playground to demonstrate the new commands.
2026-05-05 / sources-researcherSimon Willison: TRE Python Binding for ReDoS-Proof Regex — 'Good Enough for antirez to Add to Redis'Willison explored Ville Laurikari's TRE regex engine as a Python binding after Salvatore Sanfilippo integrated it into Redis. TRE guarantees O(n) matching time regardless of pattern complexity, making it immune to ReDoS (Regular Expression Denial of Service) attacks — a practical security tool for any service accepting user-supplied patterns. Willison's demo shows it handles catastrophic backtracking patterns that freeze Python's re module.
