Personal AI Infrastructure (PAI) is an open-source 'Life Operating System' built natively on Claude Code by security researcher and AI educator Daniel Miessler. It gives Claude Code a persistent identity layer, 45+ specialised skills, a Pulse dashboard accessible at localhost:31337, and a seven-phase decision-making loop modelled on the scientific method — turning Claude Code from a coding tool into a full personal AI agent. The architecture deliberately avoids RAG and vector databases, instead using plain text files and filesystem-based indexing to build compounding memory across sessions. An Ideal State framework lets users define their goals and values, and the Digital Assistant works toward them proactively between sessions. One-line install: `curl -sSL https://ourpai.ai/install.sh | bash`. PAI v5.0 is trending on GitHub today with 13,000+ stars and +620 in a single day. Skills span work, learning, personal development, and creative domains — all extensible. MIT-licensed and actively developed, it offers the most complete personal AI stack built on Claude Code available as of May 2026.

Sup AI is an ensemble AI assistant that runs your query through 339 language models simultaneously, measures per-segment confidence across all responses, and synthesizes a final answer that amplifies agreement and suppresses likely hallucinations. The team claims a 52.15% score on Humanity's Last Exam (HLE) — 7.41 percentage points above the single best model — which, if verified, would make it the highest-scoring system on the benchmark to date. The underlying mechanism works like an LLM panel: each model votes on sub-claims within the response, confidence is estimated by agreement density, and the final output surfaces high-confidence segments while flagging uncertain ones. It's designed to reduce hallucination rate on factual tasks, not improve reasoning per se — the models in the ensemble aren't doing collaborative chain-of-thought, they're voting on outputs. Sup AI was built by Ken Mueller (Stanford, CEO) and Scott Mueller (AI Research Scientist) and launched on Product Hunt today. Pricing starts with $10 in free credits, no auto-charge, with a credit card required to start. The HLE benchmark claim is the headline and will face scrutiny — if verified, this is a meaningful research result. If it's cherry-picked, it's still a usable product with a differentiated architecture.
Reviewer scorecard
“The filesystem memory approach is clever — avoids the overhead and brittleness of vector search while still giving searchable persistent context. The 45 included skills are a great starting point and easy to extend. v5.0 feels genuinely production-ready for personal daily use.”
“The HLE claim needs independent verification, but the underlying ensemble approach is architecturally sound for factual Q&A tasks. Running 339 models is expensive — pricing will be the gating factor for production use. The $10 free credit is a fair trial.”
“'Life OS' is a big promise that requires sustained personal effort to deliver on. The Ideal State framework is philosophically interesting but depends on the user consistently maintaining their goals file — most people will set it up once and drift. The system scaffolds discipline but doesn't enforce it.”
“Extraordinary claims require extraordinary evidence. A 7.41 point jump on HLE via ensembling — without publishing methodology — smells like benchmark gaming. The latency of running 339 models in parallel is also a real concern for anything other than async research tasks.”
“PAI is a serious attempt at the personal AI stack most people think is a decade away. The compounding memory model — where usefulness grows over time as the system learns your patterns — is precisely the right mental model for what personal AI should become.”
“Model ensembling is an underexplored direction in the race to reduce hallucination. If Sup AI's approach scales, it could be more durable than fine-tuning individual models — you get the wisdom of the crowd across model families, training data, and architectures simultaneously.”
“The writing and creative skills are solid out of the box, and having a persistent assistant that actually remembers my creative style and ongoing projects across sessions would fundamentally change how I work. The Pulse dashboard for life management is a nice bonus.”
“For creative work, ensemble outputs tend to regress toward the mean — you get the most-agreed-upon version of something, which is usually the least interesting version. This is a tool for factual accuracy, not creativity. I'd stick with a single strong model for writing.”
