Hey, I'm Steve Wu πŸ‘‹

AI Engineer & LLM Researcher

Building AI-native tools that actually ship. Obsessed with making large language models more useful, more controllable, and more open.


πŸš€ What I'm Working On

  • πŸ”¬ Abliterix β€” Fully automated LLM abliteration framework. LoRA + Optuna TPE optimization, 135+ model configs, 9 peer-reviewed techniques (NeurIPS/ACL/ICLR). 0–1.5% refusal rate with 0.01 KL divergence.
  • πŸ—„οΈ OpenDB β€” AI-native database & long-term memory for AI agents. 93.6% on LongMemEval (#3 on leaderboard), zero embeddings, zero vector DBs β€” just SQLite FTS5. 12 MCP tools, works with every major agent framework.
  • 🦬 OpenYak β€” Open-source local-first AI desktop app supporting 100+ models
  • 🧠 LLM alignment research β€” abliteration, representation engineering & steering vectors
  • πŸ” Vector search engines & RAG pipelines at scale
  • πŸ€– Multi-agent orchestration β€” built from scratch, no heavy frameworks
  • πŸ“ AI-native writing & knowledge systems
  • πŸ”¬ Publishing fine-tuned & abliterated models on HuggingFace
