About
About nebx
nebx explores advanced artificial intelligence, autonomous agents, AI research and the infrastructure they run on, and ships free tools for developers.
What nebx works on
Advanced AI
Reasoning, planning and long-horizon problem solving in modern models.
Reasoning and planning · Multimodal models · Long-context memory
Superintelligence
What systems more capable than people could mean, and the safeguards they need.
Alignment · Scalable oversight · Risk and governance
Autonomous agents
Agents that use tools, keep memory and coordinate with each other to finish real tasks.
Tool use · Multi-agent coordination · Agent evaluation
AI research
Reading, reproducing and explaining research in plain language.
Paper notes · Reproductions · Benchmarks and evals
AI infrastructure
The systems underneath: serving, retrieval, compute scheduling and observability.
Inference serving · Vector search and RAG · Cost and observability
How we work
Safety first
Capability work and safety work move together. Every agent experiment ships with limits and a way to stop it.
Open by default
Notes, code and results are published, including the experiments that didn't work.
Measure, don't hype
Claims come with evaluations, not demos. If we can't measure it, we say so.
People stay in control
Autonomous systems act on behalf of people, with oversight built in from the start.
