Meet Brian
Brion's quantum agent — wired to hardware, not to a script.
Ask Brian
Running on Brion's own hardware. Ask him to run a circuit, compute a molecular ground state, or tell you whether something is feasible — the tools he calls appear under each answer.
What Brian can reach, right now
Probed live every time this page loads — not a configuration file. A resource that is down appears with the reason, because an agent that hides an outage is an agent whose answers you cannot trust.
Brian caps his own circuits at 24 qubits. The hardware goes higher; a conversation should not be able to queue an hour of compute by accident.
Run one of his tools
These are the same tools Brian calls. Each one executes on a real backend and returns measurements — nothing here is a canned response.
Pick a tool above. The feasibility tool is the interesting one. Ask whether we can fold a peptide and the answer is yes, with the qubit count and the paper. Ask about mRNA and the answer is no, by a factor of 22, with the classical method that does solve it. An agent that only says yes is not an expert. It is a salesman.
His tool surface
Five tools, each one a real capability. The schemas are published in the Anthropic tool-use format, so the reasoning layer is configuration rather than a rewrite.
Where Brian is today
Brian's hands are built and connected: he reaches an 8-GPU simulator fleet across two nodes, an in-process simulator, and Origin Wukong — a 180-qubit superconducting quantum processor. A Bell pair submitted through him returns from real hardware in about thirteen seconds, with roughly one shot in two thousand landing outside the entangled state. That residue is device error, and it is the clearest evidence there is that the computation happened on physical qubits rather than in a simulator.
His reasoning layer runs on Brion's own GPUs — an open-weights model served on the same fleet that runs the simulators, with no external API in the path. It reads your question, decides which tool to reach for, and explains what came back. Every quantitative claim he makes about quantum hardware comes from a tool call you can see in the trace under his answer.
What he will not do
Brian carries a feasibility tool with published qubit counts and citations, and he is built to use it before promising anything. Ask him to fold a 300-residue protein and he will tell you it needs about 600 qubits against the 24 he is allowed, cite Robert et al., npj Quantum Information 7, 38 (2021), and point you at AlphaFold. Ask about mRNA secondary structure and he will note it scales as roughly n² in sequence length, so a 30-base sequence already wants 435 qubits — and that ViennaRNA solves it classically in milliseconds.
This is the useful behaviour, not a limitation of it. A scientist can work with a system that knows its own edges. Nobody can work with one that agrees with everything.
