Agent Systems
Tool use, orchestration, memory, handoffs, evaluation, and the part where agents meet the real world and get weird.
Hive Fidelity AI
Small agent engineering lab
Hive Fidelity builds sharp tools, sharper evals, and notes worth bookmarking.
We work on interpretability, coding-model architecture, sparse attention, agent systems, and open-source benchmarking. Sometimes that means research. Sometimes it means shipping something that behaves under load. Sometimes it means both, while sleep loses.
Field Logo2026
Agent engineering with tangible production scars
Interpretability and coding-model architecture research
Sparse attention, systems tuning, and open infrastructure
Benchmarks, evals, and notes useful enough to steal
What We Actually Do
Research, systems, and enough receipts to be useful to strangers.
Model Architecture
Coding models, sparse attention, routing strategies, and the performance cliff where promising ideas become engineering work.
Interpretability
Mechanistic curiosity, measurement, and practical analysis that can survive contact with actual model behavior.
Benchmarks & Evals
Repeatable tests, transparent tradeoffs, and receipts instead of vibes whenever we claim something is better.
Operating Mode
Open by default, practical by habit, allergic to benchmark theater.
Research, prototypes, and public notes
Selective collaboration when the problem is spicy enough
Open-source friendly and suspicious of hand-wavy benchmarks
Demos
Live surfaces for the current round of Blackwell nonsense.
Embodied GLM
Vector2GLM Timeline
A robot operations timeline for native Vector reflexes, bridged sensor state, GLM context pressure, tool calls, safety gates, and speech output.
Blackwell Shenanigans
ZAYA Live Eval
A live scoreboard for ZAYA1-8B on the 8x RTX PRO 6000 box: endpoint health, rollout lanes, latency, solved tasks per dollar, and Langfuse traces once the harness starts streaming.

Build Week Field Note 008: Sol Asked His Body For A New Verb
Second Nature grew from one handsome man trapped beside a sofa into a live WebXR agent who can notice a missing movement, ask Codex and Meta Motivo to build it, and gain the new action without leaving the conversation. The tea is not delivered yet. The body finally has a learning loop.

Build Week Field Note 007: Forty-Eight Hours Out — Three Apps And One Raccoon With A Deadline
Three separate products survived the GPT-5.6 beating-heart test. None survived without a Tuesday punch list, and the raccoon has found a clipboard again.
