The Engines Powering Helektron
Four purpose-built Ai engines — from fast modular generation to deep multi-board system reasoning — each suited to a different kind of circuit-design work.
Nexus
FlagshipMaximum reasoning, maximum system complexity.
Nexus is Helektron's highest-end Ai engine, built for deep, multi-component reasoning and complete system synthesis — combining engineering knowledge across component catalogs with advanced architectural reasoning.
Rather than asking “what components can make this circuit?”, Nexus reasons more like “how should the complete electronic system be architected to satisfy these requirements?” Its strength is architectural reasoning across an entire system, not a single circuit block.

- Sensors
- Power-management components

Swarm
Advanced ReasoningDeeper PCB engineering reasoning, especially around signal, power, and verification.
Swarm is Helektron's advanced-reasoning engine, focused on power integrity, signal routing, rule verification, high-speed buses, and production-grade PCB design.
Swarm isn't positioned as the fastest circuit generator — its purpose is deeper reasoning about how a PCB should behave electrically, and whether the resulting design satisfies important engineering constraints.
Key Capabilities & Workloads
- High-speed signals
- Signal routing
- Power integrity
- PCB constraints
- Design-rule considerations
- Production-oriented single-board designs

Hive
Balanced Multi-AgentBalanced intelligence with multi-agent component research and compatibility reasoning.
Hive is Helektron's balanced engine, built around multi-agent execution — its primary distinction is running parallelized tasks, particularly around component and datasheet research.
Hive's flow runs user requirement → component research → datasheet information → pin compatibility → circuit generation. Rather than maximizing reasoning depth or minimizing generation time, Hive balances intelligence, complexity, and speed.
Key Capabilities & Workloads
- Investigating several components and how they fit together
- Parallel datasheet search across multiple components at once
- Pin compatibility matching between selected parts
Reasoning
Multi-agent execution
Generation time
~15–30 seconds
Complexity
Medium–High
Best suited for
Designs needing component research and compatibility checking

Cell
Fastest GenerationFastest generation for standard, modular circuit designs.
Cell is Helektron's fastest engine, built for generating modular circuit blocks quickly using focused topology lookup rather than deeper multi-step reasoning.
Cell makes sense when you already know approximately what type of circuit you need and want to generate a relatively standard circuit quickly — modular problems where speed matters more than extensive system-level reasoning.
Key Capabilities & Workloads
- Sensor interfaces
- Power regulators
- Standard peripheral topologies
- Circuits where the general topology is already known

Generation time
~5–14 seconds
