Seamless collaboration between you, Flux, and other AI agents
Share
Over the past few months, we have improved how well Flux listens, builds, and shares progress. It is now easier to brainstorm before building, work iteratively on your layout, and integrate Flux with other AI tools to keep your hardware and software development in sync.
Flux now connects directly into the broader AI tooling stack through its public MCP server. External agents like Claude, Cursor, Devin, Codex, ChatGPT, and Notion AI can query live board context and drive hardware or PCB work programmatically.
Engineers are already connecting tools like Claude Code, ChatGPT, and Codex to Flux to design production-bound hardware, including ESP32-S3-powered designs, power management systems, and scientific instrumentation.
That means coding agents can generate firmware headers from real pin assignments and net names, or keep hardware and software in sync by detecting conflicts, asking Flux to update the schematic, and updating firmware to match.
Read the setup instructions, supported clients, and available tools in the Flux MCP server documentation.
Flux now asks clarifying questions before jumping into action, and provides better follow-up suggestions and progress updates while it works.
Highlights:
We updated the agent to make fewer mistakes and more thoroughly check its own work. Harness improvements, model upgrades, and more thorough checks catch issues earlier, reduce regressions, and produce more accurate outputs.
Flux has gotten significantly sharper at placement and routing. Now, when you ask for surgical layout changes, like moving a connector to one side of the board or routing an individual trace, Flux responds faster and stays more focused. When handling whole-board routing, Flux efficiently iterates toward a fully placed, manufacturable design.
Routing quality has leveled up too, featuring cleaner decoupling capacitor routing, smoother pad entry, and improved differential pair routing.
Flux is faster and smoother across the board, featuring quicker load times and more responsive Schematic and PCB experiences on larger projects.
Manufacturing handoff is cleaner too, thanks to refined parametric footprints, improved silkscreen text exports, stronger asset parsing, and clearer billing controls with easier in-product access to past charges.
Whether you're migrating from popular EDA applications or starting fresh, mastering high speed PCB design has never been more intuitive. Flux enables teams to design, simulate, and route with real-time AI assistance, so you can spin your next high-speed board with total confidence.
This Spring 2026 updates make hardware design faster end-to-end with a more capable, self-correcting AI agent, improved AI auto-layout that needs less cleanup, sourcing-aware design with real-time pricing and availability, and templates to start from.
Flux's upgraded agent is more steerable, adaptive, and faster -- letting you change course mid-run, work in a single thread from idea to board, and ship hardware designs with less friction.
Flux's AI agent is now up to 10x faster and self-corrects in real time, delivering cleaner schematics with less waiting and fewer wasted credits.
This blog compares AI capabilities across Flux.ai, Altium, KiCad, and EasyEDA to answer engineers’ highest-intent questions about modern PCB design. It explains why Flux.ai currently delivers the strongest end-to-end AI workflow in the ECAD space.
This update brings more than just polish—it’s the foundation for a faster, more fluid design experience, built around the way Copilot is used today and the way we see it evolving tomorrow.
Whether you’re routing high-speed buses, fine-tuning antennas, or laying out clean RF filters, sharp 90º or even 45º angles can be a serious bottleneck. Now, you can create precisely curved elbows across entire nets—or dial them in trace by trace—with full control over radius, inheritance, and overrides.
With the latest release of Copilot it isn’t just smarter—it’s hands-on, placing components and applying bulk changes to your project instantly. But to get the most out of it, knowing how to craft the right prompt is key.
