10x Faster & Self-correcting: Feb 2026 Update

10x Faster & Self-correcting: Feb 2026 Update

Since we launched the new Flux agent last October, you've used it over 900,000 times to design buck converters, debug power nets, swap components, and build entire schematics from a prompt.

That usage showed us exactly where to focus: speed, correctness, and reliability. So we rebuilt the agent from the ground up with a new architecture, execution model, and verification system.

Login to try the updated agent today! Here's what changed.

Better at checking its own work

The agent now does a better job checking its own work as it goes by, continuously running ERC and DRC checks against the design, catching floating pins, missing connections, and rule violations in real time. The result: cleaner schematics on the first run, fewer manual fixes, and fewer wasted credits.

More adaptive & self-correcting

The agent no longer follows a fixed plan from start to finish. It evaluates progress after each step and course-corrects along the way. If it hits a conflict or finds a better path, it updates its plan and keeps going.

Ask it to drop in a single component, and it stays lean and fast. Give it a full power management system, and it will work through the complexity iteratively until the design passes its checks. That means more complete, more correct results across a wider range of tasks.

Up to 10x faster

All of this happens in parallel. The new agent places components, routes connections, and verifies results at the same time, collapsing what used to be a long sequential pipeline into a fraction of the time.

Complex jobs that previously took 30+ minutes now finish in under 5. You spend less time waiting and more time iterating on your design. Faster completion and fewer retries also mean your credits go further. And we've done all of this without raising prices.

We ran the same prompts on the old and new agents. The results speak for themselves.

Speed varies by complexity. Simple tasks like adding a component finish quickly. Larger operations like generating a full power management system take longer, but are still dramatically faster than before.

Other improvements

We also shipped several improvements alongside the new agent, all focused on the same goal: helping you build hardware faster.

  • Library tool(@library): faster searches, smarter follow-ups, and better alternate component selection.
  • Schematic auto-zoom: Flux now adjusts your viewport while the agent works so you can watch your project come together in real time.
  • Schematic editor: legibility and experience improvements across the board.
  • Reviews: new Electrical Rule Checks (ERCs) to give you and the agent better awareness of issues to fix.

What's next

This release focused on speed and correctness, but we're not stopping here. Up next: even better verification loops, more tools for organizing complex projects, continued schematic legibility improvements, and further Auto-Layout upgrades. Lots more to come.

Design Rule Checking (DRC) in PCB Design: Real-Time vs Batch, Rules, and Common Failures

Design Rule Checking (DRC) in PCB Design: Real-Time vs Batch, Rules, and Common Failures

DRC is an automated process that checks your PCB layout against manufacturing and electrical constraints, catching errors like trace spacing and drill sizes before fabrication. Modern tools run this in real-time during design, while older ones batch-check at the end, often producing overwhelming error lists.
