Flux + GPT 6 Astra

Start with a complete device specification. Bring the electrical requirements, board interfaces, housing dimensions, and assembly constraints into the same project. Give Copilot a task that connects those requirements, then review the plan with your team. The model choice is part of that conversation; your device requirements set the direction.

Try It Now

Open any project in Flux and launch Copilot. Open the model menu in the composer, find the Preview group, and select “GPT 6 Astra”. Give it a task from your device specification. Start with the power architecture or the machined housing, and include the constraints that connect them:

“Review the power tree and interface requirements for an industrial data acquisition unit. List the design decisions that need my input.”

“Plan a machined enclosure for this unit. Include connector access, mounting points, and assembly order.”

What’s New and Better

GPT 6 Astra is an option in the Preview group. The model menu describes it as “OpenAI's most intelligent model.” Bring that model choice into a workflow built around your hardware project:

• Start with the power architecture and the requirements that govern it.
• Plan the machined housing around the board, connectors, and assembly needs.
• Review the proposed changes against electrical and mechanical constraints.
• Continue the design conversation with the project context in view.

Flux has live context on your design, down to parts, pins, nets, properties, constraints, and stackups. Its automated workflows support stepwise actions, constraint-aware edits, and iterative design changes in your project. You can bring the board and its enclosure into the same conversation instead of treating them as separate designs. A knowledge base of industry best practices and embedded design and process checks adds context for the work. Share your team's requirements so the design plan addresses the device you need to build.

Try It on a Real Design

Try this microphone-preamplifier prompt as a concrete analog design task. Supply the relevant datasheets and ask Copilot for a plan before requesting edits.

Design a low-noise microphone preamplifier for an electret condenser mic feeding a 24-bit ADC. You must calculate the bias network, gain-setting resistors, coupling capacitors, input high-pass cutoff, output anti-aliasing RC, and decoupling layout. Follow the op-amp and microphone capsule datasheets, ADC input requirements, and industry best practices. It will be integrated into a design. Supply: 3.3V analog rail. Mic bias: 2.0 V through resistor, current ~0.5 mA. Target gain: 20 dB to 40 dB switchable. Bandwidth: 20 Hz to 20 kHz. Input noise target: as low as practical. Include pop-suppression considerations and star-grounding strategy.

Then connect the circuit to the mechanical design. Ask for a housing and mounting plan that uses the board outline, component heights, microphone opening, cable entry, and service access. Include the manufacturing tolerances and enclosure bonding requirements in the same plan.

Getting the most from GPT 6 Astra in Flux

• State the input limits. Give supply ranges, interface levels, enclosure dimensions, and mounting constraints.
• Separate the decisions. Ask for a power plan and a housing plan before requesting detailed edits.
• Connect electronics and mechanics. Include the board-to-housing fit and the installation requirements in your review.
• Plan before you act. Review the change plan against your requirements before requesting edits.

Switch Models Any Time

Flux is model agnostic. Copilot gives you the latest models from every major AI lab in one model menu, so you are never locked in to one lab.

Switching is easy. Open the model menu in the composer and select a different model. Your next message uses it, in the same conversation, with the same project context. Use GPT 6 Astra for one task, then compare it with a different model on the next task.

Or let Flux select the model for you. Adaptive gives each task to the model that does that task best for the price. Hard design decisions go to frontier models, and routine work goes to fast, low-cost models. You get frontier intelligence for less: Adaptive is a big part of why Flux is now about 70% cheaper to use. Adaptive is the default choice.

What’s Next

Keep the next step tied to your device requirements. Continue from the power architecture to the machined housing, then review how the two fit together:

• Resolve the remaining power and signal interface decisions.
• Set the enclosure envelope, mounting locations, and connector access.
• Plan the cable paths and the order of assembly.
• Review the complete device with your engineering team.

Open Flux, select “GPT 6 Astra” from the Preview group in the composer model menu, and bring your next design question into the project. Start with one specific change and carry its electrical and mechanical requirements through the plan.
