I’ll tell you what it can’t do: compose language in a less sing-song formulaic AI way than existing recent OpenAI models.
What it can do: Simply take a question without needing to be told it is a specialist in a particular area, nor be warmed up with documentation and discussion in the subject area to put it in the correct mindset, nor need example answers and multi-shot just to give the capabilities needed. It is its own prompt engineer.
The AI also has been finally post-trained on being as originally productive as GPT-4 was, without a mind full of curtailed response techniques of prematurely wrapping up responses. It will produce larger structures instead of being a list-maker.
Consider the final response to you as still just one AI looking back as a context. That context may have little solutions broken down that only need to be repeated, or that final AI may need to do the heavy lifting when you can’t really refine on a “creative story” task, nor decide any better not to mix acid, base, and buffer agents together to make an even more effective drain cleaner of salt water.

Identifying the issue
OK, let’s see. The problem involves a series of white TV backlight LEDs with a defect causing one LED to have a 4V forward voltage drop, leading to incorrect voltage and a fault detection in the regulator circuit.
Addressing voltage drop
OK, let me see. The plan is to reroute current around a faulty LED with a resistor to normalize voltage, ensuring the regulator stays clear of fault detection.
Determining necessary steps
I’m figuring out the resistor value to address the higher voltage drop of the defective LED, ensuring it matches normal LEDs while avoiding power dissipation limits and potential damage.
Ensuring operational symmetry
I analyzed the I-V characteristics of both normal and defective LEDs, adjusting voltage drop with a shunt resistor for steadier current flow.
Using the Shockley diode equation for LEDs involves the exponential term, which is often dominant due to the forward voltage surpassing the thermal voltage. Considering the given forward voltage drops at specific currents allows for plotting the I-V characteristics for both normal and defective LEDs.
Calculating the resistor
I’m mapping out the currents and voltages for the defective LED and shunt resistor to pare back the voltage drop, aiming to normalize it to a typical LED voltage drop.
Analyzing circuit dynamics
OK, let me see. The defective LED and shunt resistor are parallel, sharing the same voltage. However, the current from the source affects the entire series string, making it tricky to divert some current away.
Adjusting current paths
OK, let me see: by adding a parallel resistor to a defective LED, I balance the voltage and current. The goal is to match the defective LED’s voltage-drop pattern to the normal one.
Analyzing voltage requirements
I’m working to model the voltage across the node with a defective LED. Here’s the plan: measure the I-V characteristics at both 200mA and 500mA to find a shunt resistor value that keeps the voltage within acceptable limits.
Mapping out voltage and resistance
I’m figuring out how the voltage across a defective LED and shunt resistor matches a normal LED. Ensuring the power dissipation stays within limits with one resistor value is crucial.
Analyzing current flow
I’m examining the voltage across both the defective LED and shunt resistor, ensuring they align with the total current of 200mA. Their voltages match since they are parallel components.

I’m noting the need to choose a resistor value that accommodates acceptable voltage across the defective node at various current levels, while managing power dissipation within a 1W limit.
Assessing the approach
Mapping out the voltage across the defective node, I’m selecting a 20-ohm shunt resistor to match the defective LED’s voltage drop. This should assist in fault detection by the regulator.

Evaluating resistor options
I’m exploring different shunt resistor values for effective voltage clamping across the defective LED. It’s interesting to see that voltage stabilization depends on the defective LED’s current-driving characteristics.
Evaluating solutions
I’m exploring various methods to match the voltage drop across a defective LED. This includes using a resistor shunt, designing a voltage divider, or selecting an appropriate resistor to minimize deviation.
Addressing power dissipation
When the total current reaches 200mA, the power dissipation in the shunt resistor is 0.6W. Raising the shunt resistor to 18 ohms leads to a voltage of 3.6V, potentially acceptable despite being above the normal LED voltage of 3V.
