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.

Long coding - it has the ability to pay attention and produce.

**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**
