1. Top-P Sampling

Top-P is another sampling method used by LLMs.

Here’s how it works:

• You let the model choose from words that fall within a cumulative probability threshold.

• Instead of restricting to a fixed number of top words (like in Top-K), Top-P looks at probabilities until the cutoff is reached.

• This makes the text more natural, more human-like, and often more creative.

👉 Last week: I explained Top-K — where you limit the model’s choices to K words.
👉 This week: With Top-P, you don’t limit the number of words, only the probability range.

Why it matters:

• Top-K → great for consistency (predictable answers).

• Top-P → great for fluency and creativity (varied but still coherent text).

Think of it as the difference between confining the model to a small menu (Top-K) vs letting it explore all dishes that meet a certain quality level (Top-P).

I’ve also shared some examples of how outputs shift when switching between these two:

2. ChatGPT GO

Yes — ChatGPT Pro is now available, but only in India 🇮🇳.
Makes sense, since India is the second-largest ChatGPT user base worldwide.

👉 Price: ₹399
👉 How to get it: Go to Upgrade → Select the plan → Pay via UPI

What I’ve tried so far:

1. Projects

   • Independent memory, documents, and instructions grouped together.

   • Useful if you’re working on:

     • a business idea

     • a newsletter (like this one)

     • or even a long-term side project.

   • It keeps context separate so you don’t mix work with personal prompts.

   

2. Image generation

   • Noticeably faster compared to the free tier.

   • Took me under 60 seconds to generate an image.

   • As a free user, the same prompt used to take much longer.

     

💡 Note: That’s my initial exploration. In the next issue, I’ll cover more on add-on features in detail.

3. Formated Excel Output with ChatGPT

This one was a fail (at first).

When I tried asking ChatGPT to make Excel sheets with formatting + formulas, it only gave me raw data — no colors, no fonts, no neat formatting.

Here’s what I figured out:

• You must spell out every detail: colors, fonts, column widths, and formulas.

• If you just say “make it nice,” it won’t.

• The more specific you are, the closer you get to the actual formatted sheet.

💡 I’m still working on this.
If you’ve managed to crack the perfect prompt for formatted Excel outputs, reply back — I’d love to share community wins here.

My prompt for below output - “create a table of SIP of 10K for 15 years in excel with nice formating having blue color and Arial 10 ; formulae of sum should also be there”
