Sebastian Raschka, PhD's Calm Technical Content Engine

Sebastian Raschka, PhD's Calm Technical Content Engine

I went down a small rabbit hole looking at three very different LinkedIn creators, and I didn't expect the most "quietly technical" voice to be the one that felt the most consistently magnetic. But here we are: Sebastian Raschka, PhD is sitting at 207,032 followers with a 65.00 Hero Score, posting about 2.7 times per week. And it doesn't feel like he's chasing attention. It feels like he's building trust.

What caught my eye is that all three creators have roughly similar Hero Scores (Sebastian: 65.00, Bjion Henry: 64.00, Robbie Simpson: 64.00), but they get there in totally different ways. So I wanted to understand what actually makes Sebastian's content work, and what you can steal from it without pretending to be an ML researcher.

Here's what stood out:

• Sebastian wins with clarity and teaching (he explains the "why," not just the "what")
• He posts at a steady cadence without turning his feed into a content treadmill
• The other two creators show the same engagement strength through business outcomes (Bjion) and leadership narrative (Robbie), which makes the comparison surprisingly useful

The numbers are the first clue: Sebastian's audience is much larger, but his engagement relative to that audience is still top-tier. That usually happens when people save, share, and come back because the content is genuinely useful.

Sebastian Raschka, PhD's Performance Metrics

Here's what's interesting: Sebastian doesn't need daily posting to stay top of mind. With 2.7 posts per week, he's in that sweet spot where each post has time to breathe, but the audience still gets a steady rhythm. And a 65.00 Hero Score at 207k+ followers suggests his posts aren't just getting polite likes, they're earning real attention.

Key Performance Indicators

One more detail I liked: the recommended best time window is early afternoon (14:00-16:00 UTC). For a technical audience, that timing makes sense. People are often in "reading and saving" mode mid-day, not just scrolling before bed.

What Makes Sebastian Raschka, PhD's Content Work

Sebastian's edge isn't a single trick. It's a system that compounds. He teaches, he frames trade-offs, and he keeps the vibe calm and precise (which is honestly refreshing in AI content).

1. He teaches like a researcher, but writes like a friendly engineer

So here's what he does: he takes topics that are easy to overhype (LLMs, scaling, inference costs, new releases) and explains them step-by-step, often with assumptions, small calculations, and "here's the trade-off" framing.

And he doesn't talk down to you. He assumes you're smart and curious, then fills in the gaps that matter.

Key Insight: Write posts that answer the reader's next question before they ask it.

This works because on LinkedIn, most "AI posts" stop at headlines. Sebastian goes one level deeper: what changed, why it matters, and what you'd do differently if you were building something.

Strategy Breakdown:

2. He uses "structured posts" to make hard topics skimmable

Want to know what surprised me? His writing style is technical, but the formatting makes it feel light. Short paragraphs. Clear transitions. Lists that are tight. Labels like "Pro tip:" and "In short," that help you scan.

That structure matters because LinkedIn is a distracted environment. You don't win by being smarter. You win by being easier to follow.

Comparison with Industry Standards:

Now, here's where it gets interesting: if you compare this to the other two creators, the same "structure wins" principle shows up, but it serves different outcomes.

3. He ships "evergreen explanations" alongside timely updates

A lot of creators pick one lane: news commentary or timeless education. Sebastian blends both.

• When the field moves fast, he can comment on releases and trends.
• When the hype gets loud, he can post fundamentals and principles.

And that combination is sneaky powerful. Timely posts get attention now, evergreen posts keep paying you back via saves, shares, and "I followed you because of that one post" moments.

If you're building your own creator strategy, this is a strong template:

1. Post something timely that people are already curious about.
2. Follow it with a foundational explainer that stays useful next month.

4. He sells without sounding like he's selling

Sebastian's headline includes his book ("Build a Large Language Model From Scratch") and his magazine ("Ahead of AI"). But the feed doesn't feel like a billboard.

The pattern is more like: "Here's a useful explanation" then "If you want the full deep dive, here's the link." That ordering matters.

And honestly, it makes the promotional parts easier to trust, because you've already gotten value.

Their Content Formula

When I mapped Sebastian's posts into a simple formula (hook, body, CTA), it looked clean and repeatable. Not flashy. Just dependable.

Content Structure Breakdown

The Hook Pattern

He usually opens by orienting you in 1-2 sentences. No dramatic claims. No "this changes everything." More like a helpful colleague who just learned something and wants to share it.

Template:

"I often get questions about [topic]. Here's how I think about it (and what the trade-offs are)."

A couple variations that fit his style:

"There have been lots of interesting LLM releases lately. Here's what I found most notable (and why)."

"What should we focus on: [option A] or [option B]? Let's assume [simple assumption] and reason it out."

Why it works: it makes a promise you can trust. You're not being baited, you're being invited.

The Body Structure

This is where Sebastian really separates himself. The body is designed for readers who like precision.

Body Structure Analysis:

If you want to copy this without writing about ML, keep the same scaffolding:

• Define the question
• State the assumptions
• Walk through 2-4 steps
• Give a measured takeaway (not a hot take)

The CTA Approach

Sebastian's CTAs tend to be low-friction:

• "Link to the full article: ..."
• "Here's the link to the book: ..."
• "Happy reading!"

Psychologically, this works because the CTA is a continuation of the teaching, not a sudden switch into marketing voice. And if someone doesn't click, they still got something useful.

Notice something? Sebastian's "conversion" is often a long game: readers turn into subscribers, book readers, and quiet advocates. That matches his calm tone.

3 Actionable Strategies You Can Use Today

1. Teach one level deeper than the headline - Add the "why" and one assumption so your reader can follow your thinking.

2. Write for skimming without losing depth - Short paragraphs, clear transitions, and lists that are tight.

3. Use a soft CTA that matches your tone - Offer the next step as a resource, not a pitch (especially if your content is educational).

---

Key Takeaways

1. Sebastian's scale comes from trust - 207,032 followers plus a 65.00 Hero Score tells me people don't just see his posts, they keep them.
2. Structure is the cheat code for technical topics - Lists, labels, and clear transitions make hard ideas feel approachable.
3. Evergreen plus timely is a strong combo - It builds both reach and long-term saves.
4. Promotion works when it's value-first - He earns the click by teaching, then offers the link.

Give one of these patterns a try this week (maybe even at 14:00-16:00 UTC) and see what happens. And if you test it, I'd genuinely love to know what changed for you.
