🔗 Paper: https://arxiv.org/abs/1706.03762
━━━━━━━━━━━━━━━

2️⃣ Language Models Are Few-Shot Learners
📝 Description: The GPT-3 paper. One 175B model handles many tasks just by reading prompts — no retraining.
🔑 Key Ideas: In-context learning • Few-shot prompting • Autoregressive next-token prediction
🔗 Paper: https://arxiv.org/abs/2005.14165
━━━━━━━━━━━━━━━

3️⃣ Scaling Laws for Neural Language Models
📝 Description: Showed model performance improves predictably as parameters, data & compute grow. The logic behind going big.
🔑 Key Ideas: Scaling laws • Compute-optimal training • Data vs. model size tradeoffs
🔗 Paper: https://arxiv.org/abs/2001.08361
━━━━━━━━━━━━━━━

4️⃣ Training LMs to Follow Instructions with Human Feedback
📝 Description: The InstructGPT paper. Turns a raw text predictor into a helpful, instruction-following assistant.
🔑 Key Ideas: RLHF • Supervised fine-tuning • Reward model • Human preference ranking
🔗 Paper: https://arxiv.org/abs/2203.02155
━━━━━━━━━━━━━━━

5️⃣ Retrieval-Augmented Generation (RAG)
📝 Description: LLMs fetch external documents instead of relying only on stored memory — great for facts that change over time.
🔑 Key Ideas: Dense retrieval • Document index • Grounded generation • Knowledge-intensive QA
🔗 Paper: https://arxiv.org/abs/2005.11401

Most people confuse AI Agents with Agentic AI Systems! But they’re not the same
👉 AI Agent = single-task executor
User → Agent → Task → Output

👉 Agentic AI System = goal achiever
Goal → Planner ↔️ Executor ↔️ Memory + Environment

When to use which?
✅ AI Agent → summarize a doc, book meetings, extract invoices
✅ Agentic AI → market research, system monitoring, personalized learning

Do these 4 things to 10x your responses while asking for referrals:

1. Be personal. (never use AI)

I get a ton of messages that are either written by AI or obviously copy and pasted to 100 people.

Be personal by mentioning something you have in common with the person you’re messaging or what you got out of one of their posts.

2. Have a specific job that you want to apply for and send the link.

“Can you look and see if there are any openings?” is incredibly rude and inconsiderate of the person’s time.

If you want them to help you with a referral, do the work for them by sending them the link, why you’re a good fit, and other needed info.

3. Reach out to people who are active on LinkedIn, but not content creators.

Everytime there’s an opening at my company, I get 50 messages asking for a referral. As much as I want to, I can’t refer everyone.

Therefore, look for those to connect with at a company you’re interested in that post occasionally on LinkedIn, but are not content creators.

These people will be active enough to see your message, but not have 3 dozen other messages asking for the same thing.

4. Build relationships way before you ask for a referral.

While I don’t do many referrals bc of how many inquiries I get, I’d be much more likely to refer someone who adds to the conversation by commenting on my posts, creates good posts themselves, and overall seems like a smart, nice person.

Doing this turns you from a complete stranger to a friend.

I know a lot of people are pressed for time on here, but building relationships is what networking is all about.

Do that effectively and your network may offer you referrals when there’s an opening.
