1. Deep Learning
Subset of AI that uses multi-layer neural networks to model complex patterns.
Example: “We applied deep learning to find defects on our production line.”
2. Foundation Model
Large AI model trained on broad data, adaptable to various tasks.
Example: “Our internal search engine is powered by a foundation model fine-tuned on company documents.”
3. Attention
Mechanism that helps models focus on relevant input parts during processing.
Example: “The model used attention to highlight the customer’s complaint buried deep in the email thread.”
4. Transformer
A neural network that uses attention to process sequences efficiently and in parallel.
Example: “We used a transformer-based model to extract action items from call transcripts.”
5. Context Length
The limit on how much the model can “remember” in one go.
Example: “The AI assistant lost track of the conversation because we exceeded the context length after 10 back-and-forths.”
6. Prompting
Providing input to guide an AI model’s output behavior or response.
Example: “We adjusted the prompt to include the target persona, and the ad copy improved instantly.”
7. Fine Tuning
Adapting a pre-trained model to specific tasks using domain-specific data.
Example: “We fine-tuned a foundation model on our support chats so it could handle tier-1 tickets automatically.”
8. Embeddings
A way to turn text or images into numbers that capture meaning and similarity.
Example: “Embeddings helped us find knowledge base articles that matched what the user was typing.”
9. RAG (Retrieval-Augmented Generation)
Combines external document search with model generation to improve factual accuracy.
Example: “Instead of predefined answers, our AI assistant uses RAG to fetch the latest HR policy to give up-to-date responses.”
10. Tokenization
The process of breaking input like text or images into smaller units the model can understand.
Example: “Tokenization split each paragraph into chunks so the model could summarize long PDFs.”
You Should Know: Practical AI Implementation
1. Running a Transformer Model Locally
git clone https://github.com/huggingface/transformers.git
pip install transformers torch
python -c "from transformers import pipeline; generator = pipeline('text-generation', model='gpt2'); print(generator('AI will change', max_length=50))"
2. Fine-Tuning with PyTorch
from transformers import GPT2Tokenizer, GPT2LMHeadModel, Trainer, TrainingArguments
tokenizer = GPT2Tokenizer.from_pretrained("gpt2")
model = GPT2LMHeadModel.from_pretrained("gpt2")
Load custom dataset & train
training_args = TrainingArguments(output_dir="./results", per_device_train_batch_size=4)
trainer = Trainer(model=model, args=training_args, train_dataset=your_dataset)
trainer.train()
3. Extracting Embeddings
from sentence_transformers import SentenceTransformer
model = SentenceTransformer('all-MiniLM-L6-v2')
embeddings = model.encode(["GenAI is transforming industries."])
print(embeddings.shape) Output: (1, 384)
4. Testing Context Length Limits
curl -X POST https://api.openai.com/v1/chat/completions \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model": "gpt-4", "messages": [{"role": "user", "content": "Explain attention in AI."}], "max_tokens": 3000}'
What Undercode Say
GenAI fluency is no longer optional—it’s a competitive necessity. Leaders must grasp these terms to drive AI adoption effectively.
Linux Commands for AI Workflows
