Why so many LLM projects fail before they begin

The missing link: LLM Training (part 1)!

We’ve noticed a pattern.

A developer wants to build with LLMs. They start with the tools: try a RAG template, play with LangChain, maybe even jump to fine-tuning.

But something feels off. The outputs are shaky. Latency spikes. Evaluating results feels like guesswork. And it’s hard to explain why something works—until it doesn’t.

It’s not a tooling problem.

It’s a mental model problem.

Most devs are jumping into LLM workflows without understanding what’s actually happening under the hood. And without that foundation, even the most hyped-up stack won’t help.

So we made the thing we wish we had:

A clear, practical breakdown of how LLMs generate, reason, and fail—in language built for people who ship.

You can now watch the first session of our LLM Developer Primer for free.

In this first session, we break down:

• How LLMs generate outputs step by step—tokenization, embeddings, attention, autoregression
• Where and why they fail: hallucinations, bias, outdated data, context length issues, logical fragility
• Why prompt engineering works (sometimes), and when you need more serious intervention
• The foundational risks of building with LLMs in production, like prompt injection, data leakage, and cascading failures from unpredictable completions

It’s not a fluffy overview or another marketing webinar. It’s what we wish we had when we were first trying to build serious systems.

If that clicks, the full 10-hour course goes deeper—way deeper.

You’ll walk through:

• Designing end-to-end LLM pipelines, including RAG, prompt architectures, and task-specific fine-tuning
• Evaluating LLMs with automated metrics (BLEU, ROUGE, perplexity) and human-in-the-loop testing
• Understanding agent workflows, tool use, orchestration, and how to manage cost/latency trade-offs
• Applying core optimization and safety practices like quantization, distillation, RLHF, and injection mitigation

By the end, you’ll know how to build, evaluate, automate, and maintain LLM systems that hold up in production, not just on a notebook.
