## How to learn how LLMs generate text one token at a time with LLM Inference Engineering

Repo: [amitshekhariitbhu/llm-inference-engineering](https://github.com/amitshekhariitbhu/llm-inference-engineering) | Difficulty: Beginner | Time: 30 minutes | Basis: From the README

Work through the Part 1 basics on autoregressive generation and the prefill and decode phases.

**Who it is for:** A developer new to LLM serving who needs the core generation loop before reading about optimizations.

**The problem:** Terms like prefill, decode, and autoregressive appear everywhere in inference docs, but they are hard to follow without the underlying loop.

**The outcome:** A clear mental model of the generation loop, the two inference phases, and the metrics TTFT and TPOT.

### Steps

1. Open the Autoregressive Models post at https://outcomeschool.com/blog/autoregressive-models and read the generation loop and the numeric example.
2. Open the Prefill vs Decode post at https://outcomeschool.com/blog/prefill-vs-decode-llm-inference-optimization and read the comparison table.
3. Read the key metrics section on TTFT, TPOT, throughput, and end-to-end latency in the same post.
4. Write a short summary of the difference between prefill and decode in your own words.

```text
Using the amitshekhariitbhu/llm-inference-engineering repo, read the Part 1 section on <topic> and produce a one-page summary of its key terms. Verify that each term in the summary is defined in the linked Outcome School post.
```

### Caveat

The repo is a reading series that links to external blog posts; the README itself contains no code or runnable setup.

## How to pick a KV cache memory technique for long prompts with LLM Inference Engineering

Repo: [amitshekhariitbhu/llm-inference-engineering](https://github.com/amitshekhariitbhu/llm-inference-engineering) | Difficulty: Intermediate | Time: 45 minutes | Basis: From the README

Compare KV cache compression, PagedAttention, GQA, and Flash Attention to choose a memory approach.

**Who it is for:** An ML engineer sizing GPU memory for a model that serves long conversations or many concurrent users.

**The problem:** The KV cache grows with the conversation, and memory waste limits how many users one GPU can serve.

**The outcome:** A short list of which memory technique fits a given serving problem, with the trade-offs for each.

### Steps

1. Open the KV Cache in LLMs post at https://outcomeschool.com/blog/kv-cache-in-llms to understand why the cache exists.
2. Open the KV Cache Compression post at https://outcomeschool.com/blog/kv-cache-compression and read the 'When to use which one' section.
3. Open the Paged Attention post at https://outcomeschool.com/blog/paged-attention-in-llms to see how it addresses memory waste.
4. Open the Grouped Query Attention post at https://outcomeschool.com/blog/grouped-query-attention and compare it with MHA and MQA.
5. Write a table with one row per technique listing the problem it solves and its main trade-off.

### Prompt to paste into your agent

```text
Using the amitshekhariitbhu/llm-inference-engineering repo, compare the KV cache techniques for the workload <workload description> and output a table with one row per technique. Verify that each row matches the 'Comparison of the approaches' and 'When to use which one' sections of the KV Cache Compression post.
```

### Caveat

The README gives explanations and links only; it does not show how to apply any of these techniques to a specific model or server.

## How to choose a faster decoding method for slow responses with LLM Inference Engineering

Repo: [amitshekhariitbhu/llm-inference-engineering](https://github.com/amitshekhariitbhu/llm-inference-engineering) | Difficulty: Intermediate | Time: 45 minutes | Basis: From the README

Compare speculative decoding, Medusa, EAGLE, and n-gram speculation to pick one to study.

**Who it is for:** An engineer whose LLM responses feel slow and who wants to know which speedup approach to investigate first.

**The problem:** Several speculative decoding methods promise faster generation, and each needs different extra parts such as a draft model or extra heads.

**The outcome:** A ranked shortlist of speedup methods with the main requirement and trade-off noted for each.

### Steps

1. Open the Speculative Decoding post at https://outcomeschool.com/blog/speculative-decoding and read the trade-offs section.
2. Open the N-gram Speculation post at https://outcomeschool.com/blog/n-gram-speculation-in-llms and read 'The cost of a draft model' and 'Where it works well and where it fails'.
3. Open the Decoding Medusa post at https://outcomeschool.com/blog/decoding-medusa to see the multiple-heads approach.
4. Open the Decoding EAGLE post at https://outcomeschool.com/blog/decoding-eagle to see drafting at the feature level.
5. Write a ranked list with one line each on the requirement and the main trade-off.

### Prompt to paste into your agent

```text
Using the amitshekhariitbhu/llm-inference-engineering repo, compare the speculative decoding methods for the case <case description> and return a ranked list with requirement and trade-off for each. Verify that every claim about speedup in the list is taken from the linked blog posts.
```

### Caveat

The README reports that methods can give speedups but does not state a guaranteed gain for any particular model or hardware.

## How to understand how LLM servers handle many users at once with LLM Inference Engineering

Repo: [amitshekhariitbhu/llm-inference-engineering](https://github.com/amitshekhariitbhu/llm-inference-engineering) | Difficulty: Advanced | Time: 60 minutes | Basis: From the README

Read about continuous batching, streaming, and disaggregated serving to plan an LLM API.

**Who it is for:** A backend engineer designing an API that streams LLM answers to many users at the same time.

**The problem:** Static batching wastes GPU time, and streaming and separating prefill from decode each add design choices.

**The outcome:** An understanding of how continuous batching, token streaming, and prefill-decode disaggregation fit together in a serving design.

### Steps

1. Open the Continuous Batching in LLMs post at https://outcomeschool.com/blog/continuous-batching-in-llms and read 'The Problem with Static Batching'.
2. Open the How does Token Streaming work? post at https://outcomeschool.com/blog/how-does-token-streaming-work and read 'SSE vs WebSockets'.
3. Open the Prefill-Decode Disaggregation post at https://outcomeschool.com/blog/prefill-decode-disaggregation and read 'Where it works well and where it is overkill'.
4. Write a one-page design note that says which of the three ideas your API needs and which it can skip.

### Prompt to paste into your agent

```text
Using the amitshekhariitbhu/llm-inference-engineering repo, draft a one-page design note for an LLM API serving <number> concurrent users. Verify that the note explains continuous batching, streaming, and disaggregation using only the linked posts.
```

### Caveat

The README mentions vLLM, SGLang, and GPUs only in its description and does not explain how to deploy any of them.
