Large Language Models for Mortals: A Practical Guide for Analysts

Show original source text →
Shameless promotion -- I have recently released a book, [Large Language Models for Mortals: A Practical Guide for Analysts](https://crimede-coder.com/blogposts/2026/LLMsForMortals). https://preview.redd.it/7t71ql8ek9jg1.png?width=3980&format=png&auto=webp&s=1870a49ec6030cad49c364062c02cf5da166993f The book is focused on using foundation model APIs, with examples from OpenAI, Anthropic, Google, and AWS in each chapter. The book is compiled via Quarto, so all the code examples are up to date with the latest API changes. The book includes: * Basics of LLMs (via creating a small predict the next word model), and some examples of calling local LLM models from huggingface (classification, embeddings, NER) * An entry chapter on understanding the inputs/outputs of the API. This includes discussing temperature, reasoning/thinking, multi-modal inputs, caching, web search, multi-turn conversations, and estimating costs * A chapter on structured outputs. This includes k-shot prompting, parsing JSON vs using pydantic, batch processing examples for all model providers, YAML/XML examples, evaluating accuracy for different prompts/models, and using log-probs to get a probability estimate for a classification * A chapter on RAG systems: Discusses semantic search vs keyword via plenty of examples. It also has actual vector database deployment patterns, with examples of in-memory FAISS, on-disk ChromaDB, OpenAI vector store, S3 Vectors, or using DB processing directly with BigQuery. It also has examples of chunking and summarizing PDF documents (OCR, chunking strategies). And discusses precision/recall in measuring a RAG retrieval system. * A chapter on tool-calling/MCP/Agents: Uses an example of writing tools to return data from a local database, MCP examples with Claude Desktop, and agent based designs with those tools with OpenAI, Anthropic (showing MCP fixing queries), and Google (showing more complicated directed flows using sequential/parallel agent patterns). This chapter I introduce LLM as a judge to evaluate different models. * A chapter with screenshots showing LLM coding tools -- GitHub Copilot, Claude Code, and Google's Antigravity. Copilot and Claude Code I show examples of adding docstrings and tests for a current repository. And in Claude Code show many of the current features -- MCP, Skills, Commands, Hooks, and how to run in headless mode. Google Antigravity I show building an example Flask app from scratch, and setting up the web-browser interaction and how it can use image models to create test data. I also talk pretty extensively * Final chapter is how to keep up in a fast paced changing environment. To preview, the first 60+ pages [are available here](https://crimede-coder.com/blogposts/2026/LLMsForMortals). Can purchase worldwide in [paperback](https://crimede-coder.com/cdcstore/product/large-language-models-for-mortals/) or [epub](https://crimede-coder.com/cdcstore/product/large-language-models-for-mortals-a-practical-guide-for-analysts-with-python/). Folks can use the code LLMDEVS for 50% off of the epub price. I wrote this because the pace of change is so fast, and these are the skills I am looking for in devs to come work for me as AI engineers. It is not rocket science, but hopefully this entry level book is a one stop shop introduction for those looking to learn.

Synthesis verdict
**Pivot**: The book 'Large Language Models for Mortals: A Practical Guide for Analysts' has a strong niche market and solid revenue model, but its longevity and profitability are threatened by rapid API updates and competition from free resources. To succeed, the author should consider tiered pricing, upsell paths, and continuous updates to maintain relevance.

Strengths

  • - Unique, analyst-oriented, hands-on guide with broad coverage of foundation model APIs
  • - Strong revenue model with clear, high-value niche and solid unit economics
  • - Up-to-date examples across major providers (OpenAI, Anthropic, Google, AWS) using Quarto
  • - Clear, growing, and underserved market for practical LLM guides tailored to analysts and non-research engineers
  • - 50% discount code (LLMDEVS) is a smart acquisition hook

Weaknesses

  • - Rapid evolution of LLM APIs risks rendering the book's examples and code outdated quickly
  • - Competition from free/open resources (e.g., official API documentation, community-driven tutorials) could limit paid sales
  • - Narrow target audience (analysts seeking to become AI engineers for a specific employer type) might not be broad enough to sustain significant revenue
  • - Branding ('Shameless promotion') undermines credibility, and domain (crimede-coder.com) feels unprofessional
  • - Limited marketing reach beyond Reddit and niche blogs

Best angle

The book should become a continuously updated, tiered resource with upsell paths, targeting a broader audience of working professionals who need to deploy LLMs in real workflows.

Panel verdicts

Competition

nvidia/nemotron-3-nano-omni-30b-a3b-reasoning

6.0

“Its main advantage is a single, analyst - oriented, multi - provider, hands - on guide that bundles RAG, agents, and LLM - coding tools - an combination few existing resources provide.”

The book targets a specific audience - analysts - and offers a broad, up - to - date, hands - on coverage of foundation model APIs, RAG, tool - calling, agents, and LLM - driven development tools, which is not fully captured by existing titles that tend to focus on developers, data scientists, or generic prompt engineering. However, the market already includes numerous online courses, tutorials, and other books that provide comparable depth on many of these topics, and the rapid evolution of LLM APIs means the book's relevance may decline quickly unless continuously updated. Thus, while the differentiation is genuine in its niche and scope, its durability is limited by the fast - moving technology landscape and competition from free, constantly refreshed content.

Viability

2.0

“The feasibility of building v1 in 4-12 weeks depends entirely on the specifics of the product or service being built in relation to the book.”

The idea is to build a product or service related to the book 'Large Language Models for Mortals: A Practical Guide for Analysts'. The book is already written and available for purchase. The task is to determine if a solo or 2-person team can build v1 in 4-12 weeks. However, the problem statement doesn't specify what product or service is being built. Assuming it's related to the book, potential ideas could be a companion website, a tool, or a course. Without a clear idea of what is being built, it's hard to assess feasibility. If the task is to create a simple companion website with code examples and links to purchase the book, this could be feasible in 4-12 weeks for a solo or 2-person team. However, if the task involves building a complex tool or a comprehensive course, it may not be feasible in the given timeframe. The technical complexity, talent required, and time-to-build would vary greatly depending on the specifics of the project.

Monetization

8.0

“The book's revenue model is solid but could scale further with tiered offerings and ancillary products.”

The book has a clear, high-value niche: practical LLM API usage for analysts and developers, with up-to-date examples across major providers (OpenAI, Anthropic, Google, AWS). The pricing is concrete - paperback and ePub (with a 50% discount code for the latter) - and targets a professional audience willing to pay for actionable knowledge. The conversion path is direct: free preview (60+ pages) to build trust, followed by paid purchase via a dedicated store. Unit economics are strong: digital (ePub) margins are near 100% after payment processing, while paperback margins are lower but still viable. The content depth (RAG, tool-calling, structured outputs) justifies premium pricing, and the Quarto-based updates ensure longevity. However, the revenue model lacks tiered pricing (e.g., bundles, corporate licenses) or upsell paths (e.g., video courses, consulting), which could further monetize the audience. The discount code (LLMDEVS) is a smart tactic to drive early adoption but may reduce perceived value if overused.

Risk

4.0

“Rapid API updates and free resources threaten the book's longevity and profitability.”

The book's technical depth and timely focus on LLMs for analysts are notable strengths. However, its viability as a standalone business venture within the next 6-12 months is threatened by several factors. Firstly, the **rapid evolution of LLM APIs** (e.g., frequent updates from OpenAI, Anthropic, Google, AWS) risks rendering the book's examples and code outdated quickly, necessitating costly and continuous updates to maintain relevance. Secondly, **competition from free/open resources** (e.g., official API documentation, community-driven tutorials, upcoming similar books) could limit paid sales, especially with a 50% discount already offered. Lastly, **narrow target audience** (analysts seeking to become AI engineers for a specific employer type) might not be broad enough to sustain significant revenue. While the author's intent to attract talent is clear, monetizing the book to a wider audience could be challenging.

Market

8.0

“Working analysts and junior AI engineers are starving for practical, code-first, up-to-date LLM guides - and you've built the exact book they need, but haven't yet marketed it to the right professional channels.”

There is a clear, growing, and underserved market for practical, hands-on guides on LLMs tailored to analysts and non-research engineers - not academics, not AI researchers, but working professionals who need to deploy models in real workflows. The book fills a critical gap: most resources are either too theoretical (academic papers) or too vendor-specific (official docs). Your audience is large: data analysts, business intelligence teams, junior ML engineers, and product teams at mid-sized companies using OpenAI, Anthropic, or AWS Bedrock daily. These people are time-constrained, need actionable code, and are willing to pay $30-50 for a reliable, up-to-date reference. The fact that you use Quarto and keep code examples current is a major differentiator - most books are obsolete within 6 months. The inclusion of RAG, tool-calling, agent patterns, and AI coding assistants (Copilot, Claude Code) aligns perfectly with 2025's real-world demands. The 50% discount code is a smart acquisition hook. Weaknesses: The branding ("Shameless promotion") undermines credibility; the domain (crimede-coder.com) feels unprofessional and may deter enterprise buyers. Also, while the audience is sizable (est. 500K - 1M globally), marketing reach beyond Reddit and niche blogs is underdeveloped. If you rebrand with a clean site, run targeted LinkedIn ads to data teams, and partner with analytics bootcamps, this could scale to 10k+ sales. As-is, it's a strong niche product with high perceived value but limited distribution leverage.
