Philodendron Rojo Congo is native to South America, specifically regions in Brazil and neighboring countries. Its natural habitat is the rainforests, where it thrives in the warm and humid climate. This philodendron typically grows upright with a bushy habit, making it a fantastic choice for enhancing interior decor or filling a corner that needs a dramatic touch.
Rojo Congo's most notable feature is its deep, velvety, burgundy-red leaves. These large, heart-shaped leaves have a glossy sheen, adding a touch of luxury to any space. The contrast between the red foliage and the plant's green stems creates an exquisite visual display.
As with many Philodendrons, the Rojo Congo contributes to improved indoor air quality by helping to remove common pollutants and toxins, making your home a healthier place to live. It's also considered relatively easy to care for, making it a good choice for both novice and experienced plant enthusiasts.
Philodendron Rojo Congo is not primarily grown for its flowers, and it is relatively rare for it to produce blooms when cultivated as a houseplant. However, when it does flower, the blooms are typically inconspicuous and pale in color.
-
Rojo Congo prefers bright, indirect sunlight, but it also tolerates medium light conditions.It needs at least a few hours of light daily. Avoid harsh direct sun to prevent scorching leaves.
This plant prefers slightly moist but not waterlogged soil. Water thoroughly and drain well after each watering. Check the soil twice per week and only water when the top 1" of the soil is dry to the touch.
Rojo Congo likes rich soil that can retain some moisture, but the soil should also drain well to prevent root rot. It is recommended that you mix some peat with general houseplant soil to improve drainage.
This plant grows best in normal room temperatures (between 65°F-80°F). It does not grow well in temperatures below 50°F and over 90°F. Red Congo thrives in normal indoor humidity, and it is recommended that you mist your plant and use a humidifier when the environment is too dry (humidity level falls below 50%).
This plant should be fertilized once during the growing season (spring/summer) with diluted houseplant fertilizer.
Rojo Congo plant is toxic if ingested, so keep it out of reach of pets and children.

Light on substance and heavy on flaws
Format: Paperback
The book has a great list of topics, but fails to provide much substance any of them.
Most of the provided code is just comments that avoid the actual crux of the issues being discussed. (e.g. #implement the logic to validate XYZ - while the whole point of this chapter is teach how the heck we validate XYZ!)
Some parts are plain wrong, for example the part on Graph based RAG is fundamentally flawed as it assumes the text embedding and the graph embedding are in the same latent space. (This is one of many more examples).
Seems like the book was rushed, and the author has limited hands on experience (if any).
At least we know based on the amount of flaws that it was not written by an LLM

Excellent book to truly understand LLM design patterns
Format: Paperback
I just finished reviewing Ken Huang's pocket book on LLM Design Patterns, and WOW what an amazing resource! This book is excellent if you want to truly understand how to create and enhance intelligent AI language models, all that in your pocket!
Ken makes the difficult things seem surprisingly easy, and that's the real MAGIC.
- How to prepare your data for training by making it extremely clean.
Developing the brains: the practical aspects of training, optimizing, and maintaining your models.
- Learn amazing prompting techniques (such as Chain-of-Thought and Tree-of-Thoughts) to improve your AI's reasoning and problem-solving abilities.
Learn everything there is to know about RAGs so that your LLM can incorporate outside expertise.
- It also delves into creating "agentic" AI that is capable of action and planning (not only simple plan and execute but also enhanced techniques like ReWoo!)
Really, this feels like a useful toolkit, so Ken thank you for that resource
Thanks, Idan Habler

A Broad Overview, But Light on Modern Fine-Tuning
Format: Paperback
I'm currently really interested in fine-tuning LLMs and recently completed my first LoRA-based fine-tuning on a quantized model. I came to this book looking for more detail on fine-tuning. While it touches on the topic, I found the content didn’t quite align with the current state of the field in 2025. Techniques like LoRA, QLoRA, and PEFT weren’t really covered, and the material leaned more toward what I think are older or lower level approaches. That made it harder to connect with what I’m actually working on.
That said, when I shifted to other chapters — like the sections on prompt engineering techniques such as Chain of Thought (CoT) and Tree of Thought (ToT) — I found more value. These sections were clearer, and I picked up a few practical insights, like using few-shot examples that walk through the CoT reasoning process. That’s not something I’ve tried before, and I can see how it might help smaller models that struggle with any type of reasoning tasks.
Overall, the book feels more like a broad overview of all LLM concepts. For someone exploring many topics across the LLM ecosystem, it offers a wide-ranging introduction. But for readers like me who are actively trying to learn and apply techniques like fine-tuning and quantization, it may leave you wanting up-to-date guidance.

Great foundation read for security!
Format: Paperback
This book is a great read! It builds a strong foundation and I would highly recommend it for builders who are interetsed in building on LLMs and ensuring everything is secure. Security is super important and this book does it justice!

Loved it
Format: Paperback
I’ve easily read dozens of tech books. I liked this one a lot. Sure, there were boring parts, but most of it was engaging, especially on dry subjects. I previously read “How AI Works” and found this more informative and way more enjoyable. I got through the 700 pages in about 5 weeks while also learning about probability and linear algebra from other books and online sources. I’d love to read something more advanced by the author, maybe getting into more modern applications. I feel more comfortable with the subject and feel I am now ready to conquer more advanced texts. I initially picked this up to give me some background before reading “How to Build a LLM (from scratch)”. I’ve ordered an intermediary Deep Learning with Python book as well, but wouldn’t mind a more advanced theory book to accompany these books. I’ll definitely be rereading sections of this book to further familiarize myself with topics like backpropagation. Highly recommend if you’re looking for a gentle, but broad introduction to the topic.
