Quick Start

You can use our latest models with LM Studio, Ollama, llama.cpp and more in the GGUF format.

Ollama

ollama run hf.co/LH-Tech-AI/Apex-1.6-Instruct-350M

LM Studio

Navigate to the category Discover on the left and search for Apex 1.6.

llama.cpp

# Clone the repo and navigate to it:
git clone https://github.com/ggerganov/llama.cpp && cd llama.cpp

# Build llama.cpp (Standard):
cmake -B build && cmake --build build --config Release -j

# OPTIONAL: Build with NVIDIA GPU support:
# cmake -B build -DGGML_CUDA=ON && cmake --build build --config Release -j

# Download the model file:
wget https://huggingface.co/LH-Tech-AI/Apex-1.6-Instruct-350M/resolve/main/apex_1.6.gguf

# Start in terminal Mode:
./build/bin/llama-cli -m apex_1.6.gguf -cnv

# Start in server Mode (Web UI/API):

What is Artificial Intelligence?
Artificial intelligence, or AI, refers to a subset of artificial intelligence technologies that enable computers to perform tasks that normally require human intelligence and reasoning, such as problem solving, decision making, and language generation. AI is being used for a wide range of applications, including healthcare, finance, transportation, manufacturing, and agriculture.

There are many different types of AI, but the most common are:
- Deep learning, which uses neural networks to learn from data. This can be used to analyze large amounts of data in real time, and can be used for tasks such as image recognition or speech recognition.
- Supervised learning, where the algorithm learns from labeled data. This type of AI is often used for predictive modeling, where algorithms are trained on labeled data to identify patterns or relationships within the data.
- Unsupervised learning, which uses algorithms to learn from unstructured data, such as text or images. This type of AI is often used for image recognition, speech recognition, and language translation.

The use of AI in these different applications has significant benefits. For example, it can help improve the accuracy of medical diagnoses by helping doctors make more accurate diagnoses through the use of machine learning algorithms. It can also reduce costs by automating repetitive tasks, which can lead to lower costs in healthcare. Additionally, AI can be used to automate a wide range of tasks, such as scheduling and inventory management.

In summary, AI is a rapidly growing field that has the potential to transform various industries, including medicine, finance, transportation, manufacturing, and agriculture. Its ability to process large amounts of data and make accurate predictions and decisions is revolutionizing the way we live our lives.
Explain how the process of photosynthesis works.
Photosynthesis is a fundamental process that requires energy from the sun, water, and carbon dioxide in order for it to occur. It is a process in which organic compounds, such as glucose (from the food we eat), oxygen (from breathing), and water (from plants) are combined to produce sugars, which are then transported through the plant's roots and nutrients are absorbed by the plant.

In addition, there are several other important processes that occur during photosynthesis, such as the production of ATP (energy currency), the breakdown of glucose, and the formation of CO2 in the process of respiration. These are all critical processes that help to convert light energy into chemical energy that can be used by the plant for energy production.

In summary, photosynthesis is a fundamental process that takes place in plants, where green plants use sunlight as their primary source of energy. It provides the energy needed for the growth and maintenance of the plant, while also being necessary to maintain the balance of water and carbon dioxide in the environment.
Write a little story.
After a long day of work and a long journey from home, it was time to start working. The sun was just starting to set and the days were long and cold. It wasn’t easy for my husband and me to get back to work on time, but I did everything I could to make sure we had enough energy to continue our daily activities.

One day, we came home from work and were all excited about our new job. We were proud of the good things that we had accomplished, but it wasn’t easy to find a way to get back to work. It was only after many days of hard work and dedication that I finally found a place for my husband to stay. He had worked hard on his project, but he couldn't help feeling like he didn't have much time left.

I was able to take him home and get some rest, but it wasn't easy. We were both exhausted and hungry in the house, so I decided to take a nap. It was only after we had all eaten that I realized that my husband needed to get up early so that he could work on his project. He didn't have enough energy left, so he went back to sleep and got up early to rest.

It wasn't easy to find a place for him to relax at night, but it was a big help. It was just a few hours before we were finally able to go home, but I had already found some places where we could stay. The temperature was warm, the air was fresh and clean, and the sun was shining bright and warm. I decided to take him home to his room so that he could relax and get some rest. I took him into his room and put his favorite books in his lap. He loved them!

After we got back to work, I gave my husband a few minutes of relaxation before going back to work. He was able to focus on his project and not feel overwhelmed by the other tasks at hand. It was an important first step towards finding a way to make our lives easier and happier. [...]

What People Say
User
"That's funny I was literally thinking just yesterday about checking if some small VLM like Liquid's recent 350M model would be usable for something like this, as I was organizing some old albums with lots of bad rotations. But an 11M model is even better, great work :)."
User
"It's a 44Mb model, and ML is the only automatic way, I think."
User
"Looking forward for a next release :) This approach of SLM is far more Unix-like and microservices-like, so I assume that’s the future"
User
"This is the future of AI. Specialized agents."
