**MODEL ARCHITECTURE**
It is pondered as an endorsed fact that successful LLMs like GPT-4 have been trained using a method called Mixture of Experts due its great performance and higher
efficiency. Thus, we, as EnteliMind trained Enteli-49B using the Mixture of Experts algorithm.
When it comes to improving the quality of machine learning models, scale is key. Given a fixed computing budget, training a larger model for fewer steps is better
than training a smaller model for more steps.An intriguing approach to achieve better scale with limited computational resources is the Mixture of Experts (MoE) model. This method allows for larger models or datasets to be pre-trained using the same compute budget as traditional dense models, but with significantly faster results. Instead of training a single language model where its training would be like a "black box", unaware of its domain-specific abilities, expert models can be separately trained with each expert dedicated to a single ability.
At its core, a MoE model comprises two primary components:
**Sparse MoE Layers**: These replace the usual dense feed-forward network (FFN) layers. A MoE layer consists of several "experts" – each being a separate neural network.
Typically, these experts are FFNs themselves, but they can also be more intricate, even forming hierarchical structures.
**Gate Network/Router:** This component directs specific tokens to specific experts. For instance, one token might be routed to one expert while another goes
to a different one. The routing process is critical in MoE models and is based on learned parameters that are pre-trained alongside the network.
![MoE Layer](https://cdn.discordapp.com/attachments/1016188040978370650/1205151002278232154/image.png?ex=65d75355&is=65c4de55&hm=af4ad6ee9923e999cf3fbd7f6cdc23afdfd093accee59aa1d77d8edab1507daa& "MoE Layer")
**Gating Network Mechanics:**
The gating network's function is to efficiently distribute input across various experts. It's mathematically defined as:
![Gating Network Mechanics](https://cdn.discordapp.com/attachments/1016188040978370650/1205151493603332216/image.png?ex=65d753ca&is=65c4deca&hm=72690eaa46fa311e912a8e7a666424b084ca8377db2f85fb9ce13de3eae693e9& "Gating Network Mechanics")
**Sparsity and Conditional Computation:**
Sparsity in MoE models is about using conditional computation - activating only parts of the network for specific inputs. This approach enables scaling up the
model size without a proportional increase in computation. This is mathematically represented as:
![Sparsity and Conditional Computation](https://media.discordapp.net/attachments/1016188040978370650/1205152780776513588/image.png?ex=65d754fd&is=65c4dffd&hm=ce342d802d162d2617c2d7e56f96cde31f997707eeed5fab4bded77a5396b169&=&format=webp&quality=lossless&width=558&height=158 "Sparsity and Conditional Computation")
Where _y_ is the output, _G_(_x_) is the gating function, _Ei_​(_x_) is the operation by the i-th expert, and _n_ is the number of experts.
**Innovative Gating and Load Balancing:**
Beyond traditional gating, techniques like Noisy Top-k Gating add noise to the gating process, keeping only the top k values. This method, while
introducing complexity, aids in faster training and inference by activating fewer experts. Additionally, noise helps in load balancing, ensuring an equitable
distribution of tokens among experts, preventing any single expert from becoming a bottleneck. Here is its mathematical representation:
![Innovative Gating](https://media.discordapp.net/attachments/1016188040978370650/1205153528146956288/image.png?ex=65d755af&is=65c4e0af&hm=2fc8c56b6ae066b65124d1cde5177466f58379321a7d0763f3e9b87cd788bf10&=&format=webp&quality=lossless&width=1384&height=684 "Innovative Gating")
**Our Research Findings:**
We have simplified our own entire model architecture to the transformer module's mixture of experts known as "MixtralForCausalLM". This allows for easy integration
with the HuggingFace and the transformers module which will certainly facilitate the future work like Supervised Fine-tuning.
However, it is best to acknowledge that the difference between the original implementation and the simplified version is pretty minute and we would like to share our
extra research findings when training Enteli-49B.
**1-) Exponential Mean Absolute Deviation Normalization (EMADNorm):**
Enteli-49B incorporates EMADNorm to normalize the data, which divides each element by an exponential factor dependent on the dataset's mean absolute deviation (MAD).
The MAD and EMADNorm are defined as:
![EMADNorm](https://media.discordapp.net/attachments/1016188040978370650/1205154287857041418/image.png?ex=65d75664&is=65c4e164&hm=477e6af7478bb36d6eb999af3fd6442c54102ccb313cbda1b9ce31a27b57c855&=&format=webp&quality=lossless&width=490&height=160 "EMAD Norm")
Where N is the number of elements, xi is each individual element, μ is the mean of all elements, and e is the base of the natural logarithm.
EMADNorm focuses on the spread of the data by considering the mean absolute deviation. This aspect is particularly beneficial in datasets where the dispersion is an
important feature and needs to be emphasized or normalized differently from the mean. By using an exponential function of the MAD, EMADNorm adapts the degree of
normalization to the characteristics of the dataset. This adaptability can be crucial for datasets with varying levels of volatility or dispersion. Moreover, by normalizing the input data effectively, EMADNorm can contribute to more stable and efficient model training. It ensures that the scale of the inputs does not adversely affect the learning process, which can be critical for the convergence and performance of deep learning models.
**2-) CurveLu Activation Function**
The feed-forward network in Enteli-49B utilizes the CurveLu activation function, a blend of ReLU and Tanh, allowing sensitivity to both positive and negative inputs.
The network can be represented as:
![CurveLu Activation Function](https://media.discordapp.net/attachments/1016188040978370650/1205154792293277787/image.png?ex=65d756dd&is=65c4e1dd&hm=9c8115ea86e746da19ee05860e3aead63b2f4be13c395c446b950bba21fe0405&=&format=webp&quality=lossless&width=798&height=1440 "CurveLu Activation Function")
Where the Curvelu activation function equals to:
![CurveLu Activation Function](https://media.discordapp.net/attachments/1016188040978370650/1205155203079348284/image.png?ex=65d7573f&is=65c4e23f&hm=8057acfc15ae0863bbeb93ba7a47cddde13a9678ee01c0584ff36f3e6fe727e7&=&format=webp&quality=lossless&width=608&height=112 "CurveLu Activation Function")
And _k_ is a hyper-parameter that dictates the steepness of the tanh function or it can be either set as a constant 1.
This novel activation function is both smooth and more forgiving to positive values as it can be discerned from the graph below.
**More Details:**
Enteli-49B is pre-trained on data extracted from the open Web with experts and routers trained simultaneously with over **1.9 Trillions of tokens.**
# Benchmarks
| | Enteli-49B (EnteliMind) | GPT 3.5 (OpenAI) | LLaMa 70B (Meta AI) |
|--------------------------|-------------------------|------------------|--------------------|
| MMLU | 73.6% | 70% | 69.9% |
| HelloSwag (10-shot) | 90.6% | 85.5% | 87.1% |
| ARC Challenge (25-shot) | 87.9% | 85.2% | 85.1% |
| WinoGrande (5-shot) | 83.2% | 81.6% | 83.2% |
| GSM-8K (5-shot) | 61.1% | 57.1% | 53.6% |
These benchmarks indicate that our model **outperforms** models like GPT-3.5 and LLaMa 2 70b although having fewer parameter size.
**Model Usage**
Our model can be easily used with the transformers python library.
The chat template that must be strictly used is as follows:
```
\<s\> [INST] There goes the prompt [/INST] There goes the answer\</s\> [INST] Follow-up prompt [/INST]
```
- \<s\> is the BOS (Beginning of string)
- \</s\> is the EOS (End of String)
Here is an example code for the model usage in python using GPU:
```python
#pip install transformers accelerate bitsandbytes
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM
model_name = "arhanovich/Enteli-49B"
auth_token = "There goes the auth token" #Since this a private model, you must use that auth token to access the model and the tokenizer
tokenizer = AutoTokenizer.from_pretrained(model_name, use_default_system_prompt=False, use_auth_token=auth_token)
model = AutoModelForCausalLM.from_pretrained(model_name, torch_dtype=torch.float32, device_map='auto',local_files_only=False, load_in_4bit=True, use_auth_token=auth_token)
prompt = input("Query: ")
full_prompt = f"<s>[INST] You are a helpful AI called Enteli trained by the AI company EnteliMind.[/INST]\nUser: {prompt}\nAssistant:"
input_ids = tokenizer(full_prompt, return_tensors="pt").input_ids.to("cuda")
generation_output = model.generate(
input_ids=input_ids, max_new_tokens=500)
answer = str(tokenizer.decode(generation_output[0], skip_special_tokens=True)).replace(full_prompt, "")
print(f"Answer: {answer}")
```
**Important Notes:**
- This chat template must be strictly used
- In this code **torch.float32** has been used however, alternatively, torch.float16 could also be used which can lead to faster computations and lower memory usage
but at the cost of precision.
- In this code model has been loaded with **4-bit** which refers to a form of model quantization where the weights of a neural network are represented
using only 4 bits per weight. Quantization reduces the model size and can speed up inference. However, for the sake of precision, it can be replaced with
for example 32 bit which would require more memory and hardware like GPU accelerator.
- Other parameters of the model.generate() such as temperature, top_p, top_k or max_new_tokens can also be altered upon request
**Immediate Integration**
In the dynamic landscape of artificial intelligence, the fusion of Enteli-49B with external functions heralds a groundbreaking era of innovation and utility.
This integration is not just an advancement; it's a revolution, poised to redefine the boundaries of technology and human interaction.
To exemplify, here are some potential use cases of the combination of Enteli-49B with external functions:
- Combining it with a calculator function to enable it carry out flawless calculations
- Combining it with a web browser or a search engine, making it aware of the current data
- Combining it with complex financial calculation tools like market analysis or investment portfolio.
Thus, any API or function in a coding environment can be integrated with Enteli-49B. Things get very interesting when you combine multiple
Enteli-49B with each one having its tools, enabling it to carry out complex tasks that humans are not able to perform efficiently. This can be potentailly
be the dawn of a new form of intelligence.
We, as EnteliMind team, have written two examplar scripts that will be a starting-point of that journey:
**Example1: Integration with functions of Single Paramter**
In the first example script, we are combining Enteli-49B with a **calculator tool** and a **webbrowser**.
Here is the code:
```python
pip install transformers accelerate bitsandbytes duckduckgo_search
import torch
import transformers
model_name = "arhanovich/Enteli-49B"
auth_token = "There goes the auth token" #Since this a private model, you must use that auth token to access the model and the tokenizer
tokenizer = transformers.AutoTokenizer.from_pretrained(model_name, use_default_system_prompt=False, use_auth_token=auth_token)
model = transformers.AutoModelForCausalLM.from_pretrained(model_name, torch_dtype=torch.float32, device_map='auto',local_files_only=False, load_in_4bit=True, use_auth_token=auth_token)
generate_text = transformers.pipeline(
model=model, tokenizer=tokenizer,
return_full_text=False,
task="text-generation",
temperature=0.1, # 'randomness' of outputs, 0.0 is the min and 1.0 the max
top_p=0.15, # select from top tokens whose probability add up to 15%
top_k=0, # select from top 0 tokens (because zero, relies on top_p)
max_new_tokens=512, # max number of tokens to generate in the output
repetition_penalty=1.1
)

This code sets up a basic AI agent. Note that, python libraries such as Langchain or LlamaIndex could also be utilised for building the agent.
Also, the custom cools (and the corresponding system prompt) can be altered for different functionalities.
Also replace the TOOL USAGE part with:
To use these tools you must always respond in JSON format containing `"tool_name"` and `"input"` key-value pairs. For example, to answer the question, "what is the square root of 51?" you must use the calculator tool like so:
```json
{
"tool_name": "Calculator",
"input": "from math import sqrt; output = sqrt(51)"
}
```
Or to answer the question "who is the current president of the USA?" you must respond:
```json
{
"tool_name": "Search",
"input": "current president of USA"
}
```
Remember, even when answering to the user, you must still use this JSON format! If you'd like to ask how the user is doing you must write:
```json
{
"tool_name": "Final Answer",
"input": "How are you today?"
}
```
**Example2:Integration with functions of Multiple Paramters**
In this example, we will be building a Finance Agent that has tools of Compund Interest, Present Value Annuity and Capital Asset Pricing calculation.

For example, to answer the question, "Suppose you invest $5,000 in a savings account offering an annual interest rate of 4%. How much money will be in the account after 10 years if the interest is compounded annually?" you must use the tool like so:
```json

```json
{
"tool_name": "Present Value Annuity",
"input": "payment=1000, rate=0.03, periods=5"

To answer the question "An asset has a beta of 1.2. The risk-free rate is 2%, and the expected market return is 8%. What is the expected return on this asset according to the CAPM?" use the tool like that
```json
{
"tool_name": "Capital Asset Pricing",

**Deployment**
Enteli-49B, a sophisticated AI model, necessitates a minimum of 95GB of VRAM for optimal operation. It functions efficiently on **dual
A100 80GB** systems, where each A100 is equipped with 80GB of VRAM, 117GB of RAM, and 12 VCPUs.
The model is compatible with virtual machines, with affordable options available through runpod.io. On average,
the model processes and outputs a total of 500 tokens in approximately 35 seconds when utilizing a dual A100 80GB setup.
In the context of this model, 'tokens' represent fragments of words. During the initial processing phase, the input is segmented into these tokens,
which may consist of partial words, spaces, or even sub-words. For the English language, a single token is roughly equivalent to three-quarters of a word.
The cost for one-hour usage of a dual A100 80GB system on Runpod is approximately 4 USD. Consequently, processing 1,000,000 tokens (equivalent to around 750,000 words)
would incur a cost of about 75 USD. However, this approach allows for processing only one prompt at a time and presents challenges in GPU management. Additionally,
time-based GPU rental can lead to inefficiencies, as the model may not be in constant use. Thus, employing services like Runpod might not be the most user-friendly
option for consumers.
**Fortunately**, at EnteliMind, we have access to extensive, dedicated computational servers equipped with numerous GPUs.
We aim to offer an API service where you are billed based on token usage. Last month, our usage amounted to approximately 948,750,000 tokens, costing us 7590 USD.
From this data, we deduce that the cost for processing 1,000,000 tokens (about 750,000 words) is 8 USD. Therefore, we are **prepared to offer you our API service**
at a rate of 8 USD per 1 million tokens, subsequent to the purchase of our Enteli-49B AI model.
**Future Work**
The abilities of Enteli-49B can be amplified with these several mathods.
**1-)Building More Complex AI Agents and Swarms**
This is probably the cheapest and the easiest method, though it will produce the best results. The abilities of Enteli-49B could be expanded with many custom tools
(functions) integrated with. This opens wide avanues to the innovation in **finance** for example, combining the AI with any imaginable tool. Another advanced method is
builiding an AI agent swarm where different AIs with their toolsi talk, negotiate with each other to solve pretty intricate problems. This may sound a bit hard to implement
however the projects CrewAI and Autogen have simplified this process immensely.
Langchain: https://python.langchain.com/docs/get_started/introduction
CrewAI: https://github.com/joaomdmoura/crewAI
Autogen: https://github.com/microsoft/autogen
**2-)Fine-Tuning**
Fine-tuning is a crucial step in enhancing the capabilities of pre-trained large language models (LLMs) for specific tasks or domains.
Initially, these models are trained on vast and diverse datasets, equipping them with a broad understanding of language and its various applications.
However, this general training doesn't provide the model with deep expertise in particular areas or specialized tasks.
To address this, fine-tuning comes into play. It involves adjusting the model's parameters further, but this time using a smaller, domain-specific dataset.
This process is akin to giving the model a "mini-education" in a particular field or task, allowing it to become more adept and efficient in that area.
During fine-tuning, the model is exposed to examples that are closely related to the specific task at hand. This exposure helps the model to grasp the
subtleties and nuances of the domain, which might not have been covered during its initial training. For instance, a model trained on a general dataset may
have a basic understanding of medical terminology, but through fine-tuning with medical texts, it can develop a much more refined and accurate understanding of this
domain.
The result of fine-tuning is a more specialized version of the language model, tailored to perform better in specific applications.
It effectively narrows the gap between a general-purpose model and a specialized tool, unlocking new possibilities and enhancing the model's performance in targeted tasks.
This makes fine-tuning an invaluable process for realizing the full potential of LLMs in various domains and applications.
One of the most well-known technique is PEFT (Parameter-Efficient Fine-Tuning). It is a library for efficiently adapting large pretrained models to various
downstream applications without fine-tuning all of a model’s parameters because it is prohibitively costly. PEFT methods only fine-tune a small
number of (extra) model parameters - significantly decreasing computational and storage costs - while yielding performance comparable to a fully fine-tuned model.
This makes it more accessible to train and store large language models (LLMs) on consumer hardware.
