It's only been a few days since Meta announced the release of Llama 2 and they've already created chatbots where you can try it out.
Most of these chatbots are paid, but here we'll list four free sites for you to test Llama 2 to its full potential.
What is Llama 2?
The Llama 2 is the newest version of Meta company's technical intelligence on a model that can understand human language. It belongs to the broader concept of the Large Language Model (LLM), i.e. the models that deal with understanding and recreating human language.
Llama2 has rocked the LLM world with its outstanding results, and as an open source engine it competes and directly challenges existing leading closed source LLMs such as OpenAI and Anthropic. The first wave of Llama model was good, but Llama 2 is much more powerful and accurate.
What is an LLM?
Το LLM (Large Language Model ) είναι ένα μοντέλο artificialς νοημοσύνης υπολογιστή και προορίζεται να επεξεργάζεται και να κατανοεί τη φυσική γλώσσα. Βασικά είναι εκπαιδευμένο σε τεράστιο όγκο πληροφοριών κειμένου coming from books, articles and web resources, to become familiar with the language examples.
By examining this vast body of text, LLMs foster a deep understanding of sentence structure, terminology, syntax and even emotion, enabling them to produce comprehensive and relevant text output.
The most common example of an LLM is OpenAI's GPT-3 (Generative Pre-prepared Transformer 3), which has garnered extensive attention for its large language capabilities.
GPT-3 consists of 175 billion parameters and has been trained on a huge dataset, constructed from various sources. It is designed to perform language interpretation, question answering, outlining and word processing. Its results are even more difficult to distinguish from human written text. And he also speaks Greek.
Under the hood, an LLM depends on a neural network design known as a “Transformer”. Transformers are made of several layers of attention machinery that allow the model to efficiently handle large sentences and concepts in language. This design enables LLMs to successfully capture text data and understand complex semantic concepts.
What is the Llama Model?
The Llama Model is a large language model (LLM) developed by Meta AI. It is a collection of pre-trained and optimized text generation models ranging from 7 billion to 70 billion parameters. The Llama Model is designed to be used for a variety of tasks including:
- Question answer
- Text summary
- Code generation
- Creative writing
The Llama Model is trained on a huge dataset of text and code, including books, articles and social media posts. This allows the model to learn the statistical relationships between words and phrases and generate text that is meaningful and accurate.
What is Llama 2 and how is it different from its predecessor?
Llama 2 is the latest open source Large Language Model (LLM) released by Meta. It is freely available for both research and commercial use (unless the application / service σας φτάσει τους 700 εκατομμύρια χρήστες).
The model is available in three size variants ranging from 7, 13 and 70 billion parameters. It has been trained on 2 trillion tokens, which is double that of its predecessor, Llama 1.
Llama 2's improved models have been trained on over a million manual – human annotations. Llama 2 greatly outperforms other existing open source models.
Both Llama 1 and Llama 2 do not speak Greek. You can speak to them in English.
Websites to try Llama 2 Models Online and for free:
One of the best and fastest sites to try all Llama 2 models for free is Perplexity Labs. It gives you a simple ChatGPT-like interface where you can ask questions and it will generate the answers. You can select a specific Llama model from the list at the bottom right.
After selecting a model on the bottom right, simply enter a text message and then let it generate the answers for you.
You can keep asking the chatbot questions and it will keep generating the answers. You can ask simple as well as complex questions and the model will handle them just fine.
However, since it's free, the site sometimes takes a while to load.
HuggingChat is a free ChatGPT alternative from Hugging Face. It is intended for running open source models and now supports running the largest Llama model for you.
At this time, you can try the Llama-2-70b-chat-hf model, which is the largest model with the highest accuracy. You can click on the link above and then start asking anything. Enable Web Search for better answers.
So keep using the chat and don't forget to set Llama 2 as the default model for the chat. It will save your chat history like ChatGPT and you can go back to continue a chat. Apart from that, there are some other models it supports besides Llama and you can try them as well.
Hugging Face has a huge collection of AI models for various things. In addition to the official Hugging Chat above, the Llama model with a chatbot is offered by various users on their sites. One of the places that offers the latest Llama 2 mods is ysharma/Explore_llamav2_with_TGI.
You can open this space and then start interacting with the model right away. The model takes a few seconds to load and once it loads, you can enter a text prompt and it will then generate the answer for you.
And in this space, you can try the three Llama 2 models of 7,13 and 70b. This Hugging Face site has also set up these models and you can ask very general and complex questions. However, a slight downside is that if you try to create a long answer, then it can get stuck in the middle. So, try creating questions that involve short answers.
The makers of this site have updated this bot with Llama 2 models. It's a decent free ChatGPT alternative that you can try in your browser with a few clicks. You can use it without registration and currently, it supports the following Llama 2 models.
Testing these models is simple as you just need to visit the main website using the link below. Use the guest mode and then you will be able to access and use the above two models.
It gives you a chat-like interface where you can give it a text prompt and it will return an AI-generated response or text.
In addition to the regular AI chat, here you can enable internet access and even upload a PDF file to chat with it. But these features are experimental.
