00:00A new language model, Zephyr 7B, has arrived, and it's doing something remarkable.

00:05It's actually performing better than ChatGPT in some key tests, which is pretty impressive.

00:10So it's a model with 7 billion parameters designed to be a helpful assistant.

00:15Zephyr 7B was developed by the Hugging Face H4 team,

00:19who are known for their amazing work on transformers and other open-source AI projects.

00:24They used a mix of publicly available and synthetic datasets to train Zephyr 7B.

00:30And they used a novel technique called Direct Preference Optimization, or DPO for short.

00:36DPO is a way of fine-tuning language models based on human preferences rather than labels or rewards.

00:42Basically, they used another powerful language model like GPT-4 or Claude

00:47to rank the outputs of Zephyr 7B and compare them with other models.

00:52Then they used a reinforcement learning algorithm to optimize Zephyr 7B based on these rankings.

01:00This training method is pretty innovative.

01:02It doesn't need human annotations or feedback, which are hard and costly to gather.

01:06It also lets the model learn from a wider range of data, not just limited to specific tasks.

01:12And the great thing is, it's proving to be very effective.

01:16So how effective is it?

01:17The Hugging Face H4 team shared some results in their paper.

01:21They tested Zephyr 7B on MTBench and AlpacaEvil benchmarks.

01:26MTBench checks how well the chatbot can follow instructions and converse,

01:30while AlpacaEvil uses human preferences to rate chatbot responses.

01:34On both benchmarks, Zephyr 7B beat ChatGPT by a significant margin.

01:39On MTBench, Zephyr 7B scored 0.82 out of 1, while ChatGPT scored 0.67.

01:47On AlpacaEvil, Zephyr 7B scored 0.77 out of 1, while ChatGPT scored 0.63.

01:55These are huge differences, especially considering that ChatGPT is already a very impressive model

02:01that was trained on millions of real-world dialogues.

02:03Zephyr 7B is better than ChatGPT for a few reasons.

02:08First, it's bigger, which means Zephyr can hold more information and understand more complex ideas.

02:13Also, it's built differently.

02:15The way Zephyr 7B learns is really important, too.

02:18It uses Direct Preference Optimization, DPO, to get better based on what humans like,

02:24while ChatGPT improves using supervised fine-tuning, which depends on specific labels or rewards.

02:30DPO lets Zephyr learn from a wider variety of examples and focus on what people actually want,

02:37instead of just trying to meet a set goal or reward.

02:40Because of this, Zephyr 7B can give more useful, clear, and relevant answers than ChatGPT in many situations.

02:48For instance, if you ask it to write about cats,

02:51Zephyr 7B can create a detailed, well-organized essay about different things related to cats.

02:57ChatGPT might just write something more basic and repetitive about how cute cats are.

03:03When explaining complex topics like quantum mechanics,

03:06Zephyr 7B can give a straightforward and easy-to-understand explanation with simple examples.

03:12ChatGPT might end up giving a more complicated and confusing answer with lots of technical terms.

03:18In casual conversations, Zephyr 7B comes across as friendly and natural, showing humor and empathy.

03:24ChatGPT, however, can seem more stiff and sometimes gives odd or unrelated answers.

03:30These examples just scratch the surface of how Zephyr 7B is better in different ways.

03:35You can find more examples on the Hugging Face website,

03:38where you can also test out Zephyr 7B yourself with your own questions.

03:42Now, I believe we're entering a new phase where language models are more than just text generators.

03:48However, Zephyr 7B isn't without its flaws.

03:51It has its own set of challenges, like dealing with biases and inconsistencies

03:56that might affect how well it works and how much you can rely on it.

04:00It also struggles a bit when trying to scale up, which could hold back its performance and effectiveness.

04:05Plus, it needs more data and feedback to get better at handling different situations and being more reliable.

04:12But these challenges aren't impossible to overcome.

04:15They're actually chances for more research and improvement.

04:18I'm confident that the team at Hugging Face H4 and the broader AI community

04:22are going to keep pushing to enhance Zephyr 7B and other language models.

04:27That's all for today's video.

04:29I hope you found it interesting and learned something.

04:37I'd love to hear what you think about Zephyr 7B

04:39and how you might use it in your projects or everyday tasks.

04:42Thanks for tuning in, and I'll catch you in the next one.
