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.

04:39and 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.
