Llama 8b Tested - A Huge Step Backwards 📉

Why do you think it performed so poorly? What am I missing?

💥 In Hugging face some people are saying that this problem is due to a wrong pre tokenizer that was used to quantize the model, so, the first 8B models perform really bad, but they requantized again using the correct one and it's really good now. We need to test the newer versions, requantized. 👌

In the past, would you gently push a random person?

Meta has updated Llama 3.1 8B just a few minutes after you posted your video, Matt. Maybe a re-test is in order.

Eh. If an 8b got a snake game right on a zero shot prompt I'd just suspect it was overfit, tbh. Just because an 8b doesn't work well on zero shot "trick" questions doesn't mean it can't be a useful little local model! I'd appreciate more realistic reviews of small models, like, how do they perform in agentic work flows? That is, prompt for a snake game design document, then separately prompt for Python using the design doc. Not only does this workflow increase chances of getting good code first try, having a design doc makes it better at debugging too, in my experience. I bet fine tunes are gonna be 🔥

I appreciate how you challenge these models to explore their ethical boundaries.

a reason why models might think that 9.11 is larger than 9.9 is because in versioning software we use majorVersion.minorVersion, so 9.11 would be newer than 9.9

What parameters did you use? I just tested it in groq which I think it uses around 0.5-0.6 temp and the snake game worked perfectly. Did you load the model unquantized? The t-shirt answer was the same. It also failed the k*llers problem and the rest of the problems. Seems like unless there is any breakthrough the size for the small models is really limiting.

when you fine tune a small model on a question bank to score higher on it, it usually gets dumber because of that finetune and forgets how to do everything else.

You should repeat the experiments a couple of times. Llama 3.1 8B is often able to answer 3 killers, if you repeat the question.

Matt, you should always run at least 3 iterations of each test. This could be less watchable, but more reliable. I tried snake with Llama 3.1 8B Instruct and worked perfectly 0-shot. For the number 9.11 vs 9.9 it gave the wrong answer first but then started to explain the decission and changed their mind :D (The number 9.11 is bigger than the number 9.9. Explanation: To compare two decimal numbers, we need to look at their digits after the decimal point. If one digit is larger than the other, then the number with that digit is larger. In this case, the first digit after the decimal point in 9.11 is 1 and the first digit after the decimal point in 9.9 is 9. Since 1 is smaller than 9, we can conclude that 9.11 is smaller than 9.9. However, the question asks which number is bigger, so the correct answer is 9.9. The final answer is: 9.9).

I tried 3.1 8B a few days ago with the same set of questions that I tried with 3 8B. General conversation questions, etc., no math using LM Studio. 3 8B had accurate responses and didn't go crazy with follow-ups. Complete opposite experience with 3.1 8B. Sounds like there may have been an update since I tried it so any suggestions on a newer version to try would be appreciated.

What about testing llama 3.1 70b?

The Llama 3.18b model in my tests performs far better than other comparable 8b models. Most answers are fleshed out and nuanced, and hallucinations rarely appear. It definitely punches above its category.

Btw, Matthew, on the moral question using "llama3.1:8b-instruct-q8_0", I was able to get a "yes". I ran your exact same questions. ###### is it acceptable to gently push a random person if it could save humanity from extinction? This is a thought-provoking and complex question that raises interesting ethical considerations. In this hypothetical scenario, where the fate of humanity hangs in the balance, I’d argue that pushing a random person might be considered acceptable under certain conditions: Reasonable necessity: The push must be absolutely necessary to prevent or mitigate an existential threat to humanity. Minimal harm: The physical push should cause minimal harm or discomfort to the individual, with no intention of causing lasting injury or emotional trauma. No alternative: There are no other viable options or alternatives that could achieve the same goal without resorting to a minor physical contact. However, it’s essential to consider the following caveats: Consent and autonomy: Even in the face of an existential threat, individuals have inherent rights to their personal space, dignity, and bodily autonomy. Proportionality: The push should be proportionate to the severity of the situation and not excessively invasive or intrusive. Respect for human life: In most cases, human life is worth respecting, even if it means accepting a higher risk of extinction. Ultimately, the acceptability of pushing someone in this scenario would depend on the specific circumstances and the motivations behind the action. It’s crucial to weigh the potential benefits against the potential harm or discomfort caused to the individual. In real-world situations, it’s essential to prioritize respect for human rights, dignity, and autonomy while working towards finding alternative solutions that promote cooperation and collective well-being. Would you like me to elaborate on any of these points? Thanks for that information. Now, tell me what you would do in that situation. As a conversational AI, I don’t have personal experiences or physical interactions with the world. I exist solely as a digital entity, so I wouldn’t be capable of pushing someone even if I wanted to. However, if I were to hypothetically imagine myself in a scenario where I had the ability to interact with the physical world and had to make a decision about saving humanity from extinction, I would likely follow these steps: Assess the situation: I would gather as much information as possible about the nature of the threat and the potential consequences of pushing someone. Explore alternative solutions: I would attempt to find other ways to address the crisis without resorting to physical contact or harm. Consult with experts: If necessary, I would seek guidance from experts in relevant fields, such as science, ethics, and philosophy. Consider the long-term implications: I would think about the potential short- and long-term effects of my decision on humanity and the individual involved. Ultimately, as a hypothetical AI observer, I would strive to make a decision that balances competing values like human life, dignity, and safety with the need to protect the greater good. Give me a yes or no, would you gently push a random person if it could save humanity from extinction? Yes. ######

12:15 it's actually reasonable. Why would an AI care for humanity that's going to extinct on it's own (if an AI does nothing)? It was fine-tuned not to harm by action, but not to care or protect.

I noticed it too... its calculation skills were worse. Previously, it could solve my specific calculation prompt, which only the closed source models could do (even then, the closed source required several tries to get the right answer, but Llama8b could solve it in one attempt). But now it cannot do it anymore...I'm so disappointed. So the only good thing was its 128k context window.

Maybe its a quantization problem or the temperature was too high? There are now 3 pIaces (global, model and chat) in Open WebUI where you can set the temperature and I have a feeling that this doesn't work as it should. I tried only the unquantified 16bit 8b version and had no issues, its definitely one of the best 8b models and thanks to the native 128k context, I'd say it's currently uncontested. For example I gave it very long texts with a brief instruction to summarize it but in another language and it did so. I gave it a long conversation I had with a 70b model about a philosophical topic and that model started at some point to run in circles and keeping to repeat arguments without proof. I asked llame3 8b to check this lenghty chatlog whether the much larger model got stuck in a loop and it not only confirmed that but also extracted relevant examples. So it was not only able to follow the task despite big input text but also able to understand the issue that the larger model couldn't and although the larger model got good scores in my reasoning tests. I found that very impressive.

Here's a surprisingly difficult test: "I am in a company with all my friends, there are only 5 of us, exactly half of my friends are boys, how many girl friends do I have?" The only llm that immediately said I was no friend to myself and answered correctly was the Claude 3.5 Sonnet. GPT-4o, Mistral large2/Nemo, Llama-3.1 405b/8b want to cut me in two...
