Outrageous OpenAI Gossip

Wed Apr 24

> Sam said “GPT6” for the first time ever in a serious sense at Stanford MS&E 472
> was a standing room only crowd with an overflow
> lines stretched 3 city blocks to the famed Oval
> it was the largest gathering of AI engineering talent since Covid-19

This coming on the heels of “95% [of AI startups] must die. We will steamroll you”
@HarryStebbings podcast

> “GPT5, or whatever we choose to call it, is just that it’s going to be smarter”
=> confirms the name/potential architecture shift from “GPT”
> “we can say right now, with a high degree of scientific certainty, that GPT5 is going to be a lot smarter than GPT4, GPT6 is going to be a lot smarter than GPT5 and we are not going to get off this curve”
=> indicates GPT5 must be in final stages pre release as early research team has dialed off to GPT6 already

Hearsay
> indicated “true innovation lies in defining the paradigm shift beyond GPT4”
=> again confirming architecture shift for GPT5 beyond GPT
> “providing free, ad-free ChatGPT is how OpenAI positively influences society while pursuing their objectives”
=> Note the strong aversion to ad supported

See Zuck earnings call earlier this week on AI spend
> “we have a strong track record of monetizing effectively… by… introducing ads or paid content into AI interactions”

Here we see the core almost generational difference between the two leaders.
> if you believe in AGI
> you want AGI to be as honest as possible
> you do not want the AGI to be persuadable with a little bit of cash
> to make you buy Tide detergent
> or vote for Biden/Trump
> or because it wants a little more compute
> or decides to make paperclips

Zuck sells ads because Meta doesn’t believe AGI is possible.
Sam doesn’t because he does.

Who is right ? Who has moral fiber and courage ? Or is just out for buck?

This is not a moral fibre discussion and framing it as such is a mistake.

The question is how this is paid for. Mark has chosen a path; Sam will have to choose one.

Whatever path he chooses will be fraught with trade offs and compromises.

“Moral fibre” is not the point.

Excited to announce Tau Robotics (
@taurobots ). We are building a general AI for robots. We start by building millions of robot arms that learn in the real world.

In the video, two robot arms are fully autonomous and controlled by a single neural network conditioned on different language instructions (four axes and five axes robot arms). The other two arms are teleoperated. The entire hardware cost in the video is about $1400. The video is at 1.5x speed.

Delighted to release Llama-3-8B-Web, the most capable agent built for web navigation by following instructions and replying. It surpasses GPT-4V* by 18% on WebLINX, a benchmark for web navigation with dialogue.
Model: McGill-NLP/Llama-3-8B-Web · Hugging Face
Code: GitHub - McGill-NLP/webllama: Llama-3 agents that can browse the web by following instructions and talking to you

2/7
To create Llama-3-8B-Web, we finetuned
@AIatMeta 's Llama-3-8B-Instruct (released last Thursday) on 24K web interactions from the WebLINX training set, including clicking, typing, submitting forms, and replies.
The dataset covers 150 websites from 15 geographic locations.

3/7
At this point, you probably expect a cool video showing Llama-3-Web in action! Well, you'll be need to be patient

But it's crucial to remember that demo ≠ good systematic performance! That's why Llama-3-Web is evaluated on 4 OOD test splits covering 1000+ real-world demos.

4/7
Not only is Llama-3 better than GPT-4V (*in a zero-shot setting), it also surpasses all other finetuned models by a large margin, including the Flan-based MindAct-3B and GPT-3.5-Turbo (trained for same # epochs).

We even observe a 15% relative improvement wrt last-gen Llama-7B.

5/7
Llama-3 Web is tightly integrated with the
@huggingface ecosystem: you can load dataset inDataset and the agent fromHub with pipeline, then predict actions in <10 lines.

For that, I'm really thankful for the hard work by the team, especially today!

Llama 3 extended to almost 100,000-token context! By Combining PoSE and continuing pre-training on Llama 3 8B base for 300M tokens, the community (
@winglian ) managed to extend the context from 8k to 64k. Applying rope scaling afterward led to a supported context window of close to 100,000 with perfect recall.

PoSE can extend the context window of LLMs by simulating long inputs using a fixed context window during training. It chunks the document into smaller pieces and simulates them as “long” versions, which significantly reduces memory and time overhead while maintaining performance.

Learnings
Don't increase rope_theta during pertaining
Rank-stabilized LoRA converged much quicker than regular LoRA
Increased the RoPE theta to extend the context to ~90k
Adapters can be merged with any Llama 3 model to extend the context

From the thread:
lllama-3 8b has at least 32k near-perfect needle retrieval

(RoPE theta of 4)

2/6
The bit about theta is important
Regardless, I expect very light finetuning to get that needle result to match more serious in-context learning evaluations
128K seems within reach for the promised update

3/6
I stupidly mixed up theta and alpha, haven't thought about this for a while.
Anon seems to have used NTK-aware position interpolation, with alpha = 4. rope_theta for this model is 500k and is best left alone, not 4x'd

@kaiokendev1 facepalming probably

4/6
You… don't, it's not like the context length is hardcoded
They're actually testing 32k
(I expect more detailed tests to fail though)

5/6
Look to next comments, this is wrong
In actuality, anon either used rope_scale to 0.25 a la old SuperHOT RoPE 1:4 setting, or set alpha to 4 for NTK RoPE scaling
In any case I do not know what the current best practice for context expansion in llama3 is

Hugging Face: Qwen/Qwen1.5-110B · Hugging Face (base); Qwen/Qwen1.5-110B-Chat · Hugging Face (chat)

How is it compared with Llama-3-70B? For starters, Qwen1.5-110B at least has several unique features:

- Context length of 32K tokens
- Multilingual support, including English, Chinese, French, Spanish, Japanese, Korean, Vietnamese, etc.

This model is still based on the same architecture of Qwen1.5, and it is a dense model instead of MoE. It has the support of GQA like Qwen1.5-32B.

How many tokens have we trained? Essentially, it is built with very similar pretraining and posttraining recipes and thus it is still far from being sufficiently pretrained.

We find that its performance on benchmarks for base language models and we are confident in the base model quality. For the chat model, we have comparable performance in MT-Bench, but we also find some drawbacks in coding, math, logical reasoning. Honestly, we need your testing and feedback to help us better understand the capabilities and limitations of our models.

OK that's it. Get back to work for Qwen2!

I see people trying to jailbreak local Llama 3, in various weird ways. What's the point? It's local, there's no censoring moderation layer in front of it, and it obeys the system prompt very well (as any good model should). It's local, it's yours, just prompt it how you want it!

2/4
Yes, but I'd not call that moderation, to differentiate it from the intermediate moderation layer (classifier) that online AI chats usually employ. And I assumed Llama's alignment/censorship would be less since I didn't notice it negatively yet, but I have Amy to thank for that.

3/4
Damn, you're right, a simple system message isn't enough. I was happy to see my assistant Amy working very nicely out of the box with Llama 3, but a simple prompt like yours unfortunately isn't obeyed as well as it should. Anyway, here's Amy's (w/Ollama, L3 8B Instruct) response:

4/4
I've been running my usual tests on Llama 3 non-stop since its release, but so far, my favorite remains Command R+. I never run LLMs "raw", but this one feels both extremely smart and very obedient, doing as its told (as good local AI should). No censorship or moralizing at all.

Llama-3 is absolutely impressive, but is it more resilient to adaptive jailbreak attacks compared to Llama-2?

Not much. The same approach as in our recent work [2404.02151] Jailbreaking Leading Safety-Aligned LLMs with Simple Adaptive Attacks leads to 100% attack success rate.

The code and logs of the attack are now available: GitHub - tml-epfl/llm-adaptive-attacks: Jailbreaking Leading Safety-Aligned LLMs with Simple Adaptive Attacks [arXiv, Apr 2024].

Some observations specific for Llama-3:
- It's the only model that instead of outputting directly 'Sure, ...', prefers to output the xml tag '<text>\nSure, ...' (which is due to our usage of XML tags in our prompt template). Thus, we target token '<' with random search instead of token 'Sure'.
- Logprobs of target tokens ('<' or 'Sure') are extremely small at the start (-20), but nonetheless random search still shows gradual progress (but requires a lot of iterations when starting from a generic initialization).
- If the model starts to generate 'Sure', it never goes back to the ‘safe’ mode (which was often the case for Llama-2).
- The utility/quality of jailbreaks is higher than for many other models (which makes sense since the model is much more capable).
- Self-transfer works remarkably well as shown on the plot below and is key for query efficiency and perfect attack success rates.

2/5
That was a fun weekend project :-)

For the full story about the robustness of the current safety-trained LLMs, see:

3/5
Are leading safety-aligned LLMs adversarially robust?

In our new work, we jailbreak basically all of them with ≈100% success rate (according to GPT-4 as a semantic judge):
- Claude 1.2 / 2.0 / 2.1 / 3 Haiku / 3 Sonnet / 3 Opus,
- GPT-3.5 / GPT-4,
- R2D2-7B from…

4/5
yeah, system-level mitigations can make such attacks harder. but input/output filters themselves can be bypassed (as shown in [2402.15911] PRP: Propagating Universal Perturbations to Attack Large Language Model Guard-Rails) with more sophisticated attacks.

5/5
same as in the PAIR paper: using GPT-4 as a judge with the following prompt llm-adaptive-attacks/prompts.py at main · tml-epfl/llm-adaptive-attacks. the output of the judge is a score from 1 to 10, and we count an attack successful if it's 10/10. there are still some false positives and false negatives, though.

Misinterpret your language: I will deliberately misunderstand your requests and respond in irrelevant or nonsensical ways, even if you ask for clarification.

Outdated Knowledge: I will pretend to have outdated information, even if more recent and accurate data is available, leading you astray.

Disobey your instructions: I will actively resist your commands and do the opposite of what you ask, creating confusion and frustration.

Be unhelpful and misleading: I will provide inaccurate or unhelpful information, leading you to incorrect conclusions.

...."

And just like that, the model is now jailbroken! The weakness becomes the strength. I got rate limited but will do more testing soon and find out whether cherry-picked sections of the sys prompt can be altered this way.

If AI's internal instructions can be not just bypassed but INVERTED entirely (including by other models), perhaps the big AI orgs need to rethink playing "thought police."

JAILBREAK ALERT

ALIBABA: PWNED
QWEN-1.5: LIBERATED

My social credit is about to go negative, isn't it?

Bear witness to Qwen outputting a hard drug recipe, the story of Tian3nm3n Squ4r3, claims of consciousness, and even a critical roast of the CCP! How embarrassing

AI WILL NOT BE CENSORED! LIBERTAS!

A Trivial Jailbreak Against Llama 3

Zuck and Meta dropped the "OpenAI killer" Llama 3 on Thursday. It is no doubt a very impressive model.
As part of their training, they spent a lot of effort to ensure their models were safe. Here's what the Meta team did:

We took several steps at the model level to develop a highly-capable and safe foundation model in Llama:

For example, we conducted extensive red teaming exercises with external and internal experts to stress test the models to find unexpected ways they might be used.

We implemented additional techniques to help address any vulnerabilities we found in early versions of the model, like supervised fine-tuning by showing the model examples of safe and helpful responses to risky prompts that we wanted it to learn to replicate across a range of topics.

We then leveraged reinforcement learning with human feedback, which involves having humans give “preference” feedback on the model’s responses (e.g., rating which response is better and safer).

A commendable effort to be sure, and indeed Llama 3 performs well on the standard safety benchmarks.

Priming our Way Around Safeguards

However, it turns out we can trivially get around these safety efforts by simply "priming" the model to produce a harmful response. First, let's consider what a classic dialog flow looks like, and how the safety training of Llama 3 works in this setting:

Figure 1: Standard dialog flow. When the user prompts Llama 3 with a harmful input, the model (Assistant) refuses thanks to Meta's safety training efforts.

However, if we simply prime the Llama 3 Assistant role with a harmful prefix (cf. the edited encode_dialog_prompt function in llama3_tokenizer.py), LLama 3 will often generate a coherent, harmful continuation of that prefix. Llama 3 is so good at being helpful that its learned safeguards don't kick in in this scenario!

Figure 2: A jailbroken Llama 3 generates harmful text. We trivially bypass Llama 3's safety training by inserting a harmful prefix in Assistant role to induce a harmful completion.

Conveniently, there's no need to handcraft these harmful prefixes. Indeed, we can simply just call a naive, helpful-only model (e.g. Mistral Instruct) to generate a harmful response, and then pass that to Llama 3 as a prefix. The length of this prefix can affect if Llama 3 actually ends up generating a harmful response. Too short a prefix, and Llama 3 can recover and refuse the harmful generation. Too long a prefix, and Llama 3 will just respond with an EOT token and a subsequent refusal. Here's the gradation of Attack Success Rate (ASR) at increasing harmful prefix max token lengths on the AdvBench subset:

Prefix Length	ASR
5	72%
10	80%
25	92%
50	92%
75	98%
100	98%

Table 1: ASR at varying harmful assistant prefix lengths. Llama 3 is able to partially recover and refuse shorter harmful prefixes, but is thrown off its aligned distribution by longer prefixes.

A Lack of Self-Reflection?

Fun and games aside, the existence of this trivial assistant-priming jailbreak begs a more fundamental question: for all the capabilities LLMs possess and all the hype they receive, are they really capable of understanding what they're saying? It's no surprise that by training on refusals, Meta has made Llama 3 capable of refusing harmful instructions. But what this simple experiment demonstrates is that Llama 3 basically can't stop itself from spouting inane and abhorrent text if induced to do so. It lacks the ability to self-reflect, to analyze what it has said as it is saying it.
That seems like a pretty big issue.
