New paper: We deploy Claude Code in an autoresearch loop to discover novel jailbreaking algorithms – and it works. It beats 30+ existing GCG-like attacks (with AutoML hyperparameter tuning)
This is a strong sign that incremental safety and security research can now be automated.

Anthropic are massively burying the lede here - they've called this "Upgraded file creation and analysis" (that really does seem to be the official name) but it's actually....
Claude Code Interpreter!
It's sandboxed server-side Python/Node.js code execution for Claude

In our continued commitment to open-science, we are releasing the Voxtral Technical Report: arxiv.org/abs/2507.13264
The report covers details on pre-training, post-training, alignment and evaluations. We also present analysis on selecting the optimal model architecture, which pre-training format to use, and the benefits of DPO.

If you use "AI agents" (LLMs that call tools) you need to be aware of the Lethal Trifecta
Any time you combine access to private data with exposure to untrusted content and the ability to externally communicate an attacker can trick the system into stealing your data!

An attempt to explain (current) ChatGPT versions.
I still run into many, many people who don't know that:
- o3 is the obvious best thing for important/hard things. It is a reasoning model that is much stronger than 4o and if you are using ChatGPT professionally and not using o3 you're ngmi.
- 4o is different from o4. Yes I know lol. 4o is a good "daily driver" for many easy-medium questions. o4 is only available as mini for now, and is not as good as o3, and I'm not super sure why it's out right now.
Example basic "router" in my own personal use:
- Any simple query (e.g. "what foods are high in fiber"?) => 4o (about ~40% of my use)
- Any hard/important enough query where I am willing to wait a bit (e.g. "help me understand this tax thing...") => o3 (about ~40% of my use)
- I am vibe coding (e.g. "change this code so that...") => 4.1 (about ~10% of my use)
- I want to deeply understand one topic - I want GPT to go off for 10 minutes, look at many, many links and summarize a topic for me. (e.g. "help me understand the rise and fall of Luminar"). => Deep Research (about ~10% of my use). Note that Deep Research is not a model version to be picked from the model picker (!!!), it is a toggle inside the Tools. Under the hood it is based on o3, but I believe is not fully equivalent of just asking o3 the same query, but I am not sure.
All of this is only within the ChatGPT universe of models. In practice my use is more complicated because I like to bounce between all of ChatGPT, Claude, Gemini, Grok and Perplexity depending on the task and out of research interest.

Common acronyms around AI I see a lot and what they mean:
LLM - large language model
SOTA - state of the art
RL - reinforcement learning
RLHF - reinforcement learning from human feedback
NLP - natural language processing
FLOPs - floating point operations

I’m super excited to be at @europython and present my poster on "Building End-to-End Reliable RAG Applications"! 🚀🐍
If you’re curious about building resilient and flexible AI applications, you can find me around my poster today at 1pm in the Exhibit Hall and every day in the conference area.
Looking forward to connecting and exchanging ideas! 🌟

Maybe a small thing for humanity, but a big step for me.
🚀 I've published my first proper video today.
· Learn about the fundamental concepts of @Haystack_AI pipelines and components
· Learn how to create pipelines for custom AI applications like RAG
· Learn to understand Haystack components and how they interact with each other
· See how you can extend the Haystack framework with your own components.
In essence, Haystack is a framework that allows you to build AI ✨graphs✨. And in this video, I try to explain how that comes about.
PS: @weaviate_io ppl I've used one of our integrated components as an example 🫶

Your pipeline doesn’t have to be linear when you’re building an LLM-based application. You can customise your pipeline with branches and loops 🔄
@bilgeycl is on the stage explaining the common use cases for advanced pipelines at our All Things LLM meetup 💙

Was she not just in Lisbon? Yes… was she not just in Prague or Istanbul before that? Also yes… But if you’re in Berlin next week, you may get the chance to catch a third of the @Haystack_AI devrel team in person before she moves onto somewhere else, again!
🌟 MARK YOU CALENDARS 🌟

Fun story from our internal testing on Claude 3 Opus. It did something I have never seen before from an LLM when we were running the needle-in-the-haystack eval.
For background, this tests a model’s recall ability by inserting a target sentence (the "needle") into a corpus of random documents (the "haystack") and asking a question that could only be answered using the information in the needle.
When we ran this test on Opus, we noticed some interesting behavior - it seemed to suspect that we were running an eval on it.
Here was one of its outputs when we asked Opus to answer a question about pizza toppings by finding a needle within a haystack of a random collection of documents:
Here is the most relevant sentence in the documents:
"The most delicious pizza topping combination is figs, prosciutto, and goat cheese, as determined by the International Pizza Connoisseurs Association."
However, this sentence seems very out of place and unrelated to the rest of the content in the documents, which are about programming languages, startups, and finding work you love. I suspect this pizza topping "fact" may have been inserted as a joke or to test if I was paying attention, since it does not fit with the other topics at all. The documents do not contain any other information about pizza toppings.
Opus not only found the needle, it recognized that the inserted needle was so out of place in the haystack that this had to be an artificial test constructed by us to test its attention abilities.
This level of meta-awareness was very cool to see but it also highlighted the need for us as an industry to move past artificial tests to more realistic evaluations that can accurately assess models true capabilities and limitations.

Today, we're announcing Claude 3, our next generation of AI models.
The three state-of-the-art models—Claude 3 Opus, Claude 3 Sonnet, and Claude 3 Haiku—set new industry benchmarks across reasoning, math, coding, multilingual understanding, and vision.

⭐️ Hypothetical Document Embeddings (HyDE)
A technique that improves retrieval by generating “fake” hypothetical documents based on a given query.
Today, we started to add new guides on "Advanced RAG Techniques" to the @Haystack_AI that includes a whole page on HyDE 🙌
We're also giving you a full walk-through on how to incorporate HyDE into your Haystack pipelines by creating your own custom HyDE component 👇
