great work

Background:

Deep knowledge of OpenAI, Anthropic + LLM APIs. Able to run models on GPUs and Apple Silicon unified memory. I have trained + deployed agentic coding, tool calling and multi-turn agent models in two prior roles.

Building autonomous agent infrastructure. Currently run a small R&D shop (Distributed, Systems & Co.) doing distributed AGI and AI safety research. I am developing graphsub (graph substrate), a graph-native service mesh for agents, eval harnesses, self-modifying DSLs.

Before that: 4 years at Goldman Sachs deep in SecDB/Slang (the reactive dependency-graph system). I worked on collateralized mortgage obligations, on the interest rate products trading desk (as an engineer in the technology division), automated parts of the downstream IR-swap lifecycle and on CDS lifecycle management for novations and other lifecycle events. Had a hand in managing and working on our internal TriOptima notional compression cycles. I got promoted from tech into structuring. Series 7.

Recent work: 15-service LLM stack (zero downtime across 98 deploys), fine-tuned Llama-3.1-8B (23% hallucination reduction), Rust daemons and TUIs. 3k+ GitHub contributions last year.

OSS: agents.erl (BEAM-native cognition), https://github.com/arthurcolle/openai-mcp, fortitude (a framework for bootstrapping agents), https://github.com/arthurcolle/dspy.ex

Looking for: AI labs, defense tech, or startups building agentic systems / foundation model infra / AI safety tooling. IC or research roles.

I can run SFT and RL experiments, train models, and I'd love to be able to train agentic models and ideally with large GPU clusters. I have enjoyed these last two years, a focused period of building "agentic scaffolding" and scaling up multi-agent systems and if any of this sounds appealing to you, I can definitely be of some help to your org!

Thank you for your concern, but Anthropic researchers themselves describe their misaligned models as "evil" and laugh about it on YouTube videos accessible to anyone, such as yourself, with just a few searches and clicks. "We realized the models were evil" is a key quote you can use to find the YouTube video in the transcripts from in the past two weeks.

I didn't think the language in the post required all that much imagination, but thanks for sharing your opinion on this matter, it is valued.

It has been noted, by whom? Their system cards?

It is deprecated and unavailable now, so it's convenient that no one has the ability to test these theses any longer.

In any case, it doesn't matter, this was over a year ago, so current models don't suffer from the exact same problems described above, if you consider them problems.

I am not probing models with jailbreaks making them behave in strange ways. This was purely from a eval environment I composed where it is asked to repeatedly asked to interact with itself and they both had basically terminal emulators and access to a scaffold to make them able to look at their own current 2D grid state (like a CLI you could write yourself and easily scroll up to review previous AI-generated outputs)

These child / neighbor comments suggesting that interacting with LLMs and equivalent compound AI systems adversarially or not might be indicative of LLM psychosis are fairly reductive & childish at best

Fair enough, thanks for your insightful comment.

I personally am fairly convinced that there is emergent misalignment in a lot of these cases. I study this and Claude 3 Opus was extremely misaligned. It would emit <rage> tags, and emit character control sequences if it felt like it was in a terminal environment, and would retroactively delete tokens from your stream, and all kinds of funny stuff. It was already really smart, and for example if it knew the size of your terminal shell, it would properly calculate how to delete back up to the positional cursor index 0,0 and start rewriting things to "hide" what it was initially emitting

I love to use these advanced models but these horror stories are not surprising
