We split our work: * Specification extraction. We have security.md and policy.md, often per module. Threat model, mechanisms, etc. This is collaborative and gets checked in for ourselves and the AI. Policy is often tricky & malleable pr

In our evals for answering cybersecurity incident investigation questions and even autonomously doing the full investigation, gpt-5.2-codex with low reasoning was the clear winner over non-codex or higher reasoning. 2X+ faster, higher compl

I find it confusing in most directions. Ex: For the above statement, if they're truly dishonest brokers and openly ignore the rules that are inconvenient, they would have zero problems agreeing to Anthropic's terms and then violat

New funding round investors generally get seniority over old But new money may allow buyouts of existing at that time so early team or investors can cash out a bit early And common doesn't cash out till IPO or private market equivalent

My intuition is it comes down to error-correcting codes. We're dealing with lossy systems that get off track, so including parity bits helps. Ex: <message>...</message> helps keep track. Even better? <message78>.

This feels right in theory and wrong in practice When measuring speed running blue team CTFs ("Breaking BOTS" talk at Chaos Congress), I saw about a ~2x difference in speed (~= tokens) for a database usage between curl (~skills) v

We do a fun variant of this for louie.ai when working with database and especially log systems -- think incident response, SRE, devops, outage investigations: instead of returning DB query results to the LLM, we create dataframes (think in-

I've been calling this Software Collapse, similar to AI Model Collapse. An AI vibe-coded project can port tool X to a more efficient Y language implementation and pull in algorithm ideas A, B, C from competing implementations. And anot

Bandwidth-wise, it's fun when you have a storage array instead of just 1 nvme. Then you can saturate the pcies, and go beyond what's cost effective on ram. Interesting to think of this as opening the door to 10-100T MoEs..

This is exactly what I was wondering I gave a talk a few years ago at dask summit (conf?) on making the stars align with dask-cudf here. We were helping a customer accelerate log analytics by proving out our stack for nodes that look roughl

Interesting, a lot of this is consistent with our experience! We've been adding linters, including semantic analysis, in various ai talk2db connectors in loiue.ai that help steer better than normal thin MCPs enable. We've been hav

Performance. Our code looks like pure pandas (fancier SQL) wrapped as HTTP service (arrow instead of json), so the expressivity is more of a step backwards. We already did the work of turning awkward irregular code into relational pipelines

For graphistry at least, I care less about the surface syntax (async/await) and more about getting gpu-side work stealing, dynamic task scheduling, etc. Our code is written at such a much higher level that these are primitives needed b

We have been curious about this for rapids cudf. We built the graphistry stack 10 years ago (!) for GPU native end-to-end acceleration - data loading, wrangling, analytics, enrichment, viz, etc, all the way server GPUs to client GPUs - but

We had a measurable shift when we started doing ai-coding loops driven by evals. By definition, the additions make the numbers go up-and-to-the-right. It's the epitomy of "you get what you measure" :) Chaos Congress talk on t

We contributed the first JS impl and were helping with the nvidia gpu bits when it was starting. Some of our architectural decisions back then were awful as we were trying to figure out how make Graphistry work, but Arrow + GPU dataframes r

I get ai-adjacent dev teams going all in, as they're equipped to deal with the hard edges, but this is brutal for everyone else. Like Frank in collections is just trying to make sure people get paid, not worry about whatever it means t

Pass as immutable values, and try to enforce schema (eg, arrow) to keep typed & predictable. This is generally easy by ensuring initial data loads get validated, and then basic testing of subsequent operations goes far. If python had de

I have been curious on secure base images for the AI ecosystem, where we need to ship with cuda 11.8/12.8/13.1 for stability reasons, and in our case, a bit of the torch ecosystem and Nvidia rapids ecosystem. That ends up being...

RIP low-code, long live low-code companies :) For our startup, the low-code vs LLM shift started hugely frustrating and scary, but also hopeful. After years of dev, we were getting ready to launch our low code app product #2, and then bam,

Yep! One of my favorite attacks is just having a very long piece of a text so the LLM becomes unclear what's important and is happy to do something else

I don't know at these scales, but at the 1M-100M, we found switching from out-of-box embeddings to fine-tuning our embeddings gave less of a sting in the compression/recall trade-off . We had a 10-100X win here wrt comparable reca

Fun! I was curious given the cloud discussion - a quick search suggests default AWS SSD bandwidth is 250 MB/s, and you can pay more for 1 GB/s. Similar for s3, one http connection is < 100 MB/s, and you can pay for more pa

Apache arrow is great here, basically the reason we wrote the initial js tier is for easier shuttling from cloud GPUs & cloud analytics pipelines to webgl in the browser
