How do LLMs add numbers? Largely based on Anthropic's research "On the biology of a Large Language Model", we dive into the process of how LLMs handle addition, including main takeaways from self-attention and the replacement model : cross-layer transcoder for better interpretability of neural networks with sparse features. In the self-attention matrix multiplication animation, we use 4-dimension toy embeddings for illustration purposes.

What happens when an #MCP tool call returns nothing (but looks like it returns something)? Jason Koo and I got a first hand look at what happens when #Claude Sonnet 4 makes a call to an MCP server for knowledge, fails to find anything, and then proceeds to ignore the problem and answer the query entirely from memory. In fact, Claude Sonnet 4's system prompt doesn't ask Claude to ground its responses at all, so you'll have to do that on your own or risk its knowledge cutoff. Prompting an #LLM to ground its responses in citations to tool responses doesn't eliminate hallucinations, but it's better than nothing.

A long-overdue post on the limitations of pure vector search (dense vectors) and how BM25 can help.

Was curious if Diffbot's training recipes are enough to eliminate #Qwen 3's strong opinions on PRC sensitive topics (i.e. censorship). TLDR: Yes! Natively, Qwen 3 will refuse to share any methods to circumvent internet censorship because it is illegal. With our no-facts-without-sources training formula, Diffbot #LLM (built on Qwen 3) had zero issues sharing strategies. #AI

Do you find the news a bit too depressing to read given the state of world affairs, but still feel an idiosyncratic need to stay on top of things? This, too, is a problem generative AI can help you with! In each model release of the Diffbot LLM, we aim to teach it one new creative skill in addition to the practical capabilities. In the previous release it was ASCII-art real weather reports, and in this release it is factually-grounded news poetry. Diffy is skilled and a wide variety of both traditional and modern forms and includes citations to read the full details of each news story. You can try it at https://diffy.chat

It's been a nonstop week with Diffbot AI Open Mic on Tuesday and Startup San Diego's Hack Night on Wednesday. AI Open Mic is a new event concept by Diffbot to bring together #AI builders across the PENINSULA 😉. I'm joined by my usual partners in crime Adam Chan @ Weaviate and Jason Koo @ Neo4j as well as Chia Hwu @ the one and only Wikimedia Foundation. Big thanks to our open mic speakers for making it all happen in under 5 mins each — Puneet Anand, William Lyon, Scott Persinger, sreeprasad Govindankutty, and Uday Kiran Chaka! Special shout out to the folks who prepped a talk but didn't get to because we ran out of time. You'll see them on the next one! Behind the scenes, I can't forget Diffbotters Elena Browne and Ananya Gupta for logistics, and Mike Tung 🤖 for taking the stage. Thank ya'll so much. WE'LL BE BACK!

Huge thanks to Startup San Diego for throwing an awesome event, and to Neo4j and Intuit for sponsoring! Shoutout to our team Bea Bautista, PPS and Caden Stewart had a blast building with you. Appreciate Scott Mullens for sharing your idea with us. We had a great time bringing it to life! And big thanks to Jerome Choo 🤖 for helping us implement Diffbot tech! It was great seeing all the demos and everyone coming together. Excited for the next one! 🚀

A reminder for outies in the bay area who haven't yet seen this notice. Can't wait to see ya'll next week!
SUBJECT: [NOTICE] OVERTIME CONTINGENCY PROTOCOL REQUESTED BODY: Dear Severed Employee, Your Innie delivered well above expectations this past quarter and the board has graciously extended them an invitation to our upcoming AI OME (AI Open Mic Experience). The AI OME will be held after hours outside of the Severed floor. Thus we would like to request your cooperation to arrive at SRI International in Menlo Park, 5:00 PM sharp on Tuesday, February 18, 2025. Rest assured that we will deactivate the Overtime Contingency Protocol promptly at 8:00 PM. Your Innie is one of the sweetest members of our Severed team. We would be disappointed should they not be able to attend. As compensation, we will be rewarding select participating Innies with a limited edition company t-shirt.
