1. I spent a lot of time at scale labeling data myself, never thought it was beneath me. Instead it's how we developed quality criteria, instructions, how we provide partnerships to our customers. My co-founder @flubtitle and I built out new labeling products for LLMs in 2023 (well it's old now) because we did labeling, ran queues (meaning we were running real projects and needed to deliver data). Not because we got a prd from anyone. 2. One of the first things we built at Santori Labs is our voice-first eval/label flow and a roleplay system. I spent hours every week going through data, thinking about what is good vs not. 3. Imagine an engineer who thinks they are too good to do that, but instead they are just here to execute a prd that is given to them. 4. I don't think data is all you should do, but it's still one of the most important things you can do. Labeling is one form, another one is looking at agent traces. If you don't see why that's important, you are stuck in the past. 5. It's painful looking at data. You think you just look at it and you just know if this is good. It's never that. It's always the messy middle of "meh". That's why the design principle for our own data flow is that: data is a focused act, and the product needs to encourage focus
Just learned: Software engineers used to do manual data labeling at Scale AI while Alex Wang was CEO. After he left, new leadership joined, and were HORRIFIED to learn this. Stopped it ASAP Now at Meta, software engineers are assigned manual data labeling... see the pattern?

A behind-the-scenes working session with Tarun Sachdeva (@tarunsachdeva) for an upcoming film collaboration. Tarun is the founder of Traces (@tracesdotcom), a platform for sharing the work you do with coding agents. In this conversation with @internetvin, he walks through what a trace actually is, opening with a single session and pulling on it until the whole product unfolds: profiles, teams, the CLI, integrations, and the discover feed. Timestamps 00:00:00 What is a Trace? 00:06:55 Categorization, Status & How the Summary is Built 00:08:30 The Trace as Atomic Unit 00:10:30 What Happens Between Linear and a Code Base 00:12:55 The Middle Made Visible 00:14:00 Andrew Nesbitt & Everyone is a Beginner 00:18:00 Project Baton: The CLI 00:22:40 Publish, Resume & Git for Agents 00:25:00 Single-Player vs Multiplayer 00:30:00 Integrations: GitHub, Hugging Face & Linear 00:33:50 Why Tarun Stopped Using an Issue Tracker 00:35:00 The Discover Tab 00:37:00 JC, Jake & Reading Other People's Traces

The traces git combination works really well now imagine every commit catching the conversations that generated it, stored as a light reference in a git note and auto-shared and updated as your team rolls once setup you'll see the reference on every session on traces....

Thanks @joshdzieza and the team at @verge for chatting on the state of data spend in AI!
AI companies are spending billions hiring humans to produce training data. @haydenfield and I wrote about the explosion in new vendors and what it means for the future of AI development: theverge.com/cs/features/831…

Final results: 1. @GoogleAI the clear leader with the fastest answer immediately 2. @OpenAI gets us to the right answer but definitely slower and requires follow up 3. @AIatMeta is blazingly fast and the least verbose, but no access to live data

4. @AnthropicAI also unable to get me live data, and a bit oddly asks me for the answer rather than giving me the information I want 5. @MistralAI also unable to get the right answer and a bit slower 6. @xai with no free offering is an immediate no
