Hi, I'm Brandon Galang, an applied-AI builder.

I build agentic infrastructure and GTM systems at Vercel. Previously, I led product and data systems across Wonder (Agents + Data), Amazon Ads (ML), and Intel. Outside of work, I also...

Big Tech vs Startups

if you wonder what the difference is between working at big tech and startups, look no further than Google's AI offerings 😐

after getting such great results w/gemini 3.7 flash, i've dusted off my Gemini AI Pro membership. somehow, gemini 3.7 is not yet available in their Jules coding environment.

Model Evals

don't fall for the bait to use gpt 5.6 luna because the benchmarks show its performance is "pareto optimal"

it may perform similarly over a one shot assessment, but luna, terra, and sol are dramatically different in the output tokens and agent steps needed to finish the task.

Model Evals

Ignore the FUD on Gemini 3.7 Flash, it actually sits on the pareto frontier.

5.6 Luna is a much smaller model and while my team cut over production workflows to it, when you factor in raw token throughput, 3.7 Flash is in a league of its own.

Token Economics

openai's 80% price cut actually pareto mogs so hard its absurd

5.6 luna max is literally smarter than opus 5 low and 80% cheaper. with 90% prompt caching, sending a 100k repository map on every turn costs less than a single fresh 10k query.

AI Workflows

If you have ever wanted to build an "AI chief of staff," I strongly recommend giving Dayflow a try.

It captures what you are doing throughout the day and gives you visibility into how you actually spend your time. Visibility is the prerequisite for designing high-leverage agent handoffs.

Model Tier List

here's my AI model tier list as of rn as a gtm engineer at vercel.

this isn't just pure benchmark performance, but how I feel given cost, latency, reliability, usability, etc. also, just pure dopamine per turn. 👑 S TIER: 5.6 sol pro & Gemini 3.7 Flash.

About

I'm an applied-AI builder and GTM engineer at Vercel based in New York City. Previously, I led product and data systems across Wonder (Agents + Data), Amazon Ads (ML), and Intel.

I studied Industrial Engineering at the University of Washington and completed my MBA at Yale University.

I write Leverage Loops to document field-tested mechanisms from lived work: focusing on human control loops, evals, prompt caching, agent constraints, and the human side of autonomous engineering.
