We reran our prior eval but focused only on intelligent routing to models from frontier labs. tl;dr you still get massive cost savings at virtually identical correctness AND actually have lower latency.

We just keep shipping cool stuff 😎 It was fun helping out team with information retrieval metrics and experimentation—they rocked!
Introducing Merge’s Universal Context Layer. It substantially decreases token cost while increasing accuracy. Every company uses AI wrong: Say your designer makes a deck using Claude. They teach Claude your design systems and typography. Now a Marketing hire makes a deck. None of the information your designer taught Claude gets passed over… why? Merge fixes this: All knowledge and memory across your entire company gets stored inside our context layer. When someone on the org teaches Al, that skill lives across the entire organization instead of staying locked in their session. Your AI runs faster, cheaper, and with more accuracy. You don’t have to switch systems, incur more costs, or retrain anyone on your team, Merge runs invisibly in the background. Book a demo here: merge.dev/merge-for-workforc…

Since I’m Max and this is Max the Hedgehog, I’m now in my Max-maxxing era 😲 Thanks to @minchev and @danielyegarcia for the hookup!

This year we’ve all heard stories about blowing past AI budgets, allowing agents improper app access, and fighting against drifting output quality. The solution? Merge for Workforce.
We just cut AI spend by 75% across an entire workforce in one click. Introducing: Merge for Workforce. Without Merge, your employees are left choosing one of two options: 1. Spend 100x the cost they should be from using frontier models for everything 2. Deliver subpar work from overly restrictive model access Instead with Merge, IT can connect any identity provider and set model routing policies by team in one click. Merge pushes them to every machine through a desktop client, overriding the model configs across your team’s AI assistants and coding tools. Now every task gets the right model for the job. The result? 75x fewer tokens with faster and better output.

We do have a legendary view - I can see Coit Tower and East Bay from my desk!
Bumped into @merge_api CTO @GilFeig on the street and asked him to show me his office… here’s how it went

A lot of companies founded pre LLM explosion have struggled to find PMF by tacking on AI features that customers may not care about or want. Check out what Merge has done to build meaningfully in the space - you'll learn a ton from @shensi! xitter.cf/TurnerNovak/status/208…
New @ThePeelPod with @shensi Most founders get one founding story. Shensi thinks @merge_api has three. Shensi and @GilFeig started Merge in 2020, watched their first customers die, then rebuilt themselves twice for the AI era. Not many founders talk this honestly about tearing up their company. A lot of lessons for others trying to do the same. We get into why integrations turned out to be so important in AI, the playbook behind their night-shift 5-11pm AI transformation, almost hiring a foreign spy, why founders with an EA are moving too slow, the Embarrassment Framework, vibe coding a dinner bot that 10x'd their customer events, and why 6% of Merge employees get married.

Over the last month, I've spent a lot of time working on and thinking about AI evals. Here are some of the harder, less obvious lessons:

Much of my career in data has been understanding what people are actually trying to do. The same applies here: ground eval prompts in real use cases and failure modes, not hypotheticals. Customer feedback, support tickets, and dogfooding beat guesswork.

If you've made it this far down, hopefully you get a sense for how nuanced evals work is. It's foundational to product quality in this AI era and the only way to know if your offering is good in production instead of some nice looking demo.

Opinionated tools from Merge FTW 🙌
high quality connectors cut an agent's work in half. using the same model and the same task, an agent running on @merge_api's connectors finished in 5 turns where public MCP servers took 10. connectors are our specialty, so every one is continuously maintained and regression tested against the live API. merge.dev/merge-agent-handle…
