Different way to compare across parameters, just size it

Your company, your agent.

A few beliefs about building a universal company agent:

1. You should own it, and it should feel like yours.

2. One agent surface. Not a swarm of fake coworkers with personalities and unique capabilities.

3. It should integrate with anything that has an API, not just MCP.

4. Every piece should be swappable for the best in the world at that piece. A full-stack AI platform, not a wrapper.

5. It should run anywhere, from on premises to fully managed. No lock-in.

6. It shouldn't be a framework or an unneeded abstraction. It should be just code you can run, own, and control.

We believe every company will have a central company agent.

Today a company's intelligence is scattered across its tools and the few people who know where everything lives. The company agent changes that.

At Adapt, our job is to build the infrastructure for your company agent.

It's time to build.

Stripe acquiring OpenRouter for $7B+ is great - huge outcome - but I’m most excited to see what @PeterJ_Walker does with Stripe’s transaction data

@PeterJ_Walker Surprised to see so much 4.8 and not a lick of Opus 5

You’ve worked hard to build up your brand, your company AI should continue to use that brand. Own your AI!

[Jim Benton @jim_benton]

We’re moving from asking, “What AI do you use?”
to “What AI does your company run on?”
to “What AI is running your company?”

Today, we’re launching your @ company agent in Adapt. Your company’s own AI, branded with your name and deployable within minutes.

Tag @ yourcompany in Slack and ask it to do the work.

As we go through this change, it is important that a company owns its AI.

Own the agent, @ yourcompany.
Own the knowledge it builds.
Own the model routing.
Own the experience.

The company agent is the durable layer. It gives your company access to the best frontier and open-weight models, choosing the right model for each task to balance quality, speed, and cost.

When you tag @ yourcompany, you’re talking directly to your business through one front door. It learns how your company works, chooses the right model and skill, delegates work to specialized agents, and becomes more valuable as your company’s knowledge grows.

A few things make this possible.

It has to connect to every system your employees rely on, with the right access and permissions to understand the business and take action.

It needs its own secure computer to write code, build apps, analyze data, operate software, and do the work.
It has to be everywhere your people work. Web, Slack, iMessage, GitHub, and more.

Vercel CEO Guillermo Rauch articulated this perfectly when describing @ v, the internal company agent they built.

“If agents become the foundation of modern companies, you being in complete control, from source to runtime to data to token, seems like a pretty big deal.”

Every company will have its own @ company agent.
Adapt is how you deploy yours.

What AI is running your company?

@Caseymanos @gcemaj Good idea

[Jack Welsh @_jacklwelsh]

I wrote up my experiment and the model recipe I'm testing next: https://t.co/YIp2sLdHWq

[Jack Welsh @_jacklwelsh]

I cut my average AI cost per turn by 83% by switching up my Adaptive Intelligence model recipe. The "best" model is subjective, but lies somewhere on the intelligence-to-cost curve - it gives you the most efficient level of intelligence required to complete the task at hand.

@OpenAI Easy to support open source models when you have this up your sleeve - awesome move from @OpenAI

[Jack Welsh @_jacklwelsh]

@Caseymanos Big move from OpenAI. Pricing down the frontier negates a lot of the discussion around open source
