CTO + VP Eng briefing 01 / 10

Slide 01

Just Give Me the Best Model.

CTO + VP Eng
Open letter

An open letter to the companies building AI coding tools and the leaders paying for them.

You built something that made software fun again. Engineers who had been at this for twenty years forgot what flow felt like until your tools handed it back. That is real. That matters. Now stop making us think about which model we are on.

The ask Give engineers the best model. Get out of the way. The cost is a rounding error on fully loaded comp. The friction is not.

Slide 02

You Built the Tool That Creates Flow. Why Are You Also Building the Thing That Kills It?

The problem
Three hours in Flow

Engineer and agent are in sync. Architecture is taking shape faster than anyone can type. The tool disappears. It is just the engineer and the system they are designing.

Then your tool intervenes Broken

Too many premium tokens. The agent gets dumber mid-refactor. The context window shrinks. The conversation that felt like a partner now feels like onboarding someone new mid-sprint.

Recovery cost 40 min+

Forty minutes trying to get back to where they were. Sometimes they do not. The flow state is not paused. It is gone. That is engineering output you destroyed.

The thing that felt like a conversation five minutes ago now feels like onboarding a new team member mid-sprint who does not have the context.

What model downgrade actually feels like

Slide 03

Stop Making Engineers Think About Models

UX failure
What engineers do not want

A model picker. A dropdown. A usage dashboard that feels like watching a gas gauge on a highway.

Engineers should not have to decide whether a task is "worth" the frontier model or whether they should save credits for later. They became engineers to build things, not to manage a token budget.

And they really do not want "smart routing" that silently swaps the agent out mid-refactor for a cheaper model and hopes they will not notice. They always notice. The quality drops. The context gets foggy. The suggestions go from sharp to generic.

The routing trap

If I feel the swap, your routing failed.

If you can build routing that is genuinely invisible -- frontier reasoning when the problem is hard, fast-model speed when it is trivial, and the engineer never knows or cares -- ship it.

But the moment the engineer feels the swap, the moment the agent loses the thread of what they were building, they would rather pay for the frontier on everything than deal with a system that drops the ball one time in ten.

The line Your margin optimization is landing on my keyboard as friction. Friction is the one thing your product cannot survive.

Slide 04

Token Anxiety

Behavioral damage
Every pricing tier, every usage cap, every "you have X premium requests remaining" banner is training your best users to flinch. To reach for the cheap model by reflex. To feel guilty about using the good one. To treat their agent like a resource to be rationed instead of a partner to build with.
Flinch

Learned helplessness

Engineers start self-rationing. They reach for the cheap model by reflex, even when the hard problem in front of them needs the frontier. You are training your power users to underutilize the tool they are paying for.

Guilt

Productive guilt

Engineers feel guilty about using the good model. They start treating high-quality output as an indulgence instead of the baseline. This is the opposite of what your product is supposed to do.

Churn

Fastest churn signal

The engineers who will put up with this the least are the ones who churn the fastest. Your best users. Your advocates. The ones who would have sold your tool to their next company. Gone.

Slide 05

Two Kinds of Engineering Leaders. Two Different Conversations.

Market signal

Tiered access leaders

  • They talk about cost.
  • They manage spreadsheets tracking token usage across teams.
  • They run approval workflows for who gets frontier access.
  • Their engineers compare notes with friends at other companies and start thinking about leaving.
  • They are managing a budget line item, not building a capability.

Unrestricted frontier leaders

  • They talk about velocity.
  • They talk about what their teams shipped last week that would have taken a month before.
  • Their engineers do not think about models. They think about building.
  • They are recruiting magnets because word travels fast among engineers.
  • One group is building. The other is managing a spreadsheet.

Slide 06

The Frontier Model Is a Rounding Error on Fully Loaded Comp

Economics
Frontier model cost ~$50-200

Per engineer per month for unrestricted frontier access. The exact number varies by tool and usage. It is not a meaningful number relative to what you pay that engineer.

Fully loaded engineer $15-25K

Per month including salary, benefits, equipment, office space, management overhead. The frontier model is less than 1% of this number. You spend more on their monitor.

Recruiter fee when they leave $30-60K

One resignation. One recruiter engagement. That single fee dwarfs what you saved on their tokens for the entire year. And their friend at another company just told them they have unrestricted access.

The pushback was never really about the money. It was about the unfamiliarity. "AI tokens" did not exist as a line item eighteen months ago, and new line items get scrutiny.

The real source of budget friction

Slide 07

Your Best Engineers Know Who Funds Their Tools With Conviction

Retention risk
The signal your engineers are reading

They compare notes. When a friend says "I just have the best model, I do not think about it" -- that plants a seed.

Your best engineers know who funds their tools with conviction and who funds them with reluctance. They compare notes. They talk to friends at other companies. They notice who has unrestricted access and who is rationing tokens like it is 2023.

You will not see it in your attrition dashboard. You will see it in a resignation letter. And the recruiter bill to replace that person will dwarf what you saved on their tokens for the entire year.

The pilot trap

Stop running eighteen-month pilots to evaluate something that costs less per month than a single recruiter fee.

Start with your top twenty engineers. Unrestricted frontier access. Sixty days. Measure the output delta. If it does not justify expanding, pull it back.

That is a decision you can make this week. Not next quarter. Not after the vendor evaluation. Not after the security review that has been sitting in someone's queue for four months.

Time cost Every month of delay is a month your competitors have unrestricted frontier engineers shipping while yours are managing token budgets.

Slide 08

To the Tool Makers: Your Margin Optimization Is Landing on My Keyboard as Friction

Product feedback
01

You gave us flow

You built something that let engineers sit down, start a session, and look up four hours later having shipped something real. Not a ticket. Not a story point. Something they are proud of. A lot of us had lost that.

02

Now you are taking it back

Token limits. Model pickers. Usage dashboards. Smart routing that is not smart enough. Every one of these is an interruption to the thing your product exists to create. You are selling flow and billing for friction.

03

Friction kills your product

Friction is the one thing your product cannot survive. The whole reason engineers pay you is flow. The moment you interrupt that, you are selling a car with a governor on the engine. And someone else will sell the same car without one.

You gave me back the joy of building software. Now stop taking it away forty-seven times a day with token limits and model pickers.

The engineer's actual experience

Slide 09

The 60-Day Challenge for Engineering Leaders

Action plan

What to do this week

  • Identify your top twenty engineers by output and influence.
  • Give them unrestricted frontier model access. No caps. No tiers. No usage dashboards.
  • Tell them to stop thinking about tokens and start building.
  • Set a sixty-day window. Measure the output delta against their previous quarter.

What to measure

  • Shipping velocity -- features delivered, not story points closed.
  • Engineer satisfaction and retention signals.
  • Quality of output -- are they building better systems or just more code?
  • Total cost versus the output delta. If it does not justify expanding, pull it back. It will.

Slide 10

Give Me the Best Model. Get Out of the Way.

Decision close
What engineers are actually asking for

Open the terminal. Tell the agent what we are building today. And build.

No model picker. No version number. No token anxiety. Just the agent at full strength, all day, every day. That is the product engineers want. That is the investment leaders should make. Everything else is noise.

The companies that figure this out first will have the best engineers, the fastest shipping velocity, and the strongest retention. The ones that do not will be explaining their tiered access model to a room of people who already have offers somewhere else.
