Why Hiring In-House AI Developers Is a Bad Idea, Even If You Are an IT Company

AI development is still often discussed using an old staffing mindset.

It sounds like this:

• hire AI developers in-house;
• give them access to the best models;
• assign a manager;
• build a process;
• and get predictable, fast, cheap delivery.

In practice, more and more companies are seeing the opposite.

They get:

• expensive, poorly controllable variable spend on models;
• weak transparency into how that resource is consumed;
• a structural incentive conflict between the employer and the executor;
• a team that has very little reason to be truly cost-efficient.

The main thesis of this article is blunt, but increasingly practical:

in the era of AI development, an in-house team stops being the default economic model. In many cases, even for an IT company, it becomes a less rational model than a strong contractor paid for outcome and deadline.

Important nuance: this is not an argument against internal tech ownership.

Most companies still need internally:

• an architecture owner;
• a product decision-maker;
• operations and maintenance;
• small ongoing changes;
• an internal knowledge boundary for the system.

But the heavy part of AI delivery, especially new product development, is increasingly not profitable to keep in-house.

Not because people are bad. But because the economics of the tool and the incentives of the executor no longer align.

Why AI Development Breaks The Old Hiring Model

In traditional software development, companies roughly understood what they were paying for.

Yes, there was inefficiency, but the picture was familiar:

• juniors ship less;
• mid-level engineers ship more;
• seniors ship even more and better;
• supported by QA;
• business analysts;
• project managers;
• team leads;
• architects;
• product owners.

It was heavy, expensive, and slow. But it was at least intuitively understood.

Today, that structure is collapsing fast.

In many strong AI projects, the real delivery configuration already looks like this:

• an architect or a very strong engineer;
• AI as a working accelerator;
• optionally a business analyst;
• testing done at acceptance time or on the customer side.

That is it.

What used to take a year can, in some cases, be done in a couple of months. What used to take a week can sometimes be done in hours.

This is where many companies make a dangerous assumption:

if it is that much faster, we should just hire more AI developers in-house and accelerate even more.

But they miss the key point.

AI is not only acceleration. AI is an expensive and hard-to-control production resource.

AI Is Not a Free Assistant. It Is Expensive Fuel.

When an engineer works in Professional AI Coding mode, they continuously burn paid compute.

This is not an abstract “chat subscription”. It is variable spend.

In practice, the pattern often looks like this:

• a simple work item can cost $1-2 in model spend;
• a medium item can cost noticeably more;
• a hard item can easily reach $20-30 just for the model interaction, context handling, retries, refactoring, and verification loops.

If a strong AI developer runs 100-200 micro-cycles per day, the monthly AI budget for a single person can easily land in the $3,000-5,000 range, and sometimes above.

This is the honest reality:

in AI development you are not only paying for a person. You are paying for a person plus their personal channel of consuming expensive compute.

That is why the old formula “salary + laptop + manager” no longer describes the real production economics.

The Core In-House Problem: The Executor Is Not Incentivized To Optimize Your AI Budget

This is the uncomfortable management truth.

An in-house AI developer is almost never strongly incentivized to optimize your AI budget.

Not because they are a bad person. But because the incentives are structurally different.

For them:

• every extra model iteration is not paid from their pocket;
• extra retries do not reduce their personal income;
• model overspend does not automatically make them less valuable to the employer;
• speed is often rewarded more than frugality.

The employer wants:

• fast;
• high quality;
• and cost-efficient.

But the executor in the in-house model naturally drifts toward a different local optimum:

• fast for themselves;
• convenient for themselves;
• without personal pain from compute overspend.

That is a structural conflict.

Three Scenarios In-House AI Teams Usually Converge To

1. A decent employee simply burns your budget

This is not necessarily abuse. Most often it is normal workflow inertia.

People:

• try too many approaches;
• run long contexts unnecessarily;
• rewrite the same part multiple times;
• keep too many parallel AI sessions open;
• ask the model to do things that could be done cheaper and shorter.

They can be fully honest. But their internal incentives are rarely as strict as those of someone who pays tokens from their own budget.

2. Your AI resource starts funding someone else’s tasks

This is a more unpleasant scenario.

When a developer has access to a costly AI setup and there is no near-perfect transparency, you quickly enter a gray zone:

• side projects;
• “learning experiments”;
• helping friends;
• parallel freelance work;
• training on your resource;
• model spend outside your direct tasks.

Yes, you can say: “we will ban it.”

But bans and real transparency are not the same thing.

3. You build a heavy control system that still does not make it transparent

This is the classic corporate reaction.

When spend leaks and nobody can explain it, the company builds a control layer:

• logs;
• limits;
• policies;
• approvals;
• metrics;
• internal audits.

The problem is that AI skill does not reduce well to simple metrics.

It is not enough to know:

• number of requests;
• total spend;
• lines of code generated;
• hours online.

You need to understand subtler things:

• could the task be solved cheaper;
• was the right context strategy used;
• does this engineer truly know how to work with models professionally;
• are they masking weak architecture skills behind expensive model activity.

This is not tracked linearly.

So the company often arrives at an absurd configuration:

for every person with AI, you effectively add another person with AI to monitor their efficiency.

Instead of optimizing, you just add management and cost layers on top of an already expensive production model.

Why Old Productivity Metrics No Longer Work

The market used to think in crude, linear terms:

• junior ships 150 lines/day;
• mid-level ships 350;
• senior ships 550;
• and you add QA, analysts, managers, etc.

This model was always rough, but now it is close to useless.

Because in AI development, value is no longer in line counts or headcount.

Value is now in:

• who can frame the task correctly;
• who can keep the architecture boundary;
• who can verify results quickly;
• who can avoid drowning in AI iteration cost;
• who can ship a system in weeks, not quarters.

A single strong architect with AI can now replace a large part of the old chain.

That is why hiring “five more developers” does not mean five times more output. But it almost always means a larger budget.

Why Hourly Billing And Team-Based Staffing Start To Break Too

If AI truly accelerates work by 5-20x, and in good cases lowers cost by 5-10x, a very uncomfortable question appears:

why should the customer pay for many people and many hours if the result can now be delivered much faster?

And then a second, even more uncomfortable question:

why would an in-house executor voluntarily deliver that fast if their incentives are not tied to the economic outcome?

No sane person inside a salaried structure will voluntarily:

• sharply reduce their own workload;
• aggressively optimize the employer’s expensive compute;
• deliver in hours what used to be paid for in weeks;
• erase the need for half the old roles faster than the organization can absorb.

This is not morality. This is incentive design.

The Analogy Business Already Understood In Construction And Industrial Design

In construction and industrial design, this has been understood for a long time.

Even large corporations often do not keep a full production pipeline in-house for everything.

They keep internally:

• operations;
• small maintenance work;
• technical supervision;
• contractor management.

And they outsource large build and design projects.

Why?

Because contractors are paid for:

• outcome;
• deadline;
• compliance with conditions;
• and their ability to optimize their own internal costs.

The customer does not have to pay hourly for someone else’s inefficiency when the market supports outcome-based delivery.

AI development is moving in a similar direction.

Why Contractors Are Often More Rational In AI Delivery

When you work with a strong external executor, the incentive model changes.

A contractor knows:

• the more efficiently they spend AI compute, the higher their margin;
• the better their process, the faster they ship;
• the better their architecture and AI workflow skills, the lower their internal cost;
• overspending models hurts them, not you.

That is why contractors are far more motivated to:

• optimize model usage;
• avoid unnecessary contexts;
• standardize workflows;
• reuse proven engineering patterns;
• reduce expensive iteration loops;
• ship faster.

This is the economic shift.

Contractors used to look “expensive” while in-house looked “predictable”. Now, contractors are often cheaper in total cost of outcome, because their incentives align with optimizing expensive AI spend.

What The Rational Model Looks Like Now

More and more companies will converge to this configuration:

• internally keep product ownership and architectural acceptance;
• keep a small internal tech boundary if necessary;
• keep operations and acceptance close to the business;
• outsource intensive AI delivery to strong contractors or a lab.

This is especially logical when the business does not need “a department of presence”, but:

• a product;
• a deadline;
• a clear scope of outcome;
• a clear budget;
• and accountability for cost-efficiency on the executor side.

That is why in AI delivery, the rational unit of purchase becomes not person-hours or team size, but outcome delivered by a deadline.

Objection: “But We Are an IT Company”

This is the most interesting objection.

Many IT companies still assume they must keep all AI capabilities in-house.

Reality is more nuanced.

Being an IT company does not automatically mean it is rational to:

• keep a large in-house AI staff;
• pay their variable AI spend;
• build an expensive internal control system;
• absorb the inefficiency of their working loop.

Even for IT companies, a rational model often looks like:

• keep architectural control internally;
• keep acceptance and product knowledge internally;
• keep critical operational functions internally;
• outsource high-speed build and major delivery waves to those who operate as a production service.

The question is no longer about the label of the company. The question is where incentives, speed, and accountability for expensive AI compute align better.

Where In-House Still Makes Sense

To avoid a new extreme: in-house does not disappear completely.

It still makes sense for:

• operations;
• support for existing systems;
• small changes;
• internal acceptance and technical review;
• security;
• domain and product knowledge on the customer side.

But that does not change the main point:

keeping a large volume of AI production in-house is increasingly less rational than buying an external outcome from those who are incentivized to optimize their own AI spend.

Practical Conclusion

AI can make development:

• 5-20x faster;
• 5-10x cheaper;
• shorter in number of roles;
• higher in output density per person.

But this only works under two conditions:

• the person truly knows how to work with AI professionally;
• and they are personally incentivized to optimize expensive compute.

The second condition almost never exists in the in-house model.

So the practical conclusion for business is:

in the era of expensive AI, it matters less how many people you hire internally. It matters more who is accountable for outcome, deadline, and model spend.

Maxim Zhadobin, founder of THINKING•OS AI Laboratory and Lead AI Architect of Tao Platform, treats AI development not as “expanding the programming staff”, but as a change in the entire production economics of digital products.

THINKING•OS develops production AI as an engineering discipline where the focus is not on hours of presence, but on controlled outcomes, architectural maturity, and the true cost of execution.

That is why for many companies, including IT companies, the next rational step is not growing in-house AI teams, but moving toward a model where the contractor is accountable for the outcome and is naturally incentivized to optimize their own AI budget.
