How Much Does It Cost to Develop an ML Solution in 2025?

The costs associated with developing ML solutions largely depend on the complexity of the project. For instance, creating a simple ML chatbot will generally be less expensive than developing a medium-complexity ML application, such as a virtual assistant, or a complex ML project, such as a driving assist system. Ultimately, the expenses for complex ML projects can escalate significantly. 

In a 2024 post, Elon Musk stated that “Tesla's cumulative investment in its self-driving program would be well over $10 billion this year”. This is how much some companies are spending on ML and AI-based systems. 

Simple ML Projects
Consider a scenario where you're developing an ML system using off-the-shelf tools. You would design and deploy models utilizing standard machine learning algorithms backed by organized, high-quality, and labeled datasets. This would be categorized as a simple ML development project. Such a project might range from $5,000 to $50,000 and would likely require between 1 to 3 ML developers. This project would likely take 1 to 8 weeks to complete. 

Medium-Complexity ML Software Development Projects
Imagine your ML project involves multiple capabilities, such as supervised learning, natural language processing, and computer vision. If the project requires developing medium-complexity ML models and relies solely on unlabelled data for training, it would fall into the medium-complexity category. Expect costs of somewhere between $50,000 and $250,000 and a timeframe of 1.5 to 6 months. This kind of project typically requires between 2 and 6 machine learning engineers.

Complex ML Software Development Projects
Complex ML projects will involve sophisticated models and advanced techniques like deep learning. They could require extensive data preparation, including unlabelled datasets such as visual recognition data from cameras that make up a driver-assist system. These projects often need specialized expertise and can cost significantly more than medium-complexity ones, requiring a team of seasoned ML engineers over an extended timeframe.

Defining Your ML Application Features

Your app must stand out to succeed in the competitive ML application market. If you created an ML application that mirrored all competitors' features, what incentive would users have to choose yours?

Developing a comprehensive feature list is essential for visualizing your ML app and its goals and, subsequently, allowing you to gauge your budgeting and hiring needs. Document all desired features and goals to create a clear product outline, which will guide you in hiring the right ML development team.

What Kind of ML Developers Do You Need?

If you’re updating an existing ML application that was built in R or need deep integration with R-based libraries, hiring an R developer is necessary. However, many newer developers specialize in Python, which is the preferred language for contemporary ML development due to its extensive libraries and community support.

Python vs. R: Pros and Cons

The primary difference is that Python allows developers to write streamlined code, eliminating the need for verbose syntaxes such as braces and semicolons. This means that a Python developer can focus on creating clean and maintainable code. This simplicity is especially beneficial for junior developers, as it reduces the chances of making errors that can lead to bugs. 

Note: I strongly advise against using junior ML developers in your project. Experience is key when it comes to ML development; don’t risk hiring junior ML developers. 

Python also includes several innovative features, such as dynamic typing and powerful libraries, which contribute to cleaner code with fewer issues. In contrast, languages like R can complicate memory management, making it a challenging task for developers. Python addresses this with its garbage collection system, which automatically manages memory by deallocating objects that are no longer in use.

Another crucial point to consider is support. While R is still supported by the community, the level of investment has decreased significantly in recent years. This is primarily due to the growing popularity of Python, leading to fewer libraries being developed for R. Over time, this waning interest may result in reduced support for R by its maintainers.

It is for this reason that I strongly recommend using Python. 

Backend Service Providers
Selecting a reliable backend service provider is essential for hosting your ML application, along with choosing the best backend developers who possess all the expertise to write the necessary code and set up your system.

Naturally, you'll want fast performance and reliability from your ML system and supporting web and mobile apps. Fortunately, many service providers meet these needs, though some stand out more than others. Here are my top picks for backend service providers.

Google Cloud Platform (GCP)
Google Cloud Platform offers an extensive range of products and services, including powerful tools like Google Compute Engine and TensorFlow for machine learning projects. Its robust AI and ML capabilities make GCP an excellent choice for those developing machine learning solutions.

Amazon Web Services (AWS)

6 Steps to Hiring ML Developers

Here are the 6 essential steps to hire a machine learning engineer:

Step 1: Define Project Requirements

Your machine learning project requirements encompass the specific functionalities, features, and goals that your project must meet for success. These requirements are crucial and should be established before entering the design and development phases.

While your project’s requirements may evolve during development, especially after launch, as you gather user feedback, the overall goals and core functionalities are likely to remain constant.

Take the time to mentally walk through the process of using your application, focusing on your specific objectives. If you are building a chatbot, then what level of engagement are you hoping for? Will your users expect short and concise answers or will they want long format and detailed answers, etc?  

Create a list of both functional and non-functional requirements, also considering aspects like scalability, performance, and security.

Once your project requirements are clear, you’ll have a better understanding of the type of ML engineers and backend developers you will need.

What Type of Developers Will I Need for a Machine Learning Project?
The intricacy of your project and the tech stack you choose will determine how many and what kind of developers and data engineers you will need.

For a typical machine learning project, you would most likely need one or more mid-level or senior Python engineers with knowledge of machine learning frameworks such as TensorFlow or PyTorch. Multiple developers, a data scientist, and possibly a UI/UX designer may be required for mid- or enterprise-level projects.

You will also need experts in those fields if your project calls for specialist technologies like data engineering, natural language processing, or deep learning.

If you're unsure of your needs, consider speaking with one or more machine learning development specialists. Making contact with ML-focused software development firms will likely yield very insightful information.

Step 2: Software Development Company or Freelancer Platform?

Create a job description template when you've decided on the specifics of your project and post it to freelancing websites or job boards. This template will also make contacting software development companies easier. Let’s now look at how these platforms differ.

If you do not want to hire a machine learning engineer full-time, you can hire from a software development business or a freelancer platform.

Hire Machine Learning Developers from a Software Development Company
The safest option for hiring developers is to work with a dedicated software development company that provides full-time staff on an outsourced (temporary) basis to client companies.

Advantages of hiring developers from a software development company include:

• Access to a wide range of expert developers.
• Developers who are fully vetted and work for the company full-time.
• Experience with similar projects enhances the likelihood of success.
• Assignment of an account manager to facilitate communication and project management.
• Inclusion of a quality assurance (QA) professional to oversee the project before launch.
• Access to project management tools and processes.
• Contracts that safeguard your intellectual property (IP) rights.
• Risk-free trials allow you to evaluate a developer’s fit without a long-term commitment.

Hire Machine Learning Developers from a Freelancer Platform
Freelancer platforms may be a viable option for small-scale projects on a tight budget.

However, the downsides include:

• Freelancers often juggle multiple projects, leading to part-time commitments.
• A time-consuming vetting process to check past work.
• The risk of freelancers abandoning your project for more lucrative opportunities.
• Potential issues with intellectual property security.
• Lack of project management tools or oversight.

I recommend being cautious with freelancers, as many companies encounter significant challenges when their hired freelancers lack the necessary skills or leave unexpectedly. Opting for a professional software development company can save you from these headaches.

Step 3: Interview Your Machine Learning Candidates

You should conduct three interviews: a primary interview, a skills interview, and a final interview.

• What communication platforms do they prefer (e.g., Slack)?
• Do they have a GitHub repository, or can they access yours?

Ensure remote developer candidates can overlap with your working hours by at least four hours for effective communication during planning and problem-solving.

Skills Interview:
This interview assesses the technical skills of your machine learning candidates. If you're not experienced in ML development, consider involving a professional who can help evaluate candidates' technical answers.

You might also consider assigning a coding problem that is relevant to your project. This will allow you to gauge their coding style and familiarity with necessary frameworks.

Final Interview:
By this stage, you should have narrowed it down to three or four candidates. This will be the most in-depth interview, focusing on their ability to meet your project’s specific needs.

For example, ask how they would implement a machine-learning model for a particular feature. Gauge their understanding of the tools and technologies they would employ and discuss potential challenges and solutions.

Step 4: Carefully Review Their Past Projects

It’s critical to thoroughly check references and past projects. Encourage candidates to demonstrate their previous work during the final interview to validate their skills. Look for relevant projects that showcase their expertise in machine learning and their problem-solving abilities.

Step 5: Onboard Your Machine Learning Developer

After you've decided on a candidate, give it some thought to be sure you made the best decision.

Before providing project details, have them sign a non-disclosure agreement (NDA) to start the onboarding process. Give them the equipment they need and give them a tour of your development team. Clearly define your expectations and development approach, as well as communication channels.

Give them all the tools they require, such as project schedules, paperwork, and any pertinent training materials, so they can begin contributing successfully right away.

Step 6: Set Expectations and Goals

Setting clear objectives and goals for the machine learning developer is crucial after onboarding. Specify their roles within the project and include deadlines and deliverables. Plan frequent check-ins to keep an eye on things, handle obstacles, and make sure the project's goals are being met.

By following these procedures, you should be able to effectively incorporate your new machine learning developer into your project, maximizing their contributions and guaranteeing the accomplishment of your machine learning project.

That is all. Your ML developer can immediately begin working on your project.
