Major criteria for selecting top custom AI development companies

While looking for an AI software development company to provide consulting services or craft tailored solutions for your organization, you should pay attention to the following factors.   

Innovation and technology 

To attract your attention, an artificial intelligence development company should leverage an advanced tech stack in its projects. The list of libraries, frameworks, programming languages, and methodologies in which the vendors’ experts are competent should include the most disruptive technologies.  

Expertise and experience 

You should consider the time of the company’s presence in the IT market in general and its experience in working with AI technologies in particular. Besides, the qualifications of the staff matter greatly, especially when proven with appropriate certificates. 

Industry impact and case studies 

If the company specializes in, say, tourism solutions while you work in the fintech field, it won’t be the best choice for your industry-specific project. That is why you should regard this aspect and study the vendor’s portfolio, looking for similar projects in closely related fields. 

Client testimonials and reviews 

These are the yardsticks for measuring customer satisfaction obtained from the cooperation process and results. You should peruse customer feedback not only on the vendors’ site but across rating platforms (such as Clutch or GoodFirms) to get a complete and objective picture. 

Sifting through dozens, if not hundreds, of options and comparing AI software development companies along multiple parameters is a time- and effort-consuming endeavor. We can simplify the choosing routine for you by offering the roster of the 10 best AI development companies in the market.

Trends in AI development: Glimpses of the future

As a forward-looking IT vendor, DICEUS tries to stay ahead of the technological curve, keeping track of the emerging trends in the niche.  

Democratization of AI 

At its arrival, any new know-how is a big-ticket item, requiring highly specialized expertise for handling. Over time, it undergoes democratization: it becomes more affordable, with many users learning its ropes. This progress pattern is characteristic of artificial intelligence as well, and the advent of ChatGPT was a visible marker of such a shift.  

Today, any person without technical training can utilize it to generate synthetic texts and images free of charge, while for organizations, the low subscription fee is a good bargain. Evidently, other AI-powered technologies are likely to follow suit one of these days, becoming available for non-tech personnel of small businesses and startups on short commons, who will leverage their enormous potential in multiple professional use cases.  

Multimodal AI 

AI solutions will move from their current ability to process and generate only one kind of data to multimodal principles when models fueling them allow AI tools to handle texts, video, audio, and images within one input and produce content containing all of them in the output. iPhones can already perform object recognition on photos by analyzing images, metadata, and search data. Other AI systems are likely to embrace this function pretty soon.  

Agentic AI 

AI tools are becoming more independent in doing their jobs. They will gradually turn into totally autonomous AI agents that can perceive the environment, register changes in it in real-time, make conclusions, plan their actions, execute them, and analyze the results, constantly learning from each interaction thanks to feedback loops. Moreover, being honed to solve specific assignments, they will be able to cooperate in dealing with more complex tasks, radically streamlining and facilitating network diagnostics, fraud detection, risk evaluation, and customer service in different industries.  

AI-assisted software development 

Large chunks of software code are repetitive but necessary elements of the program, so developers spend a lot of time reproducing them over and over again. The SDLC proceeds at least 25% faster and error-free when code generation tools like Copilot by Github come into play. 

The most disruptive platforms used as software development assistants can not only understand syntax, consider context, and anticipate code lines, completing them. They can also be employed for code review and optimization, bug detection and resolution, quality assurance, etc., and over time, the scope of AI functionalities in this area will only expand. Gartner predicts that next year, close to a third of new apps will have AI-generated UI, whereas in 2027, 15% of such products globally will be produced by AI without human participation. 

Ethical AI development and compliance 

As the role of AI across multiple spheres enhances, people take thought for its ethical usage, which presupposes delineating accountability zones between AI developers and users, ensuring transparent and unbiased operation of AI models, and guaranteeing privacy and security of data employed for model training.  

Seeing that many people still feel a distrust towards artificial intelligence (in the USA, this number amounts to 70%), governments have become concerned about AI ethics, too, issuing stringent regulations. So far, such laws (GDPR, HIPAA, CCPA, and others) are mostly related to data security and cover any digital products; however, the legal framework is expanding to include AI initiatives specifically.  

In May 2024, the EU adopted the Artificial Intelligence Act that establishes a dedicated AI Office at the European Commission that will issue decrees concerning limitations and checks of high-risk AI systems. The US federal legislation lags behind in this domain, so state governments have stepped into the breach. And the harbinger of future changes is the Colorado AI Act, passed by the state in the same May. We will definitely see other similar laws implemented by local and national governments soon.  

Conclusion

With artificial intelligence swiftly becoming part and parcel of our lives, many businesses face the necessity of implementing AI-powered products in their workflows. To choose a qualified and reliable vendor for accomplishing AI initiatives, enterprises should consider a candidate’s experience and expertise in the niche, the technologies it leverages, the case studies showcasing the completed projects, customer reviews, and the vendor’s commitment to follow the latest trends in the domain.
