1. The Rise of Industry-Specific Private LLMs

While adoption rates of public or generic large language models, such as Open AI’s ChatGPT, Google’s Gemini, and Anthropic’s Claude, are impressive, these models still pose challenges for some. Data security and privacy concerns, the costs of implementation, and even accuracy, are cited as drawbacks that make certain industries and businesses wary of adoption. This has led to the concept of industry or domain-specific models that are highly specialized and tailored to specific industry verticals is gaining attention. 

According to a McKinsey study, companies investing in domain-specific AI models are projected to see 3-5x higher performance improvements compared to those using generalized models. We expect that during 2025, this trend towards private or hyper-specialized LLMs will accelerate as companies look for increased performance while lowering the risks.

Financial services, healthcare, and regulated industries will lead this trend by developing or leveraging proprietary models trained on domain-specific data. These models will excel at understanding nuanced industry terminology, compliance requirements, and context enabling them  to align with specific use cases, workflows, and business priorities. They will be instrumental in delivering increased accuracy while reducing exposure to third-party risks, making them especially relevant to these industries.

2. Voice AI Reimagined: Generative Intelligence Meets Conversational Interfaces

Voice is hot again! Research from Opus Research indicates that by 2026, 65% of enterprise voice interactions will incorporate generative AI capabilities, up from less than 15% in 2024.

Voice has always been a critical communication channel but the combination of AI and voice in the form of LLMs, speech recognition, and voice bots have revived the business value of voice AI. This is only set to further increase the popularity of voice as a channel. Generative AI is dramatically enhancing voice assistants, moving beyond scripted responses to truly contextual, nuanced interactions. These next-generation voice interfaces leverage advanced language understanding to provide more empathetic, context-aware communication across customer service, healthcare, and enterprise support channels. 

Current voice solutions continue to use Speech-to-Text and Text-to-Speech to interact with people. The next wave of solutions will be directly voice-to-voice, with conversations flowing naturally and close to zero lag. This major leap forward in User Experience will transform voice bots but come with their own unique technical challenges.

To date, voice has been pretty much an added layer, tacked on to a bot. The next generation of voice bots will use more advanced voice recognition, versus converting voice to text and text to voice. Open AI, for example, is experimenting with Whisper, an automatic speech recognition (ASR) system trained on multilingual and multitask supervised data collected from the web. This has the potential to significantly enhance voice bots by improving their ability to understand and process spoken language. 

Real-time biometrics and sentiment analysis from audio will further enhance AI. Capabilities such as inferring user sentiment during and after interactions, or scoring satisfaction levels based on tone and biometrics, will become increasingly common.

The use of real-time voice modification software is expected to rise significantly, particularly in outsourcing scenarios, as organizations strive to present neutral voices and mask geographic origins. This technology processes incoming audio to standardize regional variations, enhancing agents’ ability to understand intent clearly and accurately. By removing linguistic barriers, voice modification ensures smoother communication while enabling the detection of underlying emotions and sentiment in real-time. These insights can be analyzed to discover patterns, optimize voice interactions, and provide agents with actionable data.

3. AI Copilots Expand Beyond Customer Service, as they are Tailored to Diverse Business Areas.

Rather than replacing human workers, AI assistants will emerge as powerful collaborative tools that augment human capabilities. We’ll see a shift from standalone AI tools to deeply integrated AI Copilots that work alongside professionals, offering real-time insights, automating routine tasks, and providing intelligent recommendations.

The adoption of bespoke Copilot applications will continue to expand beyond customer service, as businesses increasingly recognize the potential of generative AI to automate and enhance workflows across diverse departments. The capabilities of AI Copilots, such as their ability to process large volumes of data and provide real-time insights, make them invaluable for other use cases and functions across the business. 

As organizations look to optimize operations, these tailored Copilots are expected to address gaps in efficiency, accuracy, and scalability in areas like supply chain management, product development, and data analytics. Their adoption will also be fueled by increasing investments in enterprise AI infrastructure and the growing availability of tools that allow for department-specific AI fine-tuning. This trend marks a shift from generic, one-size-fits-all solutions to highly specialized AI applications that align with unique business goals and workflows.

4. The Rise of Autonomous AI Agents (Copilots Become the Pilot)

Taking the rise of Copilots one step further is the increasing focus on Agentic AI, i.e. Autonomous AI Agents. While this is not for those in the experimentation phase of their Gen AI implementations, this concept continues to be a hot topic and we expect it to continue to create a buzz. For instance, a DeepMind study predicts autonomous AI agents could improve strategic decision-making efficiency by up to 65% in enterprise environments by 2026.

The evolution of agentic AI is driving a shift from task-focused automation to systems capable of strategic problem-solving and autonomous decision-making. Autonomous AI agents, powered by advanced generative AI and large language models (LLMs), are moving beyond assisting human workers (i.e. Copilots) to take the lead in managing complex workflows, with no human intervention. These systems will autonomously interact with other tools and systems to break down business challenges, generate strategies, and adapt dynamically. An example is Anthropic’s recent release of MCP demonstrating a major leap forward in agentic AI. It is a new standard for connecting AI assistants to the systems where data lives, including content repositories, business tools, and development environments.

The foundation for this shift lies in advancements in AI reasoning capabilities, such as the ability to process unstructured data, identify patterns, and synthesize insights across vast datasets. The rise of autonomous AI agents reflects a broader trend in AI adoption, where the focus is shifting from augmenting human capabilities to creating systems that can function as independent, intelligent entities. For most business use cases this will be a progression from “human-in-the-loop” AI systems to trusting the AI systems to fully manage specific workflows, without introducing risk factors that may harm the business.

5. The Convergence of Multimodal AI: Beyond Text and Voice

We expect to see AI assistants rapidly evolve beyond single-modality interactions to seamlessly integrate multiple input and output modalities, creating more intuitive and comprehensive interaction experiences. 

In the context of LLMs and Generative AI, multimodal capabilities mean that AI systems can process and respond to not just text and voice but also images, videos, gestures, and even visual interfaces. For example, an AI assistant could analyze a customer’s spoken query, reference a related document uploaded during the conversation, and present a visual explanation, all in real-time. Fluid switching between modalities enhances user interactions and experiences, breaking down communication barriers across different platforms and user preferences. 

The implications of multimodal AI are significant, particularly for businesses that are interaction-intensive and/or require complex information sharing. Retailers could deploy multimodal AI to offer more immersive customer experiences, such as visual product recommendations based on user-uploaded photos. In healthcare, multimodal systems could analyze text-based patient records, diagnostic images, and doctor-patient conversations to provide comprehensive insights. 

Research from Stanford University’s Human-Centered Artificial Intelligence (HAI) Institute predicts that these capabilities could boost user engagement by up to 55% in enterprise and consumer applications by the end of 2026. As multimodal AI becomes more prevalent, it promises to redefine how businesses interact with their customers and how teams collaborate and innovate internally.

6. Synthetic Data Will Redefine AI Development and Privacy Protection

Data is the essential fuel to build and tune LLMs. With growing demand for more specialized or private LLMs, we expect to see organizations adopt synthetic data generation to train these models. Synthetic data, created programmatically to mimic real-world data, provides an excellent solution for industries that opt for this private LLM route as it allows for expanded use of AI in privacy-sensitive situations while accelerating AI development.

This approach is particularly valuable in industries with stringent privacy regulations, allowing organizations to maintain compliance while still leveraging data-intensive AI solutions. In the finance industry, for example, synthetic data can be generated from transcriptions of customer service interactions to train LLMs for applications like fraud detection, personalized financial advice, or automated compliance checks. 

Financial institutions often handle sensitive customer data protected by regulations, making it challenging to use real data for model development. By using synthetic data, these institutions can train LLMs on realistic transaction patterns, conversation flows, and regulatory scenarios without exposing any personally identifiable information (PII). This accelerates AI development, improves model robustness, and ensures that AI-driven solutions remain compliant. 

Synthetic data serves as a crucial enabler, bridging the gap between privacy protection and innovation in data-driven AI systems.

7. The End of One-Size-Fits-All: AI’s Role in Creating Dynamic Customer Experiences

Generative AI is moving beyond the traditional one-size-fits-all approach, enabling systems to create truly personalized interactions by adapting dynamically to a user’s individual needs. Unlike rigid, rule-based designs, AI-driven interfaces can tailor the user experience based on real-time behavior and context.

The transformation of customer experiences extends to the interfaces and back-end processes that drive them. Adaptive user interfaces (UIs), powered by LLMs, will adjust in real-time based on user behavior, preferences, and context. Previously hardcoded relationships between UI steps will become more fluid, leveraging LLMs to produce more usable, personalized, and accessible experiences. 

For example, a shopping app might restructure its interface for a user who frequently shops for a specific category, surfacing relevant options while minimizing irrelevant steps. On the backend, AI agents will guide customers through the customer journey autonomously, handling multi-step processes dynamically. Much like Gamebooks or choose your own adventure books, the next step is determined dynamically based on user input and preferences. 

Conclusion
