1. Generative AI strategy & use case identification services

A sound strategy is essential for any business planning to integrate generative AI into its business processes. This can be challenging because it requires a deep understanding of both AI technologies and the specific business context, including:

  • Operational needs
  • The skills of the existing workforce
  • Ethical considerations
  • The potential impacts and risks of AI deployment.

Strategy services help develop this roadmap, and top players include:

BCG supports businesses in using AI by advising on how to integrate AI into their processes and decision-making. The company helps organizations identify relevant AI applications, implement solutions, and scale technologies to improve operational efficiency and performance.

2. Generative AI training data collection services

Generative AI models require large amounts of data to be trained. Software developers can work with data collection services to fulfill their data needs without facing the data collection challenges and solutions. These services focus on data collection, preprocessing, annotation, and other services involved in preparing a training dataset for generative AI models.

Popular names in the market are:

Clickworker

Clickworker is a crowdsourcing platform that offers data collection and annotation services for training generative AI models and data for LLMs, including text, image, and video data generated by humans. This service provider is good for large-scale projects due to its large network of contributors.

Appen

Appen offers data annotation and model training for generative AI, supporting tasks like natural language processing, image generation, and speech synthesis. Appen is good for midsized projects due to its mid-sized network of participants.

Amazon Mechanical Turk

Amazon Mechanical Turk offers a marketplace for data labeling and verification services for generative AI models, including text generation, image tagging, and content moderation. MTurk is suitable for small-scale projects due to its small network of participants.

3. Generative AI hardware solution providers

During training, generative AI systems require high-performance computing capabilities to efficiently process and learn from massive amounts of data, necessitating specialized hardware such as GPUs or TPUs.

Once the model is trained, similar hardware is used for inference (e.g., to run the pre-trained models).

Working with a third-party service provider can help you achieve such computational capabilities. These services provide specialized hardware to help train and run generative AI models efficiently.

There are a few different types of service providers which allow companies to trade-off between capital expenses and operating expenses:

  • AI hardware companies like NVIDIA and AMD provide powerful GPUs that are crucial for training generative AI models due to their parallel processing capabilities. These companies mainly serve data centers, enterprise clients, and consumers in industries such as computing, gaming, and professional graphics.
  • Cloud GPU providers: You don’t need to own AI hardware to use it. Hyperscalers like AWS, Google and other cloud providers provides GPUs on their clouds. Some providers like Google provide their own hardware. For example, Google’s Tensor Processing Units are only available on GCP and are designed specifically for neural network machine learning.
  • Serverless GPU providers: Serverless GPUs facilitate GPU scaling and management.
  • Inference APIs: Instead of managing hardware, users can use APIs to receive answers from large language models or other AI systems.

4. Generative AI foundation model providers

AI foundation models are the backbone of any generative AI system. These are complex models trained on extensive datasets and can generate outputs in a range of tasks without task-specific training data. 

Two notable services in this area include:

OpenAI

OpenAI is renowned for its GPT series, including GPT-3, GPT-4, and its latest o1 reasoning models. These models are powerful language processors capable of generating human-like content, answering questions, and performing various language and programming tasks. They are widely used in applications like content creation, virtual assistants, programming, and more.

Google

Google has developed several generative AI models such as BERT, T5, and LaMDA (Language Model for Dialogue Applications). These models are used to enhance search algorithms, power conversational agents, and assist in tasks like translation and summarization.

5. Generative AI training and development services

Training a generative AI model is a challenging process that requires specialized skills because it involves: 

  • Understanding complex algorithms
  • Optimizing neural network architectures
  • Handling large datasets
  • Fine-tuning models to generate high-quality outputs while avoiding pitfalls such as overfitting or mode collapse.

Third-party service providers can help streamline the whole development process. 

Such services include:

H2O.ai

H2O.ai offers a machine learning platform that helps build AI models to improve business operations, including generative AI, without necessarily having an extensive background in AI.

AWS SageMaker

Amazon’s SageMaker is a fully managed service that provides developers and data scientists with the ability to build, train, and deploy machine learning models, including generative AI models.

6. Reinforcement Learning with Human Feedback (RLHF) service providers

RLHF is an approach to machine learning that combines traditional reinforcement learning methods with human feedback. Usually, companies with a large network of contributors, like crowdsourcing platform/service providers, offer RLHF services. The services train AI models using a blend of algorithmic learning and human feedback, which refines model behavior and ensures alignment with human values.

Some of the service providers in this category include:

Clickworker

Clickworker offers RLHF services through its crowdsourcing platform and a large network of contributors.
