Build a Custom AI Model of Your Work: The New AI Trend

Businesses are increasingly building custom AI models on top of open-weight foundations to avoid dependence on major AI providers like OpenAI and Anthropic. This strategy offers greater control over costs, data, and access, much like controlling internet infrastructure in the early days. The practical approach involves taking an existing open-weight model and fine-tuning it with specific work examples to excel at a single, repeated task.

• Startups and researchers are building custom AI models on open-weight foundations instead of relying solely on large AI companies.
• This approach offers more control over costs, prevents risks of API changes or access restrictions, and ensures ownership of business intelligence.
• Building a custom AI model doesn’t mean creating a new ChatGPT; it means fine-tuning an existing open-weight model for specific tasks.
• Examples of custom AI tasks include drafting newsletters from research, generating company-approved responses to customer emails, or creating weekly reports from meeting notes.
• Before training a custom model, explore simpler methods to solve the task.
