What buyers should weigh
Organizations evaluating AI customization tools should consider whether their internal teams lack the technical skills for post-training adjustments. The availability of tools from vendors like Trajectory could reduce reliance on external consultants for model tuning. Buyers must verify if these tools support the specific foundational models, such as those from OpenAI or Anthropic, that their organization already uses. Cost structures for these services remain unclear in the current reporting.
