Possible disadvantages of Haystack NLP Framework

  • Resource Intensive
    Running and fine-tuning models can be resource-intensive, requiring significant computational power and memory, which may not be suitable for all users or small projects.
  • Complexity
    Though modular, the framework can be quite complex due to the many interchangeable components and configurations. This may overwhelm beginners or those without a background in NLP.
  • Deployment Challenges
    Deploying Haystack-based applications may require additional work and expertise in cloud services and containerization, which can be a barrier for some developers.
  • Continuous Maintenance
    As an open-source project, keeping up-to-date with the latest changes and updates can require continuous maintenance and monitoring.
  • Limited Real-World Examples
    While the documentation is extensive, there are relatively fewer real-world example projects available compared to some other NLP frameworks, which can make it harder to understand how to apply it to specific use cases.
  • Learning Curve
    Despite its extensive documentation, the learning curve can still be steep for those unfamiliar with NLP concepts and frameworks. Initial setup and configuration can be time-consuming.

  • Building a self-creating website with Supabase and AI
    Creating AI speech isn't that difficult thing to do, however it is a bit challenging to find an API that doesn't cost you your kidneys. Luckily I ran into Unreal Speech which has some pretty generous free monthly tier. However it will not suffice for us to run the site generations for a over month, so I'll need to do some tricks here and there to keep things running (or just open up my wallet). - Source: dev.to / about 1 year ago
