    IBM
    Where IBM watsonx.ai is well suited, based on our team experience: Num#1: Internal knowledge assistants for large companies. Like GAIA already described, is a good example. IBM watsonx.ai works very well as the base for a RAG solution. Num#2: Projects where data privacy is important, because we know that with IBM watsonx.ai client data are not used to train the models and everything stays inside IBM Cloud. Num#3: Solutions that need flexibility on models or projects designed to last a long time, because models change during time, so it's important to use a service that permit a smooth change of model Less appropriate: Num#1: Large and complex agent-based systems. Because IBM watsonx.ai gives the models and the APIs, but you have to build everything else yourself. So agent logic, orchestration, tool calls, etc. For GAIA this was manageable, and building our own multi-agent layer gave us full control, it was ok. But for larger projects, with many agents, complex workflows and integrations with many business systems, this means a lot of custom development and maintenance. So better to use other services (like orchestrate)

    For smaller organizations that run lean and would like to get to deploy a solution quickly. This is a solution that is easy and quick to develop. It has a good amount of customization. However, for advanced customization this might not be a good solution. I suggest experimenting with OpenAI API and then if the experimentation is successful then it is a good idea to optimize and try other LLM models.

    • The developer experience is top notch. Their SDKs are super easy to use
    • Organization and project billing separation. You know where everything was consumed.
    • Playground. The playground is super useful to prototype without writing a single line of code

    Cons
    IBM
    • Should allow flexibility to handle unstructured data in a more robust data labeling and annotation tools
    • real-time collaboration features are minimal which causes development less efficient.
    • There is no clarity around automated model monitoring and retraining features
    • Lack of pre-built industry specific models requires more customization effort for certain use cases

    I still don't have enough experience, but i have seen a lot of demos and i have made some real world scenarios and so far so long every thing looks fine. I was at IBM Think 2025 and IBM TechXchange 2025 and the labs were really usefull and simple to understand.

    Usability
    IBM
    I needed some time to understand the different parts of the web UI. It was slightly overwhelming in the beginning. However, after some time, it made sense, and I like the UI now. In terms of functionality, there are many useful features that make your life easy, like jumping to a section and giving me a deployment space to deploy my models easily.

    Easy to setup, develop and deploy. The payload for the API is simple and has all the inputs required for simple projects. There are a good number of options of LLM models to optimize for speed, cost or quality of the answers. A larger token input might improve the overall usability.

    I think IBM watsonx.ai is more IBM products focused so it helps find information for IBM related products better. For example I would with IBM assembler, but this language doesn't have too much documentation in GitHub Copilot, so the results I get from it aren't as helpful

    Anthropic is only the best for coding and its really really expensive. So, if you're not making a coding app, I would stay away from it. On the other hand, Gemini models are dirt cheap but come with a bit of performance limitations, so i would use it for big volume non sofisticated use cases. The OpenAI API platform excels at providing best in class performance models, at not outrageous anthropic-like pricing.

    IBM
    • For one of the usecase we were able to save 1.3 million dollar by creating the COB project in 2 months by leveraging the whole ecosystem and savibg of approximately 2800 hrs per annum
    • For the icd usecase wherre we have used the graph memgraph using docker to deploy it and created graphs and then created inference pipeline saved 20 minutes per medical coder and approximately of 3.5 million dollar savings as claims submission verifying on the payer side is a lengthy process
