Official Support for Newer Models for Agent Builder

Per the official documentation only four models can be used for the watsonx Orchestrate Agent Builder.

Of the four models, only one has not yet been deprecated by watsonx Orchestrate.

The remaining model, llama-3-2-90b-vision-instruct, is more than one year old. Many clients, including Verizon, have long since moved on to llama 3.3 series models (9+ months old) and llama 4 series models (5+ months old), and newer models will continue to be released. Therefore, this Idea request is for select newer models to be supported for Agent Builder features going forward.

Given that obviously not all models will be suitable for the Agent Builder features, no specific model's support is requested. Restrictions on which newer models will be supported are reasonable and expected. This Idea is requesting that some newer models be supported in general, both immediately and in the ongoing future, and that IBM publish a list of these models for clients to pick from to continue to leverage Agent Builder features on newer models.  If a specific "first model to official support" is desired, the client would like gpt-oss-120b officially supported, but that is not a hard requirement. Other newer models could be acceptable and yet newer models will need to be added as they are released down the road.

    A few are being benchmarked right now, those who pass should make it to the agent builder in 4Q:

    gpt-oss-120b

    gpt-oss-20b

    Llama4 Maverick

    Worth noting that it is possible to use other models, albeit those available on WatsonX.ai only, by the use of the ADK.

    For example, we are using gpt-oss-120b for one agent, admittedly test only, but it is there. Command in the ADK is:

    orchestrate models add --name "watsonx/openai/gpt-oss-120b" --app-id waxai_gw_creds
