@cernus76, @jmsrpp @seeobjectively, this topic is already covered at https://architecture.learning.sap.com/docs/ref-arch/e5eb3b9b1d/5 and updated with my latest PR #733.

@seeobjectively, please merge your content into the existing RA

[seeobjectively]

@kay-schmitteckert I've switched to the subpage 'deep dive' approach we discussed, I expect the this page will grow as more partnerships/patterns emerge. I've also added a link on the parent page to navigate for more details that looks like this -

For a detailed guide on building code-based agents, including deployment approaches with Kyma Runtime, LLM access patterns using LiteLLM, and framework-specific implementation details, see Building Code-Based Agents.

Let me know what you think.

@jmsrpp, I heard back from @kay-schmitteckert on this and he's okay with us going ahead with this. He's eventually going to refactor all the GenAI/Agents pages. Could you take a look at this change?

[cernus76]

Side note: I discussed this with Kay, and we might move the content to a new RA focused on agents.

Hi @seeobjectively,
Thank you for the changes. Just a request, as per TechEd it was quoted as Pro code agents rather than Code based agents.
Can we make the change to this RA? Have aligned with @kay-schmitteckert on the naming convention.

Let me know what you think.
