This pull request introduces a significant refactor to how language models are referenced and handled across the codebase, moving from a legacy enum-based approach to a more flexible string-based "model slug" system. It also upgrades the OpenAI client library to v3 and updates configuration to use a new inference service. Additionally, several new models are now supported, and the handling of conversation history has been modernized for better compatibility and extensibility.
Key changes include:
Model Handling and API Changes:
Replaced the use of the deprecated
LanguageModelenum throughout the API with a newmodelSlugstring field, updating all relevant function signatures and data structures to use the new approach. This includes fallback logic for backward compatibility. (internal/api/chat/create_conversation_message_stream.go,internal/api/chat/create_conversation_message_stream_helper.go,internal/models/conversation.go,internal/api/mapper/conversation.go) [1] F51da0ccL99, F51da0ccL165, F51da0ccL208, F51da0ccL236, [2] [3]Upgraded the OpenAI client from v2 to v3 and refactored all usages and data types accordingly, including the way chat history is stored and sent.

OpenAIBaseURL,OpenAIAPIKey) to more generic inference service fields (PDInferenceBaseURL,PDInferenceAPIKey) throughout the codebase and tests. (internal/libs/cfg/cfg.go,internal/libs/cfg/cfg_test.go) [1] F5f06866L19, F5f06866L29, [2]Codebase Cleanup:
CreateConversationMessagemethod and its supporting code, consolidating all conversation message creation through the streaming API. (internal/api/chat/create_conversation_message_stream_helper.go)These changes modernize the model selection process, improve extensibility for future models and providers, and align the codebase with the latest OpenAI client and internal infrastructure.
