To build an LLM-powered system that accesses up-to-date news articles and stock prices, the best approach is tocreate an agentthat has access to specific tools (option D).

Agent with SQL and Web Search Capabilities:By using an agent-based architecture, the LLM can interact with external tools. The agent can query Delta tables (for up-to-date stock prices) via SQL and perform web searches to retrieve the latest news articles. This modular approach ensures the system can access both structured (stock prices) and unstructured (news) data sources dynamically.

Why This Approach Works:

SQL Queries for Stock Prices: Delta tables store stock prices, which the agent can query directly for the latest data.

Web Search for News: For news articles, the agent can generate search queries and retrieve the most relevant and recent articles, then pass them to the LLM for processing.

Why Other Options Are Less Suitable:

A (Summarizing News for Stock Prices): This convoluted approach would not ensure accuracy when retrieving stock prices, which are already structured and stored in Delta tables.

B (Stock Price Volatility Queries): While this could retrieve relevant information, it doesn't address how to obtain the most up-to-date news articles.

C (Vector Store): Storing news articles and stock prices in a vector store might not capture the real-time nature of stock data and news updates, as it relies on pre-existing data rather than dynamic querying.

Thus, using an agent with access to both SQL for querying stock prices and web search for retrieving news articles is the best approach for ensuring up-to-date and accurate responses.

The task requires an open generative AI model for a transcription (speech-to-text) task where speed is essential. Let’s assess the options based on their suitability for transcription and performance characteristics, referencing Databricks’ approach to model selection.

Option A: Llama-2-70b-chat-hf

Llama-2 is a text-based LLM optimized for chat and text generation, not speech-to-text. It lacks transcription capabilities.

Databricks Reference:"Llama models are designed for natural language generation, not audio processing"("Databricks Model Catalog").

Option B: MPT-30B-Instruct

MPT-30B is another text-based LLM focused on instruction-following and text generation, not transcription. It’s irrelevant for speech-to-text tasks.

Databricks Reference: No specific mention, but MPT is categorized under text LLMs in Databricks’ ecosystem, not audio models.

Option C: DBRX

DBRX, developed by Databricks, is a powerful text-based LLM for general-purpose generation. It doesn’t natively support speech-to-text and isn’t optimized for transcription.

Databricks Reference:"DBRX excels at text generation and reasoning tasks"("Introducing DBRX," 2023)—no mention of audio capabilities.

Option D: whisper-large-v3 (1.6B)

Whisper, developed by OpenAI, is an open-source model specifically designed for speech-to-text transcription. The “large-v3” variant (1.6 billion parameters) balances accuracy and efficiency, with optimizations for speed via quantization or deployment on GPUs—key for the application’s requirements.

Databricks Reference:"For audio transcription, models like Whisper are recommended for their speed and accuracy"("Generative AI Cookbook," 2023). Databricks supports Whisper integration in its MLflow or Lakehouse workflows.

Conclusion: OnlyD. whisper-large-v3is a speech-to-text model, making it the sole suitable choice. Its design prioritizes transcription, and its efficiency (e.g., via optimized inference) meets the speed requirement, aligning with Databricks’ model deployment best practices.
