    • Dbt LLMsUse LLMs within your dbt environment to perform natural language processing tasks directly in your data transformation workflows, improving data analysis efficiency and effectiveness.

      You can enhance your dbt project by using large language models (LLMs) for processing unstructured text data. This can be particularly useful when dealing with data such as customer reviews, titles, descriptions, and Google Analytics sources, which may require categorization, sentiment analysis, or other natural language processing tasks. There are several ways to approach this, including using machine learning models or calling an LLM outside of the dbt flow. However, keeping these tasks inside your dbt environment as one of the dbt models is also an option, especially as Python dbt models continue to evolve. To get started, you'll need to set up your dbt project, which can be done by cloning the example project from GitHub and setting up your profiles.yml file. You'll also need to set up your database, such as Snowflake, and prepare your source data. Currently, dbt Python models only work with Snowflake, Databricks, and BigQuery, so keep that in mind. If you already have a dbt project and data, you can skip the setup section and jump to the guide on how to use the OpenAI API in your dbt project. By using LLMs within your dbt environment, you can perform natural language processing tasks directly in your data transformation workflows, making your data analysis more efficient and effective. For more information, check out the links provided in the text.

    • Preparing dataset for LLMs text classificationObtain OpenAI API key, set up external access integration in Snowflake, create/obtain categories, download/prepare dataset, update dbt project, set OpenAI API key, and set spending limit

      To work with large language models (LLMs) like OpenAI's API and use it for text classification tasks, you need to prepare your dataset and set up the necessary integrations. First, obtain the OpenAI API key and set up external access integration in Snowflake if you use it. Then, create or obtain a list of categories for your text classification task. You can create a list manually or let the LLM suggest categories based on a sample of your data. Manually creating a list ensures predictable and stable categories, while letting the LLM suggest categories can lead to less predictable results but may still be suitable depending on your use case. To download and prepare the dataset, use the metadata package from the tidy Tuesday repository or the lightweight version from the author's repository. Load the dataset into your database, update the dbt project to match your database and schema names, and set up the OpenAI API key in the Snowflake integration. Remember, the OpenAI API is pay-as-you-go, so you'll need to set a spending limit to avoid unexpected charges. Additionally, if you use Snowflake, make sure to set up external access integration for the OpenAI API to allow your dbt Python models to access it. Overall, preparing your dataset and setting up the necessary integrations are crucial steps to effectively use LLMs like OpenAI's API for text classification tasks.

    • OpenAI API in dbtSet temperature to 0, make model incremental, and turn off full refreshes to efficiently use OpenAI's API in a dbt Python model for text categorization and minimize costs.

      To ensure consistency in generating text categories using OpenAI's API in a dbt Python model, it's recommended to set the temperature parameter to 0 and make the model incremental to prevent unnecessary full refreshes and reduce API costs. First, let's prepare the base for the dbt model by setting up the config and connecting to the OpenAI API. We'll use the R package 'dataset' to extract package titles for categorization. In the dbt model, we can pass the dbt config via the backslash dot method and include package requirements. Next, we make the model incremental and turn off full refreshes to save on API costs. This will ensure that only new or changed data is categorized, preventing unnecessary repetition. Additionally, adding incrementality logic to the incremental run will further optimize the process. In summary, setting the temperature to 0, making the model incremental, and turning off full refreshes are crucial steps to effectively use OpenAI's API in a dbt Python model for text categorization while minimizing costs.

    • Text Classification OptimizationTo minimize costs and ensure stable results when processing large numbers of titles using OpenAI API for text classification, optimize by removing previously categorized titles, sending data in batches, using clear prompts, and being aware of OpenAI API pricing

      To process a large number of titles from a dataset using OpenAI API for text classification, it's essential to optimize the process to minimize costs and ensure stable results. Here are some key strategies: 1. Remove previously categorized titles from each run, except the first one, to avoid redundant processing. 2. Send data to OpenAI API in batches to reduce costs. A batch size of 5 titles works well. 3. Use clear and concise prompts to avoid repetition and SQL injections. 4. Be aware of OpenAI API pricing, which is based on the number of tokens requested and returned. 5. Use tools like Tiktokken to estimate token usage or the official OpenAI tokenizer to evaluate the cost of specific texts. For instance, with a dataset of approximately 18,000 titles, the total input tokens would be around 320,000, and the output tokens would be approximately 140,000 if we use a batch size of 5. The costs for the full scan would be around $1.4 for the smaller model and $3.6 for the larger model. To summarize, optimizing the text classification process involves removing previously categorized titles, sending data in batches, using clear prompts, and being aware of OpenAI API pricing to minimize costs and ensure stable results.

    • DBT model efficiency and growing R usageThe DBT model efficiently categorized 18,000 packages, with R being the most popular data visualization tool and increasing in use as a data processing tool. The most significant growth occurred in 2019, and alternative approaches could save costs but require more engineering effort. The model should focus on one job and use JSON output for stability.

      The DBT model effectively categorized all 18,000 packages without any gaps, proving to be cost-efficient and protective against multiple dbt runs. The top category, accounting for 6%, highlights the popularity of R as a data visualization tool, particularly with packages like Shiny and Plotly. The top two growing categories in 2023 suggest R's increasing use as a data processing tool. The most significant year-to-year growth among the top 30 categories occurred in 2019, following the release of influential papers like "Attention is All You Need" and "GPT." Moving forward, alternative approaches like GPT embeddings could be explored for cost savings, although they require more engineering effort. It's also advisable to consider removing this part from dbt and pushing it to cloud functions or other infrastructure. The model should focus on one job, and adding logic could lead to rerunning it, which should be avoided, especially in multiple developer environments. Additionally, using a response with a delimiter can be unstable, as the response might not provide the expected number of elements, making it challenging to map initial titles to the list of categories. To address this, requiring JSON output is recommended, as it allows for a more stable and predictable response format, even though it will be more expensive due to increased response size.

    • JSON switch impact on classification qualitySwitching to JSON for gpt3 led to decreased classification quality, but an alternative solution using Cortex in Snowflake was effective. Joel Labas' dbt blog post provides the full code and resources for further exploration.

      The switch to JSON for gpt3 resulted in a significant decrease in classification quality. However, an alternative solution exists using Cortex in Snowflake. For those interested, Joel Labas wrote a comprehensive post about this issue on the dbt blog. The post includes the full code on GitHub for reference. Additionally, there are links to a Tableau public dashboard and the tidy Tuesday r dataset for further exploration. Overall, this Hackernoon story highlights the importance of considering alternative solutions when encountering unexpected issues with data processing tools.
