Project mention: Major Technologies Worth Learning in 2025 for Data Professionals | dev.to | 2024-12-07Artificial Intelligence (AI) is becoming a ubiquitous, and dare I say, indispensable part of data workflows. Tools like ChatGPT have made it easier to review data and write reports. But diving even deeper, tools like DataRobot, H2O.ai, and Google’s AutoML are also simplifying machine learning pipelines and automating repetitive tasks, enabling professionals to focus on high-value activities like model optimization and data storytelling. Mastering these tools will not only boost productivity but also ensure you remain competitive in an AI-first world.

txtai
💡 All-in-one open-source AI framework for semantic search, LLM orchestration and language model workflows
-
Choosing the right embedding model is equally important for effective semantic matching of queries and chunk blocks. To select the appropriate open-source embedding model, the authors conducted another experiment using the evaluation module of FlagEmbedding, which uses the dataset namespace-Pt/msmarco7 for queries and the dataset namespace-Pt/msmarco-corpus8 for the corpus and metrics like RR and MRR were used for evaluation.

prompttools
Open-source tools for prompt testing and experimentation, with support for both LLMs (e.g. OpenAI, LLaMA) and vector databases (e.g. Chroma, Weaviate, LanceDB).
LLM answer quality directly relates to its given prompts, and therefore, effective prompt engineering is necessary. The landscape of prompt managing platforms and libraries increased manifold. Some tools now actively incorporate specific tweaks of the most recent commercial models, enabling the formulation of prompts that are injected with model-specific formulations. Example libraries are dspy, LMQL, Outlines, and Prompttools,
