In my previous article, I presented a [comparison of GPT-4o and Claude 3.5 Sonnet for multi-label text classification](https://www.daniweb.com/programming/computer-science/tutorials/542629/openai-gpt-4o-vs-claude-3-5-sonnet-for-multi-label-text-classification). The accuracies achieved by both models were relatively low. Fine-tuning is one solution to overcome the low performance of large-language models. With fine-tuning, you can incorporate custom domain knowledge into an LLM's …

I had some fun this weekend having a go at pdfkit with mixed results. Can anyone nominate a candidate for best PDF writing?

On April 14, 2025, OpenAI released [GPT-4.1](https://openai.com/index/gpt-4-1/) — a model touted as the new state-of-the-art, outperforming GPT-4o on all major benchmarks. As always, I like to evaluate new LLMs on simple tasks like text classification and summarization to see how they compare with current leading models. In this article, I …

Large language models are trained on a fixed corpus, and their knowledge is often limited by the documents they are trained on. Techniques like retrieval augmented generation, continuous pre-training, and fine-tuning enhance an LLM's default knowledge. However, these techniques can still not enable an LLM to answer queries that require …

Hi everyone, I'm Hichem. A web developer, Python enthusiast and problem solver. I'm happy to be a member of the DaniWeb community.

This tutorial demonstrates how to build an AI agent that queries SQLite databases using natural language. You will see how to leverage the [LangGraph framework](https://www.langchain.com/langgraph) and the [OpenAI GPT-4o](https://openai.com/index/gpt-4/) model to retrieve natural language answers from an SQLite database, given a natural language query. So, let's begin without ado. ## …
