- Jupyter Notebook for Java
Lately I've been working on Langgraph4J which is a Java implementation of the more famous Langgraph.js which is a Javascript library used to create agent and multi-agent workflows by Langchain. Interesting note is that [Langchain.js] uses Javascript Jupyter notebooks powered by a DENO Jupiter Kernel to implement and document How-Tos. So, I faced a dilemma on how to use (or possibly simulate) the same approach in Java and, without much hope, I started looking for a Jupyter Kernel that supported Java considering that, from the JDK 9 version, there was the introduction of JShell that enabled the REPL for Java.
- What is OpenLLM and what problem does it solve?
LangChain: This suggests a tool or framework for chaining together different NLP (Natural Language Processing) tasks. With LangChain integration, you can create multi-step workflows that combine OpenLLM's capabilities with other NLP tools for more advanced tasks.

Langchain and the implementation of Custom Tools also is a great (and very efficient) way to setup a dedicated Q&A (for example for chat purpose) agent.

- Claude 2 Internal API Client and CLI
We're using it via langchain talking to Amazon Bedrock which is hosting Claude 1.x. It's comparable to GPT3.x, not bad. The integration doesn't seem to be fully there though, I think langchain is expecting "Human:" and "AI:", but Claude uses "Assistant:".

- Any better alternatives to fine-tuning GPT-3 yet to create a custom chatbot persona based on provided knowledge for others to use?
Depending on how much work you want to put into it, you can get started at HuggingFace with their models and datasets, but you'd need compute power, multiple MLOps, etc. I was introduced to the concept in this video, since Google has their Vertex AI tools on Google Cloud, and there's always LangChain but I'm not sure about anything recent.

Semantic Kernel
- Building AI-Powered Applications with C# and Semantic Kernel
But how do you build these AI-powered applications effectively? Enter Semantic Kernel: an open-source SDK from Microsoft designed to simplify the integration of powerful large language models (LLMs) like GPT into your applications.

- Build a C# Console Chatbot with Semantic Kernel & Azure OpenAI
Semantic Kernel (SK) is a lightweight library that helps your code talk to language models. It works with Azure OpenAI, Azure AI Foundry models like Mixtral or Phi‑3, and even local models. The key benefits are:
- Model context protocol server prompts with microsoft semantic kernel
This post focuses on implementing server prompts, a key feature of the Model Context Protocol (MCP) designed for reusable template definitions. We will explore how to implement these server prompts using both the MCP C# SDK and Semantic Kernel for enhanced templating capabilities. Further details on MCP server prompts can be found in the MCP documentation.
- AWS Bedrock anthropic claude tool call integration with microsoft semantic kernel
As of April 2025, the official Microsoft Semantic Kernel connector for Amazon Microsoft.SemanticKernel.Connectors.Amazon does not natively support tool/function calls. Apparently, Semantic Kernel is shifting its approach towards an LLM abstraction layer based on Microsoft.Extensions.AI, aiming for a more unified and extensible architecture. Currently, only OpenAI and Ollama implementations are available within this new abstraction. It is anticipated that an implementation for AWS Bedrock Anthropic Claude based on Microsoft.Extensions.AI will become available in the future. Therefore, in the interim, I implemented a custom solution. The approach leverages the existing IChatClient interface, making the implementation relatively straightforward. Since function calls are supported by this interface, the solution involves implementing it on top of the AWS Bedrock Runtime SDK.
