Google introduces Gemini 3, its most intelligent AI model, enhancing reasoning and multimodal capabilities. It outperforms previous models in benchmarks and is available across Google products like the Gemini app, AI Studio, and Vertex AI.
This article explains how to set up a Home Assistant voice assistant that mimics GLaDOS's voice and personality, using add-ons like Whisper and Piper for speech synthesis and recognition.
This article details how to set up a custom voice pipeline in Home Assistant using free self-hosted tools like Whisper and Piper, replacing cloud-based services for full control over speech-to-text and text-to-speech processing.
A tutorial on building a private, offline Retrieval Augmented Generation (RAG) system using Ollama for embeddings and language generation, and FAISS for vector storage, ensuring data privacy and control.
1. **Document Loader:** Extracts text from various file formats (PDF, Markdown, HTML) while preserving metadata like source and page numbers for accurate citations.
2. **Text Chunker:** Splits documents into smaller text segments (chunks) to manage token limits and improve retrieval accuracy. It uses overlapping and sentence boundary detection to maintain context.
3. **Embedder:** Converts text chunks into numerical vectors (embeddings) using the `nomic-embed-text` model via Ollama, which runs locally without internet access.
4. **Vector Database:** Stores the embeddings using FAISS (Facebook AI Similarity Search) for fast similarity search. It uses cosine similarity for accurate retrieval and saves the database to disk for quick loading in future sessions.
5. **Large Language Model (LLM):** Generates answers using the `llama3.2` model via Ollama, also running locally. It takes the retrieved context and the user's question to produce a response with citations.
6. **RAG System Orchestrator:** Coordinates the entire workflow, managing the ingestion of documents (loading, chunking, embedding, storing) and the querying process (retrieving relevant chunks, generating answers).

Code Wiki is a platform that maintains a continuously updated, structured wiki for code repositories, aiming to improve developer productivity by unlocking knowledge buried in source code. It features automated documentation, intelligent context-aware chat, and integrated actionable links.
OpenAI releases GPT-5.1 Instant and GPT-5.1 Thinking, upgrades to the GPT-5 series focusing on improved intelligence, conversational style, and customization options for ChatGPT. Includes new tone presets and the ability to fine-tune characteristics.
LLMs are powerful for understanding user input and generating human‑like text, but they are not reliable arbiters of logic. A production‑grade system should:
- Isolate the LLM to language tasks only.
- Put all business rules and tool orchestration in deterministic code.
- Validate every step with automated tests and logging.
- Prefer local models for sensitive domains like healthcare.
| **Issue** | **What users observed** | **Common solutions** |
|-----------|------------------------|----------------------|
| **Hallucinations & false assumptions** | LLMs often answer without calling the required tool, e.g., claiming a doctor is unavailable when the calendar shows otherwise. | Move decision‑making out of the model. Let the code decide and use the LLM only for phrasing or clarification. |
| **Inconsistent tool usage** | Models agree to user requests, then later report the opposite (e.g., confirming an appointment but actually scheduling none). | Enforce deterministic tool calls first, then let the LLM format the result. Use “always‑call‑tool‑first” guards in the prompt. |
| **Privacy concerns** | Sending patient data to cloud APIs is risky. | Prefer self‑hosted/local models (e.g., LLaMA, Qwen) or keep all data on‑premises. |
| **Prompt brittleness** | Adding more rules can make prompts unstable; models still improvise. | Keep prompts short, give concrete examples, and test with a structured evaluation pipeline. |
| **Evaluation & monitoring** | Without systematic “evals,” failures go unnoticed. | Build automated test suites (e.g., with LangChain, LangGraph, or custom eval scripts) that verify correct tool calls and output formats. |
| **Workflow design** | Treat the LLM as a *translator* rather than a *decision engine*. | • Extract intent → produce a JSON/action spec → execute deterministic code → have the LLM produce a user‑friendly response. <br>• Cache common replies to avoid unnecessary model calls. |
| **Alternative UI** | Many suggest a simple button‑driven interface for scheduling. | Use the LLM only for natural‑language front‑end; the back‑end remains a conventional, rule‑based system. |
