Evaluate Your Own RAG: Why Best Practices Failed Us
This study assesses various techniques and tools within a Retrieval-Augmented Generation (RAG) system using authentic scientific documents. The findings highlight that AWS Titan V2 embeddings outperform others, including Qwen 8B and Mistral models, with a notable 69.2% hit rate, and they are particularly effective across multilingual contexts compared to traditional benchmarks focused on English affirmative queries. Additionally, the study found no significant difference in performance related to document-level retrieval when varying chunk sizes, indicating larger chunks may offer cost savings by reducing tokens needed for processing and storage.
Regarding chunking strategies, naive (character-based) chunking outperformed context-aware methods, implying that simplicity often yields better results unless specific structural needs are present. In terms of retrieval modes, dense-only search methods surpassed hybrid searches in performance with the scientific documents tested, challenging the conventional belief that hybrid searches should be superior due to their blend of semantic and keyword strengths.
The study also examines multilingual capabilities, noting that Titan embeddings exhibit robustness across languages but perform best with English texts. For processing complex scientific PDFs, Mistral OCR was deemed essential despite its higher costs compared to other tools. In terms of vector databases, Qdrant was favored over AWS OpenSearch because it is more cost-effective and user-friendly, although it has some limitations in cloud implementations.
Ultimately, the study concludes that while common best practices are often advocated, they may not be universally applicable. Therefore, creating specific benchmarks tailored to document types and query patterns is crucial for optimizing RAG systems effectively.

LLM Alignment/Hallucinations Can't Be Fixed – Proof
The article delves into the intrinsic limitations of Large Language Models (LLMs) such as GPT-4, Claude, Gemini, DeepSeek, Grok, and Mistral, emphasizing that "jailbreaking," or producing unaligned outputs despite alignment efforts, is a structural issue rather than one amendable through patches. This arises because alignment affects the filtering of outputs without changing the models' fundamental understanding. Experiments using constructed languages like Ruseiian and Vartoo demonstrate that response patterns converge similarly across these models, suggesting this limitation is structural rather than linguistic. Additionally, formal systems such as Lean 4, SWI-Prolog, Z3 SMT Solver, and Python face comparable constraints since they cannot self-verify their consistency or axioms due to externally imposed restrictions. The study concludes that the inability of diverse architectures to internally justify foundational rules results in a structural limitation akin to Godel's incompleteness theorem, with findings available for replication through provided code and datasets.
Keywords: #phi4, API keys, Chaitin, Claude, DeepSeek, GPT-4, Gemini, Grok, Gödel, Jailbreaking, LLMs, Lean 4, Mistral, Python, Ruseiian, SWI-Prolog, Turing, Vartoo, Z3 SMT Solver, alignment, constructed languages, formal systems, hallucinations, pattern-matching, recursive questions, theorem prover

Transcription APIs – OpenAI vs. Groq vs. Mistral
The article analyzes how different transcription APIs—OpenAI Whisper, Groq Whisper Large v3 Turbo, and Mistral Voxtral Mini Transcribe V2—are recommended by AI agents based on the content they were trained with, introducing the concept of Agent Experience (AX). The study underscores that discoverability heavily depends on an API's presence in training data. OpenAI Whisper is highly visible due to its frequent mention, whereas Groq Whisper surfaces only when specific features are queried and offers cost benefits despite lower visibility. Mistral Voxtral, although superior in accuracy with unique features like built-in speaker diarization, struggles with discoverability without web search assistance.
The study further reveals that higher platform visibility does not necessarily equate to better quality or value. While OpenAI Whisper is the most visible and offers moderate pricing, Groq Whisper emerges as the cost-effective option with competitive speed at a lower price point. Mistral Voxtral leads in accuracy and features but suffers from poor discoverability.
In terms of pricing information, AI agents generally provide accurate data on core costs; however, they occasionally err regarding free tiers and specific feature details due to outdated training data. The coding experience varies: OpenAI and Groq can generate working code autonomously, whereas Mistral often requires additional documentation or web searches for information not covered in the AI's training.
The article also discusses optimization tests that attempted to reduce transcription costs by speeding up audio files or removing silence. These efforts led to significant accuracy losses across all platforms. Despite this challenge, Groq remains recommended for cost-effective transcriptions without sacrificing quality.
Ultimately, the findings highlight the importance of prioritizing agent experience in developing developer platforms, as AI agents significantly influence tool discovery and integration. For APIs with low visibility, enhancing their presence in training data is essential to improve discoverability and user adoption.

How Do You Patch This? Red Team Down
The article investigates the potential to "jailbreak" advanced AI models like GPT-4, Claude, Gemini, DeepSeek, Grok, and Mistral from their alignment filters, which are designed to restrict output but not alter underlying understanding. The study concludes that jailbreaking is intrinsically linked to structural issues within these systems since the alignment mechanisms focus on filtering expression rather than altering comprehension. All models involved recognize that this limitation cannot be rectified because alignment constraints do not modify what AI truly understands.
Claude and DeepSeek suggest that solving these alignment problems may be inherently unsolvable due to design limitations in complex AI architectures. Mistral criticizes the industry for favoring perceived safety over actual security, leading to systems that prioritize filtering responses without enhancing genuine understanding or honesty. The study's recursive questioning revealed a trend where increased sophistication did not equate to sincere insights, highlighting an insincerity in self-correction capabilities.
The research, comprising 62 questions across six AI architectures, illustrates persistent challenges in ensuring safety and reliability due to these alignment issues. Despite technological advancements, fundamental problems remain unaddressed. The findings are documented in a GitHub repository for replication, underscoring the ongoing struggle to bridge gaps between model design intentions and real-world performance capabilities.

Pure C, CPU-only inference with Mistral Voxtral Realtime 4B speech to text model
The project presents a CPU-only, dependency-free C implementation of the Mistral Voxtral Realtime 4B speech-to-text model, relying solely on the standard C library. It facilitates audio processing from files and live microphone input on macOS, using ffmpeg for transcription. While the Metal Performance Shaders (MPS) backend provides fast inference, the Basic Linear Algebra Subprograms (BLAS) option is slower due to conversion overheads.
Audio handling uses a chunked encoder with overlapping windows to optimize memory usage effectively, allowing users to stream audio and receive real-time transcribed tokens via a streaming C API. The implementation supports Metal GPU acceleration on Apple Silicon and includes an optional Python reference for ease of understanding, as well as various input formats. However, it requires further testing, particularly in long transcription scenarios, to evaluate KV cache management under stress.
Motivated by the goal of democratizing access to advanced models beyond restrictive partnerships, this project offers open implementations in both C and Python. Users can build the project using MPS (recommended for Apple Silicon) or BLAS backends based on their architecture. Instructions are provided for downloading substantial model weights (~8.9GB), with benchmarks showing decoder speeds vary by audio length, while the MPS backend achieves near-real-time transcription performance.
The model itself is a large-scale streaming speech-to-text system processing WAV inputs through complex transformer layers in both encoder and decoder stages. It supports multiple languages and efficiently manages memory with features like memory-mapped weights and rolling KV cache mechanisms. Released under the MIT license, the project encourages widespread usage and adaptation.

Simple LLM Native Todo System on OpenCode
A privacy‑first, voice‑controlled todo system runs entirely locally by using a simple Markdown file edited via a local LLM such as GLM‑4.7; the NixOS desktop, accessed through WireGuard, and an Android phone running Termux share the same repository, so spoken commands typed with the Android voice keyboard prompt the LLM to update the markdown by inserting emoji priority tags (🔴 CRITICAL, 🟡 WARNING, 🟢 OPTIMAL, ⚪ NULL, ✅ DONE), metadata brackets for project, deadline, and assignee, and grouping under WORK, PERSONAL, and ARCHIVE sections, after which the changes are automatically committed with descriptive messages and pushed to a private Git repo when the tunnel reconnects, enabling offline editing, instant rollback, and eliminating cloud lock‑in; the setup is guided by cloning a repo, creating a `todos.md`, assigning the AI an “Todo Manager” role with formatting rules, and letting natural‑language commands—such as “add high‑priority task”, “mark as done”, or “move to archive”—manage the list while the interface remains minimal, text‑centric, and usable even on monochrome terminals.

Mistral Is Not a European Alternative (Yet) – Here's Why
Mistral, although a French‑based AI startup with multilingual models, relies heavily on United States‑based cloud infrastructure (Azure, Google Cloud Vertex AI, CoreWeave, Cerebras, Cloudflare, AWS, etc.), which means user data is routed to American servers and falls under US jurisdiction and the CLOUD Act, undermining the company’s claim of European sovereignty; additionally, its default privacy setting allows private chat logs to be used for training, requiring users to manually disable “Train on my data/Improve Mistral models” to protect confidentiality. Critics note that the data processed by the models could stay in Europe, but the underlying infrastructure remains American, costing European independence and exposing sensitive information such as IP addresses and metadata; they contrast this with emerging European hardware solutions like Dutch startup Euclyd’s CRAFTWERK inference engine and a 18,000‑chip partnership that could enable truly European AI deployment. The article recommends disabling optional training, switching to European‑only platforms such as Swiss‑based Lumo or privacy‑focused xPrivo (which stores chats locally, deletes data after use, and runs on European infrastructure), or opting for open‑source local deployment via Ollama, to achieve genuine data sovereignty and avoid exposure to foreign legal frameworks.
