pg_vectorize: a VectorDB for Postgres

A Postgres extension that automates the transformation and orchestration of text to embeddings and provides hooks into the most popular LLMs. This allows you to do vector search and build LLM applications on existing data with as little as two function calls.

This project relies heavily on the work by pgvector... See more

Introduction

VT.ai is a multi-modal AI Chatbot Assistant, offering a chat interface to interact with Large Language Models (LLMs) from various providers. Both via remote API or running locally with Ollama.

The application supports multi-modal conversations, seamlessly integrating text, images, and vision processing with LLMs.

So many ingredients of sunscreen can pass through the blood brain barriers. You should go for ones with minerals that reflect sunlight.

In Young brains the process happens automatically:1. Epinephrine to increase alterness2. Asidocoline to increase focus. Ability to focus on the error margin between what you did and what your goal was.3. Dopamine once you decrease your errors to speed up plasticity.

Token Embeddings: These are vector representations of tokens, which can be characters, subwords, or other text units. Token embeddings are particularly useful in languages with complex morphology or when handling out-of-vocabulary words. Models like BERT use token embeddings to represent subword units.

Word Embeddings: These are dense vector... See more

The context size of the input is too small for when you want to analyse CSV's with 1000's of rows and embedding doesn't really work because it loses context.

Developers can now generate human-quality speech from text via the text-to-speech API. Our new TTS model offers six preset voices to choose from and two model variants, tts-1 and tts-1-hd . tts is optimized for real-time use cases and tts-1-hd is optimized for quality. Pricing starts at $0.015 per input 1,000 characters. Check out our TTS guide to... See more

Powerful AI systems can help us interpret the neurons of weaker AI systems. And those interpretability insights often tell us a bit about how models work. And when they tell us how models work, they often suggest ways that those models could be better or more efficient. —Dario Amodei, Anthropic
