Prompt engineering is a relatively new discipline that gained popularity in the early 2020s as researchers and practitioners sought to optimize the performance of large language models (LLMs) like GPT-3 and GPT-4.

Introduction

Welcome to the product section of our knowledge base! This section is aimed at users of our platform and is designed to provide you with an in-depth understanding of each of our products.

The chat allows you to send prompts to different AI models and receive a response based on that. This guide explains how to use the model without additional tools.

Model without tools

To access specific knowledge in files, you can use the document search tool. Simply upload or connect a file and you will take the document into account.

Document Search

AI Models have a date when their knowledge ends, because they can not learn over time or save information. To access information from after that period (or simply include web results), you can use the web search tool.

Web Search

A few models are capable of processing images and taking them into account for their answer generation. This can be used to extract text, describe or analyse images.

Image Analysis (Vision)

To generate images based on your text input, you can use the image generation tool. Here, the model you selected sends a prompt to another model, which is built to generate images (most times Dall-E3).

Image Generation

To process tabular files like CSVs, Google Sheets or Excel Sheets, you can use the data analyst / python tool. Here is how to use it.

Data Analysis

To select a model and interact with the messages and responses in the chat, there are a few functionalities in the chat. These are the model selector in the top left corner and the buttons to interact with prompts and responses.

Basic Chat functionalities

Canvas allows editing code or text in a dedicated screen next to a chat and iterating more easily on the output.

Canvas

If you developed a good prompt and want to reuse it in the future, there is a prompt library to store it. You can edit it, share it with others, and use it easily in a chat or with an assistant. Prompts in the prompt library are always stored within folders. You can keep your folders private or share your folders with other users in the workspace.

Prompt Library

Assistants are chatbots you can set up for a specific situation or to work with a specific document. It works similarly to the chat, with the difference that you save documents and instructions to refer to the assistant without setting the chat up again.

Introduction to Assistants

There are different tools you can ue to configure the assistant and tailor it to your specific use case.

Assistant Configuration

Creates a model response for a given Assistant.

Assistant API

Retrieve all available models for use with the Assistant API.

Models for Assistant API

Upload Attachment API

Creates a model response for the given chat conversation using an OpenAI model.

OpenAI Chat completion

Creates a model response given a structured list of input messages using the Anthropic API.

Langdock Search is a functionality that allows users to search files, pages, and content across all connected tools.

Introduction to Search

The Account Settings include all preferences and adjustments for a specific user. They only apply to this specific user and no one else. The account settings can be set by any user.

Account Settings

The workspace settings apply to multiple users, usually the entire workspace. This is only accessible for admins (except groups if the admins allow individual users to create groups).

Workspace Settings

Knowledge folders can contain several hundred files and can be attached to an assistant. Below is a guide how to use this feature and where the difference is compared to attaching files directly to the assistant.

Upload a file to a knowledge folder

Update a file in a knowledge folder

Retrieve files from a knowledge folder

Delete a file from a knowledge folder

Search through all files in data folders shared with the API Key

Actions allow you to integrate any tool through an API to an assistant. This gives you a very large range of opportunities. Below you find a short introduction of how to use it.

How to create Actions

Salesforce

Let an assistant perform actions to Google Drive.

Google Drive Actions

Let an assistant perform actions in Jira, like reading and writing issues.

Jira Actions

Langdock has limits of prompts per user per time frame to ensure that all users can use all models at any time.

Fair Usage Policy

By default, users use API keys from Langdock. You can optionally use your own API keys instead.

Bring your own Keys (BYOK)

To use your own models and not the flat fee of Langdock, BYOK needs to be activated. This section guides you through the process of adding your own models.

BYOK setup

In the model settings, admins can add their own AI models.

Adding your own models

One of our core-values is to build a tool which is model-agnostic. That means, that we do not want to trap the user in one model, but give the choice which model to use. Each model has different strengths and we encourage you to test the different models to find the best models for your specific need.

Model Guide

Provide custom instructions to improve responses.

Custom instructions

This guide shows you how to build an assistant. We will use an example of a job description assistant, but the steps and considerations can be used with any use case.
