- This improves latency of @general chat by avoiding unnecessary
compute
- It also avoids passing references in API response when they haven't
been used to generate the chat response. So interfaces don't have to
add logic to not render them unnecessarily
- **Introduce Khoj to LangChain**:
Call GPT with LangChain for Khoj Chat
- **Search (and Chat about) PDF files with Khoj**
- Create PDF to JSONL Processor: Convert PDF content into standardized JSONL format
- Expose PDF search type via Khoj server API
- Enable querying PDF files via Obsidian, Emacs and Web interfaces
- Make plugin update khoj server config to index PDF files in vault too
- Make Obsidian plugin update index for PDF files in vault too
- Show PDF results in Khoj Search modal as well
- Ensure combined results are sorted by score across both types
- Jump to PDF file when select it PDF search result from modal
- Match argument names passed to khoj openai completion funcs with
arguments passed to langchain calls to OpenAI
- This simplifies the logic in the khoj openai completion funcs
- Fix bug where both LangChain and Khoj retry requests 6 times each.
So a total of 12 requests at >1minute intervals for each chat
response in case of OpenAI API being down
- Retrying too many times when the API is failing doesn't help
- The earlier 60 second request timeout was spacing out the interval
between retries way too much. This slowed down chat response times
quite a bit when API was being flaky
- With these updates you'll know if call to chat API failed in under a
minute
- Use ChatModel and ChatOpenAI to call OpenAI chat model instead of
using OpenAI package directly
- This is being done as part of migration to rely on LangChain for
creating agents and managing their state
### Objective:
Use telemetry to better understand Khoj usage.
This will motivate and prioritize work for Khoj.
Specific questions:
- Number of active deployments of khoj server
- How regularly is khoj used (hourly, daily, weekly etc)?
- How much is which feature used (chat, search)?
- Which UI interface is used most (obsidian, emacs, web ui)?
### Details
- Expose setting to disable telemetry logging in khoj.yml
- Create basic telemetry server to log data to a DB
- Log calls to Khoj API /search, /chat, /update endpoints
- Batch upload telemetry data to server at ~hourly interval
- Khoj chat will now respond to general queries if:
1. no relevant reference notes available or
2. when explicitly induced by prefixing the chat message with "@general"
- Previously Khoj Chat would a lot of times refuse to respond to
general queries not answerable from reference notes or chat history
- Make chat quality tests more robust
- Add more equivalent chat response options refusing to answer
- Force haiku writing to not give any preable, just the haiku
- Simplifies switching between different OpenAI chat models. E.g GPT4
- It was previously hard-coded to use gpt-3.5-turbo. Now it just
defaults to using gpt-3.5-turbo, unless chat-model field under
conversation processor updated in khoj.yml
