* FEATURE: Embeddings to main db
This commit moves our embeddings store from an external configurable PostgreSQL
instance back into the main database. This is done to simplify the setup.
There is a migration that will try to import the external embeddings into
the main DB if it is configured and there are rows.
It removes support from embeddings models that aren't all_mpnet_base_v2 or OpenAI
text_embedding_ada_002. However it will now be easier to add new models.
It also now takes into account:
- topic title
- topic category
- topic tags
- replies (as much as the model allows)
We introduce an interface so we can eventually support multiple strategies
for handling long topics.
This PR severely damages the semantic search performance, but this is a
temporary until we can get adapt HyDE to make semantic search use the same
embeddings we have for semantic related with good performance.
Here we also have some ground work to add post level embeddings, but this
will be added in a future PR.
Please note that this PR will also block Discourse from booting / updating if
this plugin is installed and the pgvector extension isn't available on the
PostgreSQL instance Discourse uses.
This change-set connects GPT based chat with the forum it runs on. Allowing it to perform search, lookup tags and categories and summarize topics.
The integration is currently restricted to public portions of the forum.
Changes made:
- Do not run ai reply job for small actions
- Improved composable system prompt
- Trivial summarizer for topics
- Image generator
- Google command for searching via Google
- Corrected trimming of posts raw (was replacing with numbers)
- Bypass of problem specs
The feature works best with GPT-4

* FIX: Remove `null: false` from dropped column
It's causing an issue when attempting to seed data in fresh installs.
The column was dropped in a post-migration.
* Update db/migrate/20230322142028_make_dropped_value_column_nullable.rb

A prompt with multiple messages leads to better results, as the AI can learn for given examples. Alongside this change, we provide a better default proofreading prompt.
We switched to negative integers for seeded prompts, but we also
need to delete the old ones using IDs 1/2/3 if they exist,
or deploys will fail due to the unique index on the name column.
This change adds two new reviewable types: ReviewableAIPost and ReviewableAIChatMessage. They have the same actions as their existing counterparts: ReviewableFlaggedPost and ReviewableChatMessage.
We'll display the model used and their accuracy when showing these flags in the review queue and adjust the latter after staff performs an action, tracking a global accuracy per existing model in a separate table.
* FEATURE: Dedicated reviewables for AI flags
* Store and adjust model accuracy
* Display accuracy in reviewable templates
