AI Chat System Verification Findings

Date: 2025-10-10 Status: 🟡 Partially Operational - Configuration Issue Found

Executive Summary

The AI chat vector database is fully operational with 116 Bible versions across 47 languages, all with complete embeddings. However, there is a critical configuration issue with the Azure OpenAI API deployments that prevents the chat from functioning.

---

✅ What's Working

1. Vector Database Infrastructure (100% Operational)

• Database Connection: PostgreSQL 17.5 ✓
• pgvector Extension: v0.8.0 installed ✓
• Schema: ai_bible schema exists ✓

2. Bible Vector Tables (116 Tables - Fully Populated)

Metric	Value
Total Vector Tables	116
Languages Supported	47
Embedding Coverage	100% for all tables
Table Structure	Correct (all have embedding, tsv, ref, text_raw, etc.)

Sample Table Statistics:

• bv_ab_aau: 7,923 verses (100% embedded)
• bv_ac_aca: 4,406 verses (100% embedded)
• bv_ac_acr_acc: 7,930 verses (100% embedded)

3. Languages Available

The system currently supports 47 languages including:

• English (en): 9 versions (ASV, Brenton, KJV, KJV2006, LXX2012, RV, T4T, UK_LXX2012, WEB_C)
• German (de): 2 versions
• Dutch (nl): 3 versions
• French (fr): 1 version
• And 43+ other languages

Note: User requested support for Romanian (ro), Spanish (es), and Italian (it) but these languages are NOT found in the vector database. This is a critical gap.

4. Current Vector Search Implementation

The existing code in /root/biblical-guide/lib/vector-search.ts already implements:

• ✅ Multi-table search across all versions for a given language
• ✅ Hybrid search (vector + full-text)
• ✅ Language-based table filtering
• ✅ Proper query pattern: bv_{lang}_{version}

---

❌ What's Broken

1. Azure OpenAI API Configuration (CRITICAL)

Problem: The deployment names in .env.local do not exist in the Azure OpenAI resource.

Environment Variables:

AZURE_OPENAI_DEPLOYMENT=gpt-4o  # ❌ Deployment NOT FOUND (404)
AZURE_OPENAI_EMBED_DEPLOYMENT=embed-3  # ❌ Deployment NOT FOUND (404)

Error Message:

DeploymentNotFound: The API deployment for this resource does not exist.

Impact:

• Chat API cannot generate responses
• Embedding generation fails
• Vector search cannot create query embeddings

2. Missing Priority Languages

User Requirements: Romanian (ro), Spanish (es), Italian (it)

Current Status:

• ❌ Romanian (ro): NOT in vector database
• ❌ Spanish (es): NOT in vector database
• ❌ Italian (it): NOT in vector database

Available Languages: The current 47 languages are mostly obscure languages (ab, ac, ad, ag, etc.) and do NOT include the user's priority languages.

🔧 Required Fixes

Priority 1: Fix Azure OpenAI Deployments (IMMEDIATE)

Action Required:

1. Identify the correct deployment names in the Azure OpenAI resource
2. Update .env.local with correct values:
   • AZURE_OPENAI_DEPLOYMENT=<actual-chat-deployment-name>
   • AZURE_OPENAI_EMBED_DEPLOYMENT=<actual-embedding-deployment-name>

Options to Find Correct Deployment Names:

• Option A: Check Azure Portal → Azure OpenAI → Deployments
• Option B: Contact Azure admin who created the resource
• Option C: Check deployment history/documentation

Expected Deployment Patterns:

• Chat: Usually named like gpt-4, gpt-4-32k, gpt-35-turbo, etc.
• Embeddings: Usually named like text-embedding-ada-002, text-embedding-3-small, etc.

Priority 2: Add Priority Language Vector Tables (HIGH)

Missing Tables Needed:

-- Romanian versions
ai_bible.bv_ro_cornilescu    (Cornilescu Bible)
ai_bible.bv_ro_fidela        (Fidela Bible - mentioned in BIBLE_MD_PATH)

-- Spanish versions
ai_bible.bv_es_rvr1960       (Reina-Valera 1960)
ai_bible.bv_es_nvi           (Nueva Versión Internacional)

-- Italian versions
ai_bible.bv_it_nuovadiodati  (Nuova Diodati)
ai_bible.bv_it_nuovariveduta (Nuova Riveduta)

Action Required:

1. Verify if these Bible versions exist in source data
2. Create embeddings for each version
3. Import into ai_bible schema with proper naming

Priority 3: Implement English Fallback (MEDIUM)

Current Behavior:

• Search only looks in language-specific tables (e.g., only bv_ro_* for Romanian)
• If language not found, returns empty results

Required Behavior:

1. Search in primary language tables first
2. Check result quality (min 3 results, top similarity > 0.75)
3. If insufficient → fallback to English (bv_en_* tables)
4. Return combined results with language indicators

Implementation: Already planned in /root/biblical-guide/AI_CHAT_FIX_PLAN.md

📊 Current System Architecture

Vector Search Flow (Working)

User Query
    ↓
getEmbedding(query)  ❌ FAILS HERE - Deployment Not Found
    ↓
searchBibleHybrid(query, language, limit)
    ↓
getAllVectorTables(language)  ✓ Returns tables like ["ai_bible.bv_en_eng_kjv", ...]
    ↓
For each table:
    - Vector similarity search (embedding <=> query)
    - Full-text search (tsv @@ plainto_tsquery)
    - Combine scores (0.7 * vector + 0.3 * text)
    ↓
Sort by combined_score and return top results

Chat API Flow (Partially Working)

User Message
    ↓
[Auth Check] ✓ Working
    ↓
[Conversation Management] ✓ Working
    ↓
generateBiblicalResponse(message, locale, history)
    ↓
searchBibleHybrid(message, locale, 5)  ❌ FAILS - Embedding API 404
    ↓
[Build Context with Verses] ✓ Would work if embeddings worked
    ↓
[Call Azure OpenAI Chat API] ❌ FAILS - Chat API 404
    ↓
[Save to Database] ✓ Working

🎯 Implementation Plan

Phase 1: Fix Azure OpenAI (Day 1 - URGENT)

1. Identify Correct Deployments

   • Check Azure Portal
   • List all available deployments in the resource
   • Document deployment names and models

2. Update Environment Configuration

   • Update .env.local with correct deployment names
   • Verify API version compatibility
   • Test connection with verification script

3. Validate Fix

   • Run npx tsx scripts/verify-ai-system.ts
   • Confirm both Chat API and Embedding API pass
   • Test end-to-end chat flow

Phase 2: Add Priority Languages (Days 2-3)

1. Romanian (ro)

   • Source Bible data for Cornilescu and Fidela versions
   • Create embeddings using Azure OpenAI
   • Import into ai_bible.bv_ro_cornilescu and ai_bible.bv_ro_fidela

2. Spanish (es)

   • Source Bible data for RVR1960 and NVI
   • Create embeddings
   • Import into respective tables

3. Italian (it)

   • Source Bible data for Nuova Diodati and Nuova Riveduta
   • Create embeddings
   • Import into respective tables

Phase 3: Implement Fallback Logic (Day 4)

1. Update searchBibleHybrid Function

   • Add quality check logic
   • Implement English fallback
   • Add language indicators to results

2. Update Chat API Response

   • Include source language in citations
   • Inform user when fallback was used
   • Format: [KJV - English fallback] John 3:16

Phase 4: Testing (Day 5)

1. Test Each Language

   • Romanian queries → Romanian results
   • Spanish queries → Spanish results
   • Italian queries → Italian results
   • Unsupported language → English fallback

2. Test Edge Cases

   • Empty results handling
   • Mixed language queries
   • Very specific vs. general queries

3. Performance Testing

   • Query response time (target < 2s)
   • Multi-table search performance
   • Concurrent user handling
