| ``` | |
| ### LLM Stack | |
| - **Model**: GPT-5 family (nano/mini/main for different use cases) | |
| - **Context Window**: 128K tokens | |
| - **Function Calling**: Tool-based orchestration | |
| - **Temperature**: 0.5 (balanced accuracy/creativity) | |
| - **Max Tokens**: 4096 (prevents truncation on detailed queries) | |
| --- | |
| ## 📊 Optimizations Implemented | |
| ### 1. Smart Context Reduction | |
| - Extracts only essential fields: Title, Deadline, Funding, Description (200 words), Eligibility (150 words) | |
| - Reduces token usage: 2000+ → 300-500 tokens | |
| - Impact: 84-90% token reduction per grant | |
| ### 2. Batch Summarization | |
| - Processes 5 grants per API call (configurable) | |
| - Parallel async processing with semaphore-based concurrency | |
| - New `get_all_grant_summaries()` tool for single-call batch operations | |
| - Impact: 30 grants in ~20 seconds vs ~7 minutes sequential | |
| ### 3. Query Caching | |
| - In-memory SummaryCache with 1-hour TTL | |
| - Deterministic hashing of grant context | |
| - Automatic expiration and cleanup | |
| - Impact: 365,000x speedup on repeated queries | |
| ### 4. Streaming (Planned) | |
| - Backend supports `stream=True` for token-by-token delivery | |
| - Gradio UI limitations prevent real-time streaming display | |
| - Can be enhanced with custom websocket implementation | |
| ### 5. Parallel Processing | |
| - `asyncio.gather()` for concurrent API calls | |
| - Semaphore-based rate limiting | |
| - Results stream as they complete | |
| ### 6. Model Optimization | |
| - Using GPT-5 variants: nano (routing), mini (translation/summaries), main (complex analysis) | |
| - Context extraction reduces API cost per query | |
| - Batch processing reduces total API calls | |
| --- | |
| ## 🔧 System Prompt Strategy | |
| The system prompt is highly engineered to control LLM behavior: | |
| ```python | |
| "WHEN USER ASKS FOR:" | |
| "- 'description/summaries of all/every grant' → IMMEDIATELY call get_all_grant_summaries (ONE SINGLE TOOL CALL)" | |
| "- 'description/summaries of grants' → IMMEDIATELY call summarize_grants_batch" | |
| "CRITICAL RULES:" | |
| "- DO NOT make multiple tool calls. Make ONE tool call and wait for results." | |
| "- DO NOT return raw JSON lists when user asks for descriptions/summaries" | |
| "- DO NOT say 'I will do X' and then stop. ACTUALLY CALL THE TOOL." | |
| "- NEVER omit tool results from your response" | |
| ``` | |
| This prevents: | |
| - ❌ LLM promising to do work without executing | |
| - ❌ Sequential tool calls instead of batch operations | |
| - ❌ Raw JSON output instead of formatted summaries | |
| --- | |
| ## 🔄 Tool Pipeline | |
| ### User Query → Response Flow | |
| 1. **User Message** → Added to message history | |
| 2. **LLM Call** → With available tools and system prompt | |
| 3. **Tool Selection** → LLM chooses best tool | |
| 4. **Tool Execution** → In `_dispatch_tool()` handler | |
| - `get_all_grant_summaries()` - All grants in one call | |
| - `summarize_grants_batch()` - Multiple specific grants | |
| - `summarize_grant()` - Single grant detail | |
| - `list_grants()` - Just IDs/titles (no descriptions) | |
| - `search_grants()` - Filter by keyword/criteria | |
| - `compare_grants()` - Side-by-side comparison | |
| 5. **Result Formatting** → Tool results formatted as markdown | |
| 6. **Final LLM Call** → LLM generates response with tool results | |
| 7. **Response Display** → Formatted markdown to user | |

| ## 📝 Recent Improvements | |
| ### Session Latest (Oct 27, 2025) | |
| **Problem**: User requested descriptions of all grants and got: | |
| - Raw JSON list of 36 grants | |
| - Promise: "Now I will get detailed descriptions..." | |
| - No actual summaries returned on first request | |
| **Root Cause**: LLM was calling `list_grants()` then promising `summarize_grants_batch()` without executing in single interaction. | |
| **Solution Implemented**: | |
| 1. **New Tool**: `get_all_grant_summaries(batch_size=5)` | |
| - Gets ALL grant IDs automatically | |
| - Batches summarization internally | |
| - Returns complete results in ONE tool call | |
| - Added to `chat_tools.py` (lines 240-267) | |
| 2. **Tool Schema**: Updated `tool_schemas.py` (lines 201-222) | |
| - Registered `get_all_grant_summaries` for OpenAI function calling | |
| 3. **Handler**: Added in `demo_app.py` (lines 228-265) | |
| - Collects async results | |
| - Formats as readable markdown | |
| - Returns complete summaries | |
| 4. **System Prompt**: Updated to explicitly direct LLM | |
| - "call get_all_grant_summaries (ONE SINGLE TOOL CALL)" | |
| - "DO NOT make multiple tool calls" | |
| - "NEVER show list_grants output when user asks for descriptions" | |
| **Result**: Single tool call, no raw JSON, immediate detailed summaries | |
| --- | |
| ## 🎯 Common Patterns | |
| ### Getting All Grant Summaries (Fastest) | |
| ``` | |
| User: "give me a description of all grant opportunities" | |
| LLM: Calls get_all_grant_summaries() → Returns 36 formatted summaries | |
| Time: ~20-30 seconds | |
| ``` | |
| ### Searching for Specific Grants | |
| ``` | |
| User: "what grants are about battery innovation?" | |
| LLM: Calls search_grants("battery innovation") → Returns matching grants | |
| LLM: Calls summarize_grants_batch(grant_ids) → Returns summaries | |
| ``` | |
| ### Comparing Two Grants | |
| ``` | |
| User: "compare competition-2313 and competition-2314" | |
| LLM: Calls compare_grants("2313", "2314") → Returns side-by-side | |
| ``` | |
| --- | |
| ## 🔍 Data Structure | |
| ### Grant JSON Schema | |
| ```json | |
| { | |
| "id": "competition-2313", | |
| "title": "Battery Innovation Feasibility Studies Round 1", | |
| "deadline": "2025-12-17T11:00:00", | |
| "status": "open", | |
| "funding_min": 0, | |
| "funding_max": 250000, | |
| "description": "...", | |
| "eligibility": "...", | |
| "scope": "..." | |
| } | |
| ``` | |
| **Total Grants**: 36 active + closed opportunities | |
| **Data Source**: `data/snapshots/` - 28+ individual JSON files | |
| **Last Updated**: 2025-10-27 | |

| ## 🛠️ Environment Setup | |
| ```bash | |
| # Required | |
| export OPENAI_API_KEY=sk-... | |
| # Optional | |
| export ANTHROPIC_API_KEY=sk-ant-... | |

| ✅ Single-tool-call batch summarization (get_all_grant_summaries) | |
| ✅ Query caching with TTL | |
| ✅ Context extraction reducing tokens 84-90% | |

| --- | |
| ## 🤔 Known Limitations | |
| 1. **Gradio UI** doesn't display real-time streaming (backend supports it) | |
| 2. **MaxTokens** truncation on very detailed multi-grant queries (mitigation: increased to 4096) | |
| 3. **Context window** for 36+ grants approaching limits (mitigation: smart context reduction) | |
