# llama-eval Implementation Summary
## Overview
Simple evaluation tool for llama.cpp with support for multiple datasets (AIME, GSM8K, GPQA) and flexible grading (regex, CLI, LLM).
## Key Features
- **Multiple Datasets**: AIME, GSM8K, GPQA with proper answer extraction
- **Flexible Grading**: Regex, CLI, or LLM-based grading
- **Parallel Processing**: Configurable thread count for concurrent requests
- **Sampling Parameters**: Temperature, Top K, Top P, Min P (optional)
- **Real-time Feedback**: Progress tracking with detailed output
- **JSON Output**: Complete eval state saved for debugging
- **GPQA Support**: Answer shuffling with reproducible results
## Architecture
### Eval State
```python
@dataclass
class EvalState:
id: str
tasks: List[str]
task_states: Dict[str, Dict[str, Any]]
sampling_config: Dict[str, Any]
```
### Processor
- Handles processing, grading, and state management
- Thread-safe concurrent execution
- Configurable sampling parameters
### Grader
- Abstract grading interface supporting multiple types
- Regex grader with dataset-specific patterns
- CLI grader with external script interface
- LLM grader with configurable server and model
### Datasets
- `AimeDataset`: 90 AIME 2025 questions
- `Aime2025Dataset`: 30 AIME 2025 I & II questions
- `Gsm8kDataset`: 7473 math word problems
- `GpqaDataset`: 198 GPQA Diamond questions with shuffling
## Configuration
### Sampling Parameters (Optional)
- `--temperature`: Sampling temperature
- `--top-k`: Top K sampling
- `--top-p`: Top P sampling
- `--min-p`: Min P sampling
- Only passed if explicitly specified
### Grading Types
- **regex**: Built-in patterns for each dataset
- **cli**: External script with `--answer` and `--expected` args
- **llm**: LLM-based extraction with few-shot examples and configurable server/model
### Dataset Requirements
- **AIME**: Supports regex, CLI, or LLM grader
- **AIME2025**: Supports regex, CLI, or LLM grader
- **GSM8K**: Supports regex, CLI, or LLM grader
- **GPQA**: Requires LLM grader
## Output Format
### Progress Table
```
Task ID Dataset Prompt (first 43 chars) Expected Status
aime_000_001 AIME Complete the following reactions and sel... A pending
```
### Results Summary
```
============================================================
Results: 8/10 correct (80.0%)
============================================================
```
### JSON Output
Complete eval state with task IDs, correctness, prompts, extracted answers, and sampling configuration.
## Technical Details
- Default max tokens: -1 (infinite)
- Default grader type: llm
- Default seed: 1234
- Default threads: 32
- Prompt truncation: First 43 chars + padding + "..."
- Response truncation: Last 10 lines for grading
- GPQA requires LLM grader (returns letter A/B/C/D)
- Judge model defaults to evaluated model if not specified
- Sample answers defined in SAMPLE_ANSWERS dict for few-shot learning
