yayashuxue · 2025-09-19T05:03:54Z

Summary

Integrates Tongyi's DeepResearch ReAct agent into rLLM for academic benchmarks (HLE). Provides universal model support with automatic adaptation for any OpenAI-compatible API.

Key Features

Agent Implementation

MultiTurnReactAgent: Full Tongyi ReAct loop with hybrid approach
- Native OpenAI function calling for models that support it (e.g., O3)
- XML <tool_call> format fallback for other models (e.g., GPT-4o)
- Works with any OpenAI-compatible API (OpenAI, Together AI, vLLM, etc.)
Automatic parameter mapping: Handles model-specific requirements seamlessly (Note: to make OpenAI Engine automatically and smartly route all parameters, we have discussed to do a standalone PR later)
Accurate token counting: Uses API response tokens for precise context management

Production-Ready Tools

Search: Web search via Serper API with Google Custom Search fallback
Scholar: Google Scholar search through Serper API
Visit: Web page content extraction with BeautifulSoup
FileParser: Multi-format support (TXT, JSON, CSV, PDF, DOCX)
PythonInterpreter: Secure code execution with 50s timeout

Evaluation Pipeline

HLE benchmark support with parallel execution
Configurable judge model with binary yes/no scoring
Current accuracy: 26.67% (consistent with reported HLE difficulty)

Technical Highlights

Universal compatibility: Works with any OpenAI-compatible model
Automatic adaptation: Detects and handles model-specific requirements
Parallel execution: Concurrent task processing via AgentWorkflowEngine
Episode format: Outputs rLLM Episodes for training pipeline integration

@jeffreysijuntan please review it

Key fixes: - Replace GPT-2 tokenizer with API token consumption tracking to fix context limit errors - Fix infinite loops caused by incorrect token counting (was using 1024 limit for 128k models) - Use actual API response.prompt_tokens and response.completion_tokens for accurate tracking Improvements: - Add comprehensive HLE evaluation script with judge-based scoring - Update README to accurately reflect tool implementation status (Scholar/Visit are placeholders) - Apply ruff linting and formatting to all files - Clean up verbose debug prints while keeping useful status indicators - Add better error handling and timeout management The token counting issue was causing false "context exceeded" errors at ~13k tokens when models actually support 128k. This led to incorrect message truncation and infinite loops where the model would repeat the same response. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>

All tools are now fully functional with real implementations: - Search & Scholar: Use Serper API for Google/Scholar search (ported from Tongyi) - Visit: Fetches and parses webpages with requests/BeautifulSoup - FileParser: Enhanced to support TXT, JSON, CSV, PDF (PyPDF2), DOCX (python-docx) - PythonInterpreter: Safe execution environment with timeout (already working) The tools were ported directly from the original Tongyi DeepResearch implementation to provide production-ready functionality instead of placeholders. This enables the agent to perform real research tasks with actual web search, paper lookup, webpage analysis, and multi-format file parsing capabilities. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>

…ng models - Auto-detect and fix unsupported API parameters via error parsing - Automatically remap max_tokens -> max_completion_tokens for o3/o1/gpt-5 - Remove unsupported sampling params (temperature, top_p, presence_penalty, etc.) - Cache parameter fixes to avoid repeated warnings (log once per engine instance) - Support future OpenAI models without code changes (try-catch-adapt pattern) - Allow up to 10 parameter adjustments per request for reasoning models This enables seamless usage of reasoning models (o3, o1, gpt-5, future models) in rLLM workflows without manual parameter configuration.

- Fix token counter not resetting between tasks (caused early context limit) - Fix Python tool missing exception classes in restricted environment - Add scipy submodule support for scientific computing - Fix o3 model handling when outputting both tool_call and answer - Process tool calls before checking for answers to support o3 behavior - Add better truncation for base64 images and long outputs - Improve error handling in evaluation rating parsing These fixes significantly improve evaluation quality and consistency. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>

Major changes: 1. Vision Support (multimodal images): - Added image handling in evaluate_hle.py extract_qa function - Modified deepresearch_workflow.py to pass images to agent - Updated deepresearch_agent.py to construct multimodal messages with image_url - Images are sent as base64 data URLs to vision-capable models (e.g., gpt-4o) - No changes needed to OpenAIEngine (natively supports multimodal messages) 2. Alignment Documentation: - Added ALIGNMENT_ANALYSIS.md with detailed comparison to Tongyi's DeepResearch - Updated README.md with source alignment mapping table 3. Code Cleanup: - Removed original reference files (react_agent_original.py, tool_*_original.py) - These were kept for reference but are now documented in ALIGNMENT_ANALYSIS.md - Added hle_outputs/* and intermediate files to .gitignore Vision support enables the agent to process HLE questions with images (e.g., chess boards) without requiring external file parsing, directly leveraging GPT-4o's vision capabilities.

+# DeepResearch Integration for rLLM


Do we have an official score running the model on HLE?

do you mean the tongyi model? i don't have the model spun up but if we do we can run the full hle and get the score). for the GPT o3 15 samples we got 26.7% on HLE

Integrates Tongyi DeepResearch into rLLM framework with: 1. Auto-detection of native function calling for O3/O1 models 2. Model-specific API parameter handling: - O3/O1: max_completion_tokens only - GPT-4: full params (stop, temperature, top_p, max_tokens, presence_penalty) - Qwen: temperature, top_p, max_tokens - Fallback: conservative minimal params 3. Cleanup: Remove temporary analysis files This keeps OpenAI engine unchanged and handles all model-specific compatibility at the DeepResearch application layer. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>

Don't set default sampling_params in the engine for evaluation. DeepResearch handles model-specific parameters internally based on model capabilities (O3/O1 vs GPT-4 vs Qwen). This fixes O3 errors where engine's max_tokens was conflicting with DeepResearch's max_completion_tokens. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>

Bug in upstream v0.2: text variable was only set when reasoning exists, causing 'cannot access local variable text' error for GPT-4o and other non-reasoning models. Fix: Set text = content when reasoning is not available. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>

Restores full hybrid mode from 9f04d36 and adds comprehensive O3 support: 1. OpenAI Engine (minimal changes): - Support max_completion_tokens parameter (O3/O1 requirement) - Backward compatible with max_tokens (GPT-4, etc.) - Fix undefined text variable for non-reasoning models 2. DeepResearch Agent (from 9f04d36 + enhancements): - Hybrid mode: Native function calling (O3) + XML format (GPT-4o) - Model-specific API parameters (O3/GPT-4/Qwen/fallback) - Show internal reasoning for O3 models - Default use_native_function_calling=False (auto-enabled by workflow) 3. DeepResearch Workflow: - Auto-detect O3/O1 models to enable native function calling 4. Evaluation Script: - No default sampling_params for evaluation (DeepResearch handles it) - Judge supports O3 with max_completion_tokens - Judge response method uses correct parameters per model Tested with O3-mini and GPT-4o - both working with multi-round execution. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>

Replace legacy 1-5 rating system with binary yes/no judgment to align with Tongyi DeepResearch's HLE evaluation approach. Changes: - Judge prompt: Binary correct/incorrect evaluation - Parsing: Extract yes/no instead of rating - Metrics: Remove rating-related fields - Summary: Simplified output without rating distribution 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>

Extract duplicate max_tokens logic into _prepare_max_tokens_param helper. Reduces code duplication between chat_completion and completion methods. Net change: -1 line, cleaner code structure. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
