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.

Do we have an official score running the model on HLE?
There was a problem hiding this comment.
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
…t directory - Simplified unsupported parameter handling in OpenAIEngine from 210 to 132 lines - Removed complex parse_openai_error_for_unsupported_param function and duplicate code - Extracted common logic into single _fix_unsupported_param helper method - Fixed HLE evaluation script to always output to examples/deepresearch/hle_outputs/ - Ensures outputs go to gitignored location regardless of where script is run This addresses reviewer feedback about overly complex error handling with code duplication. Tested with GPT-4o and O3-mini models. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
- Remove .ruff.toml (not needed, project uses global config) - Remove ALIGNMENT_ANALYSIS.md (internal development notes) These were temporary files used during development to track alignment with Tongyi's original implementation. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
