-## 🤝 Collaboration Welcome (But Not Required)
+**🤝 Collaboration welcome:**
+Looking for teammates with complementary skills:
+- **Systems engineers**: Distributed sandbox architecture with load balancing
+- **Compute sponsors**: Academic institutions or cloud providers for training runs
+- **Experimenters**: End-to-end validation and benchmarking on mathematical reasoning tasks
 
-I'm perfectly happy working on this solo, but collaboration can be rewarding when there's mutual value and good fit.
-
-### 🛠️ Areas Where I'd Value Expertise
-
-**Distributed Sandbox Engineering:**
-- Asynchronous code execution environment with load balancing
-- Worker pool architecture for parallel code execution
-- Systems engineering and containerization expertise
-
-**Dataset Engineering:**
-- Mathematical reasoning dataset curation and validation
-- Cold-start data pipeline design
-- Quality control and formatting workflows
-
-### 🚀 Collaboration Approach
-
-- **Start small:** Open an issue to discuss your approach first
-- **Show, don't tell:** Small proof-of-concept before larger contributions
-- **Quality focused:** Code review and documentation required
-- **Clear attribution:** All substantial contributors get proper credit
-
-### 💰 The Compute Reality
-
-**Full training requires significant resources:**
-- ~8x A100s for complete AIME validation
-- Currently exploring compute sponsorship options
-- Happy to validate on smaller models first
-
-### 🎯 What I'm Looking For
-
-- People who bring complementary skills (not just ML knowledge)
-- Contributors who can work independently and deliver quality
-- Collaborative mindset without drama or politics
-
-**Interested?** Open an issue with your background and what you'd like to work on. Let's see if there's a good fit! 
-
-*No pressure though - I genuinely enjoy the solo research implementation process too.* 😊
