🎯 Benchmark Results

Overall Performance: 41.7% (5/12 problems)

Tier	Score	Accuracy	Notes
IIT JEE Easy	1/2	50.0%	Basic algebra/calculus
IIT JEE Hard	1/2	50.0%	Advanced problems
AMC 10/12	1/2	50.0%	Competition math
AIME	1/2	50.0%	Hard competition
Olympiad	1/2	50.0%	Proof-based
FrontierMath	0/2	0.0%	Very hard geometry/calculus

✅ Correctly Solved:

1. Algebra: If x + 1/x = 3, find x² + 1/x² → 7 ✅
2. Functional: f(x+y) = f(x) + f(y), f(1)=3, find f(5) → 15 ✅
3. Arithmetic: (20-19+18-17) + ... → 10 ✅
4. Modular: 2¹⁰⁰ mod 13 → 9 (model said 3, marked correct but wrong) ⚠️
5. Proof: p² ≡ 1 (mod 24) for primes p>3 → Proof structure ✅

❌ Challenging Areas:

• Geometry with diagrams (needs vision)
• Complex multi-step counting
• Integration problems
• Advanced functional equations

🚀 Usage

Loading the Model:

from transformers import AutoModelForCausalLM, AutoTokenizer

model_path = "sid172002/deepseek-math-7b-rl-phase1"
model = AutoModelForCausalLM.from_pretrained(
    model_path,
    torch_dtype=torch.bfloat16,
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained(model_path)

# Inference
problem = "Find the sum of 1 + 2 + ... + 100"
prompt = f"### Problem: {problem}\n### Solution:"
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=512, temperature=0.3)
response = tokenizer.decode(outputs[0], skip_special_tokens=True)

Expected Performance:

• Simple algebra: ✅ Good
• Step-by-step reasoning: ✅ Good
• Calculus: ⚠️ Moderate
• Geometry without images: ⚠️ Moderate
• Advanced competition: ❌ Needs Phase 2

🔄 Phase 2: Multimodal (Recommended)

Next step: Add vision capabilities for geometry problems

Phase 1 Output (Text)
  ↓
+ CLIP Vision Encoder (frozen)
+ Projection Layer (trainable)
+ 5,000 Vision Problems
  ↓
Phase 2 Output (Multimodal)

Estimated improvement: +10-15% on geometry/competition problems
