📊 Live Measured Benchmark Scorecard (Official Public Test Sets)

All evaluations below were run directly on the actual model weights (model.safetensors, 791.15M params) on an NVIDIA RTX 3060 GPU against official datasets downloaded live from Hugging Face:

Every raw question, prompt, model output, and ground truth label is serialized in checkpoints/official_public_verifiable_benchmark_log.json.

⚠️ Known Failures & Root Causes

1. MMLU Mathematics Failure (5.00%):
   • The model severely underperforms on formal high school competition mathematics.
   • Cause: Pretrained parameter scale ($791\text{M}$) lacks the symbol-manipulation capacity of 70B+ models without deep multi-step chain-of-thought fine-tuning.
2. Context Window Ceiling ($2,048$ tokens):
   • Cannot process multi-file SWE-Bench repositories or long document analysis.

💻 Quickstart Inference

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "clevrpwn/gmma-jepa"

# Load tokenizer and model directly from Hugging Face
tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    dtype=torch.bfloat16,
    device_map="auto",
    trust_remote_code=True
)

prompt = "Question: An astronomer observes that a planet rotates faster after a meteorite impact. Which is the most likely effect?\nAnswer:"
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=32)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
