💠 Zenyx-42M: Where Calm Meets Power
Zenyx-42M is a 42M parameter GPT-2 style decoder-only transformer
trained from scratch
on high-quality educational web text.
The name "Zenyx" fuses
Zen
(calm, focused intelligence) and
Onyx
(strength, power)—embodying an efficient, capable language model.

Capabilities
✅ Text completion
✅ Topic consistency
✅ Grammar & syntax
✅ Technical vocabulary
⚠️ Base model (fine-tuning required for instructions)
⚠️ 512 token context
Usage
Install dependencies
pip install torch transformers tokenizers
Quick Start Example
import torch
from model import NanoGPT
from config import NanoGPTConfig
from tokenizers import Tokenizer
# Load model
checkpoint = torch.load('best_model.pt' , map_location='cpu' , weights_only=False )
config = checkpoint['config' ]
model = NanoGPT(config)
model.load_state_dict(checkpoint['model' ])
model.eval ()
# Load tokenizer
tokenizer = Tokenizer.from_file('tokenizer.json' )
def generate (prompt, max_tokens=100 , temperature=0.6 ):
tokens = tokenizer.encode(prompt).ids
x = torch.tensor(tokens).unsqueeze(0 )
with torch.no_grad():
output = model.generate(x, max_new_tokens=max_tokens, temperature=temperature, top_k=40 )
return tokenizer.decode(output.tolist())
prompt = "Artificial intelligence is"
output = generate(prompt)
print (output)
Limitations
⚠️ Base model only (no instruction fine-tuning)
⚠️ Can repeat phrases (use repetition penalty)
⚠️ 512 token context window
⚠️ Small parameter count limits knowledge
⚠️ Possible factual errors
⚠️ Not suitable for reliable code generation
Not recommended for:
❌ Production applications (without fine-tuning)
❌ Factual QA
❌ Instruction following
❌ Mission-critical tasks
Fine-Tuning
Designed as a
base model
for further fine-tuning.
Next Steps:
Instruction fine-tuning (Alpaca/Dolly datasets)
Code specialization (GitHub/StackOverflow)
Domain adaptation (medical/legal/etc)
RLHF (human feedback alignment)
Ethical Considerations
Training data may contain bias
Intended for educational/experimental use
Not suitable for high-stakes decisions
Fully open source and documented
No explicit safety fine-tuning
