🚀 Quick Start
Get up and running in 3 lines of code:
from transformers import pipeline
# Initialize the model
pipe = pipeline("text-generation", model="Soloman2002/hermit-code-7b")
# Start coding
chat = [{"role": "user", "content": "Write a Python function to reverse a linked list"}]
response = pipe(chat, max_new_tokens=512)
print(response[0]["generated_text"][-1]["content"])
💡 Tip: For best results, use
temperature=0.2andtop_p=0.95for deterministic code generation.

💻 Usage
Transformers
Perfect for prototyping and local development:
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch
# Load model and tokenizer
model_id = "Soloman2002/hermit-code-7b"
model = AutoModelForCausalLM.from_pretrained(
model_id,
torch_dtype=torch.bfloat16,
device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained(model_id)
# Prepare chat messages
messages = [
{"role": "system", "content": "You are Hermit Code, an expert coding assistant."},
{"role": "user", "content": "Write a Rust function that checks if a string is a palindrome."}
]
# Apply chat template
text = tokenizer.apply_chat_template(
messages,
tokenize=False,
add_generation_prompt=True
)
# Generate
inputs = tokenizer([text], return_tensors="pt").to(model.device)
outputs = model.generate(
**inputs,
max_new_tokens=512,
temperature=0.2,
do_sample=True
)
# Decode response
response = tokenizer.decode(
outputs[0][inputs.input_ids.shape[1]:],
skip_special_tokens=True
)
print(response)
vLLM (Recommended for Production)
For high-throughput serving and API deployment:
1. Install & Launch:
pip install vllm
vllm serve "Soloman2002/hermit-code-7b" --dtype bfloat16
2. Query via API:
curl -X POST "http://localhost:8000/v1/chat/completions" \
-H "Content-Type: application/json" \
-d '{
"model": "Soloman2002/hermit-code-7b",
"messages": [
{"role": "system", "content": "You are Hermit Code, a coding assistant."},
{"role": "user", "content": "Explain closures in JavaScript with examples."}
],
"temperature": 0.2,
"max_tokens": 512
}'
🚀 vLLM Benefits: Continuous batching, PagedAttention, and 10-20x throughput improvement over standard Transformers.
Inference API
Use Hugging Face's hosted infrastructure for instant access:
from huggingface_hub import InferenceClient
client = InferenceClient(token="hf_YOUR_TOKEN")
response = client.chat_completion(
model="Soloman2002/hermit-code-7b",
messages=[
{"role": "user", "content": "Write a Go function to merge two sorted arrays"}
],
max_tokens=512,
temperature=0.2,
stream=False
)
print(response.choices[0].message.content)

🐍 Python — Quick Sort Implementation
def quick_sort(arr: list[int]) -> list[int]:
"""
Sorts an array using the quicksort algorithm.
Time Complexity: O(n log n) average, O(n²) worst case
Space Complexity: O(log n) due to recursion
"""
if len(arr) <= 1:
return arr
pivot = arr[len(arr) // 2]
left = [x for x in arr if x < pivot]
middle = [x for x in arr if x == pivot]
right = [x for x in arr if x > pivot]
return quick_sort(left) + middle + quick_sort(right)
# Example usage
if __name__ == "__main__":
data = [3, 6, 8, 10, 1, 2, 1]
print(f"Original: {data}")

🐹 Go — Merge Sorted Arrays

// mergeSorted combines two sorted integer slices into a single sorted slice.
// It runs in O(n + m) time where n and m are the lengths of the inputs.
func mergeSorted(a, b []int) []int {
result := make([]int, 0, len(a)+len(b))
i, j := 0, 0
// Merge while both arrays have elements
for i < len(a) && j < len(b) {
if a[i] < b[j] {
result = append(result, a[i])
i++
} else {
result = append(result, b[j])
j++
}
}
// Append remaining elements
result = append(result, a[i:]...)
result = append(result, b[j:]...)
return result
}
func main() {
a := []int{1, 3, 5, 7}
b := []int{2, 4, 6, 8}
merged := mergeSorted(a, b)
fmt.Printf("Merged: %v\n", merged) // [1 2 3 4 5 6 7 8]
}

⚡ JavaScript — Closure Example
/**
* Creates a counter with private state using closures.
* Demonstrates lexical scoping and data encapsulation.
*/
function createCounter(initialValue = 0) {
let count = initialValue; // Private variable
return {
increment() {
count += 1;
return count;
},
decrement() {
count -= 1;
return count;
},
getValue() {
return count;
},
reset() {
count = initialValue;
return count;
}
};
}
// Usage
const counter = createCounter(10);
console.log(counter.increment()); // 11
console.log(counter.increment()); // 12
console.log(counter.getValue()); // 12
console.log(counter.reset()); // 10
Key Features Demonstrated:
- ✅ True private state via closures
- ✅ Clean object interface
- ✅ ES6 method shorthand syntax
- ✅ Default parameter values
