# ApexCoder-1.5B · Merged 16-bit Model
|
||||
|
||||
*Last updated: 2026-03-20 — Cycle 2*
|
||||
|
||||
Production-ready merged model (base + LoRA fused into 16-bit weights).
|
||||
Trained on a single NVIDIA A40 (44 GB) using Unsloth QLoRA + TRL SFTTrainer.
|
||||
|
||||
> **Looking for a smaller download?**
|
||||
> Use the [LoRA adapter](Gianloko/apex-coder-1.5b-lora) (~150 MB) or the
|
||||
> [GGUF Q4_K_M](Gianloko/apex-coder-1.5b-GGUF) (~986 MB) for Ollama.

|
||||
|
||||
|
||||
## 🚀 Quick start
|
||||
|
||||
```python
|
||||
from transformers import AutoModelForCausalLM, AutoTokenizer
|
||||
import torch
|
||||
|
||||
model = AutoModelForCausalLM.from_pretrained(
|
||||
"Gianloko/apex-coder-1.5b",
|
||||
torch_dtype=torch.bfloat16,
|
||||
device_map="auto",
|
||||
)
|
||||
tokenizer = AutoTokenizer.from_pretrained("Gianloko/apex-coder-1.5b")
|
||||
|
||||
messages = [
|
||||
{"role": "system", "content": "You are ApexCoder, a world-class Salesforce expert."},
|
||||
{"role": "user", "content": "Write a bulkified Apex trigger on Opportunity that prevents status changes to Closed Won if no related Products exist."},
|
||||
]
|
||||
inputs = tokenizer.apply_chat_template(
|
||||
messages, return_tensors="pt", add_generation_prompt=True
|
||||
).to(model.device)
|
||||
|
||||
output = model.generate(inputs, max_new_tokens=512, temperature=0.1, do_sample=False)
|
||||
print(tokenizer.decode(output[0][inputs.shape[1]:], skip_special_tokens=True))
|
||||
```
|
||||
|
||||
## 🦙 Ollama (GGUF — recommended for local use)
|
||||
|
||||
```bash
|
||||
ollama pull hf.co/Gianloko/apex-coder-1.5b-GGUF:Q4_K_M
|
||||
ollama run hf.co/Gianloko/apex-coder-1.5b-GGUF:Q4_K_M
|
||||
```
|
||||
|
||||
## 🔧 LoRA adapter
|
||||
|
||||
If you already have the base model loaded, use the
|
||||
[LoRA adapter](Gianloko/apex-coder-1.5b-lora) (~150 MB) instead:
|
||||
|
||||
```python
|
||||
from peft import PeftModel
|
||||
model = PeftModel.from_pretrained(base_model, "Gianloko/apex-coder-1.5b-lora")
|
||||
```
|
||||
|
||||
## ⚙️ V6 pipeline notes
|
||||
|
||||
- **Warm-start training** — cycle 2+ initialises from previous LoRA adapter
|
||||
- **Best-ever gate** — publish blocked if new model regresses vs published model
|
||||
- **Data quality** — validated with langdetect + non-ASCII ratio filter
|
||||
- **CanaryCallback** — 3 probes per epoch, majority-fail aborts training
|
||||
- **Post-merge validation** — 3 sanity + 3 hallucination probes gate every push
|
||||
- **Dataset versioned** — cycle tags on HuggingFace for full rollback capability
