Instructions to use EssentialAI/rnj-1-instruct with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use EssentialAI/rnj-1-instruct with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="EssentialAI/rnj-1-instruct")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("EssentialAI/rnj-1-instruct")
model = AutoModelForCausalLM.from_pretrained("EssentialAI/rnj-1-instruct")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

vLLM

How to use EssentialAI/rnj-1-instruct with vLLM:

Install from pip and serve model

# Install vLLM from pip:
pip install vllm
# Start the vLLM server:
vllm serve "EssentialAI/rnj-1-instruct"
# Call the server using curl (OpenAI-compatible API):
curl -X POST "http://localhost:8000/v1/chat/completions" \
	-H "Content-Type: application/json" \
	--data '{
		"model": "EssentialAI/rnj-1-instruct",
		"messages": [
			{
				"role": "user",
				"content": "What is the capital of France?"
			}
		]
	}'

Use Docker

docker model run hf.co/EssentialAI/rnj-1-instruct

SGLang

How to use EssentialAI/rnj-1-instruct with SGLang:

Install from pip and serve model

# Install SGLang from pip:
pip install sglang

gemma3 is absolutely trash.

while this model isn't that, it still uses the same implementation of attention. it's trash for quantization, it's trash for inference, it's trash for any sorta computation beyond take it and inference it on TPUs.
I might be alone in asking for this, but I'd very much appreciate it if you left a dumpster fire like google behind and used a normal implementation that can work with the rest of the libraries instead of fighting with the developer because google's fucking shares might drop. what has google done for us lately?! except sucking our bones dry like the parasite it is?
