KALYPSO v1.1L is the public coding model of the KALYPSO family by GENOMA Labs. It is Qwen2.5-Coder-14B-Instruct fine-tuned with LoRA (r=64, alpha=128, merged to full fp16 weights) on Kraken-Public, a decontaminated dataset of 18,049 records derived from NVIDIA Nemotron coding data.

It is tuned for agentic coding: multi-step programming tasks, tool-calling scaffolds, and plan-then-implement workflows in Python, C++, and SQL.

Benchmarks (EvalPlus)

Benchmark	KALYPSO v1.1L	Qwen2.5-Coder-14B-Instruct (ref)
HumanEval	87.8	~89
HumanEval+	82.9	~87.2
MBPP	84.7	~84
MBPP+	70.4	~72.8

Honest framing: pure code completion is saturated at the 14B scale, and this model scores at parity with its base. v1.1L is published as the reference fine-tune for the Kraken-Public dataset; its value is agentic breadth, not single-shot completion wins.

Usage

vLLM (recommended for serving):

vllm serve genomalabs/KALYPSO-v1.1L --dtype float16 --max-model-len 32768

Transformers:

python

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "genomalabs/KALYPSO-v1.1L"
tok = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype="float16", device_map="auto")

messages = [{"role": "user", "content": "Write a Python function that merges overlapping intervals."}]
inputs = tok.apply_chat_template(messages, add_generation_prompt=True, return_tensors="pt").to(model.device)
out = model.generate(inputs, max_new_tokens=512)
print(tok.decode(out[0][inputs.shape[-1]:], skip_special_tokens=True))

Uses the standard Qwen2.5 chat template. Context length: 32k.
