Synoema IoT Rules model — fine-tuned for generating Synoema IoT automation rules that compile and run on bare-metal MCUs, ESP32, STM32, and Linux edge devices.

Synoema is a formally verified, BPE-aligned functional language for LLM-generated software. GBNF grammar + Hindley-Milner types + contracts eliminate the verification gap — prompt to native / WASM / IoT with no human review.

Model Description

Mid-range IoT model (1.5B parameters). Best balance of size and capability. Handles complex multi-condition rules.

This model generates Synoema IoT rules — compact functional programs that:

Compile to WASM artifacts (mean size ~82–292 bytes)
Run on Tier 0 bare-MCU (wasm3), Tier 1 ESP32/STM32, and Tier 2 Linux edge
Express automation logic with formal requires/ensures contracts
Support verticals: Home, Industrial, Wearable, Automotive, Agriculture

Usage (Python / transformers)

python

from transformers import AutoTokenizer, AutoModelForCausalLM
from peft import PeftModel
import torch

base = "Qwen/Qwen2.5-Coder-1.5B-Instruct"
adapter = "delimitter/synoema-iot-lite-1.5b-v1"

tok = AutoTokenizer.from_pretrained(base)
model = AutoModelForCausalLM.from_pretrained(base, torch_dtype=torch.float16, device_map="auto")
model = PeftModel.from_pretrained(model, adapter)

SYS = "You are a Synoema IoT rules expert. Generate only valid Synoema rule code. No explanation."
prompt = tok.apply_chat_template([
    {"role": "system", "content": SYS},
    {"role": "user",   "content": "activate the fan if temperature exceeds 30"},
], tokenize=False, add_generation_prompt=True)

inp = tok(prompt, return_tensors="pt").to(model.device)
out = model.generate(**inp, max_new_tokens=128, do_sample=False)
print(tok.decode(out[0][inp["input_ids"].shape[1]:], skip_special_tokens=True))
