Usage
Example loading pattern with Transformers:
from transformers import AutoModelForCausalLM, AutoTokenizer
model_id = "YOUR_ORG/SYNIN-V1.0-PRO"
tokenizer = AutoTokenizer.from_pretrained(
model_id,
trust_remote_code=True
)
model = AutoModelForCausalLM.from_pretrained(
model_id,
trust_remote_code=True,
device_map="auto"
)
Replace YOUR_ORG/SYNIN-V1.0-PRO with the actual Hugging Face repository containing the model.
For large-scale inference, use an inference engine and multi-GPU deployment configuration appropriate for the model architecture.

Model Provenance
Base model:
XiaomiMiMo/MiMo-V2.6-Pro-RL
SYNIN V1.0 PRO is a SYNIN-branded derivative based on the upstream MiMo release.
This repository is maintained independently and does not automatically track future changes made to the upstream repository.
Future SYNIN releases may include additional post-training, optimization, alignment, evaluation, or proprietary model development.
---
Limitations
Like other large language and multimodal models, SYNIN V1.0 PRO may:
Generate incorrect information
Produce inaccurate reasoning
Misinterpret visual or audio inputs
Generate incorrect or insecure code
Reflect limitations in its training data
Produce outputs that require human verification
Applications should implement appropriate validation, monitoring, safety controls, and human oversight.
