SDK

Open-source SDKs

One unified developer surface for TsugiCinema's distributed-training SDKs. 

pip install tsugi

TsugiLabs is the research division of TsugiCinema, Inc., a Delaware C-corporation (2026). NVIDIA Inception member.

Two engines

The tsugi meta-package wraps two physically separate SDKs under a unified import namespace. The two engines share zero code and can be installed and used independently.

PyPI · imports as tsugi.mend
tsugi-mend

Cross-rack distributed-training resilience: straggler and fail-slow detection with concurrent recovery. Patent-independent by construction. The default mode is bit-exact against tsugi-mend's own synchronous reference path. Throughput is benchmarked against FSDP baselines. 

from tsugi.mend import MendConfig, mend_init, mend_shutdown

# After your model is wrapped (FSDP, TP, etc.):
config = MendConfig(quorum_min_learners=2, grace_window_ms=2000)
mend_init(model, config)

# ... train ...

mend_shutdown(model)
PyPI · imports as tsugi.kpool
tsugi-kpool

K-of-N LoRA continual learning without replay buffers. Practices US App. 64/060,315 and 64/055,093 as distributed. 

from tsugi.kpool import KPoolLoraConfig, plesio_init, plesio_shutdown

config = KPoolLoraConfig(
    r=16,
    lora_alpha=32,
    n_adapters=8,
    k_active=4,
    sideband_enabled=True,
    aggregation_mode="buffer_convergence",
)
plesio_init(model, config)

# ... train with K-of-N adapter routing ...

plesio_shutdown(model)

Benchmark campaign

A pre-registered H100-over-InfiniBand stall-recovery benchmark campaign is prepared. The pre-registration (hypotheses, arms, analysis plan) publishes openly in the tsugi-mend repository on the day the venue is booked, and results publish openly regardless of outcome.
