Xlstm
NXAI builds xLSTM memory architectures for edge and industrial time-series work, shipping TiRex-1 and TiRex-2 models on Hugging Face and GitHub.
Choose NXAI and xLSTM when your constraint is state-tracking or edge inference on time-series data and you have in-house ML depth to run TiRex-1 or TiRex-2 from the published Hugging Face weights and GitHub code. The scope is deliberately narrow — univariate and multivariate time series — and the site frames robotics and large-scale world models as tomorrow's work, not today's. If you need a managed forecasting platform with a dashboard and onboarding, take the managed route instead. If you want a general-purpose hosted LLM, this is the wrong shelf entirely. Treat an NXAI engagement as a research partnership, and budget for owning your own integration and edge validation.

Skip NXAI if you need a ready-to-run forecasting API or a managed platform with a dashboard, rather than open model weights you integrate and deploy yourself.
The weights are free but the integration isn't — you fund the engineering time to serve, monitor, and update TiRex-1 or TiRex-2 yourself.

What is Xlstm?
Xlstm — NXAI builds xLSTM memory architectures for edge and industrial time-series work, shipping TiRex-1 and TiRex-2 models on Hugging Face and GitHub. Best for Industrial time-series teams needing edge-deployable models, Edge AI engineers optimizing latency and compute, ML research groups exploring Transformer alternatives. Pricing is on request (custom quotes).
NXAI is a frontier AI lab based in Linz, Austria, building AI on its proprietary xLSTM (Extended Long Short-Term Memory) architecture — a modernization of the classic LSTM with sophisticated memory hierarchies, designed for long-range state-tracking. The company's Chief Scientist and co-founder is Prof. Dr. Sepp Hochreiter, one of the fathers of modern deep learning, and it works closely with JKU Linz and other research institutions. The shipped products are narrow and specific: TiRex-1 handles univariate time-series analysis and TiRex-2 handles multivariate time-series analysis, aimed at industrial edge, embedded, and forecasting deployments where the company states its models deliver 50× impact. NXAI runs its xLSTM models in a cloud environment but focuses on edge applications, using an in-house edge lab to validate real-world deployment. Model weights are published on Hugging Face and source code on GitHub, so teams work directly from the models rather than through a packaged product. The stated roadmap points to large-scale world models built on neural memory hierarchies and memory routing, with robotics as the primary application — described on the site as future work, not shipped product. This is a research-lab relationship model: you bring ML engineering depth, and NXAI brings the architecture. It suits engineering and research groups optimizing for state-tracking efficiency and edge inference; it is a poor fit if you want a hosted, plug-and-play forecasting API.

Behind the verdict
NXAI is unusual in the 2026 AI vendor landscape because it is selling an architecture rather than a subscription. The core claim — that xLSTM's memory hierarchies outperform Transformer baselines on state-tracking — is the whole product thesis, and everything shipped follows from it. What you actually get today is two time-series models. TiRex-1 covers univariate series; TiRex-2 covers multivariate series. Both are published as open weights on Hugging Face with code on GitHub, which means the integration, serving layer, monitoring, and edge packaging are yours to build. That is a real strength for teams who want to inspect and modify the model, and a real cost for teams who don't. The deployment story is the most differentiated part. NXAI runs xLSTM in the cloud but explicitly focuses on edge and embedded applications, backed by an in-house edge lab used to validate real-world deployment. For industrial settings where a cloud round-trip is too slow or connectivity is unreliable, that focus matters more than benchmark placement. The company also cites top positions on globally recognized leaderboards, and its research lineage is legitimate: Sepp Hochreiter as Chief Scientist and co-founder, with close JKU Linz ties, is about as strong a research credential as this category offers. Where it does not fit: the delivered scope. Time series, univariate and multivariate, is what ships. Robotics state-tracking and neural-memory world models are described as the next phase. If your use case sits outside time series today, you are buying a roadmap, not a product. The published-material-only model also means no managed dashboard to evaluate, no packaged onboarding flow, and no plug-and-play API you can test this afternoon — you evaluate the models on Hugging Face or you talk to the lab. For organizations without deep learning engineers on staff, that gap is decisive. For research groups and edge AI teams who already speak the language, it removes a layer of abstraction between them and the architecture.
Models under the hood
as of 2026-11-03
Limitations
- The shipped products are narrow.
- TiRex-1 covers univariate time-series and TiRex-2 covers multivariate time-series; robotics and large-scale world models are described on the site as future work.
- Model weights come from Hugging Face and code from GitHub, so you own the integration, serving, and edge packaging work.
- Deployment spans cloud and — with the stated edge and embedded focus — requires edge-lab-validated integration effort.
- The company's own material does not detail a managed dashboard or packaged onboarding flow.
- If your problem is outside time-series state-tracking, the delivered product likely does not cover it yet.

GeneratedReal-world workflow fit
Concrete scenarios for the personas Xlstm actually fits — and what changes day-one when you adopt it.
Pull TiRex-1 weights from Hugging Face, benchmark them against the existing Transformer forecasting model on a month of plant sensor data, then containerize the winner for a gateway device.
Outcome: A concrete latency-and-accuracy comparison on your own data before any commercial conversation with NXAI.
Clone the GitHub code for xLSTM and run an ablation on long-range state-tracking against a Transformer baseline, using TiRex-2 for a multivariate sensor dataset.
Outcome: A reproducible internal benchmark, plus a documented basis for deciding whether to contact the lab about a deeper collaboration.
Stand up a TiRex-1 forecast for load or demand series in a staging environment, compare inference cost per prediction against the current cloud model, and assess whether edge placement is feasible.
Outcome: A cost-per-forecast number and a go/no-go on edge placement, before committing engineering headcount.
Use cases
- Run industrial anomaly detection on edge devices with xLSTM models instead of Transformer baselines.
- Forecast univariate time-series with TiRex-1 for efficiency-critical deployments.
- Model multivariate sensor and process data with TiRex-2.
- Prototype long-context sequence modeling outside Transformers for research.
- Embed forecasting models on constrained hardware where cloud round-trips are too slow.
- Build robotics state-tracking and control models on xLSTM memory hierarchies as the roadmap matures.
Setup time & first value
How long it actually takes to get something useful out of Xlstm — broken out by persona, not the marketing-page minute.
For an ML engineer comfortable with Hugging Face and PyTorch-style workflows: hours to pull TiRex-1 or TiRex-2 and run a first inference. Days to a working benchmark on your own data. Weeks to production edge deployment, because hardware validation, serving, and monitoring are yours to build. Teams without in-house deep learning staff should expect substantially longer.
Switching to or from Xlstm
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a Transformer forecasting baseline: retrain or fine-tune TiRex-1 or TiRex-2 on your series and benchmark inference latency on the same hardware envelope before switching.
- →From a managed cloud forecasting API: keep the API in place while you stand up the open-weights model locally, then shift workloads once edge latency is measured.
- →From a classical time-series library (ARIMA, ETS): keep the statistical model as a baseline, since it costs nothing to run alongside and gives you a sanity check on xLSTM outputs.
- ↗To a managed forecasting platform: export your training data and re-onboard to the platform's API, accepting less control over the model internals.
- ↗To a Transformer-based time-series model: retrain on the same series and re-tune the serving stack, since the inference characteristics differ.
