Choose by what you need to scale. Exo is aimed at pooling devices for distributed inference; GPUStack manages GPU clusters and model-serving services, with documented multi-node inference backends; LocalAI offers both request routing to worker nodes and a separate mode that shards compatible models across workers. These are different approaches, not interchangeable versions of the same orchestrator.
First decide what “across multiple computers” means
A multi-node LLM setup can solve two different problems:
- Serve more requests: run model instances on workers and route incoming requests among them. This can increase capacity for concurrent users, but does not necessarily split one model’s inference across machines.
- Run one model across devices: divide a model’s inference work among devices or nodes. This can make a model run across available compute that would not be used as one independent replica, but depends on the model, backend, hardware, and interconnect.
LocalAI explicitly documents both patterns. GPUStack focuses on managing clusters and inference services, while also documenting particular distributed-inference paths. Exo describes connecting devices for distributed inference. Identify the workload first: the right choice for serving more requests may not be the right one for splitting a single model.

| Project | What it is for | Multi-node approach described in its documentation | Important constraint |
|---|---|---|---|
| Exo | Pooling devices into an AI cluster for distributed inference | Automatic device discovery and topology-aware parallelization; its README describes tensor parallelism, MLX, MLX distributed communication, and RDMA over Thunderbolt 5. | Device and network topology matter.

| GPUStack | Managing GPU clusters and deploying inference services | A server-side control plane manages workers and model services; documentation describes distributed inference paths using vLLM, SGLang, and MindIE, including Ray bootstrapping for distributed vLLM. | Backend support does not guarantee that every model, accelerator, or release configuration works. Check the exact support matrix and deployment path. |
| LocalAI | Serving models through distributed infrastructure, or experimenting with peer-to-peer inference | Its production-oriented distributed mode routes work among worker nodes. Its separate P2P worker mode can shard a compatible model across workers. | P2P model sharding is limited to llama.cpp-compatible models. Production distributed mode requires authentication, PostgreSQL, and NATS coordination. |

When Exo is the better fit
Consider Exo when your goal is to connect devices and distribute inference across them, and its supported device and communication paths match your setup. The project describes automatic device discovery and topology-aware auto-parallelization, along with MLX-based inference and distributed communication. It also describes RDMA over Thunderbolt 5.
For Exo, networking is part of the architecture—not an afterthought. A setup’s behavior depends on the connected devices and their communication path. The README’s performance claims, including latency and tensor-parallel results, are claims from the Exo project; they should not be treated as guarantees or as a head-to-head result against GPUStack or LocalAI. A fair performance comparison would need the same model, quantization, prompt and context, concurrency, hardware, and network conditions.

When GPUStack is the better fit
GPUStack is the most management-oriented option in this group. Its documentation describes a server with an API server, scheduler, and controllers; workers with runtime, serving management, and metrics; and an AI gateway for routing and load balancing. It also describes monitoring, access control, and management across on-premises environments, Kubernetes, and cloud providers.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
That control plane is useful when the problem includes managing workers and model services, not just running inference across devices. GPUStack documents model rollout and scaling controllers, and says it can bootstrap a Ray cluster on demand for distributed vLLM across multiple workers. Its FAQ lists multi-node, multi-GPU support for vLLM, SGLang, and MindIE. Treat these as documented paths to verify against your exact release, hardware, model, and inference-engine configuration—not as a claim that any combination is supported.

Distributed mode for worker-based serving
LocalAI’s distributed mode is aimed at production deployments, including Kubernetes environments. Its documented architecture uses stateless frontends, a SmartRouter, worker nodes, PostgreSQL-backed state and registry, and NATS for coordination. Authentication must be enabled, and SQLite is not supported for distributed state.

- Model staging: without shared-model mode, model snapshots are staged to workers. Account for disk space for copies on each controller and worker.
- Worker transfers: the documentation warns that an empty registration token can leave worker file transfer unauthenticated. Include authentication and reachable network paths in the deployment design.
P2P mode for experimentation and model sharding
LocalAI’s P2P page describes ad-hoc clusters, community sharing, and experimentation. In federated mode, a whole request is routed to a selected worker; in worker mode, multiple workers share model weights and contribute to one inference. The latter is exclusive to llama.cpp-compatible models, and the documentation characterizes P2P federated mode as experimental or tech-preview quality. Do not assume P2P worker sharding is a general-purpose way to distribute every LocalAI model.

Choose by workload, infrastructure, and operations
| Question | What to look for | How these projects map to it |
|---|---|---|
| Do you need more concurrent requests or one model split across nodes? | Separate replica-based serving from model sharding before choosing. | LocalAI distinguishes federated routing from worker sharding; Exo describes distributed inference; GPUStack documents service management and specific distributed backends. |
| Do you need a centralized control plane? | Consider worker management, scheduling, routing, rollout, and monitoring. | GPUStack describes a server, scheduler, controllers, workers, and gateway. LocalAI distributed mode describes frontends, PostgreSQL, and NATS. Exo advertises automatic device discovery. |
| Which model formats and inference engines must work? | Verify the exact runtime and backend path, not just a project’s general model-serving support. | LocalAI P2P sharding is limited to llama.cpp-compatible models; GPUStack documents named distributed backends; Exo describes MLX and MLX distributed support. |
| Will your devices and network work together? | Check accelerator, operating-system, memory, and interconnect requirements for the chosen release. | GPUStack publishes an accelerator support matrix; Exo describes Thunderbolt 5 networking support. Neither fact alone establishes compatibility for a particular fleet. |
| Can you meet the operational prerequisites? | Plan for state, authentication, model distribution, storage, network reachability, and observability. | LocalAI documents PostgreSQL, NATS, authentication, and model staging for distributed mode. GPUStack describes monitoring and access control. |
| Is one option faster or cheaper? | Compare under a controlled workload on the hardware and network you will use. | The documentation reviewed does not establish a common, independently verified benchmark across all three projects. |
A practical selection path
- Write down the scaling target. If the goal is more simultaneous requests, evaluate worker-based serving and routing. If one model must span devices, confirm that the project supports the needed model and parallelization path.
- Match your control-plane needs. Favor GPUStack when centralized GPU-cluster and model-service management is a core requirement. Consider LocalAI distributed mode when its frontend, router, and worker architecture fits. Consider Exo when connecting devices for distributed inference is the central goal.
- Check exact compatibility. Confirm the release, model format, inference backend, accelerators, operating systems, and interconnect together. A feature listed for one backend or device type does not establish support for another combination.
- Design operations before rollout. Plan authentication, database and coordination services where required, model-file placement or staging, worker storage, reachable network paths, monitoring, and recovery behavior.
- Benchmark your own workload. Use the same model and quantization, prompt and context, concurrency, hardware, and network for each candidate. Record throughput and latency separately; a result for one setup is not a general ranking.
What the documentation does not establish
The reviewed official project pages do not provide a common, independently verified test showing which of these projects is fastest or cheapest. Project feature pages can help identify candidate architectures, but their claims are not comparable unless the underlying conditions match. Hardware compatibility and distributed-backend availability are also release- and configuration-sensitive, so validate those details before committing to a deployment.
