Sie vs Temporal AI
Side-by-side comparison of features, pricing, and ratings
Sie or Temporal AI: which should you choose?
| Dimension | Sie | Temporal AI |
|---|---|---|
| What it is | Self-hosted Kubernetes inference cluster for specialist models | Durable execution platform for long-running workflows and AI agents |
| Languages / SDKs | OpenAI v1-compatible HTTP endpoint, any client language | Go, Java, Python, TypeScript, .NET, PHP, Ruby, Rust |
| Core capability | Dense/sparse/multi-vector embeddings, reranking, OCR, extraction | State capture per Workflow step, replay, Signals, Queries, Updates |
| Deployment | EKS, GKE, AKS, or air-gapped, Helm/Terraform/KEDA autoscale | Open source MIT or Temporal Cloud (new Azure pre-release) |
| Best fit | Teams with GPUs and Kubernetes paying per-token for inference | Teams whose multi-step executions must survive crashes and abandoned sessions |
These are not alternatives, so the only real question is whether you need one, the other, or both. If your problem is executions that must survive worker crashes, retries, and sessions abandoned mid-flight, pick Temporal — its durable state, replay, and compensating-transaction Saga pattern address exactly that failure class, and Temporal Cloud on Azure plus Serverless Workers for Lambda and Cloud Run are new delivery options. If your problem is inference cost and data residency for embeddings, rerankers, OCR, and extraction, pick Sie, provided you already run Kubernetes and GPUs. A RAG or agent team at scale will plausibly run Sie for the model tier and Temporal for the orchestration tier — they sit at different layers of the same stack, not in the same slot.
SIE serves small open models for embeddings, reranking, OCR, and extraction on your GPUs or its API

Durable execution platform that keeps AI agents and long-running workflows alive through crashes, retries, and abandoned sessions.
Visit WebsiteWho should pick Sie, and who should pick Temporal AI?
- Platform engineer running multi-step microservicesPick: Temporal AI
Activities retry with backoff and heartbeat, state is captured per step, and Saga compensation rolls a failed step back — all without hand-rolling a state machine.
- AI agent team with sessions users abandonPick: Temporal AI
Workflow state persists, so an abandoned or crashed run resumes mid-flight, and Signals and Updates let you steer it while it runs.
- RAG engineer at steady inference volumePick: Sie
Cluster-wide queue batching benchmarks at 89% GPU efficiency and LRU eviction shares GPUs across models, beating per-token embedding and rerank bills at sustained load.
- Document processing pipeline ownerPick: Sie
OCR to markdown, entity/relation extraction, and schema-valid JSON extraction ship as one deployment on your own cluster.
- Regulated team with data-residency rulesPick: Sie
Prompts and documents never leave your cloud on an air-gapped EKS, GKE, or AKS cluster under Apache 2.0 with SOC2 Type 2.
Frequently Asked Questions
Sie vs Temporal AI: which should you choose?
These are not alternatives, so the only real question is whether you need one, the other, or both. If your problem is executions that must survive worker crashes, retries, and sessions abandoned mid-flight, pick Temporal — its durable state, replay, and compensating-transaction Saga pattern address exactly that failure class, and Temporal Cloud on Azure plus Serverless Workers for Lambda and Cloud Run are new delivery options. If your problem is inference cost and data residency for embeddings, rerankers, OCR, and extraction, pick Sie, provided you already run Kubernetes and GPUs. A RAG or agent team at scale will plausibly run Sie for the model tier and Temporal for the orchestration tier — they sit at different layers of the same stack, not in the same slot.
Do I have to choose between Temporal and Sie?
No — and most large teams shouldn't. Sie handles the model-serving layer (embeddings, reranking, OCR, extraction) and Temporal handles the execution layer (durable state, retries, replay). A RAG or agent pipeline heavy enough to want both can use Sie as the inference tier and Temporal as the orchestration tier.
What does Sie cost if I self-host instead of joining the Managed Sie waitlist?
The self-hosted project is Apache 2.0 and free of license fees; your cost is GPU capacity plus Kubernetes engineering. Superlinked's own comparisons concede Modal for bursty compute and Sie for sustained inference, so run the math on your duty cycle before committing hardware.
Can Sie orchestrate my agent, or does it only serve models?
It runs an agent loop with streaming open LLMs via an OpenAI v1-compatible endpoint, so a simple loop is possible in-cluster. What it does not provide is durable execution — no replay, no per-step state capture, no Signals, Queries, or Updates on a running execution.
Will Temporal host my models or run my inference?
No. Temporal runs LLM and tool calls as Activities, meaning each call is dispatched, retried, and timed out with durability guarantees — the model executes elsewhere, whether that's a hosted API or your own cluster.
Is Temporal Cloud available outside AWS?
Yes, expanding. Temporal Cloud on Azure is in an invite-only pre-release as of June 1, 2026. Projects (organizing namespaces and Nexus endpoints) and Custom Roles are also in pre-release, and Serverless Workers are in public preview for AWS Lambda with GCP Cloud Run in pre-release.
Can a small team with no Kubernetes experience adopt Sie?
Realistically no. Sie explicitly excludes teams without Kubernetes or GPU-infrastructure experience and no appetite to hire it. Hot reload, KEDA autoscale from zero, and multi-backend serving (SGLang, vLLM, TensorRT-LLM, TEI, PyTorch, Candle) are operator features, not no-ops.
Which Temporal workloads should stay off Temporal?
Simple cron jobs where durability never gets exercised, stateless request/response APIs with no long-running state, and latency-critical synchronous paths where the Workflow model adds overhead. Temporal's own guidance also flags deterministic Workflow code as a requirement — no random calls, no direct clock reads.
What else are Sie and Temporal AI compared with?
These are not substitutes, so there is no either/or decision here. If your pain is "something broke in production and I need errors, traces, logs, replay, and an AI agent to explain and patch it," buy
