If you're building AI agents that must survive crashes or orchestrating multi-step workflows with human oversight, Temporal AI is your best bet — its durable execution and LangGraph Plugin (2026) make failures painless. On the other hand, if you need to run large models like Stable Diffusion on a Raspberry Pi with minimal memory, OnnxStream is the only choice. They solve orthogonal problems: reliability vs. resource efficiency.
Streaming ONNX inference for RAM-constrained edge devices, Raspberry Pi to WASM.

What users praise
- • Runs SDXL in just 298MB RAM – unmatched memory efficiency.
- • Streaming model execution avoids loading full graph into memory.
- • Supports ARM, x86, WASM, and RISC-V architectures.
- • Python, C#, and JavaScript/WASM bindings enable diverse deployment.
What frustrates them
- • Compilation errors on Raspberry Pi 5 and other newer hardware.
- • Converting custom models to ONNX is poorly documented and tricky.
- • No built-in logging – users must implement their own.
- • CPU-only inference is extremely slow for real-time use.

Who should pick which
- AI agent developer needing crash-proof agentsPick: Temporal AI
Temporal's durable execution and LangGraph Plugin (2026) automatically recover agent state on failure, perfect for OpenAI or LangGraph-based agents.
- Embedded engineer running LLMs on Raspberry PiPick: OnnxStream
OnnxStream can run Mistral 7B on a Raspberry Pi Zero 2 with minimal RAM, exactly for memory-constrained edge devices.
- Developer building Saga-based financial systemsPick: Temporal AI
Temporal's compensating transactions and automatic retries implement the Saga pattern natively for rollback on failure.
- Hobbyist wanting browser-only Whisper speech recognitionPick: OnnxStream
OnnxStream's WASM bindings run Whisper fully in-browser without a backend server, demonstrated on the project's demo page.
- Team orchestrating multi-step microservices with human oversightPick: Temporal AI
Human-in-the-loop via signals and pause/resume, plus integrations with Slack and Salesforce, make Temporal ideal for approval workflows.
Frequently Asked Questions
OnnxStream vs Temporal AI: which should you choose?
If you're building AI agents that must survive crashes or orchestrating multi-step workflows with human oversight, Temporal AI is your best bet — its durable execution and LangGraph Plugin (2026) make failures painless. On the other hand, if you need to run large models like Stable Diffusion on a Raspberry Pi with minimal memory, OnnxStream is the only choice. They solve orthogonal problems: reliability vs. resource efficiency.
Can Temporal AI run on edge devices like a Raspberry Pi?
Temporal is designed for server and cloud environments, not for low-memory edge devices. Its Workers require a runtime with SDK support (Python, Go, etc.) and network connectivity to Temporal Server, making it unsuitable for a Raspberry Pi with limited RAM.
Does OnnxStream support GPU acceleration?
OnnxStream uses XNNPACK for CPU acceleration but does not mention GPU support. It is optimized for CPU inference on edge devices, not for GPU-based high-throughput scenarios.
What is the LangGraph Plugin in Temporal?
Announced July 2026, the LangGraph Plugin adds durable execution to LangGraph-based AI agent workflows, ensuring state recovery and reliability for LangGraph agents.
Can I use OnnxStream for production servers?
OnnxStream is designed for resource-constrained devices and may not offer the throughput of GPU-accelerated inference. It's best for edge or browser deployments, not high-performance server use.
Is Temporal AI free for commercial use?
The open-source Temporal Core is free for self-hosting under MIT license. Temporal Cloud is paid on a usage basis. No separate commercial license is required for self-hosted use.
What architectures does OnnxStream support?
OnnxStream supports ARM, x86, WASM, and RISC-V architectures, making it highly portable to embedded systems, desktops, and browsers.
Does Temporal AI have a Rust SDK?
Yes, the Rust SDK was released in public preview in May 2026, enabling Rust developers to build Temporal applications.
Can OnnxStream run models other than ONNX?
OnnxStream is specifically for ONNX models. It uses a text-based representation (onnx2txt converter) to load graphs incrementally, so it only works with ONNX-format models.
