Who should pick which

  • Solo founder building an AI agent
    Pick: Temporal AI

    Temporal provides durable execution, retries, and human-in-the-loop – essential for reliable AI agents. HPT is just a model, not a platform.

  • Mobile app developer needing on-device VQA
    Pick: HPT

    HPT 1.5 Edge (4B) is optimized for edge devices, free, and open-source. Temporal doesn't provide models.

  • Enterprise orchestrating microservices with rollbacks
    Pick: Temporal AI

    Temporal's Saga pattern and workflow state capture are ideal for compensating transactions.

  • Researcher comparing multimodal LLMs
    Pick: HPT

    HPT offers open weights on Hugging Face for benchmarking. Temporal is irrelevant for model comparison.

  • Team integrating Slack with AI workflows
    Pick: Temporal AI

    Temporal has native Slack integration. HPT lacks any integration.

Frequently Asked Questions

HPT vs Temporal AI: which should you choose?

Choose Temporal AI if you need reliable orchestration for AI agents or multi-step workflows with automatic retries and visibility. Choose HPT if you need a free, open-source multimodal LLM that runs locally on edge devices or cloud. They solve different problems: Temporal is a durable execution platform, HPT is a model family.

Can I use HPT with Temporal?

Yes, you could wrap HPT inference as a Temporal Activity to build a durable AI pipeline, but they are independent.

Does Temporal have a free tier?

Yes, self-hosted Temporal Server is free and open-source. Temporal Cloud has a free tier with limited actions.

Is HPT available as an API?

No, HPT is only available as open-source models on Hugging Face. You must self-host.

Which Temporal SDKs are available?

Python, Go, TypeScript, Ruby, C#, Java, PHP, and Rust (public preview).

What hardware do I need for HPT 1.5 Edge?

Designed for edge devices; can run on mobile phones with minimal GPU.

Does Temporal support human-in-the-loop?

Yes, via signals and pause/resume.

Can HPT generate images?

No, HPT is multimodal understanding only. HyperGAI researches generative models but not in HPT.

What's new in Temporal's latest news?

Usage-based billing for cost transparency, custom roles in pre-release, and billable action metric.
