Answered from the vendors’ own pages

Arize AI: What does Arize AX cost?

Arize AX offers a free plan, a Pro plan at $50/month, and a custom-priced Enterprise plan, with pricing based on trace spans, storage, and retention needs.

Source
Microsoft Power Automate: Is Power Automate included with Microsoft 365?

Yes. If you have an eligible Microsoft 365 subscription, you can use Power Automate at no extra cost for flows relying only on standard connectors (SharePoint, Outlook, Teams). Premium connectors (Salesforce, SAP, Oracle) require paid plans.

Source
Arize AI: Is there a free plan, and what are its limits?

The AX Free plan includes 25,000 trace spans and 1 GB of storage per month with 15-day retention, plus unlimited users, evaluations, and experiments.

Source
Microsoft Power Automate: How many flow runs are allowed on the free plan?

Power Automate's free tier (included with Microsoft 365) is limited to 750 flow runs per month and standard connectors only. Out of 900+ total connectors, the free plan only includes Microsoft ecosystem apps and limited third-party apps.

Source
Arize AI: What deployment options are available?

Free and Pro plans are SaaS-only, while Enterprise customers can choose SaaS or self-hosted deployment with custom SLAs.

Source
Microsoft Power Automate: What's the difference between Premium and Process plans?

Premium ($15/user/month) provides attended automation with cloud flows and standard RPA. Process plan ($150/bot/month) enables unattended automation where bots run without human intervention on virtual machines for high-volume, repetitive tasks.

Source
Microsoft Power Automate: Does Power Automate support long-running workflows?

No. Power Automate is not suitable for long-lasting workflows because they can run without warning and fail unexpectedly. The platform is built for linear, branching logic (if-then) rather than complex, multi-step business processes involving multiple stakeholders.
