Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

PromptLayer

The free plan is capped at only 2,500 requests per month, quite limited for active production use.
The Team plan jumps to $500/month, a large step up from the $49/month Pro plan.
Overage transaction fees apply on top of subscription costs, which can make total spend less predictable.
Enterprise-grade features like HIPAA BAAs and custom deployment require contacting sales.

Pulumi

The free Individual plan allows one user and one concurrent stack update
The Team plan is $40 per month base including 40 credits, and caps the organisation at 10 users
SAML/SSO, RBAC, audit logs and drift detection require the Enterprise plan at $400 per month base
The per-resource rate rises from $0.1825 per resource per month on Team to $0.365 on Enterprise, so upgrading raises the unit price as well as the base fee
Managed secrets are billed separately at $0.50 per secret per month on Team and $0.75 on Enterprise
Self-hosting, SCIM user sync, audit log export and 24x7 support are only in Business Critical, which is custom priced with no published rate
Team includes up to 500 resources and Enterprise up to 2,000, with everything beyond billed on demand as credits
