Use the table below to compare each provider’s documented scope.
Before you decide
Bland AI: Per-minute AI rate with separate platform fees on team plans; telephony and transfer minutes are additional; Enterprise is custom. OpenAI Realtime: Token-based API pricing for text, audio, and image modalities; audio input/output rates are published per million tokens. Ask both vendors to quote the same expected workload, required channels, and implementation scope. Include required subscriptions and usage charges before comparing the total; the listed starting prices alone may cover different work.
The recorded knowledge and data sources for Bland AI include documents; runbooks; policy libraries. For OpenAI Realtime, they include Not publicly documented. Ask each provider to demonstrate access for the exact systems you use, with permissions, freshness, and failure behavior. A source missing from this directory is not proof that a provider cannot support it.
Use the same representative calls, approved instructions, and escalation rules in both pilots. How does it handle interruption and uncertainty? Which actions can it complete, and which require approval? What context reaches a human during transfer? Record conversation quality, completed tasks, human handoffs, and total cost in the buyer worksheet. Check these specific cautions before launch: Bland AI: Published pages document knowledge grounding, live API actions, and integrations, but buyers should verify the exact channel, plan, region, and implementation scope in a pilot. Outbound programs require consent, suppression, disclosure, and jurisdiction-specific review. OpenAI Realtime: Not a turnkey contact center. Implement telephony operations, identity, tools, monitoring, evaluation, retention, and escalation.
