OpenAI Realtime API vs Procore AI

Pay-as-you-go. Audio input $0.06/min, audio output $0.24/min (as of 2025). Text within realtime sessions at standard GPT-4o rates. No free tier.

Enterprise licensing. Annual contract pricing based on construction volume. No public pricing. Publicly traded company (PCOR). 14-day trial available.

Audio data processed on OpenAI's servers. By default, audio is not used for training. Review OpenAI's API data handling policy for sensitive voice applications.

Review Procore's data handling policy. Construction project drawings, safety data, and financial information processed on Procore's infrastructure under enterprise data handling agreements.

• ✓Native audio processing preserves emotional cues and prosody lost in STT-text-TTS pipelines
• ✓Sub-second latency enables natural conversational AI experiences matching human conversation speed
• ✓Same technology powering ChatGPT Advanced Voice Mode provides validated quality benchmark
• ✓Function calling in voice enables voice AI agents that complete tasks rather than only answering questions

• ✓16,000+ customers including Turner, Skanska, and Mortenson validate at large general contractor scale
• ✓Drawing conflict detection addresses one of the most expensive sources of construction cost overruns
• ✓Safety AI applies data science to the domain where human review of all safety data is impractical
• ✓AI on Procore data is immediately valuable as the platform already holds all project documentation

• ✕$0.24/min audio output pricing accumulates quickly for high-volume voice applications
• ✕WebSocket architecture requires different implementation approach than standard REST API calls
• ✕Limited to GPT-4o — no model flexibility for latency vs cost trade-offs

• ✕Enterprise-only pricing appropriate only for large general contractors and project owners
• ✕AI features are add-ons to an already significant Procore subscription cost
• ✕Construction is a conservative industry — AI adoption requires change management alongside the technology
