Pros	High accuracy Strong streaming API Lots of post-processing features Excellent SDKs and docs	Sub-400ms voice latency keeps conversations feeling natural rather than turn-based Models can run on customer infrastructure, unlocking healthcare, financial services, and other regulated use cases Unified agent context across voice, SMS, iMessage, and web chat rather than siloed channels Scenario-based testing lets you regression-test agents against simulated calls before production Strong contact-center integration coverage (Twilio, Salesforce, HubSpot, Genesys, Five9, Zapier) 40+ language support with real-time translation across 23 Norm assistant lowers the barrier for non-specialists to build production agents
Cons	More expensive than Whisper for high volume Latency varies	Pricing is not transparent; per-minute rate and enterprise tiers require contact-sales Underlying model family is proprietary and undocumented, limiting portability and evaluation Enterprise positioning and self-hosted deployment options are overkill for hobbyists or small pilots No open-source components; you are locked into Bland's platform for orchestration and telephony glue Public documentation of hard limits (concurrent calls, rate limits, latency guarantees) is thin outside of sales conversations
