Pros	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	Open-source weights under Apache 2.0 for the CSM speech model Distinctly natural, context-aware prosody compared to typical TTS Backed by serious original research with published benchmarks Free research preview available at app.sesame.com
Cons	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	No public commercial API - you self-host the open weights Pricing and productisation still vague; consumer app is invite-only Hardware (AI glasses) not shipping until 2027 Small model catalogue focused on English voice quality
