AI21 Labs
Fluents + AI21 Labs empowers businesses with AI-driven voice automation. Streamline communication across enterprise systems using advanced orchestration and robust compliance features.
Run AI21 Labs Jamba as Your Fluents Conversation Engine
Fluents uses Google Gemini as its default conversation engine. AI21 Labs' Jamba model is available as an alternative for enterprise customers with existing AI21 agreements or those evaluating the performance of AI21's novel hybrid SSM-Transformer architecture for their specific voice AI use case.
Jamba's architecture combines the long-context efficiency of state space models with the reasoning quality of transformers — potentially offering advantages in processing long intake calls or complex multi-document contexts during conversations.
Jamba's hybrid architecture handles very long context efficiently — useful for complex intake calls that cover a lot of ground before completing
Available for teams with existing AI21 enterprise agreements who want to consolidate their AI model usage under a single vendor relationship
Strong instruction-following supports the structured intake, qualification, and data extraction workflows that Fluents agents run

The Fluents Stack With Jamba
Replacing Gemini with Jamba in Fluents means: Deepgram transcribes the caller's speech, Jamba processes the conversation and generates the agent's response, and ElevenLabs synthesizes that response into voice. The call orchestration, context injection, CRM writing, and Insights output all remain identical — only the LLM reasoning layer changes.
Long Intake Calls: Where Jamba's Architecture Shines
FNOL insurance calls and legal intake calls can run long — 8-15 minutes of back-and-forth before all required information is collected. Jamba's hybrid architecture maintains long context efficiently, meaning the agent retains full recall of everything said earlier in the call without degradation. For organizations where long-context retention is a pain point with other models, Jamba is worth evaluating.
Enterprise Vendor Consolidation
Organizations that have signed enterprise agreements with AI21 Labs for other use cases — document analysis, summarization, classification — can extend that relationship to their Fluents voice AI deployment. Consolidating under a single AI vendor simplifies procurement, compliance review, and data processing agreements.
Calls That Just Work
No per-minute taxes. No brittle workflows. Just enterprise-grade reliability with API-level flexibility.

FAQs
Questions about AI21 Labs in Fluents.
Jamba's hybrid SSM-Transformer architecture is particularly efficient at processing long contexts. For most Fluents use cases, Gemini performs better overall. Jamba becomes relevant when you have very long calls, existing AI21 agreements, or specific benchmarking requirements. Contact the team to discuss.
Alternative LLM configuration is an enterprise feature. Contact the Fluents team to discuss requirements and availability.
No. ElevenLabs handles voice synthesis and Deepgram handles transcription regardless of conversation engine. Your agent configurations and Insights output format are unchanged.
