Session vs Deepgram

Side-by-side trajectory, velocity, and editorial themes.

Session shipped a protocol rewrite and a paid tier, then went publicly broke — the founder is asking users to bail it out.

◆ Current state

Session is simultaneously in its most ambitious technical phase and an open funding crisis. Protocol V2 — re-implementing forward secrecy and layering post-quantum cryptography on top of Session's onion-routed transport — has been announced, and the Session Pro paid tier exited beta planning into a December development update. Then in March, cofounder Chris McCabe published a personal appeal saying the project cannot continue developing without user support, and the public feed has been quiet since.

◆ Where it's heading

The product roadmap that was meant to fund itself via Session Pro is colliding with the underlying problem the appeal makes plain: the Loki/Oxen-era token economics and donations aren't covering ongoing development. Protocol V2 and Pro are the bets that have to land for Session to remain viable; if Pro doesn't convert a meaningful share of the user base, the next twelve months are about scope reduction, not feature growth. The Feb 1 APT key rotation in January suggests the core infrastructure is still being maintained — for now.

◆ Prediction

Watch for either a hard Session Pro launch and conversion announcement, or a more explicit wind-down / handoff post. A long stretch of silence after a funding appeal usually resolves one way or the other within a quarter; the absence of any new posts since mid-March is itself a signal.

D6.3

Diarization v2 lands with a 3.3× human-eval edge — Deepgram's contact-center push gets sharper.

◆ Current state

Deepgram is shipping in two coordinated lanes: deeper transcription quality (Nova-3 multilingual numerals, Gujarati, profanity filtering across 50+ languages) and a maturing Voice Agent API (managed LLM swaps, third-party TTS controls). The new opt-in diarize_model=v2 brings a new architecture preferred 3.3× over v1 in human eval, with the biggest gains on contact-center audio. Self-hosted images and multi-language SDKs are released on a tight, predictable cadence.

◆ Where it's heading

The arc is consolidating around enterprise contact-center workloads: better speaker separation, safer outputs via profanity redaction, and richer language coverage are exactly the gates that block call-center adoption. Voice Agent is becoming a managed-LLM thin layer where customers pick the brain (OpenAI, removed Llama Nemotron) while Deepgram owns ears and mouth. Expect diarize_model=v2 to become the default once telemetry catches up.

◆ Prediction

Likely next: v2 diarization promoted to default for diarize=true, and a streaming version of the same architecture to extend the contact-center story to live transcription. More managed-LLM additions in Voice Agent, plus continued language fill-in for Nova-3.
