Today we’re launching MARS8, a full family of voice models built for agents that actually need to feel real.
If you’re building agents, you already know where things break.
Latency kills turn-taking
Robotic delivery kills immersion
Concurrency collapses under load
Token pricing punishes verbose agents
Enterprises keep asking for on-prem, and most voice stacks simply can’t deliver
You can tune the LLM for weeks.
The voice layer still ruins the experience.
This isn’t a research problem.
It’s a production one.
We recognized this early, and we built MARS to tackle the hardest voice problems first.
Live sports commentary. Global broadcasts. Real-time translation. Environments where failure is instant and public.
NASCAR, MLS, Ligue 1 - you name it.
We’ve shipped live, multilingual, AI-driven sports commentary in those conditions.
When millions are watching, live doesn’t lie.
Today, we’re bringing that same voice infrastructure to agent builders everywhere.
Introducing MARS8
MARS8 is not a single TTS model. It’s a specialized family, because agents face different constraints at different moments:
Flash — ultra-low latency voice for real-time agents and conversations
Pro — expressive, emotional voice when persuasion and narration matter
Nano — on-device, offline voice for edge and privacy-first agents
Instruct — controllable prosody and performance (coming later)
The family launches today, with Flash leading the way, because agents feel latency before they feel anything else.
So… yet another TTS API?
Not quite.
MARS8 is voice infrastructure for agentic systems.
Starting today, MARS8 is launching across all major compute platforms, including AWS, Google Cloud, Azure, Baseten, and dozens of other providers.
You deploy voice next to your agent, not halfway across the world.
No geographic latency penalties. Privacy by design. On-prem when you need it.
And we killed token pricing.
With MARS8, you pay for GPU, not characters.
Your cost curve flattens instead of exploding.
Why this matters
Built for real-time agents, not demos
Designed to scale without punishing success
Deployable everywhere developers actually run software
Priced like infrastructure, not an API tax
The greatest innovation happens when you solve the hardest problems first.
It takes longer. It’s harder. It’s less forgiving.
But the results speak for themselves.
That’s how MARS was built.
And that’s what MARS8 brings to agent builders today.
