SIMCOAI Cura 1
Routine care at the lowest model cost.
Best for frequently asked questions, opening hours, order updates and taking messages at high volume.
The models that answer your phone, by name.
Every SIMCOAI model is a configuration SIMCOAI builds and runs: its own instructions, its own context routing, its own deadlines, its own guardrails. That is what you choose between, and it is the part we control - so the engine underneath can change without changing what you picked or how it behaves.
Answering
SIMCOAI models
Which one answers depends on your plan and on what is being asked. On a live call speed wins, because a caller left in silence hangs up; on a policy question depth wins.
SIMCOAI Sermo 1
Conversation tuned for quick replies.
Best for live phone calls, short chats and first responses where the caller is waiting.
SIMCOAI Mens 1
A steady choice for everyday work.
Best for chat, the dashboard assistant and everyday tasks that benefit from a fuller answer.
SIMCOAI Vis 1.1
Our most capable current model for complex requests.
SIMCOAI Vis 1.1 is our most capable current model, built for detailed policy questions, complex refunds, setup advice and multi-step work. Uses premium allowance.
SIMCOAI Hermes 1
A smaller model for direct voice conversations.
Experimental speech-to-speech calling using the Mini model.
SIMCOAI Athena 1
Speech straight to speech, with no transcription step in between.
Experimental Full speech-to-speech calling. The model hears and speaks directly; response speed is being validated.
Speaking

SIMCOAI speech

SIMCOAI Auditus Certus 1.5
Current-generation transcription for customer names, addresses, reference numbers and browser enquiries.

Straight answers
What this does and does not mean
These are our names, and we say so
SIMCOAI builds on frontier models from established providers and adds its own instructions, routing, limits and safeguards on top. The names above describe what SIMCOAI configured and runs, not a claim to have trained a model from scratch.
Every provider SIMCOAI relies on is named in full in our privacy policy and GDPR and DPA page, because naming who processes your data is a legal requirement rather than a choice.
Why the engine underneath can change
Models improve, prices move and providers have outages. Naming the configuration rather than the engine is what lets us move to a better one without you having to re-choose anything or re-learn what you bought.
Where a change would alter how your service behaves, it goes on our updates page, and anything affecting availability goes on the status page.
Questions
About SIMCOAI's models, voices and speech
Is a SIMCOAI model the same thing as the AI provider behind it?
No. Every SIMCOAI model is a configuration SIMCOAI builds and runs on top of a frontier model from an established provider - its own instructions, context routing, deadlines and guardrails. That configuration is what you choose between and what SIMCOAI controls; it is not a claim to have trained a model from scratch.
Which model answers my phone by default?
SIMCOAI Sermo 1 handles the reply. SIMCOAI Vox Clara 1.5 provides responsive browser speech and speech on compatible live lines. Other live lines retain their supported version-1 voice. Call Studio shows the model available on your current call setup.
What changed in SIMCOAI Voices and Speech 1.5?
SIMCOAI Vox Clara 1.5 provides responsive speech and Vox Magna 1.5 provides richer delivery. Auditus 1.5 uses current-generation speech recognition. Prices are spoken as pounds and pence, with clearer pronunciation of SIMCOAI, AI and common service words. Version 1.5 voice profiles are available for browser speech and compatible live lines; Call Studio shows your active options.
Can I choose which model or voice SIMCOAI uses?
Your plan decides which models, voices and speech engines are available to you, and you choose between them. Which one actually answers a given turn also depends on what is being asked - a policy question or a complex refund may be handed to a deeper model even on a live call.
What is the difference between a model, a voice and a speech engine?
A model is what answers - the reasoning behind a reply. A voice is what your caller hears it said in. A speech engine is what SIMCOAI uses to understand what the caller said, including knowing when they have finished speaking.
Will the model or voice change without me knowing?
The underlying engine can change - models improve, prices move, providers have outages - without you having to re-choose anything, because you picked a configuration rather than a specific engine version. Where a change would alter how your service actually behaves, it is announced on the SIMCOAI updates page, and anything affecting availability is reported on the SIMCOAI status page.
Why does this page not name the AI provider behind each model?
Because the provider is not what you configured or chose - the SIMCOAI name is. Every provider SIMCOAI relies on is still named in full in the SIMCOAI privacy policy and GDPR and DPA page, because disclosing who processes your data is a legal requirement rather than a marketing choice.
