The platform

Build on one sovereign AI stack. Frontier models, agentic orchestration, and verifiable infrastructure.

Coding agents

Power your coding agent

Connect OpenCode, ForgeCode, Crush, or Pi to Corti Models with one command. The CLI signs you in, picks a default model, and writes the agent config for you.

Set up your coding agentCorti Models
app.py
from openai import OpenAI client = OpenAI(− base_url="https://api.openai.com/v1",+ base_url="https://ai.eu.corti.app/v1",− api_key=OPENAI_API_KEY,+ api_key=CORTI_API_KEY,) model="corti-s1"

Drop-in API

Replace your LLM provider

Point any OpenAI-compatible app at Corti Models by changing two values, the base URL and the API key. Streaming, tool calling, JSON mode, and the Responses API work unchanged.

Optimized inference

Optimize your compute

Get fast, optimized inference on the GPUs you already own, or on ours. Corti brings the serving, optimization, and model catalog, on-prem or on any cloud, so you get more out of every GPU you pay for.

Agentic Framework

Deploy agents on a governed execution and control layer

Build your agents on Corti and integrate them deeply with your systems through Corti connectors, MCP, and A2A compatibility. In production, the platform orchestrates each run, enforces guardrails, and records an audit trail of every step.

Speech to Text

Capture clinical speech accurately

Stream dictation and conversations, or process batch audio, in ~50 languages. Catch the clinical terms general speech models miss.

Transcribe audioRead the docs

Medical Coding

Predict codes with clinical evidence

Receive ranked ICD-10, CPT, and SNOMED CT codes with source evidence and reasoning. Adapt to new code sets without retraining your models.

Automate codingRead the docs

Text Generation

Generate documentation you can trust

Turn conversations into notes, letters, and summaries shaped by your templates, with every output grounded in the source conversation.

Generate textRead the docs

Sovereign Cloud

Run AI under your chosen jurisdiction

Choose EU or US hosting, your cloud partner, or your own hardware. Keep the same APIs and control where your data and models live.

Who builds on Corti

Built for industries where mistakes have consequences. Ready for critical industries.

  • EHR vendors. Embed dictation, ambient documentation, and coding in the record, ready for your workflows.

    Learn more

  • Practice management systems. Add documentation, coding, and admin automation to the tools clinics already run on every day.

    Learn more

  • Virtual care. Turn every remote consultation into a structured note, codes, and follow-up in real time.

    Learn more

  • Ambient scribes. Build your scribe on clinical-grade speech to text instead of maintaining the stack yourself.

  • Dictation and voice platforms. Replace legacy dictation engines with clinical-grade speech to text and voice commands.

  • Revenue cycle management. Code with evidence, draft prior authorizations, and appeal denials with an audit trail.

  • Pharma. Run frontier models and agents on proprietary research and data that stays under your control.

  • AI-native consultancies. Deliver production AI for regulated clients on models and guardrails that clear review.

Compliance by design

Security, privacy, and auditability built into every layer. Not bolted on after the fact.

Explore compliance

  • Security

    FIPS-compliant encryption at rest and in transit, per-customer keys, and role-based access with audit logging. Geo-distributed with automated failover, monitored by DRATA.

  • Privacy

    Data minimization and tenant isolation by default. Host in the EU or on-premises without forced transfer. Customer data is never used to train general-purpose models.

  • Operations

    Audit trails, change logs, and version control across the platform. Regular pentests, live failover, and incident response with root-cause documentation.

  • ISO 27001
  • ISO 42001
  • GDPR
  • NIS2
  • DORA
  • EU AI Act
  • HIPAA
  • SOC 2 Type 2

Generalist labs are built for general purposes. High-stakes deployments in critical industries need more. Corti was forged in the complexity of healthcare, so the hard work of making AI accurate, compliant, and auditable is already done.

Our models and APIs are benchmarked on real clinical data, compliance is built into the stack, you choose where your data runs, and every output is traceable. Your team gets to focus on the product.

Symphony is Corti's family of agentic models for healthcare. It powers Speech to Text, Text Generation, and Medical Coding as orchestrated pipelines that reason, check, and correct, so every output comes back structured, grounded in evidence, and ready for your application to act on.

Learn about Symphony

Yes. Symphony ranks #1 on medical speech, coding, and agent reasoning benchmarks, including 98.6% word accuracy in English real time and 74% F1 on medical coding, ahead of OpenAI, Anthropic, and Google. Our research is published at NeurIPS, ICML, ICLR, and ACL, and we release our benchmark datasets openly so anyone can check the results.

Any industry where an AI error has real consequences and the work answers to a regulator. Healthcare and life sciences come first, along with the EHR vendors, scribes, revenue cycle platforms, and consultancies that serve them. If your output lands in a patient record, a claim, or an audit trail, you are building for a critical industry.

You choose the region or run on-premises. Every request runs on infrastructure Corti operates, with hardware attestation, and nothing is stored or used for training. We bring documentation for GDPR, HIPAA, NIS2, DORA, and the EU AI Act to the first meeting.

Pay for what you use. Every API draws from one credit balance, and the same credits work across development, testing, and production. Start with $50 in free credits, no card required. For teams that want hands-on help, the Acceleration Pack adds monthly credits, development hours, and an architecture review.
