Right tool for some jobs.
ChatGPT Enterprise is excellent for individual productivity. GPT-5.3 Codex tops the coding benchmarks. Frontier coordinates fleets of agents — for Fortune 500 customers with modern systems-of-record and an FDE budget. If you're a 500-bed hospital with a 15-year-old Epic install and no AI engineering team, Frontier doesn't have anything to orchestrate yet. GEIST ships the application that Frontier would otherwise need you to build first — and we route through Azure OpenAI when GPT is the right model.
Enterprise-grade chat for individual knowledge workers. Strong adoption among general office users; weak fit for organizational workflows that need shared state.
Coordination Engine for hundreds of autonomous AI co-workers across CRMs, ERPs, and ticketing. Forward Deployed Engineers paired in. Early adopters: Uber, State Farm, Intuit, HP, Oracle.
77.3% on Terminal-Bench 2.0. Strong agentic coding performance for engineering teams. Released alongside Frontier.
Frontier's value is orchestrating across modern, well-API'd systems-of-record. If your hospital is on a 15-year-old Epic install with no internal data warehouse, there's nothing to orchestrate yet — you need the application first. GEIST ships the application; Frontier sits on top later if you grow into it.
| Capability | OpenAI (Frontier, ChatGPT Enterprise, Codex) | GEIST |
|---|---|---|
| Production vertical applications | Frontier orchestrates agents across systems you already have | TalentGEIST, PayGEIST, DermGEIST, AgentGEIST, LearnGEIST ship as deployable applications |
| Mid-market deployment path | Forward Deployed Engineers required — Fortune 500 pricing | 12-week implementation playbook scoped for 500–5,000-employee organizations |
| Multitenant data isolation | Enterprise single-tenant — you architect tenancy if needed | Platform → Vertical → Instance → Tenant → User scope hierarchy with row-level security |
| Domain-aware integrations | Connects to your CRMs, ERPs via semantic layer (you supply the APIs) | 24 production integrations with domain schema knowledge: PeopleXD, Epic FHIR, HealthStream, Workday, Salesforce, M365, Slack, SharePoint… |
| Vertical playbooks pre-loaded | Frontier Partners (Abridge, Harvey, Sierra) cover specific niches | 6 platform playbooks ship today; AI Operating Model workstreams with pre-loaded assessments and ROI models; 13,720 ROI opportunities ready to go |
| Compliance posture (HIPAA, GDPR, audit) | SOC 2, ISO/IEC 27001/27017/27018/27701, CSA STAR — at the platform level | Reversible PII tokenization at app layer, GDPR cascade, append-only audit, Vertex BAA for HIPAA verticals |
| Customer-controlled deployment | OpenAI infrastructure | Customer Azure tenant, Hetzner, on-premise, or air-gapped |

An FDE engagement plus internal application build runs $1.1–1.5M+ in Year 1, with most of the cost going into the application around Frontier — the same application GEIST ships out of the box.
Frontier engagement
~$1.1M–1.5M+ Year 1
Forward Deployed Engineers (~$500K), internal team to build application logic ($400–600K), system-integration development ($200–400K). Custom enterprise pricing.
Agent orchestration across existing systems. Still need to build the application around it.
GPT-5.3 Codex custom build
~$1.2M Year 1
4 senior engineers × 12–18 months to build a multi-user application with database, sync layer, audit trail, multitenancy, and compliance.
Custom application that you own and must maintain forever.
GEIST
Weeks to deploy
Pre-built playbooks, 24 integrations, multitenancy and compliance baked in. We can use Azure OpenAI or any other provider via the multi-provider gateway.
Production vertical application running on your model of choice.
Year 1 totals; figures are estimates from internal cost analysis, not commitments.
GEIST routes through Azure OpenAI for GPT-5 series workloads when that's the best model for the job. Tenants on the Microsoft EA pay through their existing agreement; we provide the metering, attribution, and per-tenant billing wrapper that turns aggregate API spend into clean cost reporting.
Our multi-provider gateway means you're never locked to one vendor. Run Anthropic for legal reasoning, GPT for code generation, Vertex Gemini for HIPAA workloads, and local models for air-gapped — all in the same deployment, all metered per tenant.
