OpenAI Consulting. Deployed by Practitioners.
We deploy ChatGPT Enterprise, integrate GPT-5.4 and the Responses API, set up Codex for engineering teams, build agentic workflows with the Agents SDK, and create custom GPTs for businesses that want real AI infrastructure -- not a chat window.

Why OpenAI for Business
OpenAI has the largest AI ecosystem in the world. Hundreds of millions of weekly active ChatGPT users, thousands of enterprise deployments, and an API that powers everything from customer support chatbots to autonomous coding agents. When a business asks "where do we start with AI," the answer is almost always somewhere in the OpenAI stack. The question is which products, which models, and how to deploy them without burning budget on the wrong approach.
The product lineup has expanded fast. ChatGPT Enterprise gives organizations a secure workspace with SSO, admin controls, 60+ app connectors, a Compliance Logs Platform, and data privacy guarantees. The OpenAI API now offers GPT-5.4 as the flagship (Instant, Thinking, Pro, and Nano variants), o4-mini for cost-efficient reasoning, and o3 for deep multi-step reasoning. The Responses API handles agentic loops with built-in web search, code interpreter, file search, and function calling -- replacing the now-deprecated Assistants API. And Codex gives engineering teams an autonomous coding agent -- now available as desktop apps, CLI, and IDE extensions with 3M+ weekly active developers. Powered by GPT-5.3-Codex, it writes, tests, and ships code in sandboxed environments while your team focuses on higher-level work. Each product solves a different problem, and most businesses need a combination.
Where OpenAI particularly excels is breadth of integration. The API is the most widely supported LLM endpoint in the industry -- virtually every SaaS tool, automation platform, and developer framework has native OpenAI support. OpenAI has also released gpt-oss -- open-weight models under Apache 2.0 that run on a single GPU for self-hosted and edge deployments. That means faster time-to-production for custom builds and real options for on-premise workloads. For customer-facing applications where latency, output consistency, and multimodal capabilities matter, GPT-5.4 is the current benchmark.
We're a certified OpenAI deployment partner and we're also deep practitioners of Anthropic's Claude. That dual expertise matters. We don't push one vendor -- we recommend the platform that fits your use case, compliance requirements, and budget. Some clients run OpenAI for customer-facing features and Claude for internal development. Others go all-in on one. We help you figure out the right architecture, then we build it.
What We Build
OpenAI implementation across the full product stack -- from ChatGPT Enterprise admin to custom model fine-tuning. Every layer, configured for your business.
ChatGPT Enterprise / Team Deployment
Full rollout of ChatGPT Enterprise or Team -- SSO via SAML, SCIM provisioning, 60+ app connectors (Google Drive, Slack, Salesforce, GitHub), Compliance Logs Platform, custom data retention policies, and team onboarding. GPT-5.4 access across Instant, Thinking, and Pro tiers. We handle admin setup so your team starts producing on day one.
OpenAI API Integration
Production-grade API integration with GPT-5.4, GPT-5.3, o3, and o4-mini models. Structured outputs via the Responses API, streaming, function calling, token optimization, rate limiting, error handling, and cost management. We build it to scale, not to demo.
Codex Deployment
Deploy OpenAI's Codex for your engineering team -- now available as desktop apps (macOS/Windows), CLI, and IDE extensions with 3M+ weekly active developers. Powered by GPT-5.3-Codex, it runs tasks in sandboxed cloud environments, writes and runs tests, creates pull requests, and handles multiple tasks in parallel. We configure GitHub integration, repository onboarding, Plan Mode workflows, and coding convention alignment so your engineers delegate from day one.
Custom GPTs & GPT Store
Design and build custom GPTs tailored to your internal workflows -- onboarding assistants, policy lookup tools, data analysis bots, customer support agents. Publish to your organization's private GPT Store or deploy externally.
Responses API & Agents SDK
Build intelligent applications using the Responses API (replacing the deprecated Assistants API) with function calling, code interpreter, file search, and web search built in. Stateful conversations via the Conversations API, agentic loops with multi-tool orchestration, and the Agents SDK for multi-agent workflows with native sandbox execution. We also deploy the Realtime API for production voice applications.
Fine-Tuning & Custom Models
Supervised fine-tuning and reinforcement fine-tuning (RFT) on o4-mini. Training data preparation, evaluation benchmarks, A/B testing against base models, and production deployment. We determine whether fine-tuning, RAG, or prompt engineering is the right fit before you spend the compute.
Enterprise Compliance & Security
SOC 2-aligned deployment, data residency configuration, SSO enforcement, audit logging, DLP controls, and API key management. We set up the guardrails so your security team approves the rollout and your data stays where it should.
Multi-Model Strategy & Orchestration
Build routing logic that sends queries to the right model -- GPT-5.4 Instant for speed, GPT-5.4 Nano for edge deployment, o4-mini for cost-efficient reasoning, and o3 for deep multi-step reasoning. Plus gpt-oss open-weight models for self-hosted workloads. Intelligent fallback chains, cost optimization, and latency management across the full lineup.
Built Across the Full AI Stack
We don't believe in single-vendor lock-in. The best AI architecture for your business might use OpenAI for some things and a different platform for others. We're certified with both OpenAI and Anthropic and deploy across every major cloud provider. Here's what that looks like in practice.
Most of our clients start with one platform and expand. A common pattern: deploy ChatGPT Enterprise for business teams, integrate the OpenAI API for customer-facing features, and use Claude Code for engineering workflows. We help you design that architecture from day one so the pieces fit together instead of competing.
Why OneWave for OpenAI
We're not a generalist consultancy that discovered AI last year. We deploy OpenAI products daily, understand the tradeoffs between models, and have shipped real implementations across dozens of businesses. Here's what differentiates our approach.
How We Work
Four phases. Thirty days to measurable results. Every engagement follows the same structure -- adapted to your business, not templated.
Audit
We map your current workflows, tech stack, and team capabilities. We identify where OpenAI products save the most time and flag quick wins you can ship in the first week.
Strategize
We build a prioritized deployment roadmap. Which models to use, which teams get Codex and how to structure async task delegation, what custom GPTs to build, where the API fits, and in what order. Clear milestones, no ambiguity.
Build
We deploy ChatGPT Enterprise, configure Codex for your repos, build custom GPTs, integrate the API with the Responses API, and wire up your Agents SDK workflows. Production infrastructure, not prototypes.
Train
Hands-on training for every role. Engineers learn Codex -- async task delegation, PR review workflows, and parallel task management. Ops teams learn custom GPTs and prompt engineering. Leadership understands cost management and what to measure. You walk away self-sufficient.
