Chatham Financial is integrating OpenAI's Codex and GPT-5.6 models into its capital markets workflows, significantly reducing the time required for routine tasks like trade validation.
- The firm reengineered its trade validation process using a Codex-built application, cutting review time from approximately 30 minutes to under 4 minutes.
- Internal applications built on Chatham Vibes run on GPT-5.6 Terra by default, supporting client-facing workflows such as pricing workbooks and hedging dashboards.
- The next-generation operating system Chatham Onyx leverages multiple models including GPT-5.6 Sol, GPT-5.4, and GPT-4.1 to manage assets, debt, and derivatives with traceable AI assistance.
- Codex is used across the development lifecycle of Onyx to help plan, build, test, and document software capabilities.
This integration allows Chatham's experts to spend less time assembling information and more time applying professional judgment to complex client cases.
