Chatham scales its capital markets expertise with OpenAI
What happened: Chatham Financial integrated OpenAI’s Codex and the newly released GPT‑5.6 into its capital‑markets technology stack, redesigning key workflows.
Why it matters: The AI‑driven revamp trims trade‑validation from roughly 30 minutes to under 4 minutes, delivering faster deal execution and lower operational risk for a sector where speed is critical.
Key stats: Validation time reduced by over 85%, from 30 minutes to <4 minutes.
DevDay 2026 Recap
What happened: OpenAI announced over 20 new features, the flagship GPT‑6 Astra model, enhancements to ChatGPT, Codex, new APIs, tighter security controls, and a collection of builder‑focused tools.
Why it matters: GPT‑6 Astra promises higher reasoning and multimodal capabilities, giving developers a more powerful engine for complex apps. The expanded API suite and security upgrades lower integration friction and boost trust for enterprise adopters.
Key stats: • GPT‑6 Astra: 2× parameters of GPT‑5, 10‑fold speed boost. • 15 new APIs released, including real‑time data and image generation. • Security: end‑to‑end encryption for all API calls, role‑based access controls. • Over 5,000 developers signed up for early access within 48 hours.
Introducing GPT-6.1 Sol
What happened: OpenAI announced GPT‑6.1 Sol, a new AI model designed for advanced coding, computer interaction, and professional workflows. It delivers performance close to the Astra series but at only one‑fifth the standard API input and output token pricing.
Why it matters: The reduced cost lowers barriers for developers and enterprises to integrate powerful AI into products, enabling more extensive use cases—from code generation to complex office tasks—without the steep price tag of previous top‑tier models.
Key stats:
- Near‑Astra intelligence level for coding and professional work
- Token pricing: 20% of Astra’s standard rates
- Targeted at developers, enterprises, and power users seeking high‑performance, affordable AI
Basis completes a tax workbook 2x faster with GPT-6 Astra
What happened: GPT‑6 Astra processed Basis’s 50‑tab tax workbook in half the time required by GPT‑5.6 Sol, completing the task twice as fast.
Why it matters: Faster turnaround boosts productivity for tax professionals and builds confidence in deploying advanced language models for real‑world financial tasks.
Key stats:
- 50‑tab workbook processed 2× faster
- GPT‑6 Astra shows improved intent understanding
