Model ML is solving the “last-mile problem” in finance, carrying asks from research to analysis to a finished PowerPoint deck or Excel workbook with traceable sources.
When Model ML tested GPT‑5.6 Sol in its Composite, the results “blew every metric out the water,” says Co-founder and CEO Chaz Englander:
⚡ 21% fewer tokens per PowerPoint deck than Fable 5
✅ A 16.6 percentage-point lead over Opus 5 on decks ready for substantive review
📊 36% fewer tokens per Excel workbook than Opus 5
Watch Englander walk through Model ML’s evaluation process, then read the full story about how they use the model in production here: https://openai.com/index/model-ml/
Prompt caching can cut the input cost of long AI agent sessions dramatically—but only when your harness preserves reusable prompt prefixes. This video explains what prompt caching actually stores, why agent costs compound across turns, how provider behavior differs, and the implementation mistakes that invalidate your cache.

AI policy should be active, not academic. Greig Cowan (Head of AI & Data Science at NatWest) discusses shifting from static checklist reviews to a "Governance as Code" model where compliance checks run continuously at runtime and telemetry is gathered automatically.
