What Happened (Feb 6, 2026):
OpenAI released GPT-5.3-Codex, a specialized coding model that didn’t just learn to write software — it was used to debug its own training, manage infrastructure, and evaluate its own performance.
What You Need to Know:
OpenAI used early versions of Codex in a recursive loop, where the model helped fix training runs and improve itself.
The result is a model that’s 25% faster than its predecessor and far stronger at real-world engineering tasks.
On benchmarks, Codex scored 77.3% on Terminal-Bench 2.0, beating Anthropic’s Claude Opus 4.6 by ~12 points , and can now act as a computer operator, managing full software deployments.
Why It Matters:
This is a clear step toward self-improving AI systems — where models don’t just write code, they help evolve themselves.
#2 LATEST IN AI TODAY📎
What Happened (Feb 6, 2026):
Minutes after OpenAI’s launch, Anthropic released Claude Opus 4.6, introducing “Agent Teams” — multiple AIs coordinating to solve large problems together.
What You Need to Know:
Claude can now deploy multiple specialized agents, coordinated by a lead “manager,” instead of working as a single assistant.
In tests, 16 Claude agents built a 100,000-line compiler autonomously over 2,000 sessions.
Opus 4.6 also expands context to 1 million tokens, enabling long-running, complex engineering projects.
Why It Matters:
AI is shifting from single assistants to coordinated workforces, bringing software-scale productivity — and disruption — closer than ever.
