This is similar to a runtime swap: same UI, different inference backend

Interactions API GA: Orchestrate Across Models and Agents
By
–
Today we are shipping the Interactions API into GA, our new API designed to let you orchestrate across models and agents in the same interface, and is our new default API going forward. Interactions sets the stage for the new era of Agents : )

OpenAI Daybreak models discover and patch critical vulnerabilities
By
–
We're accelerating patching, in addition to vuln finding, with new tools and models in OpenAI Daybreak. Our models are now discovering and generating patches for critical vulns in major browsers, network infrastructure, and operating systems (such as FreeBSD and the Linux

Keep system prompts under 200 lines for better adherence
By
–
4/ Keep it short. This is the part people get wrong. The docs say stay under 200 lines, ideally around 100. A model reliably follows about 150 instructions at once, and Claude Code's own system already uses a chunk of that. A bloated file makes Claude follow less, not more.

Delos Workers: AI agents with persistent identity and memory
By

Most AI agents reset the moment a task ends: you prompt, it runs, the context is gone.
— Chubby♨️ (@kimmonismus) 22 juin 2026
Delos Workers is built on the opposite assumption: Each agent keeps a standing identity and persistent memory, with its own email, phone number and Slack handle, so it carries context between… https://t.co/n2lCH5ZW3KMost AI agents reset as soon as a task ends: you give an instruction, it executes, the context disappears. Delos Workers is based on the opposite hypothesis: each agent maintains a permanent identity and persistent memory, with its own

Sakana Fugu: orchestrator rivaling Fable 5, not independent model
By
–
After examining the new Sakana Fugu model, which, as they present it, rivals Fable 5, I want to comment that this is in itself not a new independent model, but an orchestrator trained to orchestrate several different models (e.g., Opus 4.8, GPT

Sandboxes: serverless speed and persistent state
By
–
Sandboxes must achieve 2 things at the same time… The speed of a serverless function. You cannot make an agent wait 2 minutes for a VM to start. It must offer the persistent state of a complete machine. Agents are not

Real-time streaming inference model for interactive worlds
By
–
/5 An interactive world isn't truly interactive if it lags. This model is built specifically for real-time streaming inference. Using DMD-style distillation and an autoregressive rolling KV cache, it generates environments chunk-by-chunk from noise. When paired with asynchronous

AI Governance Problem: The Real Challenge for Companies

Most companies do not have an AI problem. They have an AI governance problem. As agents move across systems, data, and workflows, the real challenge becomes: Visibility Control Accountability Microsoft’s Agent 365 updates point to the next enterprise bottleneck:
