MCP Won the Protocol War: Build-vs-Buy Math for Your Own Deploy MCP Server
OpenAI adopted rival Anthropic's MCP and the protocol now lives under the Linux Foundation, so the standards bet is settled. What remains is the build-vs-buy math for your own deploy and rollback MCP server, with real 2026 cost envelopes.
Railway Agent Runs on Your ChatGPT Subscription: What BYO-Model Billing Concedes About PaaS Agent Margins
Railway's September changelog lets Railway Agent bill to your ChatGPT plan instead of its own meter. The math behind the move: token margins now belong to the model vendor, and platforms are left competing on agent UX and compute.
OpenAI Buys Ona (Formerly Gitpod) for Its Cloud Sandboxes, Not Its Dev Environments
OpenAI's acquisition of Ona (formerly Gitpod) confirms that agent sandboxes, not dev environments, are the durable product of the cloud-CDE era — and narrows the self-hostable path for agent compute. A concrete comparison of vendor-owned versus self-hosted execution.
Temporal Went From $5B to $12.5B in Seven Months: Why Deploy-From-Chat Agents Need Durable Execution
Temporal's $550M raise at $12.55B and its GA OpenAI Agents SDK integration mark durable execution as production-required for agents. A worked deploy-from-chat crash scenario shows what breaks without it, plus a cloud vs self-hosted vs lighter-engine decision guide.
E2B vs Daytona vs Modal: Picking an Agent Sandbox You Can Self-Host
E2B, Daytona, and Modal now ship as native providers in the OpenAI Agents SDK — but only one is still open-source and self-hostable. A numbers-backed comparison of boot times, isolation tech, GPUs, and licenses, with a build-vs-integrate verdict for self-hosted PaaS roadmaps.
E2B Is Now Native in OpenAI's Agents SDK: The Bar a Self-Hosted Agent Sandbox Has to Clear
OpenAI's Agents SDK declares E2B sandboxes natively since April 2026. This post turns that integration into a six-part checklist — cold start, isolation, templates, lifecycle, MCP sandboxing, egress policy — and scores four self-hosted paths against it.
OpenAI's Presence Ships With Engineers, Not a Deploy Button: What the Gap Between Enterprise Agents and Git-Push Reveals
OpenAI launched Presence with engineer-led deployments instead of a self-service console. A decomposition of its six-stage process shows which half genuinely needs consultants — and which half is deploy-and-operate mechanics a git-push platform already made a one-command path.
OpenAI Adopted Anthropic's Agent Skills Format in 48 Hours — What That Means for Your Deploy Runbooks
OpenAI adopted Anthropic's Agent Skills packaging format within 48 hours of its release, not just its MCP protocol. Here's what that convergence changes about writing a portable runbook Skill instead of a bespoke one.
Gitpod Bet the Company on Self-Hosted Agent Infra — Then OpenAI Bought It
Gitpod rebranded to Ona and went self-hosted-only in September 2025. Nine months later OpenAI bought it for Codex. Here's what a hyperscaler choosing to buy customer-owned execution instead of building it actually signals.
