Releasev1.18.3114 September 2026

OpenCode

Restores ACP session model, effort, mode and reasoning chunk boundaries when loading, resuming or forking sessions, and requests summarized adaptive thinking for GitHub Copilot models.

It treats session continuity as part of the coding-agent interface, reducing state loss when work is resumed or forked across clients.

Aside

A browser agent that works across logged-in websites, local files and communications while keeping credentials out of the model and gating sensitive actions for confirmation.

It combines credentialed browser execution, local memory and approval controls in the browser itself instead of depending on per-service integrations.

What this changes

Teams now need to evaluate how agent systems preserve state across sessions and real actions, not only how well a model answers. Session recovery, credentials, approvals and local memory become product-level requirements when agents operate inside production workflows.
