opencode v1.18.32: Bedrock image fix, Together AI streaming, new Zen models

opencode v1.18.32 shipped on September 21, 2026 with two core bugfixes and two community-driven additions to the Zen model list.

Core fixes

• Bedrock image attachments are now only hoisted for Claude, Nova, and Llama 4 models — other Bedrock models no longer receive attachments they can’t use.
• Together AI streaming usage reporting is fixed, restoring accurate token accounting on streamed responses.

Zen additions

Community contributor @dc85 added two models to OpenCode Zen:

• DeepSeek V4.1 Flash
• Grok 4.7 — also added to the Go SDK surface

Zen is opencode’s curated, tested model list billed through your opencode account — a zero-API-key path for teams without provider accounts. If you’re on Zen, both models are available now.
