OpenCode v1.18.30 (Sept 9) adds the Astra system prompt for GPT-6 models, preserves Bedrock DeepSeek model IDs including ARN-based ones, updates SDK compatibility for Azure and OpenAI providers, and adds reasoning-effort variants for GitLab GPT/Claude models. The project's GitHub repo now resolves to anomalyco/opencode rather than sst/opencode.

Why it matters

OpenCode is one of the most-starred open-source coding agents (206k stars); its provider-compatibility releases are what keep third-party model routing working.
