OpenCode (SST) v1.17.16–v1.17.18 — Grok Reasoning Variants, xAI PDF Support, Copilot Billing Fix
SST
Three patch releases shipped within 12 hours on July 9. v1.17.16 exposed reasoning effort variants for Grok models and improved xAI prompt cache routing with PDF file support; the desktop build added folder access actions and a composer menu for managing files without losing draft text. v1.17.17 improved Meta model handling for reasoning variants, added a dismissible tabs intro popup, refreshed the help entry point, and redesigned the revert dock for v2 sessions. v1.17.18 fixed a crash when GitHub Copilot returns models with zero billing batch sizes, and added a model-specific system prompt for Meta Muse Spark.
Why it matters
The Copilot billing crash fix addresses a regression affecting teams using GitHub Copilot as a model provider inside OpenCode; Grok reasoning effort variants give developers fine-grained cost/quality control.
