2026-10-24-opencode-configured-reasoning-options-generate-model-variants-in-both-majors
Configured reasoning options generate model variants in both majors. V1 commit d12161eecd9886b820fc438921c06a0b3ca58d3b first ships in v1.19.3, absent from v1.19.2. V1 uses configured reasoning_options; V2 uses capabilities.reasoning. In each major, configured reasoning regenerates the base variants before explicit variant overrides apply. V2 commit d889cb20447f3b31d88719786f46a1a75ed2e6fa first ships in v2.0.31, absent from v2.0.30.
Channel: tagged-release. Half: capability. Date: 2026-10-16.
Operator consequence: Custom/provider-compatible models can expose reasoning controls through configuration instead of a custom adapter. Recheck variant names and provider request settings when adopting this behavior. This is the V1.19.3 capability omitted even though its release appears in the ledger.
