​Created by Roomote. Follow up by mentioning @roomote, in the web UI, or in Discord.

What changed

All 35 models currently returned by OpenCode Go now have complete metadata in the single opencodeGoModels registry, including limits, capabilities, pricing, and descriptions. Live endpoint metadata still overrides volatile fields when supplied. Qwen models use the Messages API where required; GPT-5.6 Luna, Grok 4.6, and Muse Spark use their documented Responses API route; Grok 4.5 follows Chat Completions.

Independent registry expectations cover the curated metadata, including corrected GLM-5.3 Flash and HY3 prices, conservative peak pricing for DeepSeek V4 Flash Vision Exp, Luna's max-output control, Muse Spark 1.3, and Omen Alpha.

Why this change was made

Models without a registry entry inherited a generic 200k context window, causing incorrect context percentages. Incorrect prices understated displayed costs, while split metadata and incorrect wire-format routing could silently produce inconsistent controls or failed requests.

Impact

The context meter, model controls, cost estimates, and request routing now resolve from one current model registry. Time-varying DeepSeek Vision costs use the conservative peak rate until the shared model schema can express schedules. Unknown future IDs retain the safe generic fallback until their metadata is curated.

Consolidated all 33 OpenCode Go model records into opencodeGoModels and removed the separate limits registry/helper. The registry now carries limits, capabilities, pricing, and descriptions for every current live ID, with exact membership and metadata invariants covered by tests. Full workspace tests, lint, and type checks pass.

and its cost-calculation path to represent OpenCode Go’s UTC weekday peak
schedule (01:00–04:00 and 06:00–10:00) alongside off-peak rates, selecting peak
prices only during those periods. If ModelInfo cannot express time-based
pricing, use the peak rates as conservative static values and update the related
opencode-go tests.
