OpenCode model configuration cost input output cache read official documentation
💡 Result:
OpenCode is an open-source AI coding agent that supports a wide range of LLM providers and models [1][2]. Its configuration and pricing structure are integrated through its model catalog, which utilizes specific schemas for cost management [3][4][5]. Model Configuration and Cost Structure OpenCode models are configured via the system's catalog, which defines operational parameters and costs [3][5]. Official model definitions use a specific schema that includes input/output costs and, where applicable, cache-related pricing [4]. The cost schema includes the following parameters [4]: - input: Cost per unit (typically per 1 million tokens). - output: Cost per unit (typically per 1 million tokens). - cache.read: Cost per unit for reading cached tokens [4]. - cache.write: Cost per unit for writing cached tokens [4]. These costs are often tracked in a pay-as-you-go format for models accessed through OpenCode Zen or other integrated providers [6][7]. Important Limitations and Known Issues Users should be aware of a known limitation regarding cache-related costs: - Cost Calculation Discrepancy: Reports indicate that while the cost.cache.read field is correctly stored in the model configuration, it is sometimes ignored by the internal billing/cost calculation engine [8]. This can lead to displayed session costs appearing lower than the actual billed amount when significant prompt caching is utilized [8]. Configuring Models - Global Configuration: You can configure model settings globally in your OpenCode configuration files (opencode.json or opencode.jsonc) [5]. - Model Selection: Models are selected using the provider_id/model_id format [9][10]. - Preloaded Providers: Popular providers are preloaded, and users can connect additional providers via the /connect command [9][1]. - Custom Providers: Users can define custom providers and models within their configuration, where they specify the required metadata, including cost structures [8][9]. For the most accurate and up-to-date pricing for specific models (such as those in the Zen collection), users should refer to the official OpenCode documentation pages [6][7].

Pass the cached-input price to OpenCode.
The catalog parses cached_input_per_mtok, but CatalogPrice, LaunchOpenCodeCloud, and BuildOpenCodeCloudConfig pass only input and output. OpenCode defines cached-input pricing as cost.cache.read, so its cost display omits cached-token pricing.
Add the field and emit cost.cache.read with the catalog’s micro-dollars-per-million-token conversion.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Restrict passthrough detection to the selected top-level subcommand.
SplitPassthroughArgv runs before CLI11 parses --home, so it treats the value claude-code as the passthrough subcommand. It inserts -- before run. CLI11 then treats run as positional input instead of a subcommand, and the valid command fails parsing. Consume global option values before detecting the subcommand, and add a regression case for wally --home claude-code run model prompt.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Keep the fallback output limit below the model’s shared budget.
When max_output_tokens is absent, this fallback sets limit.output equal to limit.context for windows up to 65,536 tokens. OpenCode treats these as separate input and output limits, but the catalog contract allows models with no output cap to share one input/output budget. A non-empty prompt plus the full-window output allowance can exceed that budget. Use a strictly smaller fallback and add a regression test with a small context window and max_output == 0.

Makes the shim harnesses size themselves from the real model instead of guessing at a default.
What's in it:
Tests cover the catalog fetch, the limit/cost injection, and flag passthrough.
