DeepSeek Harness Plugin better-model-provider: Declarative Inference Effort, Input Modality, and Capacity by Model

better-model-provider is a DeepSeek Harness (DSH) web plugin designed to address functional limitations caused by missing model capability declarations in OpenAI-compatible providers. This plugin offers a standalone settings interface, allowing users to declare and edit individual model capabilities without directly editing YAML configuration files. Its core features include customizing reasoning effort levels, configuring input modalities (such as enabling image input to avoid rejection), and editing context window sizes and maximum token capacities. The plugin supports sparse overrides for official catalog routes, saving only differences from default values and enabling one-click restoration. It also allows quick creation of declarations for unconfigured routes, though API keys still need to be managed through the official interface. Compatible with DSH 0.
