Model metadata card

Contains all metadata needed for compression, token counting, and optimization.

Fields

id: String

Full model ID (e.g., “openai/gpt-4o”)

abbrev: String

Short abbreviation for compression (e.g., “og4o”)

provider: Provider

Provider

encoding: Encoding

Tokenizer encoding

context_length: u32

Context window size (max input + output tokens)

defaults: HashMap<String, Value>

Default parameter values (for removal during compression)

supported_params: HashSet<String>

Supported parameters

pricing: Option<Pricing>

Pricing information (optional)

supports_streaming: bool

Whether this model supports streaming

supports_tools: bool

Whether this model supports function/tool calling

supports_vision: bool

Whether this model supports vision/images

Implementations

impl ModelCard

pub fn new(id: impl Into<String>) -> Self

Create a new model card with auto-generated abbreviation

pub fn with_abbrev(id: impl Into<String>, abbrev: impl Into<String>) -> Self

Create model card with explicit abbreviation

pub fn encoding(self, encoding: Encoding) -> Self

Builder: set encoding

pub fn context_length(self, context_length: u32) -> Self

Builder: set context length

pub fn pricing(self, pricing: Pricing) -> Self

Builder: set pricing

pub fn with_tools(self) -> Self

Builder: enable tools support

pub fn with_vision(self) -> Self

Builder: enable vision support

pub fn generate_abbrev(id: &str, provider: Provider) -> String

Generate abbreviation from model ID

The abbreviation scheme:

1. Provider prefix (1-2 chars): o=OpenAI, m=Meta, mi=Mistral, etc.
2. Compressed model name: remove common prefixes, compress version numbers

Examples:

• openai/gpt-4o -> og4o
• meta-llama/llama-3.1-405b -> ml31405b
• deepseek/deepseek-v3 -> dv3

impl ModelCard

pub fn from_openrouter(model: OpenRouterModel) -> Self

Create ModelCard from OpenRouter API model
