Enum Provider 

pub enum Provider {
    ClaudeCode,
    Codex,
    Copilot,
    Gemini,
    OpenCode,
    Cursor,
    Hermes,
    Grok,
    Unknown,
}

Supported AI coding assistant providers.

Used both to tag a parsed session with its source assistant and to route per-provider usage aggregation. Provider::Unknown is the fallback when a model name matches none of the known prefixes.

Examples

use vct_core::models::Provider;

assert_eq!(Provider::from_model_name("claude-sonnet-4"), Provider::ClaudeCode);
assert_eq!(Provider::ClaudeCode.display_name(), "Claude");

Variants

ClaudeCode

Anthropic Claude Code.

Codex

OpenAI Codex CLI (also matches raw gpt-* / o1 / o3 model names).

Copilot

GitHub Copilot CLI.

Gemini

Google Gemini CLI.

OpenCode

OpenCode.

Cursor

Cursor CLI / IDE.

Hermes

Hermes.

Grok

xAI Grok CLI.

Unknown

Model name matched no known provider prefix.

Implementations

impl Provider

pub const fn from_model_name(model: &str) -> Self

Detects the AI provider from a model name using byte-level prefix matching.

Recognizes the claude, copilot, gemini, and grok prefixes, and treats gpt* / o1* / o3* model names as Provider::Codex. Matching is case-sensitive (lowercase) and operates directly on the UTF-8 bytes, so it stays const and allocation-free. Returns Provider::Unknown when no prefix matches.

Examples

use vct_core::models::Provider;

assert_eq!(Provider::from_model_name("gpt-4-turbo"), Provider::Codex);
assert_eq!(Provider::from_model_name("o3-mini"), Provider::Codex);
assert_eq!(Provider::from_model_name("gemini-2.0-flash"), Provider::Gemini);
assert_eq!(Provider::from_model_name("mystery-model"), Provider::Unknown);

pub const fn display_name(&self) -> &'static str

Returns the human-readable display name of the provider.

This is the same string produced by the std::fmt::Display impl.
