Expand description

el-cloud — opt-in frontier LLM cloud backend (ADR-010).

Implements el_core::LlmProvider over reqwest using the OpenAI Chat Completions API, which is supported natively by OpenAI, Anthropic (via compatibility layer), Ollama, and any OpenAI-compatible endpoint.

Provider routing is by model prefix:

  • "openai/<model>" → https://api.openai.com/v1
  • "anthropic/<model>" → https://api.anthropic.com/v1 (compat)
  • "gemini/<model>" → https://generativelanguage.googleapis.com/v1beta/openai
  • "ollama/<model>" → http://localhost:11434/v1 (no key required)
  • "http(s)://…/<model>" → custom base URL

The air-gap guarantee (ADR-004) is preserved: this crate is excluded from the default workspace build. Only apps that explicitly construct a CloudProvider opt into outbound network calls.

§wasm32 note

reqwest::blocking is unavailable on wasm32-unknown-unknown (no threads). The async reqwest surface exists there, but LlmProvider::chat() is synchronous and cannot await the browser’s fetch. The el-ffi wasm32 cloud constructor therefore throws an explicit “unavailable” error (ADR-010 amendment), and this crate’s network modules are gated to non-wasm32.

CloudProvider
Frontier LLM cloud backend. Construct one per session; it owns a reqwest::blocking::Client that reuses the TCP connection pool.
