# `Arcanum.Adapters.OpenAI`
[🔗](https://github.com/kakilangit/arcanum/blob/v0.1.0/lib/arcanum/adapters/openai.ex#L1)

Inference adapter for OpenAI-compatible APIs.

Handles wire protocol translation only:
- Request serialization (messages, tools, provider routing)
- System role demotion at serialization time (profile-driven)
- Response parsing (faithful field mapping, no model-specific fallbacks)
- Retry on transient HTTP errors (429, 502, 503, 529)

Model-specific normalization (content fallback from thinking, XML tool-call
extraction) is handled by `Response.Normalizer` in the Gateway layer.
