+This module used to bridge between openai SDK 0.x and 1.x exception types.
-- OpenAI < 1.0 (old API with openai.error module)
+Since we no longer depend on the `openai` SDK at all (we call HTTP directly
-- OpenAI >= 1.0 (new API with direct exception imports)
+via :mod:`models.openai.openai_http_client`), this file now provides:
+
+1. Pure Python exception classes that match the *names* the rest of the
+   codebase already imports (RateLimitError / Timeout / APIError /
+   APIConnectionError / AuthenticationError / InvalidRequestError ...).
+2. A :func:`map_http_error` helper that converts an
+   :class:`OpenAIHTTPError` (or any HTTP status code + message) into the
+   appropriate exception subclass, so existing ``except RateLimitError``
+   ``except Timeout`` etc. blocks keep working unchanged.
+
+This keeps the behavior of all existing bots (rate-limit backoff, timeout
+retry, auth-error fast-fail) identical to the openai-SDK-based version, while
+removing the hard dependency on the `openai` package.

+Lightweight HTTP client for OpenAI-compatible APIs.
+
+This client is a drop-in replacement for the parts of the `openai` SDK that this
+project actually uses (chat completions, completions, image generation), so we
+can drop the hard dependency on `openai==0.27.x`.
+
+Design goals:
+- Pure `requests` based (no httpx / pydantic / openai SDK dependency).
+- Returns plain `dict` responses with the same shape OpenAI's HTTP API returns,
+  so existing code that does `response["choices"][0]["message"]["content"]` /
+  `response["usage"]["total_tokens"]` keeps working.
+- Streaming yields plain `dict` chunks (parsed SSE `data:` JSON), matching the
+  shape that `agent/protocol/agent_stream.py` consumes:
+    chunk["choices"][0]["delta"]["content" | "tool_calls" | "reasoning_content"]
+    chunk["choices"][0]["finish_reason"]
+  Plus dict-style error chunks: {"error": True, "message": ..., "status_code": ...}
+- Compatible with arbitrary OpenAI-compatible endpoints (LinkAI, Azure-style
+  proxies, DeepSeek, Moonshot, etc.) by allowing per-call api_key / api_base
+  override and trusting whatever path/payload shape the caller passes.
