Problem or Motivation
Odysseus already supports OpenAI-compatible chat providers (OpenAI, OpenRouter, Groq, etc.) by base URL. Perplexity's API (https://api.perplexity.ai) is OpenAI-compatible and offers web-grounded models (default sonar-pro) with citations, but it isn't recognized as a first-class provider, so it shows up as a generic endpoint without a proper label or provider-specific headers.
Proposed approach
Recognize api.perplexity.ai as a first-class provider in src/llm_core.py, mirroring the existing OpenRouter pattern:
_detect_provider: map the perplexity.ai host → perplexity_provider_headers: send X-Pplx-Integration: odysseus/<APP_VERSION> via setdefault (mirrors the existing X-OpenRouter-Title convention; never clobbers caller headers)_provider_label: add the "Perplexity" label
Default model sonar-pro is already present in model_context.py. Backend-only; the frontend already ships a Perplexity logo + endpoint label. Minimal diff (3 files), provider tests added.
Area
API / Backend
Notes
This is a focused, single-feature proposal. Per CONTRIBUTING's guidance on agent-assisted contributions, opening this issue first. A draft PR implementing exactly this is ready (#3015) and can be linked — happy to adjust or hold if you'd prefer a different shape before review.
