--== 6. LLM Abstraction Layer ==
--
--=== 6.1 Design Principle ===
--
--**FactHarbor uses provider-agnostic LLM abstraction** to avoid vendor lock-in and enable:
--
--* **Provider switching:** Change LLM providers without code changes
--* **Cost optimization:** Use different providers for different stages
--* **Resilience:** Automatic fallback if primary provider fails
--* **Cross-checking:** Compare outputs from multiple providers
--* **A/B testing:** Test new models without deployment changes
--
--**Implementation:** All LLM calls go through an abstraction layer that routes to configured providers.
--
------
--
--=== 6.2 LLM Provider Interface ===
--
--**Abstract Interface:**
--
--{{{

--  // Core methods
--  complete(prompt: string, options: CompletionOptions): Promise<CompletionResponse>
--  stream(prompt: string, options: CompletionOptions): AsyncIterator<StreamChunk>

--**Primary Provider (Default):**
--
--* **Anthropic Claude API**
--  * Models: Claude Haiku 4, Claude Sonnet 3.5, Claude Opus 4
--  * Used by default in POC1
--  * Best quality for holistic analysis
--
--**Secondary Providers (Future):**
--
--* **OpenAI API**
--  * Models: GPT-4o, GPT-4o-mini
--  * For cost comparison
--
--* **Google Vertex AI**
--  * Models: Gemini 1.5 Pro, Gemini 1.5 Flash
--  * For diversity in evidence gathering
--
--* **Local Models** (Post-POC)

--* **Rationale:** Fast, cheap, simple task

--
--**Stage 2: Claim Analysis** (CACHEABLE)
--
--* **Default:** Anthropic Claude Sonnet 3.5
--* **Alternative:** OpenAI GPT-4o, Google Gemini 1.5 Pro
--* **Rationale:** High-quality analysis, cached 90 days
--* **Cost:** ~$0.081 per NEW claim
--
--**Stage 3: Holistic Assessment**
--
--* **Default:** Anthropic Claude Sonnet 3.5
--* **Alternative:** OpenAI GPT-4o, Claude Opus 4 (for high-stakes)
--* **Rationale:** Complex reasoning, logical fallacy detection
--* **Cost:** ~$0.030 per article
