This page helps you **choose between LLM vendors** and **fix provider-looking bugs** that are actually schema, retrieval, orchestration, or eval drift. If you are new, start with the Orientation table and the FAQ. If you are debugging, jump to the Fix Hub.

## FAQ for newcomers

**OpenAI vs Azure OpenAI — are they the same?**  
Same models, different packaging. OpenAI = direct API and fastest releases. Azure OpenAI = Microsoft billing, VNet, compliance, data residency.

**Anthropic vs Claude — why two pages?**  
Anthropic is the company. Claude is the model family. We separate because “platform issues” and “model quirks” often need different fixes.

**Gemini vs Vertex AI — what is the relation?**  
Gemini is a model. Vertex AI is Google Cloud’s platform that runs Gemini and provides pipelines, eval, and deployment features.

**What makes Mistral special?**  
Efficient open-weights and MoE designs. Good cost/perf. Easy to host in your own infra.

**Meta LLaMA vs local LLaMA**  
Meta releases the weights. Community tools like `llama.cpp` let you run them locally on CPU or GPU.

**Groq LPU vs GPU**  
GPU is general purpose. LPU is a chip specialized for transformer inference. You get very low latency for chat workloads.

**Bedrock vs OpenRouter vs Together**  
Bedrock is an AWS enterprise gateway. OpenRouter is a community aggregator with OpenAI-style API. Together is an infra host for open weights with training and fine-tune options.

- Coverage ≥ 0.70 for the target section  
- λ remains convergent across three paraphrases and two seeds  
- E_resonance stays flat on long windows

## Fix in 60 seconds

1) **Measure ΔS**  
Compute ΔS(question, retrieved) and ΔS(retrieved, expected anchor). Stable < 0.40, transitional 0.40–0.60, risk ≥ 0.60.

2) **Probe λ_observe**  
Vary top-k and prompt headers. If λ flips, lock the schema and apply a BBAM variance clamp.

3) **Apply the module**  
Retrieval drift → BBMC + Data Contracts  
Reasoning collapse → BBCR bridge + BBAM  
Dead ends in long runs → BBPF alternate paths

4) **Verify**  
Coverage ≥ 0.70 on three paraphrases. λ convergent on two seeds.
