Provider Guides

Loong currently ships 41 built-in provider kinds. This hub exists so the README and chooser pages can stay compact while every built-in provider still has a truthful setup page. Use Providers And Models when you are still choosing a lane. Use this hub when you already know the provider family and want the exact built-in contract, minimal config, and verification path.

Quick Picks

Use this short list when you want a fast starting point before scanning the full matrix below.

If you want…	Start here	Why
the shortest common hosted path	Volcengine	the platform-first hosted lane stays explicit and well-supported in the public docs
another common hosted path with the same shape	BytePlus	it keeps the hosted setup path short without hiding the broader provider inventory
a named direct hosted vendor your team already uses	OpenAI	the built-in direct hosted contract stays explicit instead of being flattened into one generic story
a coding-dedicated lane	BytePlus Coding or Kimi Coding	coding quota and model choice can stay separate from the main assistant lane
a local or self-hosted model server	Ollama	the operator-owned server boundary stays visible from the start
a gateway or compatibility endpoint	OpenRouter or Bedrock	route ownership stays explicit when another layer sits in front of the model vendor

Platform-First Hosted

Common hosted first-run lanes when you want a short reviewed path without hiding the provider family.

Provider	Kind	Default auth env	Model note

Bailian Coding	`bailian_coding`	`BAILIAN_API_KEY`	operator chooses model strategy

Gateway And Compatibility Providers

Gateway, proxy, or compatibility endpoints that sit between Loong and upstream model vendors.

Provider	Kind	Default auth env	Model note

Local And Self-Hosted Providers

Local or self-hosted servers where the model boundary stays operator-owned.

Provider	Kind	Default auth env	Model note
Ollama	`ollama`	local or explicit auth	operator chooses model strategy
LM Studio	`lm_studio`	local or explicit auth	operator chooses model strategy
llama.cpp	`llamacpp`	local or explicit auth	operator chooses model strategy
vLLM	`vllm`	local or explicit auth	operator chooses model strategy

Reading Rule

Start with Providers And Models when the provider choice is still open.
Use the individual guide page when one provider kind is already decided.
Keep Provider Recipes for representative rollout paths rather than the full provider inventory.
Keep Configuration Patterns open when you need the shared active_provider plus providers.<id> shape.
