Llama + Qwen API Access
Choose Authorized Routes, Test Exact ModelsLlama 与 Qwen API 接入：选择授权路由，测试准确模型
Llama and Qwen are model families available through multiple routes. Production access must identify the exact model, operator, protocol, rights, region and capabilities.
Llama 与 Qwen 是可通过多种路由访问的模型族。生产接入必须识别准确模型、运营方、协议、权利、区域与能力。
TL;DR
Use official services, approved cloud platforms, gateways or lawful self-hosting.
Family names are not endpoints; record model ID, snapshot, operator and region.
Verify tools, structured output, streams, context, modalities, errors and usage.
Use a stable internal contract while preserving provider-native evidence.
使用官方服务、获批 Cloud Platform、网关或合法自托管。
模型族名称不是端点；记录模型 ID、Snapshot、Operator 与 Region。
验证工具、结构化输出、流、上下文、模态、错误与用量。
使用稳定内部契约，同时保留供应商原生证据。

Meta documents Llama model access directly and through partners or cloud platforms. Qwen services are available through Alibaba Cloud Model Studio interfaces, with endpoints, keys and model availability that can differ by region.
Meta 文档说明 Llama 可直接或通过合作伙伴与 Cloud Platform 获取。Qwen 服务可通过阿里云百炼接口访问，而端点、密钥与模型可用性可能因区域而异。
Open-source weights and hosted APIs are different products. A self-hosted model needs verified license rights, artifact provenance, serving infrastructure, security, updates and its own API contract.
开源权重与托管 API 是不同产品。自托管模型需要验证 License 权利、Artifact 来源、Serving Infrastructure、安全、更新与自身 API 契约。
From a model family name to a verified API call从模型族名称到一次可验证的 API 调用
Do not paste “Llama” or “Qwen” into production configuration as if it were an endpoint. First choose an authorized operator and region, copy the exact base URL and model ID from that operator's current documentation, and create a provider-scoped key. Alibaba Cloud Model Studio, for example, supports OpenAI-compatible Qwen calls and requires a region-specific workspace URL.
不要把“Llama”或“Qwen”当成端点直接写入生产配置。应先选择获授权的运营方和区域，从该运营方最新文档复制准确的 Base URL 与 Model ID，并创建供应商范围内的密钥。例如，阿里云百炼支持以 OpenAI-compatible 方式调用 Qwen，同时要求使用与区域对应的 Workspace URL。
Record operator, account, workspace, region and the official documentation URL.记录 Operator、Account、Workspace、Region 与官方文档链接。
Use the exact model ID exposed by that route, not the family name.使用该路由公开的准确 Model ID，而不是模型族名称。
Capture status, model identity, usage, latency and provider request ID.记录 Status、Model Identity、Usage、Latency 与 Provider Request ID。
Verify streaming, tools, JSON output, context limits and error behavior separately.分别验证 Streaming、Tools、JSON Output、Context Limit 与 Error Behavior。
import os
from openai import OpenAI
client = OpenAI(
api_key=os.environ["MODEL_API_KEY"],
base_url=os.environ["MODEL_BASE_URL"],
)
response = client.chat.completions.create(
model=os.environ["MODEL_ID"],
messages=[{"role": "user", "content": "Reply with exactly: route verified"}],
temperature=0,
)
print(response.model)
print(response.usage)
print(response.choices[0].message.content)Use this pattern only when your selected operator documents OpenAI compatibility. For Qwen, follow the current Alibaba Cloud Model Studio region and workspace instructions. For a Llama route, use the exact protocol, endpoint and model ID documented by the selected authorized operator.
仅当所选运营方明确支持 OpenAI compatibility 时使用此模式。Qwen 应遵循阿里云百炼当前的 Region 与 Workspace 说明；Llama 路由则应使用所选授权运营方文档中的准确协议、Endpoint 与 Model ID。
After the smoke test passes, continue with the OpenAI-compatible API provider guide and the LLM provider migration checklist.

- Record operator, exact model ID, endpoint, region, license and terms.
- Run golden chat, tool, schema, stream, limit and error tests.
- Compare native usage, quality, latency and failure behavior by workload.
- Canary the adapter and retain the previous route and configuration.
- 记录 Operator、准确模型 ID、端点、Region、License 与 Terms。

Use a stable contract with explicit adapters使用稳定契约与显式适配器
The application sends a workload alias, required capabilities and trace context to a stable internal interface. Policy filters authorized routes. A provider adapter translates only necessary protocol differences and returns normalized output plus exact provider and model evidence.
应用向稳定内部接口发送工作负载别名、Required Capability 与调用链上下文；策略过滤授权路由；供应商适配器只转换必要协议差异，并返回标准化输出以及准确供应商与模型证据。
Production rule: never route by the words Llama or Qwen alone; select an authorized endpoint with an exact tested model ID.
生产规则：绝不能只凭 Llama 或 Qwen 名称路由；必须选择具有准确且已测试模型 ID 的授权端点。
Add external capabilities above either model family在任一模型族之上增加外部能力
Whether inference uses Llama or Qwen, QVeris provides governed Discover → Inspect → Call access to external APIs, tools, services and live data. Keep tool credentials and execution evidence separate from model adapters.
无论推理使用 Llama 还是 Qwen，QVeris 都通过 Discover → Inspect → 调用提供治理化外部 API、工具、服务与实时数据访问。工具凭证与执行证据应和模型适配器分离。
