Snowflake Cortex
透過 Mastra 的模型路由器存取 21 個 Snowflake Cortex 模型。系統會自動使用 SNOWFLAKE_CORTEX_PAT 環境變數完成身分驗證。 Configure SNOWFLAKE_ACCOUNT as well.
如需進一步了解，請參閱Snowflake Cortex 文件。
.env
SNOWFLAKE_ACCOUNT=your-value
SNOWFLAKE_CORTEX_PAT=your-api-key
src/mastra/agents/my-agent.ts
import { Agent } from '@mastra/core/agent'
const agent = new Agent({
id: 'my-agent',
name: 'My Agent',
instructions: 'You are a helpful assistant',
model: 'snowflake-cortex/claude-fable-5',
})
// Generate a response
const response = await agent.generate('Hello!')
// Stream a response
const stream = await agent.stream('Tell me a story')
for await (const chunk of stream) {
console.log(chunk)
}
資訊
Mastra 使用與 OpenAI 相容的 /chat/completions endpoint。部分 Provider 特有功能可能無法使用，詳情請參閱Snowflake Cortex 文件。
