Short answer: there isn’t a “Claude Opus 4.8” model. The flagship model is Claude 3 Opus (model ID: claude-3-opus-20240229). Below is how to call it via the Anthropic Messages API. Prerequisites - Create an Anthropic account and API key: https://console.anthropic.com - Keep the base URL and headers handy: - URL: https://api.anthropic.com/v1/messages - Headers: - x-api-key: YOUR_API_KEY - content-type: application/json - anthropic-version: 2023-06-01 Quick start (cURL) curl https://api.anthropic.com/v1/messages \ -H "x-api-key: $ANTHROPIC_API_KEY" \ -H "content-type: application/json" \ -H "anthropic-version: 2023-06-01" \ -d '{ "model": "claude-3-opus-20240229", "max_tokens": 1024, "messages": [ {"role": "user", "content": "Give me a 3-bullet summary of the benefits of serverless."} ] }' Node.js (official SDK) import Anthropic from "@anthropic-ai/sdk"; const anthropic = new Anthropic({ apiKey: process.env.ANTHROPIC_API_KEY }); const msg = await anthropic.messages.create({ model: "claude-3-opus-20240229", max_tokens: 1024, messages: [{ role: "user", content: "Write a haiku about the sea." }], }); console.log(msg.content[0].text); Python (official SDK) from anthropic import Anthropic import os client = Anthropic(api_key=os.environ["ANTHROPIC_API_KEY"]) message = client.messages.create( model="claude-3-opus-20240229", max_tokens=1024, messages=[{"role": "user", "content": "Draft a friendly welcome email in 3 sentences."}] ) print(message.content[0].text) Streaming (server-sent events via cURL) curl -N https://api.anthropic.com/v1/messages \ -H "x-api-key: $ANTHROPIC_API_KEY" \ -H "content-type: application/json" \ -H "anthropic-version: 2023-06-01" \ -H "accept: text/event-stream" \ -d '{ "model": "claude-3-opus-20240229", "max_tokens": 1024, "stream": true, "messages": [{"role":"user","content":"Explain transformers in 5 short points."}] }' Useful options - system: Optional system prompt to set behavior. - temperature: 0–1 (lower = more deterministic). - top_p, top_k: Sampling controls (optional). - max_tokens: Required upper bound for output length. Common errors - 401 Unauthorized: Check x-api-key and account status. - 400 Bad Request: Verify JSON shape, model name, and required params (model, messages, max_tokens). - 429 Rate limit: Back off and retry with exponential delay. Notes - If you’re using AWS Bedrock or Google Cloud Vertex AI, use their SDKs and provider-specific model IDs for Claude 3 Opus; headers/endpoints differ. - For the exact, current model IDs and features, see Anthropic’s model list in the docs/console. If you actually meant a different provider or a specific SDK (e.g., OpenRouter, Bedrock, Vertex), tell me which one and I’ll tailor the example.

Sådan bruger du Deepseek V4 API

For udviklere er den kombination vigtig af én simpel grund: den reducerer friktionen ved migrering, samtidig med at den hæver loftet for, hvad du kan bygge. Du behøver ikke at lære en helt ny API-form. Du opdaterer modelnavnet, bevarer base-URL'en og udruller med et større kontekstvindue og nyere ræsonneringsadfærd. DeepSeeks officielle dokumentation siger udtrykkeligt, at du skal beholde base-URL'en og ændre modelparameteren til deepseek-v4-pro eller deepseek-v4-flash.
