Claude Opus 4.6 Support

Added support for Anthropic's latest Claude Opus 4.6 model, bringing enhanced reasoning capabilities and improved performance to your applications.

Model ID: anthropic.claude-opus-4-6-v1

Key Capabilities:

• Extended context window: 200,000 tokens
• Maximum output: 128,000 tokens
• Advanced reasoning with up to 8,191 reasoning tokens
• Full support for vision, document processing, and tool use
• Compatible with Converse API (streaming and non-streaming)
• Global cross-region inference support

Usage Example

Basic Conversation with Claude Opus 4.6

import BedrockService
import Logging

// Initialize the Bedrock service
let bedrock = try await BedrockService(
    region: .useast1,
    logger: Logger(label: "MyApp")
)

// Use the new Claude Opus 4.6 model
let model: BedrockModel = .claude_opus_v4_6

// Create a conversation request
let builder = try ConverseRequestBuilder(with: model)
    .withPrompt("Explain quantum entanglement in simple terms")
    .withTemperature(0.7)
    .withMaxTokens(2048)

// Send the request and get the response
let reply = try await bedrock.converse(with: builder)
print("Assistant: \(reply)")

Multi-turn Conversation

// Continue the conversation
let followUp = try ConverseRequestBuilder(from: builder, with: reply)
    .withPrompt("Can you provide a real-world analogy?")

let secondReply = try await bedrock.converse(with: followUp)
print("Assistant: \(secondReply)")

Using Advanced Reasoning

// Leverage Claude Opus 4.6's reasoning capabilities
let reasoningBuilder = try ConverseRequestBuilder(with: .claude_opus_v4_6)
    .withPrompt("Solve this complex problem step by step: ...")
    .withMaxTokens(8192)
    // The model will automatically use reasoning tokens as needed

let solution = try await bedrock.converse(with: reasoningBuilder)
print("Solution: \(solution)")

Streaming Responses

// Stream responses for real-time output
let streamBuilder = try ConverseRequestBuilder(with: .claude_opus_v4_6)
    .withPrompt("Write a detailed explanation of machine learning")

for try await chunk in bedrock.converseStream(with: streamBuilder) {
    if let text = chunk.text {
        print(text, terminator: "")
    }
}
