Types ¶
type Client ¶
type Client struct {
// contains filtered or unexported fields
}
Client implements the LLMProvider interface for AWS Bedrock.
func (*Client) Chat ¶
func (c *Client) Chat(ctx context.Context, messages []llmtypes.Message, tools []shuttle.Tool) (*llmtypes.LLMResponse, error)
Chat sends a conversation to Bedrock and returns the response.
func (*Client) ChatConverse ¶
func (c *Client) ChatConverse(ctx context.Context, messages []llmtypes.Message, tools []shuttle.Tool) (*llmtypes.LLMResponse, error)
ChatConverse implements non-streaming using AWS Bedrock Converse API. This is the modern, unified API that properly handles tool use. This method is used when streaming is not needed or disabled.
func (*Client) ChatStream ¶
func (c *Client) ChatStream(ctx context.Context, messages []llmtypes.Message, tools []shuttle.Tool, tokenCallback llmtypes.TokenCallback) (*llmtypes.LLMResponse, error)
ChatStream is DISABLED due to bugs with document.NewLazyDocument causing empty tool inputs. The ConverseStream API cannot properly serialize tool schemas, resulting in all tool calls having empty parameters ({}). Use the non-streaming Chat() method instead.
type Config ¶
type Config struct {
// AWS Configuration
Region string // Required: AWS region (e.g., us-east-1, us-west-2)
AccessKeyID string // Optional: if not using IAM role/profile
SecretAccessKey string // Optional: if not using IAM role/profile
SessionToken string // Optional: for temporary credentials
Profile string // Optional: AWS profile name from ~/.aws/config
BearerToken string // Optional: bearer token for IAM Identity Center / SSO auth (bypasses SigV4)
// Model Configuration
ModelID string // Default: us.anthropic.claude-sonnet-4-5-20250929-v1:0
MaxTokens int // Default: 4096
Temperature float64 // Default: 1.0
// Rate Limiting Configuration
RateLimiterConfig llm.RateLimiterConfig // Optional: rate limiting config (enables automatic throttle handling)
}
Config holds configuration for the Bedrock client.
type SDKClient ¶
type SDKClient struct {
// contains filtered or unexported fields
}
SDKClient implements the LLMProvider interface using the official Anthropic SDK for Bedrock. This is simpler and better maintained than the direct AWS SDK approach.
func NewSDKClient ¶
NewSDKClient creates a new Bedrock client using the Anthropic SDK.
func (*SDKClient) Chat ¶
func (c *SDKClient) Chat(ctx context.Context, messages []llmtypes.Message, tools []shuttle.Tool) (*llmtypes.LLMResponse, error)
Chat sends a conversation to Bedrock using the Anthropic SDK and returns the response.
func (*SDKClient) ChatStream ¶
func (c *SDKClient) ChatStream(ctx context.Context, messages []llmtypes.Message, tools []shuttle.Tool, tokenCallback llmtypes.TokenCallback) (*llmtypes.LLMResponse, error)
ChatStream streams tokens as they're generated from Bedrock using the Anthropic SDK.
