Developer — Amazon Bedrock Wins
| Feature | Grok | Amazon Bedrock |
|---|---|---|
Function Calling | Yes. The xAI API supports function calling: you define custom tools and Grok returns tool-call requests for your app to execute, alongside built-in tools such as web search, X search, and code interpreter. | Yes, requires plus plan. Bedrock Agents use tool/action groups for function calling. |
Streaming Responses | Yes. The xAI API streams Grok text output over Server-Sent Events. Set stream: true on chat completions; all text-capable Grok models support it, including grok-4.6. | Yes, requires plus plan. InvokeModelWithResponseStream and Converse stream tokens. |
Fine-Tuning | No | Yes, requires plus plan. Custom model fine-tuning is a listed Bedrock capability. |
Embeddings API | No | Yes, requires plus plan. Titan Embeddings and Knowledge Base vector indexes. |
Structured Output (JSON) | No | Partial. Tool schemas and JSON mode depend on the model. Guardrails add structure. |
Reasoning / Thinking Mode | Yes. Auto populated | Partial. Reasoning models (e.g. Claude extended thinking) can be hosted. No Bedrock-branded Deep Think toggle. |
Local Execution | No. Managed AWS inference. Distinct from Kiro local dev. | |
Open Weights | Partial. Hosts some open models (e.g. Llama) alongside proprietary FMs. | |
Multi-Agent Orchestration | Yes. Four-agent backend | Yes, requires plus plan. AgentCore supports multi-agent workflows and supervisor patterns. |
