Amazon Bedrock model IDs shows the model IDs. Below is a copy of the Anthropic models as of this answer. There is only one Claude 2.1 available (anthropic.claude-v2:1). From https://aws.amazon.com/bedrock/claude/ we see this is the one "with a 200K token context window".
| Provider | Model name | Version | Model ID |
|---|---|---|---|
| Anthropic | Claude | 2.0 | anthropic.claude-v2 |
| Anthropic | Claude | 2.1 | anthropic.claude-v2:1 |
| Anthropic | Claude 3 Sonnet | 1.0 | anthropic.claude-3-sonnet-20240229-v1:0 |
| Anthropic | Claude 3 Haiku | 1.0 | anthropic.claude-3-haiku-20240307-v1:0 |
| Anthropic | Claude Instant | 1.x | anthropic.claude-instant-v1 |
The Anthropic Claude Text Completions API provides inference parameters, including max_tokens_to_sample (maximum number of tokens to generate before stopping). There is no parameter for input tokens / context window, since you control that via the prompt parameter.

Thanks! Do you know why the text completions API doesn't support Claude 3?
Claude 3 uses the Messages API (see https://docs.aws.amazon.com/bedrock/latest/userguide/model-parameters-anthropic-claude-messages.html)
