Instance Attribute Details

#content ⇒ Array<Anthropic::Models::TextBlock, Anthropic::Models::ThinkingBlock, Anthropic::Models::RedactedThinkingBlock, Anthropic::Models::ToolUseBlock, Anthropic::Models::ServerToolUseBlock, Anthropic::Models::WebSearchToolResultBlock>

Content generated by the model.

This is an array of content blocks, each of which has a ‘type` that determines its shape.

Example:

“‘json

{ “type”: “text”, “text”: “Hi, I’m Claude.” }

“‘

If the request input ‘messages` ended with an `assistant` turn, then the response `content` will continue directly from that last turn. You can use this to constrain the model’s output.

For example, if the input ‘messages` were:

“‘json [

{
  "role": "user",
  "content": "What's the Greek name for Sun? (A) Sol (B) Helios (C) Sun"
},
{ "role": "assistant", "content": "The best answer is (" }

] “‘

Then the response ‘content` might be:

“‘json

{ “type”: “text”, “text”: “B)” }

“‘

Returns:

# File 'lib/anthropic/models/message.rb', line 52

required :content, -> { Anthropic::Internal::Type::ArrayOf[union: Anthropic::ContentBlock] }

#id ⇒ String

Unique object identifier.

The format and length of IDs may change over time.

Returns:

  • (String) 


15
 
# File 'lib/anthropic/models/message.rb', line 15

required :id, String

#model ⇒ Symbol, ...

The model that will complete your prompt.nnSee [models](docs.anthropic.com/en/docs/models-overview) for additional details and options.

Returns:



60
 
# File 'lib/anthropic/models/message.rb', line 60

required :model, union: -> { Anthropic::Model }

#role ⇒ Symbol, :assistant

Conversational role of the generated message.

This will always be ‘“assistant”`.

Returns:

  • (Symbol, :assistant) 


68
 
# File 'lib/anthropic/models/message.rb', line 68

required :role, const: :assistant

#stop_reason ⇒ Symbol, ...

The reason that we stopped.

This may be one the following values:

  • ‘“end_turn”`: the model reached a natural stopping point

  • ‘“max_tokens”`: we exceeded the requested `max_tokens` or the model’s maximum

  • ‘“stop_sequence”`: one of your provided custom `stop_sequences` was generated

  • ‘“tool_use”`: the model invoked one or more tools

  • ‘“pause_turn”`: we paused a long-running turn. You may provide the response back as-is in a subsequent request to let the model continue.

  • ‘“refusal”`: when streaming classifiers intervene to handle potential policy violations

In non-streaming mode this value is always non-null. In streaming mode, it is null in the ‘message_start` event and non-null otherwise.

Returns:



88
 
# File 'lib/anthropic/models/message.rb', line 88

required :stop_reason, enum: -> { Anthropic::StopReason }, nil?: true

#stop_sequence ⇒ String?

Which custom stop sequence was generated, if any.

This value will be a non-null string if one of your custom stop sequences was generated.

Returns:

  • (String, nil) 


97
 
# File 'lib/anthropic/models/message.rb', line 97

required :stop_sequence, String, nil?: true

#type ⇒ Symbol, :message

Object type.

For Messages, this is always ‘“message”`.

Returns:

  • (Symbol, :message) 


105
 
# File 'lib/anthropic/models/message.rb', line 105

required :type, const: :message

#usage ⇒ Anthropic::Models::Usage

Billing and rate-limit usage.

Anthropic’s API bills and rate-limits by token counts, as tokens represent the underlying cost to our systems.

Under the hood, the API transforms requests into a format suitable for the model. The model’s output then goes through a parsing stage before becoming an API response. As a result, the token counts in ‘usage` will not match one-to-one with the exact visible content of an API request or response.

For example, ‘output_tokens` will be non-zero, even for an empty string response from Claude.

Total input tokens in a request is the summation of ‘input_tokens`, `cache_creation_input_tokens`, and `cache_read_input_tokens`.

Returns:
