+`service`::
+(Required, string)
+The type of service supported for the specified task type. In this case,
+`anthropic`.

+(Required, object)

+These settings are specific to the `anthropic` service.

+
+`api_key`:::
+(Required, string)
+A valid API key for the Anthropic API.
+
+`model_id`:::
+(Required, string)
+The name of the model to use for the {infer} task.
+You can find the supported models at https://docs.anthropic.com/en/docs/about-claude/models#model-names[Anthropic models].
+
+`rate_limit`:::
+(Optional, object)
+By default, the `anthropic` service sets the number of requests allowed per minute to `50`.
+This helps to minimize the number of rate limit errors returned from Anthropic.
+To modify this, set the `requests_per_minute` setting of this object in your service settings:

+.`task_settings` for the `completion` task type
+[%collapsible%closed]
+=====
+`max_tokens`:::
+(Required, integer)
+The maximum number of tokens to generate before stopping.
+
+`temperature`:::
+(Optional, float)
+The amount of randomness injected into the response.
++
+For more details about the supported range, see the https://docs.anthropic.com/en/api/messages[Anthropic messages API].
+
+`top_k`:::
+(Optional, integer)
+Specifies to only sample from the top K options for each subsequent token.
++
+Recommended for advanced use cases only. You usually only need to use `temperature`.
++
+For more details, see the https://docs.anthropic.com/en/api/messages[Anthropic messages API].
+
+`top_p`:::
+(Optional, float)
+Specifies to use Anthropic's nucleus sampling.
++
+In nucleus sampling, Anthropic computes the cumulative distribution over all the options for each subsequent token in decreasing probability order and cut it off once it reaches a particular probability specified by `top_p`. You should either alter `temperature` or `top_p`, but not both.
++
+Recommended for advanced use cases only. You usually only need to use `temperature`.

+For more details, see the https://docs.anthropic.com/en/api/messages[Anthropic messages API].

+==== Anthropic service example
+
+The following example shows how to create an {infer} endpoint called
+`anthropic_completion` to perform a `completion` task type.
