-Bucket Boundaries
------------------
-
-This section describes the explicit bucket boundaries for metrics such as token usage and operation duration, and guides users to create Views to implement them according to the semantic conventions.
-
-The bucket boundaries are defined as follows:
-
-- For `gen_ai.client.token.usage`: [1, 4, 16, 64, 256, 1024, 4096, 16384, 65536, 262144, 1048576, 4194304, 16777216, 67108864]
-- For `gen_ai.client.operation.duration`: [0.01, 0.02, 0.04, 0.08, 0.16, 0.32, 0.64, 1.28, 2.56, 5.12, 10.24, 20.48, 40.96, 81.92]
-
-To implement these bucket boundaries, you can create Views in your OpenTelemetry SDK setup. Here is an example:
-
-.. code-block:: python
-
-    from opentelemetry.sdk.metrics import MeterProvider, View
-    from opentelemetry.sdk.metrics.export import PeriodicExportingMetricReader
-    from opentelemetry.exporter.otlp.proto.grpc.metric_exporter import OTLPMetricExporter
-    from opentelemetry.sdk.metrics.aggregation import ExplicitBucketHistogramAggregation
-
-    views = [
-        View(
-            instrument_name="gen_ai.client.token.usage",
-            aggregation=ExplicitBucketHistogramAggregation([1, 4, 16, 64, 256, 1024, 4096, 16384, 65536, 262144, 1048576, 4194304, 16777216, 67108864]),
-        ),
-        View(
-            instrument_name="gen_ai.client.operation.duration",
-            aggregation=ExplicitBucketHistogramAggregation([0.01, 0.02, 0.04, 0.08, 0.16, 0.32, 0.64, 1.28, 2.56, 5.12, 10.24, 20.48, 40.96, 81.92]),
-        ),
-    ]
-
-    metric_exporter = OTLPMetricExporter(endpoint="http://localhost:4317")
-    metric_reader = PeriodicExportingMetricReader(metric_exporter)
-    provider = MeterProvider(
-        metric_readers=[metric_reader],
-        views=views
-    )
-
-    from opentelemetry.sdk.metrics import set_meter_provider
-    set_meter_provider(provider)
-
