This page is larger than the 256 KiB this site keeps, so one side of the diff below stops where the stored text does.
The two sides of this change are more than 400 edits apart, too far apart to line up, so this is the differ's own diff of it and the words inside a line are not marked.

6748 `thinking_dropped` — a `thinking`, `redacted_thinking` or `connector_text`
6749 block from the request's `messages` that was removed from the prompt instead
6750 of being shown to the model because it failed a binding check. More entry
6751 types may be added over time; ignore types you do not recognize.
6937 - `input_transformations: optional array of BetaInputTransformation or null`
6938
6939 Changes the API made to the request's input before showing it to the model,
6940 and blocks that failed a binding check but were left unchanged: one entry per
6941 block, in request order. Two entry types today. `thinking_dropped` — a
6942 `thinking`, `redacted_thinking` or `connector_text` block from the request's
6943 `messages` that was removed from the prompt instead of being shown to the
6944 model because it failed a binding check. `thinking_mismatch_allowed` — a
6945 `thinking` or `redacted_thinking` block that failed the conversation check
6946 (the conversation before it differs from the one it was created in, or it
6947 carries no record of one on a model that requires it) and was shown to the
6948 model all the same, because that check is not enforced for this request.
6949 More entry types may be added over time; ignore types you do not recognize.
67526950
67536951 Requires `anthropic-beta: thinking-binding-controls-2026-08-01`. Present on
67546952 every such response from a model that supports extended thinking, as `[]`
6755 when nothing was changed; without the beta, blocks are removed all the same
6756 but nothing is reported. Removed blocks contribute nothing to
6757 `usage.input_tokens`. When streaming, the array is final in `message_start`;
6758 the final `message_delta` event carries it only when a server-side model
6759 fallback happened mid-stream, in which case it holds the serving model's
6760 entries and replaces the one in `message_start`.
6761

6769
6770 Where the removed block was in your request, as `messages.{i}.content.{j}`:
6771 `i` indexes the `messages` array you sent and `j` that message's `content`
6772 array — the same form error messages use.
6773
6774 - `reason: "model_binding_mismatch" or "prefix_binding_mismatch" or "organization_binding_mismatch" or "end_user_binding_mismatch"`
6775
6776 Which binding check removed the block: `model_binding_mismatch` — it was
6777 created by a model whose reasoning the requested model may not read;
6778 `prefix_binding_mismatch` — the conversation before it differs from the
6779 conversation it was created in (the rest of that turn's consecutive thinking
6780 blocks are removed with it, each with this reason);
6781 `organization_binding_mismatch` — it was created under a different
6782 organization (an Anthropic organization, AWS account or Google Cloud project)
6783 and this organization is not one of its additional organizations;
6784 `end_user_binding_mismatch` — it was created for a different end user, or
6785 was removed by the consumer-organization binding. A block that would fail
6786 several checks reports one reason, in this order of precedence:
6787 `organization_binding_mismatch`, `end_user_binding_mismatch`,
6788 `model_binding_mismatch`, `prefix_binding_mismatch`.

6834 Billing and rate-limit usage.
6835
6836 Anthropic's API bills and rate-limits by token counts, as tokens represent the underlying cost to our systems.
6837
6838 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.
6839
6840 For example, `output_tokens` will be non-zero, even for an empty string response from Claude.
6841
6842 Total input tokens in a request is the summation of `input_tokens`, `cache_creation_input_tokens`, and `cache_read_input_tokens`.

6866 - `iterations: BetaIterationsUsage or null`
6867
6868 Per-iteration token usage breakdown.
6869
6870 Each entry represents one sampling iteration, with its own input/output token counts and cache statistics, discriminated by `type`. For `message` entries (model sampling iterations, such as the turns of a server-side tool use loop), this allows you to:
6871
6872 - Determine which iterations exceeded long context thresholds (>=200k tokens)
6873 - Calculate the context window size from the last `message` entry
6874 - Understand token accumulation across server-side tool use loops
6875
6876 A `compaction` entry reports the token usage of the compaction operation itself — the server-side request that summarizes the context being closed — NOT the size of the context that was compacted away, and its token counts can be much smaller than that closed context (for example, a compaction that closes a ~200k-token context can report only a few thousand tokens). Do not derive the context window size from a `compaction` entry, even when it is the last entry. A `compaction` entry's tokens are not included in the top-level `usage` fields. When an input-token trigger is in effect (the default — 150,000 tokens unless configured otherwise), each `compaction` entry closes a context that had reached at least that threshold, though the context can exceed it by the final iteration's output and tool results.

6899 `thinking_dropped` — a `thinking`, `redacted_thinking` or `connector_text`
6900 block from the request's `messages` that was removed from the prompt instead
6901 of being shown to the model because it failed a binding check. More entry
6902 types may be added over time; ignore types you do not recognize.

6906 when nothing was changed; without the beta, blocks are removed all the same
6907 but nothing is reported. Removed blocks contribute nothing to
6908 `usage.input_tokens`. When streaming, the array is final in `message_start`;
6909 the final `message_delta` event carries it only when a server-side model
6910 fallback happened mid-stream, in which case it holds the serving model's
6911 entries and replaces the one in `message_start`.
6953 when there is no entry to report; without the beta, blocks are removed or
6954 left in place all the same but nothing is reported. Removed blocks contribute
6955 nothing to `usage.input_tokens`; blocks left in place count as sent. When

7018 carries no record of one on a model that requires it. Were the check
7019 enforced for this request, the block would have been removed or the request
7020 rejected (`thinking.block_binding.prefix_mismatch_behavior`). A removal also
7021 takes the rest of that turn's consecutive thinking blocks, whereas here each
7022 block is checked on its own, so `thinking_mismatch_allowed` entries are a
7023 lower bound on what enforcement would remove.

18451 (the conversation before it differs from the one it was created in, or it
18452 carries no record of one on a model that requires it) and was shown to the

18520 Which binding check the block failed; the block was shown to the model all
18521 the same. Always `prefix_binding_mismatch` today — the conversation before
18522 the block differs from the conversation it was created in, or the block
18523 carries no record of one on a model that requires it. Were the check
18524 enforced for this request, the block would have been removed or the request
18525 rejected (`thinking.block_binding.prefix_mismatch_behavior`). A removal also
18526 takes the rest of that turn's consecutive thinking blocks, whereas here each
18527 block is checked on its own, so `thinking_mismatch_allowed` entries are a
18528 lower bound on what enforcement would remove.

5614 block from the request's `messages` that was removed from the prompt instead
5615 of being shown to the model because it failed a binding check. More entry
5616 types may be added over time; ignore types you do not recognize.

5758 Changes the API made to the request's input before showing it to the model,

5761 `thinking`, `redacted_thinking` or `connector_text` block from the request's
5762 `messages` that was removed from the prompt instead of being shown to the

56195771 every such response from a model that supports extended thinking, as `[]`
5620 when nothing was changed; without the beta, blocks are removed all the same
5621 but nothing is reported. Removed blocks contribute nothing to
5622 `usage.input_tokens`. When streaming, the array is final in `message_start`;
5623 the final `message_delta` event carries it only when a server-side model

5642 created by a model whose reasoning the requested model may not read;
5643 `prefix_binding_mismatch` — the conversation before it differs from the
5644 conversation it was created in (the rest of that turn's consecutive thinking
5645 blocks are removed with it, each with this reason);
5646 `organization_binding_mismatch` — it was created under a different
5647 organization (an Anthropic organization, AWS account or Google Cloud project)
5648 and this organization is not one of its additional organizations;
5649 `end_user_binding_mismatch` — it was created for a different end user, or
5650 was removed by the consumer-organization binding. A block that would fail
5651 several checks reports one reason, in this order of precedence:

5700
5701 Anthropic's API bills and rate-limits by token counts, as tokens represent the underlying cost to our systems.
5702
5703 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.
5704
5705 For example, `output_tokens` will be non-zero, even for an empty string response from Claude.
5706
5707 Total input tokens in a request is the summation of `input_tokens`, `cache_creation_input_tokens`, and `cache_read_input_tokens`.
5708

5728
5729 minimum: 0
5730
5731 - `iterations: BetaIterationsUsage or null`
5732
5733 Per-iteration token usage breakdown.
5734
5735 Each entry represents one sampling iteration, with its own input/output token counts and cache statistics, discriminated by `type`. For `message` entries (model sampling iterations, such as the turns of a server-side tool use loop), this allows you to:
5736
5737 - Determine which iterations exceeded long context thresholds (>=200k tokens)
5738 - Calculate the context window size from the last `message` entry
5739 - Understand token accumulation across server-side tool use loops
5740
5741 A `compaction` entry reports the token usage of the compaction operation itself — the server-side request that summarizes the context being closed — NOT the size of the context that was compacted away, and its token counts can be much smaller than that closed context (for example, a compaction that closes a ~200k-token context can report only a few thousand tokens). Do not derive the context window size from a `compaction` entry, even when it is the last entry. A `compaction` entry's tokens are not included in the top-level `usage` fields. When an input-token trigger is in effect (the default — 150,000 tokens unless configured otherwise), each `compaction` entry closes a context that had reached at least that threshold, though the context can exceed it by the final iteration's output and tool results.
5742

5750
5751 `output_tokens` remains the inclusive, authoritative total used for billing.
5752 This object provides a read-only decomposition for observability — for example,
5753 how many of the billed output tokens were spent on internal reasoning that may
5754 have been summarized before being returned to you.

5762 Changes the API made to the request's input before showing it to the model:
5763 one entry per change, in request order. Today the only entry type is
5764 `thinking_dropped` — a `thinking`, `redacted_thinking` or `connector_text`
5765 block from the request's `messages` that was removed from the prompt instead
5766 of being shown to the model because it failed a binding check. More entry
5767 types may be added over time; ignore types you do not recognize.

5840 takes the rest of that turn's consecutive thinking blocks, whereas here each

29651 `thinking` or `redacted_thinking` block that failed the conversation check
29652 (the conversation before it differs from the one it was created in, or it
29653 carries no record of one on a model that requires it) and was shown to the
29654 model all the same, because that check is not enforced for this request.

2903129656
2903229657 Requires `anthropic-beta: thinking-binding-controls-2026-08-01`. Present on
2903329658 every such response from a model that supports extended thinking, as `[]`
29034 when nothing was changed; without the beta, blocks are removed all the same
29035 but nothing is reported. Removed blocks contribute nothing to
29036 `usage.input_tokens`. When streaming, the array is final in `message_start`;
29037 the final `message_delta` event carries it only when a server-side model
29038 fallback happened mid-stream, in which case it holds the serving model's
29039 entries and replaces the one in `message_start`.

29047 - `path: string`
29048
29049 Where the removed block was in your request, as `messages.{i}.content.{j}`:
29050 `i` indexes the `messages` array you sent and `j` that message's `content`
29051 array — the same form error messages use.
29052
29053 - `reason: "model_binding_mismatch" or "prefix_binding_mismatch" or "organization_binding_mismatch" or "end_user_binding_mismatch"`
29054
29055 Which binding check removed the block: `model_binding_mismatch` — it was
29056 created by a model whose reasoning the requested model may not read;
29057 `prefix_binding_mismatch` — the conversation before it differs from the
29058 conversation it was created in (the rest of that turn's consecutive thinking
29059 blocks are removed with it, each with this reason);
29060 `organization_binding_mismatch` — it was created under a different
29061 organization (an Anthropic organization, AWS account or Google Cloud project)
29062 and this organization is not one of its additional organizations;
29063 `end_user_binding_mismatch` — it was created for a different end user, or
29064 was removed by the consumer-organization binding. A block that would fail
29065 several checks reports one reason, in this order of precedence:
29066 `organization_binding_mismatch`, `end_user_binding_mismatch`,
29067 `model_binding_mismatch`, `prefix_binding_mismatch`.
29659 when there is no entry to report; without the beta, blocks are removed or
29660 left in place all the same but nothing is reported. Removed blocks contribute
29661 nothing to `usage.input_tokens`; blocks left in place count as sent. When
29662 streaming, the array is final in `message_start`; the final `message_delta`
29663 event carries it only when a server-side model fallback happened mid-stream,
29664 in which case it holds the serving model's entries and replaces the one in
29665 `message_start`.

30947 alone, that a later request sends back first in `messages`, in place of

30949 the parameter compacts, and nothing is sampled after the block.

32153 Which binding check the block failed; the block was shown to the model all
32154 the same. Always `prefix_binding_mismatch` today — the conversation before
32155 the block differs from the conversation it was created in, or the block
32156 carries no record of one on a model that requires it. Were the check
32157 enforced for this request, the block would have been removed or the request
32158 rejected (`thinking.block_binding.prefix_mismatch_behavior`). A removal also
32159 takes the rest of that turn's consecutive thinking blocks, whereas here each
32160 block is checked on its own, so `thinking_mismatch_allowed` entries are a
32161 lower bound on what enforcement would remove.

44403 of being shown to the model because it failed a binding check. More entry
44404 types may be added over time; ignore types you do not recognize.

45848
45849 Changes the API made to the request's input before showing it to the model,
45850 and blocks that failed a binding check but were left unchanged: one entry per
45851 block, in request order. Two entry types today. `thinking_dropped` — a
45852 `thinking`, `redacted_thinking` or `connector_text` block from the request's
45853 `messages` that was removed from the prompt instead of being shown to the
45854 model because it failed a binding check. `thinking_mismatch_allowed` — a
45855 `thinking` or `redacted_thinking` block that failed the conversation check
45856 (the conversation before it differs from the one it was created in, or it
45857 carries no record of one on a model that requires it) and was shown to the
45858 model all the same, because that check is not enforced for this request.
45859 More entry types may be added over time; ignore types you do not recognize.
4440545860
4440645861 Requires `anthropic-beta: thinking-binding-controls-2026-08-01`. Present on
4440745862 every such response from a model that supports extended thinking, as `[]`
44408 when nothing was changed; without the beta, blocks are removed all the same
44409 but nothing is reported. Removed blocks contribute nothing to
44410 `usage.input_tokens`. When streaming, the array is final in `message_start`;
44411 the final `message_delta` event carries it only when a server-side model
44412 fallback happened mid-stream, in which case it holds the serving model's
44413 entries and replaces the one in `message_start`.

44432 conversation it was created in (the rest of that turn's consecutive thinking
44433 blocks are removed with it, each with this reason);
44434 `organization_binding_mismatch` — it was created under a different
44435 organization (an Anthropic organization, AWS account or Google Cloud project)
44436 and this organization is not one of its additional organizations;
44437 `end_user_binding_mismatch` — it was created for a different end user, or
44438 was removed by the consumer-organization binding. A block that would fail
44439 several checks reports one reason, in this order of precedence:
44440 `organization_binding_mismatch`, `end_user_binding_mismatch`,

45929 enforced for this request, the block would have been removed or the request
45930 rejected (`thinking.block_binding.prefix_mismatch_behavior`). A removal also
45931 takes the rest of that turn's consecutive thinking blocks, whereas here each
45932 block is checked on its own, so `thinking_mismatch_allowed` entries are a
45933 lower bound on what enforcement would remove.

1812 Changes the API made to the request's input before showing it to the model:
1813 one entry per change, in request order. Today the only entry type is
1814 `thinking_dropped` — a `thinking`, `redacted_thinking` or `connector_text`
1815 block from the request's `messages` that was removed from the prompt instead
1816 of being shown to the model because it failed a binding check. More entry
1817 types may be added over time; ignore types you do not recognize.
1818 Changes the API made to the request's input before showing it to the model,
1819 and blocks that failed a binding check but were left unchanged: one entry per
1820 block, in request order. Two entry types today. `thinking_dropped` — a
1821 `thinking`, `redacted_thinking` or `connector_text` block from the request's
1822 `messages` that was removed from the prompt instead of being shown to the
1823 model because it failed a binding check. `thinking_mismatch_allowed` — a
1824 `thinking` or `redacted_thinking` block that failed the conversation check
1825 (the conversation before it differs from the one it was created in, or it
1826 carries no record of one on a model that requires it) and was shown to the
1827 model all the same, because that check is not enforced for this request.
1828 More entry types may be added over time; ignore types you do not recognize.

18191830 Requires `anthropic-beta: thinking-binding-controls-2026-08-01`. Present on
18201831 every such response from a model that supports extended thinking, as `[]`
1821 when nothing was changed; without the beta, blocks are removed all the same
1822 but nothing is reported. Removed blocks contribute nothing to
1823 `usage.input_tokens`. When streaming, the array is final in `message_start`;
1824 the final `message_delta` event carries it only when a server-side model
1825 fallback happened mid-stream, in which case it holds the serving model's
1826 entries and replaces the one in `message_start`.
1832 when there is no entry to report; without the beta, blocks are removed or
1833 left in place all the same but nothing is reported. Removed blocks contribute
1834 nothing to `usage.input_tokens`; blocks left in place count as sent. When

1898 enforced for this request, the block would have been removed or the request
1899 rejected (`thinking.block_binding.prefix_mismatch_behavior`). A removal also
1900 takes the rest of that turn's consecutive thinking blocks, whereas here each

5764 carries no record of one on a model that requires it) and was shown to the

10545**GET** `/v1/organizations/compliance_settings`
10546
10547Retrieve your organization's Compliance Settings.
10548
10549Compliance Settings is a singleton resource: there is exactly one per
10550organization, addressed without an identifier. The `state` field reflects
10551whether the Compliance API is enabled. An organization with a parent
10552organization reads the state inherited from the parent's configuration.
