…, dynamic-filtering web search - ThinkingLevelMapper sets display="summarized" so adaptive-thinking summaries stream; the API default "omitted" returns empty thinking blocks on Opus 4.8 / Sonnet 5 / 4.7. - claude-haiku-4-5 THINKING_BUDGET floor -1 -> 1024: haiku has no dynamic thinking mode, and the -1 -> "auto" translation raised ConstraintViolationError against the numeric Range. - Select web_search_20260209 (dynamic filtering) for models that support it, basic web_search_20250305 otherwise; the supported-model list lives in the anthropic catalog.

What
Three Anthropic text improvements:
Stream thinking summaries.
ThinkingLevelMappernow emitsthinking: {type: "adaptive", display: "summarized"}. On Opus 4.8 / Sonnet 5 / Opus 4.7 the API defaultsdisplayto"omitted", which streams thinking blocks with empty text (nothinking_deltaevents) — so adaptive-thinking summaries never surfaced to callers that stream reasoning.Fix haiku thinking budget.
claude-haiku-4-5THINKING_BUDGETfloor-1 → 1024. Haiku 4.5 has no dynamic/adaptive thinking mode (only a fixedbudget_tokens, min 1024); the-1 → "auto"translation was then re-validated against the numericRangeand raisedConstraintViolationError: "Must be numeric, got str"at request build.Dynamic-filtering web search. Select
web_search_20260209(dynamic filtering) for models that support it (Opus 4.6+ / Sonnet 4.6+ / Fable 5), basicweb_search_20250305otherwise. The supported-model list lives in the Anthropic text catalog (DYNAMIC_FILTERING_MODELS); a plain conditional in the textToolsMapperpicks the version. No model IDs in the mapper, nothing added to core.Verification
ruff+mypy(344 files) clean; unit tests pass.web_search_20260209streams interleaved reasoning with populated grounding on supporting models (note: dynamic filtering runs search inside code execution, so inlineweb_search_result_locationcitations are not emitted on those turns — an API behavior, not a regression here).🤖 Generated with Claude Code
