If the configured model doesn't support the chosen mode, the API rejects the request with a 400 — owners/admins see the raw error, regular users get the generic fallback.

 | `thinking_display` | string | *(omitted)* | `"summarized"` or `"omitted"`. Only valid together with `"thinking": "adaptive"`. Controls whether the API returns a readable summary of the reasoning (logged, never sent to chat). Thinking is billed the same either way; when omitted, the API's per-model default applies. |
-| `effort`           | string | *(omitted)* | `"low"`, `"medium"`, `"high"`, `"xhigh"` or `"max"`. Caps how much reasoning and token spend a turn may use; the API default is `high` on most models and `medium` on Haiku 5.5 and Opus 5.5. For short-reply chat bots `"low"` or `"medium"` cuts cost noticeably. Rejected with a 400 on models older than Claude 4.6 (Haiku 4.5, Sonnet 4.5) — omit it there. |

-| `cache_history`    | bool   | `true`      | Places a prompt-cache breakpoint on the trailing conversation block, so each turn reads the prior history from cache instead of reprocessing it at full price. Set `false` to cache only the system prompt. |
 | `web_search`       | object | *(omitted)* | Enables Anthropic's server-side web search (and, optionally, web fetch), sandboxed to a domain allowlist. Omit the key entirely to leave both tools off — an absent block sends byte-identical requests to before. See [Web search / fetch](#web-search--fetch) below. |
 
-Every reply logs one accounting line — `[usage] model=... in=... out=... thinking=... cache_read=... cache_write=... stop=...` — so thinking spend (billed even when its text is omitted) stays visible in `journalctl`/`docker compose logs`. A `stop=max_tokens` line is accompanied by an error-level warning that the reply was truncated.
-
-> [!TIP]
-> Watch `cache_read`/`cache_write` after changing prompts or models. A cache breakpoint below the model's minimum cacheable prefix fails **silently** — no error, just `cache_write=0` forever. The minimum is model-specific and not monotonic across generations (Haiku 4.5 needs 4096 tokens; Sonnet 4.6 needs 1024), so a short system prompt that caches fine on one model may never cache on another. Note also that chat memory is a sliding window: once it is full, each turn evicts the oldest message and changes the prefix, so `cache_read` on long-running chats will be lower than on fresh ones.
-
-### Coalescing rapid messages
-
-A user who sends "how do I do X", then "sorry typo", then "lmao" in five seconds would otherwise get three separate replies — the bot starts a full turn per message, because each Telegram update independently drives one. `debounce_ms` holds text messages in a per-chat buffer and resets the window on every new message, dispatching a single turn once the user stops typing.
-
-```json
-"debounce_ms": 2500
-```
-
-Reasonable windows are 1500–3000ms for ordinary chat and up to 8000ms for Telegram Business, where a person writing to a business account tends to send longer bursts. The maximum is 30000ms.
-
-Nothing is discarded while buffering. Each message is still persisted and added to chat memory the moment it arrives, so the single coalesced turn sees all of them — the buffer only decides *when* to answer, never *what* the model reads. Reply metadata (language, premium status, business connection) follows the most recent message in the batch.
-
-What deliberately does **not** wait:
-
-- **Commands** (`/stats`, `/clear`, …) dispatch immediately.
-- **Photos, albums, voice, and stickers** dispatch immediately and cancel any pending text window. The buffered text is not lost — it is already in memory, so the media turn answers it too.
-- **`/clear` and `/clear_hard`** cancel the buffer outright. Without this, the window would fire seconds after the wipe and replay the just-deleted messages back into memory.
-
-**Edits count as typing.** Mobile clients deliver autocorrect fixes as `edited_message` updates a few seconds after the send. The stored text (or photo caption) is replaced with the edit. If the message is still inside its quiet window, the window restarts. If a turn is already reading the old wording and has shown nothing yet, that turn restarts with the correction. An edit to a message that was already answered only corrects the record.
-
-#### Messages that arrive mid-turn
-
-No window catches every slow typist, and no LLM API lets you append to a request already in flight, so there is also a rule for a message that lands *after* the window closed, while the model is still working. At most one turn runs per chat, and a text flush that finds one running is handled in one of three ways:
-
-- **Dropped** if the running turn's context already includes the message. Its reply answers the new message too.
-- **Restarted** if nothing has been shown to the user yet. The running request is cancelled and rerun with the new message included. This is the only case that wastes tokens, and it is bounded by the time to first output; with `cache_history` on, the rerun reads the conversation prefix from cache.
-- **Collected** if output is already on screen. The message gets its own turn as soon as the running one finishes, instead of a second concurrent one. If the finished turn's context turns out to have included the message after all, the extra turn is skipped.
-
-Photos, voice, and stickers wait for a running turn to finish and are never restarted. Photo uploads still start immediately and overlap the running turn; only the model call queues behind it.
-
-While a turn is running the bot shows Telegram's "typing…" indicator (or "recording audio" while synthesising a voice reply), refreshed every 4 seconds because Telegram expires the status after 5. Without it, a debounce window reads as the bot ignoring you — which is what prompts users to send more messages in the first place.
-
-> [!NOTE]
-> A cancelled request is not free. Anthropic bills the input tokens and any output generated before the connection closed, and a web search the turn already ran is billed again on the rerun. That is why a restart only happens before anything was shown, and why a message that never dispatched is still the cheapest message of all.
-
-### Draft streaming and the Stop button
-
-```json
-"stream_drafts": true
-```
-
-With `stream_drafts` on, a reply in a private chat is streamed into one Telegram draft that grows in place (`sendMessageDraft`, available to every bot since Bot API 9.5), then sent as a single real message when the model finishes. Long replies split at 4096 characters. The draft is updated at most once per second, matching Telegram's per-chat send guidance, and re-sent every 10 seconds through silent stretches such as a web search so the preview does not expire.
-
-The draft carries Telegram's native **Stop** button (Bot API 10.3). Tapping it cancels the Anthropic stream; whatever the user had watched being written is sent as a normal message and stored in memory, so the next turn continues from the reply the user actually saw. A message the user sent before tapping Stop still gets its own turn afterwards. The draft text is capped at 4096 characters; the final message is split instead.
-
-What falls back to the previous one-message-per-text-block delivery:
-
-- **Business connections and group chats.** Telegram documents drafts for private chats only, and `sendMessageDraft` has no `business_connection_id` parameter.
-- **A rejected draft call.** After the first error the bot stops touching the draft and just sends the final message.
-
-> [!IMPORTANT]
-> While a draft is on screen, Telegram Android disables the composer: the user cannot send text or commands until the final message lands, and Telegram has said this is intended. The Stop button is their way out. For that reason the draft only appears once the model starts producing text; tool calls before that are covered by the typing indicator, which locks nothing. A March 2026 report described drafts rendering under "Pinned Messages" on iOS, so check the behaviour on your own client before enabling this for users.
+Every reply logs one accounting line — `[usage] model=... in=... out=... thinking=... stop=...` — so thinking spend (billed even when its text is omitted) stays visible in `journalctl`/`docker compose logs`. A `stop=max_tokens` line is accompanied by an error-level warning that the reply was truncated.

 **Search/fetch path asymmetry (important).** Anthropic filters the two tools differently: `web_search` honors a path prefix (`example.com/help` matches only `example.com/help/...`), but **`web_fetch` matches on the host only — an entry that includes a path never matches any fetch URL**. The engine bridges this: `web_search` gets your entries verbatim, while `web_fetch` gets the host portion of each entry (path stripped, deduped). So a path-scoped `allowed_domains` still permits fetching across the whole host. If that host isn't wholly trusted, list the fetchable hosts explicitly in `fetch_allowed_domains` instead.
 
@@ -180,8 +123,6 @@ The allowlist is a **hard, server-side sandbox**, not a prompt request — off-l
 
 `web_fetch` can only open a URL that a `web_search` result surfaced (or the user pasted) — never one the model invents or rebuilds from a page title; those return `url_not_in_prior_context`. So a fetch-enabled bot's prompt should steer it to **search first, then fetch a returned URL**, and to **re-search with a more specific query** (rather than guess a URL) when the exact page it wants isn't in the results.
 
-**Dynamic filtering.** The engine uses the `web_search_20260318` / `web_fetch_20260318` tools, which run the search inside Anthropic's code-execution sandbox and let the model discard irrelevant parts of a result before it reaches the context window. On token-heavy sources (a long docs page, a GitHub README) this is the difference between paying for the whole page and paying for the part that answered the question; there is no extra charge for the code execution it uses. It needs a **Claude 4.6 or later** model — on anything older (Haiku 4.5, Sonnet 4.5) the API rejects the request unless the tool is called directly, so set `"dynamic_filtering": false` on those profiles. Disabling it also restores Zero Data Retention eligibility, which the sandbox otherwise forfeits.
-
 Web search is **not free** — Anthropic bills per search (plus the tokens the results add) — so scope the allowlist and `max_uses` deliberately, and lean on a prompt that tells the bot to search only when a question actually turns on current or authoritative information. Search activity logs as `[web] ...` lines, and long multi-search turns are handled transparently (the engine follows Anthropic's `pause_turn` continuations up to a small cap, so a slow search doesn't truncate the reply).
