OpenAI's gpt-4o-transcribe and gpt-4o-mini-transcribe model family only accepts "json" or "text" as response_format — sending "verbose_json" returns a 400 unsupported_value error and the setup test fails. Make transcriptionResponseFormat model-aware: models whose name contains "transcribe" get "json"; all others (Groq whisper-large-v3, etc.) keep "verbose_json" so the hallucination filter's no_speech_prob segments remain available. The hallucination filter already degrades gracefully when segments are absent, so there is no second change needed. Also add an explicit 400 case to friendlyHTTPMessage so users see "Check your model name and Base URL in Settings" rather than the generic fallback, which is actionable for this exact failure mode.

… rate-limited, instead of retrying it every dictation When the post-processing (cleanup) model returns HTTP 429, record a short per-model cooldown and route the next requests to the backup model up-front, instead of retrying the rate-limited model on every dictation. Daily limits are persisted and surfaced in Settings so the user can see when a model is unavailable until reset. Most logic lives in a new self-contained LLMCooldownManager so the PostProcessingService backbone keeps only minimal hooks. The duration parser rejects negative / non-finite header values so a malformed 429 can never produce a bad cooldown. Modified files: - Sources/LLMCooldownManager.swift - Sources/PostProcessingService.swift - Sources/SettingsView.swift
…e-exit, reset-date label) - Persist a daily cooldown by header kind: when the value comes from the daily (Requests-Per-Day) reset header, persist it even if it resets in under an hour, so it survives restart and shows in Settings (was kept in memory only). - After an up-front cooldown swap, still return the safe raw transcript on a suspected-instruction-execution instead of throwing the error. - Settings reset label now includes the date when the cooldown expires on a later day, so a cross-midnight daily reset is not shown as an ambiguous bare time. Modified files: - Sources/LLMCooldownManager.swift - Sources/PostProcessingService.swift - Sources/SettingsView.swift
…t when both models cool) - rateLimitCooldown now checks x-ratelimit-remaining-requests <= 0 first and uses the daily (RPD) reset, so a short near-reset daily window is still persisted and shown in Settings even when retry-after is also present. - effectivePrimary returns nil when BOTH the primary and the fallback are cooling; the wrappers then skip the doomed request and degrade gracefully (raw transcript for cleanup, selection unchanged for Edit Mode). Modified files: - Sources/LLMCooldownManager.swift - Sources/PostProcessingService.swift
Add a new Cleanup settings card with a toggle that, when on, skips the LLM post-processing step so the raw transcript is pasted verbatim, including profanity and informal wording. Voice macros and Edit Mode continue to run as before.
Address the interaction between the Preserve exact wording toggle and the Output Language setting. Previously the toggle skipped postProcess() entirely, which also silently dropped translation. Users who had configured an Output Language stopped seeing translated output once they enabled verbatim mode. Add PostProcessingService.translateVerbatim, a translate-only path that shares the primary/fallback model selection but uses a stripped- down system prompt: literal translation, keep filler words, keep informal wording, keep profanity, no reformatting. processTranscript now routes: - preserveExactWording=off: unchanged (regular postProcess). - preserveExactWording=on, no Output Language: skip LLM entirely. - preserveExactWording=on, Output Language set: translateVerbatim. Thread preserveExactWording as an explicit function parameter instead of reading from self, matching how outputLanguage and the vocabulary settings are already passed. Add TranscriptProcessingOutcome cases for the two new paths and surface them in the status message. Persist the raw dictation for retry when translateVerbatim fails, matching postProcessingFailedFallback.
sanitizePostProcessedTranscript treats the string "EMPTY" as a sentinel meaning "nothing to paste" because the cleanup system prompt explicitly instructs the model to return that value when appropriate. The verbatim translation prompt has no such instruction, so applying the same sanitizer risks silently dropping a legitimate literal translation of the word "empty" into the target language. Add sanitizeVerbatimTranslation, which only trims whitespace and strips wrapping quotes.
The previous 20s request timeout and 30s resource budget are too tight for local ASR and post-processing models, which routinely take longer under load. - Shared session (API validation + post-processing): timeoutIntervalForRequest 20s→120s, timeoutIntervalForResource 30s→300s - Upload session (transcription): timeoutIntervalForRequest 300s, timeoutIntervalForResource removed (no budget cap) — a chunking proxy that processes long audio in segments needs effectively unlimited time Without this, recordings longer than ~20 s triggered "Transcription timed out" or silently dropped because the URLSession killed the request before the local model finished responding.

The Custom Vocabulary, System Prompt, and Context Prompt editors wrote their value into the shared AppState on every keystroke. Because AppState is a single ObservableObject observed by the whole settings window and the menu bar, each keystroke fired objectWillChange and rebuilt all of those views. On a macOS 13 target there is no per-property observation to scope the invalidation, so typing in these fields was noticeably laggy (measured around 85ms of main-thread work per keystroke, with the menu bar rebuilding on every character). These fields now commit to AppState when the editor loses focus, matching what the API base URL and key fields already do, and also on disappear so nothing typed is lost if the window closes while focused. The prompt test runners commit first so they still test the latest text. Fixes #274 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Verbatim-translation path bypasses the cooldown/circuit-breaker mechanism entirely.
processWithFallback and processCommandTransformWithFallback both gate the primary call through LLMCooldownManager.shared.effectivePrimary(...) and register a cooldown via setCooldown when they hit a 429 (lines 315-325, 398-407, 565-573, 705-711). translateVerbatimWithFallback/translateVerbatim do neither:
translateVerbatimWithFallbackcallstranslateVerbatimdirectly withresolvedPrimaryModel(), with no cooldown check first — it will keep hammering a model other request paths have already identified as rate-limited.- The private
translateVerbatim(transcript:targetLanguage:model:)throws a bare.requestFailed(429, ...)on rate-limit instead of.rateLimited, and never callsLLMCooldownManager.shared.setCooldown(...). So a 429 hit via this path is invisible to the circuit breaker used byprocess()/processCommandTransform(), and invisible to the new Settings daily-limit warning label (which reads from the sameLLMCooldownManagerUserDefaults keys).
This inconsistency means the "Preserve exact wording" + Output Language combination can silently keep re-hitting an exhausted model and never surface a cooldown to the rest of the app.
