-To test a running LocalAI server from the terminal, open an interactive chat session from another shell. Inside the prompt, `/models` lists installed models and `/model <name>` switches between them.
-
-```bash
-# Terminal 1
-local-ai run llama-3.2-1b-instruct:q4_k_m

-# Terminal 2
-local-ai chat --model llama-3.2-1b-instruct:q4_k_m

 > **Automatic Backend Detection**: LocalAI automatically detects your GPU capabilities and downloads the appropriate backend. For advanced options, see [GPU Acceleration](https://localai.io/features/gpu-acceleration/).

-### Streaming the pipeline
-
-By default each stage runs to completion before the next begins: the whole utterance is transcribed, the full LLM reply is generated, then it is synthesized. Each stage can instead be streamed incrementally, which lowers the time-to-first-audio of a turn:
-
-```yaml
-name: gpt-realtime
-pipeline:
-  vad: silero-vad-ggml
-  transcription: whisper-large-turbo
-  llm: qwen3-4b
-  tts: tts-1
-  streaming:
-    llm: true             # stream LLM tokens as transcript deltas
-    tts: true             # emit audio deltas per synthesized chunk
-    transcription: true   # stream transcript text deltas of the user's speech
-    clause_chunking: true # synthesize each clause as soon as it completes
-```
-
-- **streaming.tts**: emit a `response.output_audio.delta` per audio chunk the TTS backend produces (requires a backend that supports streaming synthesis), instead of one delta for the whole utterance. Falls back to a single unary delta otherwise.
-- **streaming.transcription**: stream `conversation.item.input_audio_transcription.delta` events as the transcript is produced (requires a transcription backend that supports streaming).
-- **streaming.llm**: stream the LLM reply token-by-token as `response.output_audio_transcript.delta` events. The full reply is buffered and synthesized once it is complete — streamed as audio chunks when `streaming.tts` is enabled (and the TTS backend supports it), otherwise as a single unary delta. Reasoning/thinking is always stripped from the spoken transcript. Tool calls are supported while streaming when the LLM uses its tokenizer template (`use_tokenizer_template: true`): the backend's autoparser then delivers content and tool calls separately, so the spoken transcript never leaks tool-call tokens. Grammar-based function calling keeps the buffered path.
-- **streaming.clause_chunking**: instead of buffering the whole reply before TTS, split it into speakable clauses and synthesize each as soon as it completes, lowering the time-to-first-audio. The splitter is script-aware: it uses Unicode sentence segmentation (so it handles CJK `。！？` with no whitespace), CJK clause punctuation (`，、；：`), and Thai/Lao spaces — it does **not** rely on whitespace sentence boundaries, so it works for languages such as Chinese, Japanese and Thai where the old per-sentence approach degraded to whole-message buffering. Requires `streaming.llm`; scripts that genuinely need a dictionary (e.g. Khmer, Burmese) simply stay buffered until a space or end-of-message. Off by default.
-
-All streaming flags are off by default, so existing pipelines are unaffected.
-
-### Disabling thinking
-
-For reasoning models, you can force the pipeline LLM's thinking off without editing the LLM model config:
-
-```yaml
-pipeline:
-  llm: qwen3-4b
-  disable_thinking: true   # maps to enable_thinking=false for the realtime LLM
-```
-
-This is applied only to the realtime session's copy of the LLM config, so it does not affect other users of the same model. Leave it unset to use the LLM model config's own reasoning settings.

-// leaving content empty (breaking short/direct answers such as session names or
-// JSON summaries). Genuine reasoning tags already present in the content still
-// extract, because dropping the synthetic prefill does not affect them.
