Sync model card with GitHub README

Sync the model card with the GitHub README (https://github.com/OpenMOSS/MOSS-Transcribe-Diarize/blob/main/README.md), adapted for the Hugging Face context:

- Serving order now matches GitHub: SGLang Omni (recommended) is presented before vLLM, each in its own section, including the transcription API parameter table and single-H100 benchmark results.
- Logos are referenced via absolute raw.githubusercontent.com URLs; the architecture image uses the Model_Architecture.png hosted in this repo.
- Relative GitHub links (e.g. examples/prompts.md) converted to absolute URLs.
- Kept the HF YAML metadata, the trust_remote_code note, and the MLC-SLM challenge link from the current card.
- Dropped the HF self-badge and the Trendshift badge; added the GitHub badge.

-MOSS-Transcribe-Diarize 0.9B is an end-to-end audio understanding model for long-form multi-speaker transcription, diarization, timestamps, and acoustic event awareness.
-
-It supports transcription and diarization across 50+ languages, single-pass inference on audio recordings up to 90 minutes long, and custom hotword prompting for domain-specific terms.
-
-Given an audio or video file, the model generates a compact speaker-aware transcript in one pass, including timestamps and anonymous speaker labels such as `[S01]`, `[S02]`, and beyond.
+MOSS-Transcribe-Diarize 0.9B is an open-source SOTA end-to-end audio understanding model for long-form multi-speaker transcription, diarization, timestamps, and acoustic event awareness. MOSS-Transcribe-Diarize Pro is a stronger model with higher overall performance and will be available through API access soon.

 ## Introduction
 
-MOSS-Transcribe-Diarize 0.9B turns real-world long-form audio into structured, speaker-aware transcripts in one pass. Instead of stitching together separate ASR and diarization systems, it jointly performs speech transcription and speaker diarization, producing time-aligned text with consistent speaker labels.
+MOSS-Transcribe-Diarize is our flagship SOTA model family for turning real-world long-form audio into structured, speaker-aware transcripts in one pass. Instead of stitching together separate ASR and diarization systems, these models jointly perform speech transcription and speaker diarization, producing time-aligned text with precise timestamps and consistent speaker labels such as `[S01]`, `[S02]`, and beyond.
+
+Built for meetings, calls, podcasts, interviews, lectures, and video content, MOSS-Transcribe-Diarize is designed to handle long, messy, multi-speaker recordings where reliability matters. It can also emit optional acoustic event annotations, giving downstream systems a richer understanding of what happened, who spoke, and when.
+
+MOSS-Transcribe-Diarize supports 50+ languages.
 
-The model is built for meetings, calls, podcasts, interviews, lectures, videos, and other long or messy multi-speaker recordings. It can also emit acoustic event annotations, giving downstream systems a richer view of what happened, who spoke, and when.
+The model accepts raw audio and emits a compact timestamped transcript. The canonical output format is:
 
-Core capabilities:
+```text
+[start_time][Sxx]transcribed speech[end_time]
+```
+
+Timestamps are expressed in seconds, and adjacent segments are concatenated into a single stream, for example:
 
-* **Long-form transcription**: Converts long audio or video recordings into timestamped text.
-* **Speaker-aware diarization**: Assigns anonymous speaker labels such as `[S01]` and `[S02]` without a separate diarization pipeline.
-* **Promptable generation**: Supports custom transcription instructions, hotwords, and acoustic event annotations.

 ## Evaluation
 
-We evaluate MOSS-Transcribe-Diarize using three objective metrics: Character Error Rate (CER), concatenated minimum-permutation Character Error Rate (cpCER), and Delta-cp. Lower is better for all metrics. A dash (`-`) indicates that the result is unavailable.
