- Web search adds 1-3s latency when triggered
How it works
ZYR 4 BEAST v2 runs the ZYR AI CORE SYSTEM — a backend-only AI operating system. A regex-based Smart Router classifies the query into 4 tiers: instant (greetings, 1 model, <1s), fast (short Q&A, 1 model, <1s), standard (code/creative/knowledge, 10-model ensemble + polish, 6-17s), deep (math/reasoning, 3 GLM samples with self-consistency voting, ~4s). When the user asks about current events or facts, a web search runs via Z.ai SDK and results are injected into LLM context for grounded answers with citations. When conversation history exceeds 20k chars, old turns are summarized into a compact context note (effective context window: 200k+ tokens). For code tasks, the TCG (Testing Code Agent) validates generated code before returning. For all tasks, a final GLM deep-thinking polish pass with a writer-editor persona ensures GPT-4/Claude-quality prose. The 10-model ensemble has 1T+ total parameters: Nemotron Ultra 550B + Nemotron Super 120B + Nemotron Nano 30B + GPT-OSS 20B + Gemma 4 26B + Tencent Hy3 + GLM + 3 OpenZen models.
ZYR Voice (zyr-voice)
Natural TTS · powered by Z.ai
Specifications
- Parameters: GLM 5 + Z.ai TTS (tongtong voice)
- Speed tier: Balanced
- Context window: 32k tokens
- Pricing: Free
- Powered by: Z.ai GLM 5 + Z.ai TTS (24 kHz WAV)
- Info URL: https://zyrai.space-z.ai/zyr/zyr-voice
Best for
- Audio playback of responses
- Accessibility (visually impaired users)
- Hands-free consumption
- Podcast-style content
- Voice-first interfaces
Pipeline
- 1. ZYR 2's 3-stage pipeline (Plan → Execute → Evaluate)
- 2. Markdown stripped for natural speech
- 3. Z.ai TTS synthesis (tongtong voice, 24 kHz WAV)
Capabilities
- Natural-sounding Z.ai TTS voice (tongtong)
- 24 kHz WAV output at 16-bit mono PCM
- Markdown stripping (no 'backtick backtick python' in audio)
- Stop button during playback
- Voice button on every AI message
- Long-text chunking with rate-limit retry
Limitations
- TTS adds 1-3s latency on first play
- Voice quality limited to Z.ai's available voices
- Code blocks read as '(code block)' instead of full content
- Rate limits on Z.ai TTS API (sequential chunking with backoff)
How it works
ZYR Voice uses ZYR 2's balanced pipeline to generate the text response, then passes it through the Z.ai TTS API (voice: tongtong, format: WAV, 24 kHz). Markdown formatting is stripped before synthesis (code fences become '(code block)', bold/italic markers removed, links reduced to text). Long text is split into 1024-char chunks and synthesized sequentially with exponential backoff on rate limits. WAV chunks are concatenated with patched headers into a single audio file. The voice button appears on every AI message across all ZYR models, not just ZYR Voice.
