## ZYR 1 (zyr-1)

**Tagline**: Flash-fast everyday answers
**Speed**: Fast
**Parameters**: ~7B (Gemini 4.7 Flash)
**Powered by**: Google Gemini 4.7 Flash via Z.ai SDK
**Context window**: 32k tokens
**Pricing**: Free

### Best for
- Quick factual questions
- Simple math
- Casual conversation
- Greeting and small talk
- Definitions and lookups

### Pipeline
1. Single direct call to Gemini 4.7 Flash

### Capabilities
- Sub-1-second responses
- No thinking overhead
- Low token usage
- Streaming responses

### Limitations
- Not suitable for complex reasoning
- Limited coding capability
- No multi-step planning
- No deep thinking

## ZYR 2 (zyr-2)

**Tagline**: Balanced reasoning with GLM 5
**Speed**: Balanced
**Parameters**: ~100B+ (GLM 5)
**Powered by**: Z.ai GLM 5
**Context window**: 32k tokens
**Pricing**: Free

### Best for
- Work and study questions
- Longer conversations
- Structured answers
- General coding help
- Writing assistance

### Pipeline
1. Planner — breaks the query into sub-tasks
2. Executor — generates the full response
3. Quality Evaluator — checks for gaps and polishes

### Capabilities
- 3-stage reasoning pipeline
- Better structured than ZYR 1
- Good for medium-complexity tasks
- Supports all chat modes (@agent, @plan, @code, etc.)

### Limitations
- Slower than ZYR 1 (~2-4s)
- Not as deep as ZYR 3 for code
- Not as powerful as ZYR 4 for hard problems

### How it works
ZYR 2 runs a 3-stage pipeline on GLM 5: Plan → Execute → Evaluate. The Planner decomposes the query, the Executor generates a complete answer, and the Quality Evaluator checks for gaps before returning.

## ZYR 3 (zyr-3)

**Tagline**: Coding beast — 10-stage pipeline tuned for code
**Speed**: Max
**Parameters**: Multi-model ensemble (GLM 5.1 + GPT 4.4o + GPT 4o)
**Powered by**: GLM 5.1 Max Deep Thinking + GPT 4.4o Mini + GPT 4o via Z.ai SDK
**Context window**: 32k tokens
**Pricing**: Free

### Best for
- Production code generation
- Debugging complex issues
- Code refactoring
- Architecture design
- Algorithm implementation
- Code review

### Pipeline
1. Router — classifies query complexity
2. Researcher — identifies relevant technologies
3. Planner — breaks down the implementation
4. Executor — generates the code
5. Synthesizer — merges outputs cleanly
6. Critic — reviews for bugs and security
7. Optimizer — improves readability and performance
8. Validator — fact-checks APIs and syntax
9. Quality Evaluator — final polish
10. Reviewer — last-pass review

### Capabilities
- 10-stage pipeline tuned specifically for code
- Multi-model ensemble (GLM + GPT 4.4o + GPT 4o)
- Deep thinking enabled on critical stages
- Auto-collapses to 3-stage fast path for simple queries

### Limitations
- Slower than ZYR 1/2 (~5-15s for complex code)
- Can over-engineer simple tasks
- Pipeline visible to user (can be noisy)

### How it works
ZYR 3 runs a 10-stage pipeline specifically tuned for code. Multi-model ensemble: GLM 5.1 Max Deep Thinking for reasoning, GPT 4.4o Mini for speed, GPT 4o for quality. Each stage has a specialized persona. The Router collapses to a 3-stage fast path for simple queries.

## ZYR 4 BEAST (zyr-4)

**Tagline**: ZYR AI CORE v2 · 1T+ params · 10 models · SOTA-tuned
**Speed**: Beast
**Parameters**: 1T+ (10-model ensemble)
**Powered by**: 10 models in parallel — Nemotron Ultra 550B, Nemotron Super 120B, Nemotron Nano 30B, GPT-OSS 20B, Gemma 4 26B, Tencent Hy3, GLM, OpenZen Large, OpenZen Fast, OpenZen Reasoning
**Context window**: 200k+ effective (via compression)
**Pricing**: Free

### Best for
- Hardest reasoning problems
- Multi-step math (self-consistency voting)
- Long-context analysis (200k+ effective)
- Vision/image understanding
- Writing that needs to beat GPT-4/Claude quality
- Knowledge questions requiring web search
- Any task where you want the best possible answer

### Pipeline
1. Smart Router — 4-tier dispatch (instant/fast/standard/deep) via regex
2. Context Compression — summarize old turns when history > 20k chars
3. Web Search — auto-triggered for current-events/knowledge queries
4. ZCG Execute — parallel draft generation across 10 models
5. GLM Synthesis — deep-thinking merge of all drafts
6. TCG Validation — code testing (only for code tasks)
7. Polish Pass — writer-editor persona for prose quality
8. Self-Consistency — 3-sample majority vote for math/reasoning

### Capabilities
- 10-model ensemble with 1T+ total parameters
- 4-tier smart routing (instant: 458ms, fast: 248ms, standard: 6-17s, deep: 4s)
- Self-consistency voting for math (3 GLM samples, majority vote)
- Context compression for 200k+ effective window
- Vision pass-through via GLM vision API
- Web search integration via Z.ai SDK
- Writer-quality polish pass (beats GPT-4 on prose)
- TCG code validation only when needed (faster)
- Backend-only ZYR AI CORE SYSTEM (ZCG + ACN + SL + CG + TCG)

### Limitations
- Slower than ZYR 1 for trivial queries (but router avoids this)
- Can hit rate limits on OpenRouter free tier under heavy load
- Vision limited to GLM's image capabilities (no video)
- 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. When conversation history exceeds 20k chars, old turns are summarized (effective context: 200k+ tokens).

The 10 underlying models: 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)

**Tagline**: Natural TTS · powered by Z.ai
**Speed**: Balanced
**Parameters**: GLM 5 + Z.ai TTS (tongtong voice)
**Powered by**: Z.ai GLM 5 + Z.ai TTS (24 kHz WAV)
**Context window**: 32k tokens
**Pricing**: Free

### 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

### 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. Long text is split into 1024-char chunks and synthesized sequentially.
