## Performance-Claim (laut Z.ai)
|
|||
|
|
|
|||
|
|
- GLM-5.3-Flash outperformt GLM-5.2 auf jedem Effort-Level
|
|||
|
|
- Auf chat.z.ai Code Bench „performs on par with Claude Opus 4.8"
|
|||
|
|
|
|||
|
|
## Architektur-Details (aus HuggingFace Model Card)
|
|||
|
|
|
|||
|
|
- **Hybrid-Attention:** Erstmals in der GLM-Serie kombiniert Sparse Attention + Linear Attention → senkt Long-Context-Serving-Kosten bei erhaltener Präzision
|
|||
|
|
- **Manifold-Constrained Hyper-Connections (mHC):** verbessert Scaling-Effizienz
|
|||
|
|
- **30T-Token multimodaler Pre-Training-Corpus**
|
|||
|
|
- **Neu trainiertes Base Model** (kein Incremental-Update von 5.2)
|
|||
|
|
|
|||
|
|
## Lokale Deployment-Frameworks
|
|||
|
|
|
|||
|
|
- SGLang, vLLM, TokenSpeed, KTransformers (alle mit eigenen Cookbook-/Recipe-Links auf der HF-Page)
|
|||
|
|
|
|||
|
|
## Benchmark-Footnotes (aus HF Model Card, Evaluation-Details)
|
|||
|
|
|
|||
|
|
- **HLE w/ tools (full set):** temp=1.0, top_p=0.95, max 163.840 Output-Tokens, 300K Kontext mit Context-Management, Judge: GPT-5.6-luna (medium)
|
|||
|
|
- **NL2Repo:** temp=1.0, max 64K Output, 1M Kontext, Rule-based + LLM-basierte Anti-Cheating-Checks
|
|||
|
|

|
|||
|

|
|||
|
|

## Ox-Alpha-Enthüllung
|
|||
|
|
|
|||
|
|
Der X-Post bestätigt explizit: **„Previously previewed as Ox Alpha"**. Damit ist das Rätsel um das anonyme OpenRouter-Modell (siehe `raw/xpost/2026-08-23_insiderleak-ox-alpha-anonymous-model.md`) offiziell aufgelöst:
|
|||
|
|
|
|||
|
|
- **Owner:** Z.ai (Zhipu AI) — wie von der Community bereits zu ~80–90 % vermutet (GLM-Tokenizer, API-Fehlercodes, chinesische Backend-Logs)
|
|||
|
|
- **Stealth-Playbook:** Anonym auf OpenRouter legen → Daten/Echt-Last sammeln → benannt releasen
|
|||
|
|
- **4.096 Max-Output-Cap aus dem EP106-Listing** war das tatsächliche Output-Limit des Stealth-Previews; der 131k-Wert aus dem Community-Gegencheck war vermutlich ein anderer Messpunkt oder fehlerhaft
