GLM-5.2 is the current GLM default on VM0 for Z.AI API-key users and is also available through VM0 Managed via OpenRouter. It keeps the GLM series' long-context profile while becoming the preferred Z.AI route for new agents.
Use it for large codebases, large document sets, and cost-sensitive long-context planning where Sonnet-class pricing is unnecessary. GLM-5.1 remains available for compatibility, but new Z.AI routes should start on GLM-5.2 unless a workflow has been tuned specifically against 5.1.
¿Qué es GLM-5.2?
June 2026 · Current default model in VM0's Z.AI / GLM route.
GLM-5.2 extends the GLM 5 family as the current Z.AI default exposed by VM0. It is available through VM0 Managed, where VM0 routes to OpenRouter with the upstream id z-ai/glm-5.2, and through direct Z.AI API keys using the canonical glm-5.2 id.
The route is Anthropic-compatible, so Claude-style agents can keep the same runtime interface. Existing GLM-5.1 agents do not need to migrate immediately, but new Z.AI-backed agents should prefer GLM-5.2.
On VM0 Managed it sits at x0.4 credits, matching GLM-5.1's cost tier while taking over the Z.AI default slot.
Qué destaca de GLM-5.2
Características principales de arquitectura y capacidades.
GLM-5.2 is exposed on VM0 through Anthropic-compatible endpoints. VM0 Managed uses OpenRouter's z-ai/glm-5.2 id; direct Z.AI BYOK uses glm-5.2.

Cómo se comporta GLM-5.2 en la práctica
Comportamiento observado en ejecuciones de agentes en producción.
Long-context work
GLM-5.2 is best used when the agent needs a large working set: repositories, documentation folders, design notes, or long research material.
Cost control
At x0.4 credits it is a cost-saving alternative to Sonnet-class routes for workflows where context size and price matter more than maximum English reasoning depth.
Routing
VM0 Managed routes through OpenRouter using z-ai/glm-5.2; direct Z.AI API keys use glm-5.2. Both paths keep the Claude-compatible agent interface.
Mejores tareas para GLM-5.2
Whole-repo review on a budget
Use GLM-5.2 when the agent needs to inspect a large codebase and produce concrete file-level recommendations without paying for a premium reasoning model on every pass.
Large document synthesis
Load policy documents, tickets, transcripts, or internal docs together and ask for cross-document patterns. The long context and x0.4 multiplier keep repeated runs practical.
Z.AI BYOK default route
Teams using a direct Z.AI API key get GLM-5.2 as the default VM0 model while retaining GLM-5.1 for existing tuned workflows.
Cuándo evitar GLM-5.2
Skip GLM-5.2 for workflows that depend on vision input, or when maximum English-language reasoning and tool routing quality matter more than context size and cost.
GLM-5.2 vs otros modelos
GLM-5.2 vs GLM-5.1
GLM-5.1 remains available for compatibility. GLM-5.2 is the default choice for new Z.AI routes on VM0.
GLM-5.2 vs Kimi K2.7 Code
Both sit in cost-saving territory. Kimi is the Moonshot default and a strong code-focused alternative; GLM-5.2 is the preferred Z.AI long-context route.
GLM-5.2 vs Claude Sonnet 4.6
Sonnet 4.6 remains the stronger default for premium tool-routing quality. GLM-5.2 is cheaper and better suited when context size dominates.
Conclusión: ¿deberías usar GLM-5.2?
Pick GLM-5.2 as the default Z.AI route on VM0. Keep GLM-5.1 only for compatibility with workflows already tuned against it.
Preguntas frecuentes
Is GLM-5.2 available through VM0 Managed?
Yes. VM0 Managed routes GLM-5.2 through OpenRouter with the upstream id z-ai/glm-5.2.
Is GLM-5.2 the default for direct Z.AI API keys?
Yes. The Z.AI provider defaults to glm-5.2 while keeping glm-5.1 available.
Does GLM-5.2 support image input?
No. VM0 exposes GLM-5.2 for text and code agents. Use Claude Sonnet 4.6 or Kimi K2.7 Code when vision input is required.
Alternativas
Usar GLM-5.2 en VM0
Dos formas de acceder a GLM-5.2 en VM0
VM0 admite GLM-5.2 como modelo Built-in facturado en créditos VM0, y mediante bring-your-own con una Z.AI API key. La ruta Built-in usa enrutamiento gestionado de VM0 y el multiplicador de créditos explicado abajo; la ruta bring-your-own te factura directamente con el proveedor upstream y omite la conversión de créditos VM0.
Recomendación de VM0
VM0 posiciona GLM-5.2 como una opción de ahorro en lugar de un modelo principal de agente. Úsalo para optimizar el coste unitario en trabajo no principal, como clasificación masiva, prefiltros, respuestas cortas con requisitos de latencia o agentes heredados fijos, manteniendo Claude Opus 4.7, Claude Opus 4.6 o Claude Sonnet 4.6 en los pasos que deciden la ejecución.
Créditos y el multiplicador ×0.4
Cada modelo Built-in en VM0 se valora como un múltiplo de Claude Sonnet 4.6, que establece la base de ×1 crédito. GLM-5.2 factura a ×0.4 créditos. El multiplicador es lo que aparece en tu factura de VM0; el precio de lista del proveedor en la tabla de arriba es lo que cobra el proveedor upstream antes de que VM0 lo convierta en créditos.
GLM-5.2 factura a ×0.4, lo que significa que un paso aquí cuesta solo 0.4× los créditos de un paso equivalente en Sonnet 4.6 (la base ×1). Esto lo sitúa muy por debajo de la base de créditos y lo convierte en la elección natural para trabajo en segundo plano de alto volumen donde el coste por paso importa más que la máxima calidad de razonamiento.
Disponible en VM0 desde June 2026.
