GLM-5.2 on VM0. Z.AI's default long-context model
The current Z.AI default on VM0. Up to a 1M-token context window, Anthropic-compatible routing, and cost-saving x0.4 VM0 Managed pricing.

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.
GLM-5.2とは？
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.
GLM-5.2の注目ポイント
アーキテクチャと機能の主な特徴。
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.
スペック概要
GLM-5.2のベンチマーク
Treat GLM-5.2 as the preferred GLM route on VM0. Third-party rankings can move quickly, so VM0 keeps the page focused on routing, cost, and operational fit rather than frozen leaderboard percentages.

GLM-5.2の実践的な挙動
本番エージェント実行で観測された動作。
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.
GLM-5.2に最適なエージェントタスク
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.
GLM-5.2を避けるべきケース
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 他のモデル
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.
結論: GLM-5.2を使うべきか？
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.
よくある質問
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.

VM0でGLM-5.2を使う
VM0でGLM-5.2にアクセスする2つの方法
VM0はGLM-5.2を、VM0クレジットで課金されるBuilt-inモデル、およびZ.AI API keyを使用したBring-your-ownの2通りでサポートしています。Built-inパスではVM0 Managedルーティングと後述のクレジット倍率が適用され、Bring-your-ownパスでは上流プロバイダーに直接課金され、VM0クレジットへの変換は行われません。
VM0の推奨
VM0はGLM-5.2をコアエージェントモデルではなく、コスト削減オプションとして位置付けています。一括分類、プレフィルター、レイテンシが重要な短い返信、固定のレガシーエージェントなど、非コア作業の単価最適化に使用し、実行を左右するステップにはClaude Opus 4.7、Claude Opus 4.6、またはClaude Sonnet 4.6を維持します。
クレジットと×0.4倍率
VM0のすべてのBuilt-inモデルは、×1クレジット基準となるClaude Sonnet 4.6の倍数で価格設定されています。GLM-5.2は×0.4クレジットで課金されます。倍率はVM0の請求書に表示されるもので、上記の価格表のベンダー定価はVM0がクレジットに変換する前に上流プロバイダーが請求する金額です。
GLM-5.2は×0.4で課金されます。つまり、1ステップのコストはSonnet 4.6（×1基準）の同等ステップのわずか0.4倍です。これはクレジット基準を大きく下回り、ピーク時の推論品質よりもステップあたりのコストが重視される高ボリュームのバックグラウンドワークに自然な選択肢です。
