GLM-5 9B vs Grok Build 0.1
GLM-5 9B (2026) and Grok Build 0.1 (2026) compare a standalone API model against a coding-specialized model. GLM-5 9B ships a 262k-token context window, while Grok Build 0.1 ships a 256k-token context window. This page treats the result as workflow and deployment fit, not a universal model winner.
Treat this as a product-type comparison: GLM-5 9B is standalone API model, while Grok Build 0.1 is coding-specialized model. Choose based on workflow fit before reading any benchmark or price row as decisive.

Deep dive
The capability footprint differs most on vision: Grok Build 0.1, multimodal input: Grok Build 0.1, and structured outputs: Grok Build 0.1. Both models share reasoning mode, function calling, and tool use, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.
Pricing coverage is uneven: GLM-5 9B has no token price sourced yet and Grok Build 0.1 has $1/1M input tokens. Provider availability is 0 tracked routes versus 3. Treat unknown pricing as an integration gap, then verify the route you will actually call before estimating production spend.
Choose GLM-5 9B when long-context analysis and larger context windows are central to the workload. Choose Grok Build 0.1 when coding workflow support and broader provider choice are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship. This keeps the decision grounded in measurable tradeoffs instead of brand-level assumptions. It also helps separate model capability from provider packaging, which can change cost and latency.
FAQ
Which has a larger context window, GLM-5 9B or Grok Build 0.1?
GLM-5 9B supports 262k tokens, while Grok Build 0.1 supports 256k tokens. That gap matters most for long documents, large codebases, retrieval-heavy agents, and conversations where earlier context must remain visible.
Is GLM-5 9B or Grok Build 0.1 open source?
GLM-5 9B is listed under MIT. Grok Build 0.1 is listed under Proprietary. License labels affect whether you can self-host, redistribute weights, or rely only on hosted APIs, so confirm the upstream license before deployment.
Which is better for vision, GLM-5 9B or Grok Build 0.1?
Grok Build 0.1 has the clearer documented vision signal in this comparison. If vision is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.
Which is better for multimodal input, GLM-5 9B or Grok Build 0.1?
Grok Build 0.1 has the clearer documented multimodal input signal in this comparison. If multimodal input is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.
Which is better for reasoning mode, GLM-5 9B or Grok Build 0.1?
Both GLM-5 9B and Grok Build 0.1 expose reasoning mode. The better choice depends on benchmark fit, context budget, pricing, and whether your provider route exposes the same capability surface.
Where can I run GLM-5 9B and Grok Build 0.1?
GLM-5 9B is available on the tracked providers still being sourced. Grok Build 0.1 is available on xAI Console, Vercel AI Gateway, and OpenRouter. Provider coverage can affect latency, region availability, compliance posture, and fallback options.
