Deep dive

The capability footprint is close: both models cover reasoning mode, function calling, tool use, and structured outputs. That makes context budget, benchmark fit, and provider maturity more important than a simple checklist. If your application depends on one integration detail, verify it against the provider route you plan to use, not just the base model listing.

For cost, GLM-5 Turbo lists $1.20/1M input and $4/1M output tokens on the cheapest tracked provider, while Grok Build 0.1 lists tiered pricing: 0-200,001t is $1/1M input and $2/1M output; 200,001t+ is $2/1M input and $4/1M output. A 70/30 input-output blend puts Grok Build 0.1 lower by about $0.74 per million blended tokens. For tiered rows, this cheapest-track view can understate interactive or fast-lane spend, so compare the tier you will actually use. Availability is 2 providers versus 3, so concentration risk also matters.

Choose GLM-5 Turbo when provider fit are central to the workload. Choose Grok Build 0.1 when coding workflow support, larger context windows, and lower cheapest-tier input-token cost are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.

FAQ

Which has a larger context window, GLM-5 Turbo or Grok Build 0.1?

Grok Build 0.1 supports 256k tokens, while GLM-5 Turbo supports 200k tokens. That gap matters most for long documents, large codebases, retrieval-heavy agents, and conversations where earlier context must remain visible.

Which is cheaper, GLM-5 Turbo or Grok Build 0.1?

GLM-5 Turbo lists $1.20/1M input and $4/1M output tokens on the cheapest tracked provider. Grok Build 0.1 lists tiered pricing: 0-200,001t is $1/1M input and $2/1M output; 200,001t+ is $2/1M input and $4/1M output. Compare the tier you will actually use; cheap async pricing can overstate savings for interactive workflows. Provider discounts or batch pricing can still change the final bill.

Is GLM-5 Turbo or Grok Build 0.1 open source?

GLM-5 Turbo is listed under Proprietary. 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 reasoning mode, GLM-5 Turbo or Grok Build 0.1?

Both GLM-5 Turbo 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.

Which is better for function calling, GLM-5 Turbo or Grok Build 0.1?

Both GLM-5 Turbo and Grok Build 0.1 expose function calling. 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 Turbo and Grok Build 0.1?

GLM-5 Turbo is available on OpenRouter and Vercel AI Gateway. 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.
