Model comparison

GLM-5 vs GLM-5-Turbo

Updated July 29, 2026. Public scores include evidence status and uncertainty. They are not guarantees for a specific workload. This is a same-family comparison, so migration details appear when the source data supports them.

GLM-5

Z.AI

65.2/100

Supported · Public rank #31

65.9/100

Supported · Public rank #29

90% interval 56.1–75.7

GLM-5-Turbo has the higher public score estimate, 65.92 versus 65.24, but the 90% score intervals overlap. Treat that as a lead, not a settled winner.

1 results are shared. Category rows based on different benchmark sets are marked directional and do not name a winner.

Which one for your work

Recommendations appear only when a shared evidence basis or an explicit operating constraint supports the call. Secondary and unsupported use cases stay disclosed below the initial list.

  • Chat turn cost

    1K fresh input + 500 output tokens

    GLM-5

    GLM-5 has the lower estimated token cost for this stated workload. Costs use the listed standard API rates.

    Not enough matched evidence

    The page does not recommend a cost winner because at least one model cannot fit the stated workload in one request. GLM-5 does not fit this workload in one request. GLM-5-Turbo does not fit this workload in one request. GLM-5 has no published cached-input rate, so cached tokens use its listed input rate. GLM-5-Turbo has no published cached-input rate, so cached tokens use its listed input rate.

Shape of the matched evidence

Only shared public evidence is shown. Sparse evidence stays a ruled list rather than being closed into a radar shape.

A shared-evidence shape is not available.

BenchLM does not draw a radar or infer missing axes when the matched evidence is too sparse.

What each workload costs

Three fixed token mixes turn per-token rates into comparable decisions. Each scenario states context fit and whether cached input had to fall back to the published list-input rate.

Frequently asked questions

Which is better, GLM-5 or GLM-5-Turbo?

GLM-5-Turbo has the higher public score estimate, 65.92 versus 65.24, but the 90% score intervals overlap. The higher estimate is not a decisive winner because the uncertainty ranges overlap.

Which is better for coding, GLM-5 or GLM-5-Turbo?

The published evidence does not provide a shared weighted coding basis for both models, so BenchLM does not name a coding winner.

Which is better for agentic tasks, GLM-5 or GLM-5-Turbo?

The published evidence does not provide a shared weighted agentic tasks basis for both models, so BenchLM does not name a agentic tasks winner.

Which costs less, GLM-5 or GLM-5-Turbo?

For the stated presets, chat costs $0.0026 on GLM-5 and $0.0032 on GLM-5-Turbo; repository review costs $0.0596 and $0.072; the cache-heavy agent loop costs $0.252 and $0.304. GLM-5 does not fit this workload in one request. GLM-5-Turbo does not fit this workload in one request. GLM-5 has no published cached-input rate, so cached tokens use its listed input rate. GLM-5-Turbo has no published cached-input rate, so cached tokens use its listed input rate.

Which has the larger context window, GLM-5 or GLM-5-Turbo?

Both models list the same context window, 200K.
