ERNIE 5.0 vs GLM 5

Baidu · China  |  Z.ai · China · Updated June 2026

Quick verdict

Pick ERNIE 5.0 for baidu's flagship omni-modal model — text, image and video understanding or particularly strong on chinese-language reasoning tasks. Pick GLM 5 for agentic planning and long-horizon coding workflows or complex systems design and backend reasoning. Choose GLM 5 if you need self-hosting or data privacy; ERNIE 5.0 if you want a managed API.

ERNIE 5.0 (Baidu) and GLM 5 (Z.ai) are two of the models people most often weigh against each other in 2026. ERNIE 5.0 is baidu's flagship omni-modal ERNIE model — strong Chinese-language and multimodal reasoning at low cost, though it trails the Western frontier on independent benchmarks. GLM 5 is z.ai's flagship open-weight (MIT) MoE foundation model, engineered for complex systems design and long-horizon agentic coding. They diverge most on price, context window and open vs. closed weights — each quantified below from the models' real specs.

Who wins what

Baidu's flagship omni-modal model — text, image and video understanding

ERNIE 5.0

Baidu's flagship omni-modal ERNIE model — strong Chinese-language and multimodal reasoning at low cost, though it trails the Western frontier on independent benchmarks — and it runs cheaper at $0.6/$2.1 per 1M tokens.

Particularly strong on Chinese-language reasoning tasks

ERNIE 5.0

ERNIE 5.0 lists particularly strong on Chinese-language reasoning tasks among its strengths; GLM 5 does not.

Competitive API pricing (around $0.60/$2.10 per million tokens)

ERNIE 5.0

ERNIE 5.0 lists competitive API pricing (around $0.60/$2.10 per million tokens) among its strengths; GLM 5 does not.

Agentic planning and long-horizon coding workflows

GLM 5

Its 200K window holds about 1.6× more than ERNIE 5.0's 128K in a single prompt.

Complex systems design and backend reasoning

GLM 5

Z.ai's flagship open-weight (MIT) MoE foundation model, engineered for complex systems design and long-horizon agentic coding — and it carries the larger 200K context.

Iterative self-correction on autonomous tasks

GLM 5

Z.ai's flagship open-weight (MIT) MoE foundation model, engineered for complex systems design and long-horizon agentic coding — and its weights are open while ERNIE 5.0 is API-only.

Lowest cost at scale

ERNIE 5.0

At $0.6/$2.1 per 1M tokens, it is the cheaper of the two — the gap dominates the bill on high-volume workloads.

Largest single-prompt input

GLM 5

Its 200K window is about 1.6× larger than ERNIE 5.0's 128K, fitting roughly 300 pages in one prompt.

Which should you pick?

A cost-sensitive startup shipping high volume

ERNIE 5.0

At $0.6/$2.1 per 1M tokens it undercuts GLM 5, and on millions of tokens that margin decides the monthly bill.

Someone analysing very long documents or codebases

GLM 5

Larger 200K window fits more in one prompt.

A team with data-privacy or self-hosting needs

GLM 5

Open weights let you run it on your own hardware; ERNIE 5.0 is API-only.

Anyone whose priority is baidu's flagship omni-modal model — text, image and video understanding

ERNIE 5.0

It is specifically built for that.

Anyone whose priority is agentic planning and long-horizon coding workflows

GLM 5

That is its strongest area.

ERNIE 5.0: where it fits

Baidu's flagship omni-modal ERNIE model — strong Chinese-language and multimodal reasoning at low cost, though it trails the Western frontier on independent benchmarks. Released January 22, 2026 by Baidu, it is built for baidu's flagship omni-modal model — text, image and video understanding, particularly strong on Chinese-language reasoning tasks, competitive API pricing (around $0.60/$2.10 per million tokens), and backed by a major lab with deep China-market integration.

Its trade-offs are real: trails the Western frontier on aggregate independent tests (AA Intelligence Index ~22 for the tracked Thinking Preview), parameter and architecture details are vendor-stated and opaque, closed weights on a China-hosted API, and 128K context is smaller than 1M-token rivals. At $0.6 in / $2.1 out per million tokens, it sits in the budget price band.

GLM 5: where it fits

Z.ai's flagship open-weight (MIT) MoE foundation model, engineered for complex systems design and long-horizon agentic coding. Released February 11, 2026 by Z.ai, it is built for agentic planning and long-horizon coding workflows, complex systems design and backend reasoning, iterative self-correction on autonomous tasks, and open weights under the permissive MIT license.

Its trade-offs: 200K context trails 1M-context rivals, and quickly superseded by GLM-5.1 and GLM-5.2. At $1 in / $3.2 out per million tokens, it sits in the budget price band.

The bottom line for this matchup

The defining split here is open vs. closed. GLM 5 gives you weights you control — self-host it, fine-tune it, keep data in-house, pay only for hardware. ERNIE 5.0 gives you a managed, always-updated API with no infrastructure to run. Teams with GPUs, privacy requirements, or huge volume often favour the open model; teams that want zero ops and the latest capabilities favour the closed one. Capability is close enough that this operational question, not the benchmark, usually decides it.

Frequently asked questions

Is ERNIE 5.0 or GLM 5 better for coding?

Public SWE-Bench figures are not available for ERNIE 5.0, so the honest test is your own repository — run an identical real bug through both. By design, ERNIE 5.0 leans toward baidu's flagship omni-modal model — text, image and video understanding while GLM 5 leans toward agentic planning and long-horizon coding workflows, and that positioning usually predicts which feels better on your codebase.

Which is cheaper, ERNIE 5.0 or GLM 5?

GLM 5 is open-weight, so self-hosting means no per-token fee (you pay for hardware instead), while ERNIE 5.0 is API-metered at $0.6/$2.1 per 1M tokens. For most teams without GPUs, the API model is cheaper to start; at very high volume, self-hosting can win.

Which has the bigger context window?

GLM 5 — 200K vs 128K, about 1.6× larger. Useful only if the model actually reasons over the full window, which not all do.

Can I use both ERNIE 5.0 and GLM 5 together?

Yes — a multi-model platform like LumiChats gives you ERNIE 5.0, GLM 5 and 40+ others under one ₹69/day pass (about $1/day), so you can draft with one and cross-check with the other instead of buying two subscriptions.

Which is newer, ERNIE 5.0 or GLM 5?

GLM 5 — released February 11, 2026, about 20 days after ERNIE 5.0.
