GLM 5.5 cannot be called today: Z.ai has not announced it, no model ID or price is published, and EvoLink has no route. Z.ai's newest release as of August 14, 2026 is the separate GLM-5.3; this page switches to a live API page only after EvoLink verifies a callable route, model ID, and pricing.
GLM 5.5 API Pricing, Model ID, Context Window, and Limits
These are the fields developers need before integration. No reliable values are available yet; EvoLink will update them only after official publication and route-level verification.
Input and Output Pricing
Input, output, cache, and plan pricing are unpublished. The live EvoLink pricing module will be the source of truth after launch.
Context Window and Maximum Output
No reliable context length, maximum output token limit, or effective long-context result is available.
Regions, Concurrency, and Rate Limits
Regions, concurrency, quotas, rate limits, and 429 behavior require a callable production route.
Currently Available API Providers
No official or aggregator GLM 5.5 route has been verified. EvoLink will update this field after access is live.

What You Will Receive When Access Opens
When access opens we will email you a launch alert, and this page will be updated with the verified model ID, live pricing, API compatibility, regions and limits — plus the path to integrate through EvoLink's unified API while keeping a fallback model.
Is GLM 5.5 Suitable for Coding Agents and Production Apps?
Only real workloads on a real API route can answer that question. These six user-demand metrics are what EvoLink will verify after access opens; they are not confirmed GLM 5.5 capabilities.
Coding Task Completion Rate
Measure whether bug fixes, multi-file refactors, and test tasks actually pass instead of judging one response.
Tool-Call Success and Agent Loops
Track argument errors, repeated calls, unproductive loops, and how often a person must take over.
Effective Long-Context Reliability
Test whether the model keeps constraints, finds evidence, and completes work deep inside large repositories and documents.
Image, Screenshot, and PDF Understanding
Native vision is a frequent request, but input modalities remain unconfirmed and require a model card plus real requests.
Latency, Concurrency, and Reliability
Evaluate time to first token, end-to-end speed, capacity, error rate, and peak-hour 429 responses.
Cost per Accepted Task
Include token use, retries, failed runs, and human correction instead of comparing list prices alone.
How Should You Choose Between GLM 5.5 and GLM-5.3?
There is no verified GLM 5.5 API, price, or test result yet, so teams should not delay a project that can ship on GLM-5.3 today.
Should You Use GLM-5.3 Now?
If delivery matters now, establish a real baseline on the documented and callable GLM-5.3 route.
When Is GLM 5.5 Worth an Upgrade?
Upgrade only when your workloads show a verified improvement in completion rate, reliability, or cost per accepted task.
How Do You Keep Switching and Fallback Simple?
Keep the current model behind EvoLink's unified API, then add GLM 5.5 after validation without rebuilding another provider integration.
Other text models on EvoLink besides GLM 5.5
All three are callable on EvoLink today; use them as the baseline until a GLM 5.5 route is verified.

GLM 5.5 API FAQ
Has Z.ai officially announced GLM 5.5?
No official Z.ai announcement or model card exists as of August 14, 2026 — the model Z.ai released that day was the separate GLM-5.3. GLM 5.5 naming and timing remain based on third-party reporting.
Is the next model GLM-5.3, GLM 5.5, or GLM-6?
Z.ai released GLM-5.3 on August 14, 2026 — that answers it for the current generation. GLM 5.5 has not been announced; it is expected, if it comes, as a later release and is tracked here as a separate entity.
Is GLM 5.5 available on EvoLink?
No. EvoLink has not published a callable route, model ID, pricing, or production support claim for GLM 5.5.
When will GLM 5.5 be released?
There is no announced date. The August 2026 forecast window produced a release — but it was GLM-5.3, not GLM 5.5. GLM 5.5 remains unannounced.
What is the GLM 5.5 model ID?
No official request model ID is published. Do not infer one from the page slug or GLM-5.3.
How much will the GLM 5.5 API cost?
Pricing is not published. This page will use EvoLink's live pricing module only after the route and SKUs are approved.
Will GLM 5.5 be open weight?
That is not confirmed. GLM-5.3's license does not prove that a future release will use the same terms.
Will GLM 5.5 support images, screenshots, or PDFs?
Native vision is a frequent community request, but Z.ai has not confirmed the input modalities for its next model.
Should teams replace GLM-5.3 now?
No. Keep the supported GLM-5.3 route until GLM 5.5 has comparable facts and passes offline, shadow, canary, and rollback gates.
What does the EvoLink waitlist provide?
A notification after EvoLink verifies the official release, model ID, pricing, route behavior, and access state.
