# Ox Alpha Stealth Model Offers Free 1M-Context Multimodal Access

> The model appears on Nous Portal and Cline without official announcement, providing high capacity access to developers amid questions about its Zhipu origins.

*Published 2026-08-23 · By Marcus Vance*

Ox Alpha is a stealth frontier model developed and operated by an anonymous third-party provider linked to Zhipu AI's GLM series.

Ox Alpha appeared on US developer platforms in August 2026. The model provides free access to advanced capabilities. The context window reaches 1,048,576 tokens. This size enables processing of large inputs. Multimodal support includes text, images, and video. Tool calling allows integration with other systems. The model is listed on OpenRouter as stealth/ox-alpha. The description indicates it is a reasoning model for coding. Sustained agentic work benefits from the large context. Production workloads can use the free access. The release date is August 20, 2026. No official marketing accompanied the listing. The anonymous provider remains unidentified in public statements. Developers have begun to use the model for various tasks. The free pricing lowers the barrier to entry for experimentation. The capacity for high volume usage is notable. The model is available on Nous Portal as well. Cline provides another access point. OpenRouter aggregates the access. The lack of a model card leaves performance details to community testing. The stealth nature adds an element of mystery to the release.

The background of Ox Alpha involves its listing on multiple platforms. Nous Research operates the Nous Portal. The portal lists hundreds of models including Ox Alpha at zero cost. The announcement from Nous Research highlighted the free access for a limited time. The capacity reaches one quadrillion tokens per day. This volume supports widespread use. The model supports multimodal inputs. The context window is specified as 1,048,576 tokens. The model is free on Cline. The model is free on OpenRouter. The community began to investigate the origin. The investigation used API error traces. The traces showed a Java stack trace. The path included paas/v4/chat. This path matches Zhipu official API. The tokenizer behavior showed a difference of exactly 75 tokens from GLM-5.3. The visual token consumption matched GLM-5V-Turbo. These details point to a GLM-5.3 or similar variant. The link to Zhipu AI is based on these matches. No official claim has been made by Zhipu AI. The model remains stealth as of August 23, 2026. The development allows developers to access high end capabilities without cost. The implications for the market include increased competition. The free access may pressure other providers to adjust pricing. The model is designed for coding tasks. The agentic work is supported by the context size. The production workloads can run at scale due to the capacity. The community continues to test the model. The fingerprinting provides strong evidence of the origin. The API path is a key indicator. The token count difference is consistent. The visual token match is perfect. These elements together form the case for the link to Zhipu.

## What technical features distinguish Ox Alpha from other models?

The technical features of Ox Alpha include a context window of 1,048,576 tokens. This is a large window that allows for extensive context retention. The model accepts text inputs.

The sustained agentic work is a target use case. Production workloads are another target. The pricing is zero on the listed platforms. The capacity is one quadrillion tokens per day on Nous Portal. This capacity is significant for high usage. The model is listed on OpenRouter with the description of a reasoning model. The modalities are text, images, and video. The release occurred on August 20, 2026. The stealth status means the provider is anonymous. The model is operated by an anonymous third party. The link to Zhipu is through community analysis. The API error traces provided the first clue. The stack trace contained the specific path. The tokenizer behavior provided additional evidence. The difference of 75 tokens is specific. The visual token consumption matched exactly. These features make the model suitable for complex tasks. The large context supports long conversations or documents. The multimodal support allows for mixed input types. The tool calling enables automation. The free access encourages adoption. The capacity ensures availability for many users. The design focuses on coding and agentic applications. The production workloads can benefit from the scale. The technical details are available on the OpenRouter page. The Nous Portal provides the access interface. The Cline platform offers another entry point. The community has documented the features through testing. The model performs in line with expectations for a frontier model. The absence of an official card means users must verify capabilities themselves. The fingerprinting confirms the likely origin without official confirmation. The technical specifics are consistent across platforms. The context window size is uniform. The modalities are the same. The pricing is zero across the board. The capacity is highlighted in the announcement. The model represents a significant offering in the frontier space.

## How did the community link Ox Alpha to Zhipu AI?

The community linked Ox Alpha to Zhipu AI through several methods. A community developer sent a deliberately malformed API request. The request returned a Java stack trace. The trace contained the path paas/v4/chat. This path matches Zhipu official API path. The tokenizer behavior was analyzed. The token count differed from GLM-5.3 by exactly 75 tokens. This difference is consistent. The visual token consumption was examined. The consumption matched GLM-5V-Turbo perfectly. These matches point to a GLM-5.3 or similar variant. The evidence is based on API responses. The stack trace is a direct indicator. The path is specific to Zhipu. The tokenizer difference is precise. The visual match is exact. The community developer Chetaslua conducted the test. The results were shared in the community. The link is likely but not officially confirmed. Zhipu AI has not claimed the model. The model remains stealth. The analysis provides strong circumstantial evidence. The API path is a key piece. The tokenizer is another. The visual token count is the third. Together they form the case. The community continues to monitor for more evidence. The link helps understand the model capabilities. The GLM series is known for certain performance levels. The variant is likely advanced. The free access may be a test or limited offering. The capacity suggests substantial infrastructure backing the service. The infrastructure behind the model is significant. The community appreciates the access. The investigation was thorough. The methods used are standard for fingerprinting. The results are consistent across tests. The evidence is public in the community. The link is accepted by many as likely. The model is probably a GLM-5.3 variant. The anonymous provider is likely Zhipu or a related entity. The release is stealth to avoid official attribution. The community values the free access. The technical match is convincing. The path match is direct. The token difference is unique. The visual match is perfect. These elements confirm the origin in the view of the community. The analysis was done through API interactions. The malformed request triggered the error. The error revealed the backend. The tokenizer was tested with specific inputs. The visual tokens were counted during image processing. The results aligned with known GLM models. The community shared the findings. The KuCoin report summarized the findings. The details are available for review. The link is the main point of discussion. The model is used despite the stealth status. The capabilities are being explored. The origin provides context for expectations. The GLM series has a reputation for quality. The variant is expected to perform well. The free access is a bonus for developers. The capacity allows for extensive use. The community is active in testing. The fingerprinting is an example of community driven investigation. The methods are reproducible. The results are verifiable. The link is the conclusion from the evidence.
