Cloudflare developer platform and API changelog updates

Cloudflare API Changelog Monitoring

Cloudflare changes can impact edge behavior, DNS workflows, security automation, and API-driven infrastructure management. This Cloudflare API Changelog Monitoring page gives teams one place to review new platform updates and assess operational risk quickly.

Effective Cloudflare API Changelog Monitoring gives infrastructure teams earlier visibility into changes that might influence deployment flows, zone automation, or security controls. The result is a tighter response loop when something needs testing, rollout planning, or internal communication.

The benefit of Cloudflare API Changelog Monitoring is simple: your team gets a repeatable way to watch changes, evaluate risk, and act before small upstream updates turn into customer-facing bugs. Cloudflare developer platform and API changelog updates

Cloudflare API down?

Cloudflare API down? Soon we will add direct API status monitoring alongside Cloudflare API Changelog Monitoring. For now, go to the official API status page on the Cloudflare website. In the future, we plan to detect potential outages even before the public status page is updated.

Workers AI - Z.ai GLM-5.3 now available on Workers AI

@cf/zai-org/glm-5.3 is now available on Workers AI. It is Z.ai's flagship agentic coding model, built for long-running, tool-driven development workflows rather than single-turn chat. GLM-5.3 uses the same base model as GLM-5.2, with every gain coming from post-training. The results are substantial on coding and agentic benchmarks: Z.ai reports ↗ a 50% improvement over GLM-5.2 on its in-house Z.ai Code Bench, and calls GLM-5.3 the most capable open-weights model for coding. On public benchmarks, it scores 88.2 on Terminal Bench 2.1 (up from 81.0), 28.3 on Terminal Bench 3.0 — open-source state of the art, up from 4.6 — 66.9 on DeepSWE (up from 46.2), 78.1 on FrontierSWE (up from 67.5), and 42.5 on SWE-Marathon (up from 19.4). It is also the top-scoring model in Z.ai's comparisons on CyberGym for vulnerability discovery (84.5) and on long-horizon automation tasks like AutomationBench (48.2). The price-to-performance ratio is the compelling part. On Workers AI, GLM-5.3 costs the same as GLM-5.2 — $1.40 per M input tokens, $0.26 per M cached input tokens, and $4.40 per M output tokens — while roughly doubling GLM-5.2's scores on long-horizon benchmarks like SWE-Marathon, and improving them by more than 6x on Terminal Bench 3.0. GLM-5.3 requires the Workers Paid plan or prepaid AI Gateway credits. Use GLM-5.3 through the Workers AI binding (env.AI.run()), the REST API, the OpenAI-compatible endpoint, or AI Gateway. For more information, refer to the GLM-5.3 model page and pricing.

Workers, Durable Objects - Durable Objects can use up to ten Dynamic Workers concurrently

Durable Objects can have up to ten distinct Dynamic Workers with in-flight requests, increased from four. This limit applies across all concurrent requests to the same Durable Object because they share an input/output (I/O) context. Other Workers can have up to four distinct Dynamic Workers with in-flight requests per request. Multiple in-flight requests to the same Dynamic Worker count as one toward this limit. For more information, refer to Dynamic Workers limits.

Access - Access service token secrets use a scannable format

Cloudflare Access service token Client Secrets created on or after August 26, 2026, use the format cfast_[40 alphanumeric characters][8-character checksum]. The prefix and checksum make these credentials easier for secret scanning tools to identify with fewer false positives. Existing service token secrets continue to work and do not require rotation. Both formats use the same Client ID and the same CF-Access-Client-Id and CF-Access-Client-Secret authentication headers. For more information, refer to Service tokens.

AI Search - New Workers AI text generation models in AI Search

AI Search now supports six additional Workers AI models for text generation: Model Context window (tokens) @cf/deepseek-ai/deepseek-v4-flash-0731 1,048,576 @cf/deepseek-ai/deepseek-v4-pro-0813 1,048,576 @cf/openai/gpt-oss-120b 128,000 @cf/openai/gpt-oss-20b 128,000 @cf/qwen/qwen3.8-27b 262,144 @cf/moonshotai/kimi-k2.7-code 262,144 These models run on Workers AI, so they do not require an additional provider key. Select a model when creating or updating an AI Search instance in the dashboard or through the API. For the full list of supported models, refer to Supported models.

Flagship - Create app-scoped API tokens for Flagship

You can now create app-scoped API tokens for Flagship. These tokens grant access only to the Flagship apps you select, instead of every app in the account. When you create a custom token, open the resource dropdown (it defaults to Entire Account) and select Specified Flagship apps. Then choose the app and a Flagship App permission: Evaluate, Read, or Write. Account-wide Flagship Evaluate, Read, and Write permissions still exist when you need access to every app. Use app-scoped tokens in trusted server-side environments, such as Wrangler, CI, or a backend service that should only touch one app. To create a token, refer to API tokens or open the app-scoped token form ↗ in the dashboard.

Log Explorer - Delete Log Explorer datasets

Cloudflare Log Explorer customers can now permanently delete account and zone datasets from the Cloudflare dashboard or API. Deletion protection is enabled by default to prevent accidental data loss. In the dashboard, go to Manage datasets, disable deletion protection for the dataset, select Delete, and enter the dataset name to confirm. To delete a dataset through the API, first set deletion_protection to false with the Update an account or zone dataset method. Then use the Delete an account or zone dataset method. Dataset deletion is irreversible and runs asynchronously. You cannot recreate the same dataset while deletion is in progress.
