AI Search now offers new REST API endpoints for search and chat that use an OpenAI compatible format. This means you can use the familiar messages array structure that works with existing OpenAI SDKs and tools. The messages array also lets you pass previous messages within a session, so the model can maintain context across multiple turns.
Endpoint
Path
Chat Completions
POST /accounts/{account_id}/ai-search/instances/{name}/chat/completions
Search
POST /accounts/{account_id}/ai-search/instances/{name}/search
Here is an example request to the Chat Completions endpoint using the new messages array format:
curl https://api.cloudflare.com/client/v4/accounts/{ACCOUNT_ID}/ai-search/instances/{NAME}/chat/completions \ -H "Content-Type: application/json" \ -H "Authorization: Bearer {API_TOKEN}" \ -d '{ "messages": [ { "role": "system", "content": "You are a helpful documentation assistant." }, { "role": "user", "content": "How do I get started?" } ] }'
If you are using the previous AutoRAG API endpoints (/autorag/rags/), we recommend migrating to the new endpoints. The previous AutoRAG API endpoints will continue to be fully supported.
Select your instance, and turn on Public Endpoint in Settings.
For more details, refer to Public endpoint configuration.
UI snippets
UI snippets are pre-built search and chat components you can embed in your website. Visit search.ai.cloudflare.com ↗ to configure and preview components for your AI Search instance.
AI Search now supports custom metadata filtering, allowing you to define your own metadata fields and filter search results based on attributes like category, version, or any custom field you define.
Define a custom metadata schema
You can define up to 5 custom metadata fields per AI Search instance. Each field has a name and data type (text, number, or boolean):
Two new fields are now available in the httpRequestsAdaptive and httpRequestsAdaptiveGroupsGraphQL Analytics API datasets:
webAssetsOperationId — the ID of the saved endpoint that matched the incoming request.
webAssetsLabelsManaged — the managed labels mapped to the matched operation at the time of the request (for example, cf-llm, cf-log-in). At most 10 labels are returned per request.
Both fields are empty when no operation matched. webAssetsLabelsManaged is also empty when no managed labels are assigned to the matched operation.
These fields allow you to determine, per request, which Web Assets operation was matched and which managed labels were active. This is useful for troubleshooting downstream security detection verdicts — for example, understanding why AI Security for Apps did or did not flag a request.
R2 SQL now supports an expanded SQL grammar so you can write richer analytical queries without exporting data. This release adds CASE expressions, column aliases, arithmetic in clauses, 163 scalar functions, 33 aggregate functions, EXPLAIN, Common Table Expressions (CTEs),and full struct/array/map access. R2 SQL is Cloudflare's serverless, distributed, analytics query engine for querying Apache Iceberg ↗ tables stored in R2 Data Catalog. This page documents the supported SQL syntax.
Highlights
Column aliases — SELECT col AS alias now works in all clauses
CASE expressions — conditional logic directly in SQL (searched and simple forms)
Scalar functions — 163 new functions across math, string, datetime, regex, crypto, encoding, and type inspection categories
Aggregate functions — statistical (variance, stddev, correlation, regression), bitwise, boolean, and positional aggregates join the existing basic and approximate functions
Complex types — query struct fields with bracket notation, use 46 array functions, and extract map keys/values
Common table expressions (CTEs) — use WITH ... AS to define named temporary result sets. Chained CTEs are supported. All CTEs must reference the same single table.
Full expression support — arithmetic, type casting (CAST, TRY_CAST, :: shorthand), and EXTRACT in SELECT, WHERE, GROUP BY, HAVING, and ORDER BY
Examples
CASE expressions with statistical aggregates
SELECT source, CASE WHEN AVG(price) > 30 THEN 'premium' WHEN AVG(price) > 10 THEN 'mid-tier' ELSE 'budget' END AS tier, round(stddev(price), 2) AS price_volatility, approx_percentile_cont(price, 0.95) AS p95_priceFROM my_namespace.sales_dataGROUP BY source
Struct and array access
SELECT product_name, pricing['price'] AS price, array_to_string(tags, ', ') AS tag_listFROM my_namespace.productsWHERE array_has(tags, 'Action')ORDER BY pricing['price'] DESCLIMIT 10
Chained CTEs with time-series analysis
WITH monthly AS ( SELECT date_trunc('month', sale_timestamp) AS month, department, COUNT(*) AS transactions, round(AVG(total_amount), 2) AS avg_amount FROM my_namespace.sales_data WHERE sale_timestamp BETWEEN '2025-01-01T00:00:00Z' AND '2025-12-31T23:59:59Z' GROUP BY date_trunc('month', sale_timestamp), department),ranked AS ( SELECT month, department, transactions, avg_amount, CASE WHEN avg_amount > 1000 THEN 'high-value' WHEN avg_amount > 500 THEN 'mid-value' ELSE 'standard' END AS tier FROM monthly WHERE transactions > 100)SELECT * FROM rankedORDER BY month, avg_amount DESC
This rule has been merged into the original rule "PHP, vBulletin, jQuery File Upload - Code Injection, Dangerous File Upload - CVE:CVE-2018-9206, CVE:CVE-2019-17132" (ID: )
Cloudflare Access supports managed OAuth, which allows non-browser clients — such as CLIs, AI agents, SDKs, and scripts — to authenticate with Access-protected applications using a standard OAuth 2.0 authorization code flow.
Previously, non-browser clients that attempted to access a protected application received a 302 redirect to a login page they could not complete. The established workaround was cloudflared access curl, which required installing additional tooling.
With managed OAuth, clients instead receive a 401 response with a WWW-Authenticate header that points to Access's OAuth discovery endpoints (RFC 8414 ↗ and RFC 9728 ↗). The client opens the end user's browser to the Access login page. The end user authenticates with their identity provider, and the client receives an OAuth access token for subsequent requests.
Access enforces the same policies as a browser login; the OAuth layer is a new transport mechanism, not a separate authentication path.
Managed OAuth can be enabled on any self-hosted Access application or MCP server portal. It is opt-in for existing applications to avoid interfering with those that run their own OAuth servers and rely on their own WWW-Authenticate headers.
To enable managed OAuth, go to Zero Trust > Access controls > Applications, edit the application, and turn on Managed OAuth under Advanced settings.
You can also enable it via the API by setting oauth_configuration.enabled to true on the Access applications endpoint.
When Gateway routing is turned on, portal traffic appears in your Gateway HTTP logs. You can create Gateway HTTP policies with DLP profiles to detect and block sensitive data sent to upstream MCP servers.
To enable Gateway routing, go to Access controls > AI controls, edit the portal, and turn on Route traffic through Cloudflare Gateway under Basic information.
DNS Analytics is now available for customers with Customer Metadata Boundary (CMB) set to EU. Query your DNS analytics data while keeping metadata stored in the EU region.
This update includes:
DNS Analytics — Access the same DNS analytics experience for zones in CMB=EU accounts.
EU data residency — Analytics data is stored and queried from the EU region, meeting data localization requirements.
DNS Firewall Analytics — DNS Firewall analytics is now supported for CMB=EU customers.
Availability
Available to customers with the Data Localization Suite who have Customer Metadata Boundary configured for the EU region.
Where to find it
Authoritative DNS: In the Cloudflare dashboard, select your zone and go to the Analytics page.
In the Cloudflare One dashboard, the overview page for a specific Cloudflare Tunnel now shows all replicas of that tunnel and supports streaming logs from multiple replicas at once.
Previously, you could only stream logs from one replica at a time. With this update:
Replicas on the tunnel overview — All active replicas for the selected tunnel now appear on that tunnel's overview page under Connectors. Select any replica to stream its logs.
Multi-connector log streaming — Stream logs from multiple replicas simultaneously, making it easier to correlate events across your infrastructure during debugging or incident response. To try it out, log in to Cloudflare One ↗ and go to Networks > Connectors > Cloudflare Tunnels. Select View logs next to the tunnel you want to monitor.
Each VPC Service now has a Metrics tab so you can monitor connection health and debug failures without leaving the dashboard.
Connections — See successful and failed connections over time, broken down by what is responsible: your origin (Bad Upstream), your configuration (Client), or Cloudflare (Internal).
Latency — Track connection and DNS resolution latency trends.
Errors — Drill into specific error codes grouped by category, with filters to isolate upstream, client, or internal failures.
You can also view and edit your VPC Service configuration, host details, and port assignments from the Settings tab.
For a full list of error codes and what they mean, refer to Troubleshooting.
Hyperdrive now supports custom TLS/SSL certificates for MySQL databases, bringing the same certificate options previously available for PostgreSQL to MySQL connections.
You can now configure:
Server certificate verification with VERIFY_CA or VERIFY_IDENTITY SSL modes to verify that your MySQL database server's certificate is signed by the expected certificate authority (CA).
Client certificates (mTLS) for Hyperdrive to authenticate itself to your MySQL database with credentials beyond username and password.
Create a Hyperdrive configuration with custom certificates for MySQL:
# Upload a CA certificatenpx wrangler cert upload certificate-authority --ca-cert your-ca-cert.pem --name your-custom-ca-name# Create a Hyperdrive with VERIFY_IDENTITY modenpx wrangler hyperdrive create your-hyperdrive-config \ --connection-string="mysql://user:password@hostname:port/database" \ --ca-certificate-id <CA_CERT_ID> \ --sslmode VERIFY_IDENTITY
You can now manage Cloudflare Tunnels directly from Wrangler, the CLI for the Cloudflare Developer Platform. The new wrangler tunnel commands let you create, run, and manage tunnels without leaving your terminal.
Available commands:
wrangler tunnel create — Create a new remotely managed tunnel.
wrangler tunnel list — List all tunnels in your account.
wrangler tunnel info — Display details about a specific tunnel.
wrangler tunnel delete — Delete a tunnel.
wrangler tunnel run — Run a tunnel using the cloudflared daemon.
wrangler tunnel quick-start — Start a free, temporary tunnel without an account using Quick Tunnels.
Wrangler handles downloading and managing the cloudflared binary automatically. On first use, you will be prompted to download cloudflared to a local cache directory.
These commands are currently experimental and may change without notice.
Workers AI is officially in the big models game. @cf/moonshotai/kimi-k2.5 is the first frontier-scale open-source model on our AI inference platform — a large model with a full 256k context window, multi-turn tool calling, vision inputs, and structured outputs. By bringing a frontier-scale model directly onto the Cloudflare Developer Platform, you can now run the entire agent lifecycle on a single, unified platform.
The model has proven to be a fast, efficient alternative to larger proprietary models without sacrificing quality. As AI adoption increases, the volume of inference is skyrocketing — now you can access frontier intelligence at a fraction of the cost.
Key capabilities
256,000 token context window for retaining full conversation history, tool definitions, and entire codebases across long-running agent sessions
Multi-turn tool calling for building agents that invoke tools across multiple conversation turns
Vision inputs for processing images alongside text
Structured outputs with JSON mode and JSON Schema support for reliable downstream parsing
Function calling for integrating external tools and APIs into agent workflows
Prefix caching and session affinity
When an agent sends a new prompt, it resends all previous prompts, tools, and context from the session. The delta between consecutive requests is usually just a few new lines of input. Prefix caching avoids reprocessing the shared context, saving time and compute from the prefill stage. This means faster Time to First Token (TTFT) and higher Tokens Per Second (TPS) throughput.
Workers AI has done prefix caching, but we are now surfacing cached tokens as a usage metric and offering a discount on cached tokens compared to input tokens (pricing is listed on the model page).
curl -X POST \ "https://api.cloudflare.com/client/v4/accounts/{account_id}/ai/run/@cf/moonshotai/kimi-k2.5" \ -H "Authorization: Bearer {api_token}" \ -H "Content-Type: application/json" \ -H "x-session-affinity: ses_12345678" \ -d '{ "messages": [ { "role": "system", "content": "You are a helpful assistant." }, { "role": "user", "content": "What is prefix caching and why does it matter?" } ], "max_tokens": 2400, "stream": true }'
Some clients like OpenCode ↗ implement session affinity automatically. The Agents SDK ↗ starter also sets up the wiring for you.
Redesigned asynchronous API
For volumes of requests that exceed synchronous rate limits, you can submit batches of inferences to be completed asynchronously. We have revamped the Asynchronous Batch API with a pull-based system that processes queued requests as soon as capacity is available. With internal testing, async requests usually execute within 5 minutes, but this depends on live traffic.
The async API is the best way to avoid capacity errors in durable workflows. It is ideal for use cases that are not real-time, such as code scanning agents or research agents.
To use the asynchronous API, pass queueRequest: true:
// 1. Push a batch of requests into the queueconst res = await env.AI.run( "@cf/moonshotai/kimi-k2.5", { requests: [ { messages: [{ role: "user", content: "Tell me a joke" }], }, { messages: [{ role: "user", content: "Explain the Pythagoras theorem" }], }, ], }, { queueRequest: true },);// 2. Grab the request IDconst requestId = res.request_id;// 3. Poll for the resultconst result = await env.AI.run("@cf/moonshotai/kimi-k2.5", { request_id: requestId,});if (result.status === "queued" || result.status === "running") { // Retry by polling again} else { return Response.json(result);}
You can also set up event notifications to know when inference is complete instead of polling.
Cloudflare dashboard SCIM provisioning now supports Authentik ↗ as an identity provider, joining Okta and Microsoft Entra ID as explicitly supported providers.
Customers can now sync users and group information from Authentik to Cloudflare, apply Permission Policies to those groups, and manage the lifecycle of users & groups directly from your Authentik Identity Provider.
Cloudflare dashboard SCIM provisioning operations are now captured in Audit Logs v2, giving you visibility into user and group changes made by your identity provider.
The cf.timings.worker_msec field is now available in the Ruleset Engine. This field reports the wall-clock time that a Cloudflare Worker spent handling a request, measured in milliseconds.
You can use this field to identify slow Worker executions, detect performance regressions, or build rules that respond differently based on Worker processing time, such as logging requests that exceed a latency threshold.
Field details

Description
cf.timings.worker_msec
Integer
The time spent executing a Cloudflare Worker in milliseconds. Returns 0 if no Worker was invoked.
We are introducing Logo Match Preview, bringing the same pre-save visibility to visual assets that was previously only available for string-based queries. This update allows you to fine-tune your brand detection strategy before committing to a live monitor.
What’s new:
Upload your brand logo and immediately see a sample of potential matches from recently detected sites before finalizing the query
Adjust your similarity score (from 75% to 100%) and watch the results refresh in real-time to find the balance between broad detection and noise reduction
Review the specific logos triggered by your current settings to ensure your query is capturing the right level of brand infringement
You can now use a Workers binding to transform videos with Media Transformations. This allows you to resize, crop, extract frames, and extract audio from videos stored anywhere, even in private locations like R2 buckets.
The Media Transformations binding is useful when you want to:
Transform videos stored in private or protected sources
Optimize videos and store the output directly back to R2 for re-use
Extract still frames for classification or description with Workers AI
Extract audio tracks for transcription using Workers AI
To get started, add the Media binding to your Wrangler configuration:
The latest releases of @cloudflare/codemode ↗ add a new MCP barrel export, remove ai and zod as required peer dependencies from the main entry point, and give you more control over the sandbox.
New @cloudflare/codemode/mcp export
A new @cloudflare/codemode/mcp entry point provides two functions that wrap MCP servers with Code Mode:
codeMcpServer({ server, executor }) — wraps an existing MCP server with a single code tool where each upstream tool becomes a typed codemode.* method.
openApiMcpServer({ spec, executor, request }) — creates search and execute MCP tools from an OpenAPI spec with host-side request proxying and automatic $ref resolution.
import { codeMcpServer } from "@cloudflare/codemode/mcp";import { DynamicWorkerExecutor } from "@cloudflare/codemode";const executor = new DynamicWorkerExecutor({ loader: env.LOADER });// Wrap an existing MCP server — all its tools become// typed methods the LLM can call from generated codeconst server = await codeMcpServer({ server: upstreamMcp, executor });
import { codeMcpServer } from "@cloudflare/codemode/mcp";import { DynamicWorkerExecutor } from "@cloudflare/codemode";const executor = new DynamicWorkerExecutor({ loader: env.LOADER });// Wrap an existing MCP server — all its tools become// typed methods the LLM can call from generated codeconst server = await codeMcpServer({ server: upstreamMcp, executor });
Zero-dependency main entry point
Breaking change in v0.2.0:generateTypes and the ToolDescriptor / ToolDescriptors types have moved to @cloudflare/codemode/ai:
// Beforeimport { generateTypes } from "@cloudflare/codemode";// Afterimport { generateTypes } from "@cloudflare/codemode/ai";
// Beforeimport { generateTypes } from "@cloudflare/codemode";// Afterimport { generateTypes } from "@cloudflare/codemode/ai";
The main entry point (@cloudflare/codemode) no longer requires the ai or zod peer dependencies. It now exports:
Export
Description
sanitizeToolName
Sanitize tool names into valid JS identifiers
normalizeCode
Normalize LLM-generated code into async arrow functions
generateTypesFromJsonSchema
Generate TypeScript type definitions from plain JSON Schema
jsonSchemaToType
Convert a single JSON Schema to a TypeScript type string
DynamicWorkerExecutor
Sandboxed code execution via Dynamic Worker Loader
ToolDispatcher
RPC target for dispatching tool calls from sandbox to host
The ai and zod peer dependencies are now optional — only required when importing from @cloudflare/codemode/ai.
Custom sandbox modules
DynamicWorkerExecutor now accepts an optional modules option to inject custom ES modules into the sandbox:
const executor = new DynamicWorkerExecutor({ loader: env.LOADER, modules: { "utils.js": `export function add(a, b) { return a + b; }`, },});// Sandbox code can then: import { add } from "utils.js"
const executor = new DynamicWorkerExecutor({ loader: env.LOADER, modules: { "utils.js": `export function add(a, b) { return a + b; }`, },});// Sandbox code can then: import { add } from "utils.js"
Internal normalization and sanitization
DynamicWorkerExecutor now normalizes code and sanitizes tool names internally. You no longer need to call normalizeCode() or sanitizeToolName() before passing code and functions to execute().
AI Gateway now supports the cf-aig-collect-log-payload header, which controls whether request and response bodies are stored in logs. By default, this header is set to true and payloads are stored alongside metadata. Set this header to false to skip payload storage while still logging metadata such as token counts, model, provider, status code, cost, and duration.
This is useful when you need usage metrics but do not want to persist sensitive prompt or response data.
curl https://gateway.ai.cloudflare.com/v1/$ACCOUNT_ID/$GATEWAY_ID/openai/chat/completions \ --header "Authorization: Bearer $TOKEN" \ --header 'Content-Type: application/json' \ --header 'cf-aig-collect-log-payload: false' \ --data '{ "model": "gpt-4o-mini", "messages": [ { "role": "user", "content": "What is the email address and phone number of user123?" } ] }'
The Security Overview has been updated to provide Application Security customers with more actionable insights and a clearer view of their security posture.
Key improvements include:
Criticality for all Insights: Every insight now includes a criticality rating, allowing you to prioritize the most impactful security action items first.
Detection Tools Section: A new section displays the security detection tools available to you, indicating which are currently enabled and which can be activated to strengthen your defenses.
Industry Peer Comparison (Enterprise customers): A new module from Security Reports benchmarks your security posture against industry peers, highlighting relative strengths and areas for improvement.
You can now set topK up to 50 when a Vectorize query returns values or full metadata. This raises the previous limit of 20 for queries that use returnValues: true or returnMetadata: "all".
Use the higher limit when you need more matches in a single query response without dropping values or metadata. Refer to the Vectorize API reference for query options and current topK limits.
Investigations now support unlimited result paging in both the dashboard and the API, removing the previous 1,000-record cap. Security teams can page through complete result sets when searching across large mail volumes, giving SOC analysts and automated workflows deeper visibility for forensics and threat hunting.
In the dashboard, infinite paging is now supported in the Investigations view. The 1,000-record ceiling has been removed, so you can navigate through the full result set directly in the UI. The Investigations API now returns up to 10,000 records per page (up from 1,000), with no cap on total result volume across pages.
For high-volume use cases, we recommend:
Logpush to a SIEM for full-fidelity datasets and long-term retention.
SOAR playbooks against the async bulk action API for large-scale remediation. Bulk actions initiated from the dashboard remain capped at 1,000 messages per action.
The Investigations API for report exports larger than 1,000 results, which is the dashboard download cap.
