Elastic’s September 2026 DevRel newsletter details several developer-facing updates, including access to the jina-ocr-v1 document parser, a technical-preview command-line interface for Elastic APIs, and expanded observability for AI applications. The same update describes an internal audit of 13 million AI-agent tool events collected from more than 1,100 developer machines.
OCR across complex pages
jina-ocr-v1 is available through the Elastic Inference Service and other Jina access paths, with local or on-premises deployment also described. The 3.4-billion-parameter mixture-of-experts model activates 570 million parameters at inference time and returns structured Markdown from scanned pages, document photos, slides and handwritten notes. Tables are represented as HTML and mathematical formulas as LaTeX. Elastic says it supports more than 100 languages and mixed-language pages in one pass.
Elastic reports scores of 83.4 on olmOCR-bench and 91.14 on OmniDocBench, comparing the latter with GPT-5.2’s 86.59. Those are company-provided benchmark claims, not independent test results. The downloadable model is under CC BY-NC 4.0, while commercial deployments can use Jina On-Prem. Native PDF support for the Elastic inference endpoint is described as coming soon.
A controlled API entry point
The Elastic CLI is in technical preview and provides one command-line entry point for public Elasticsearch, Kibana and Elastic Cloud APIs. It accepts and emits JSON, validates requests against schemas before network calls, and supports dry runs. Credentials are stored through the operating system keychain, while allowlists, blocklists and explicit confirmation requirements can restrict agent actions.
Elastic Agent Skills now use the CLI as their transport, separating instructions about Elasticsearch operations from the mechanics of authentication and execution. The update lists skills for Elastic Cloud onboarding, Elastic Workflows and Kubernetes investigation as available, with additional areas still in progress.
Tracing and agent oversight
Elastic APM’s GenAI spans can display prompts, inputs, responses and per-call token counts in the trace view when an OpenTelemetry-instrumented application emits the relevant attributes. The feature is in technical preview on Serverless, with Stack 9.6 support described as coming next, and follows OpenTelemetry GenAI semantic conventions v1.37.0 or later.
Separately, Elastic Security Labs says it collected 13 million Cursor hook events across more than 1,100 machines. The sensor recorded actions such as file reads, shell execution and MCP calls; Elastic reports that file reads outnumbered shell commands roughly four to one and that more than 300 MCP servers appeared in the data. The setup observes activity by default, although blocking hooks can add approval gates.
