What is Docling?

Docling ships a native PDF pipeline and Apple Pages support while maturing its VLM integration layer.

Docling is releasing almost daily, expanding its supported document format surface with each version. Recent additions include a native PDF pipeline, completed Apple Pages support, JATS external hyperlinks, LaTeX output, and CUDA support for RapidOCR on ONNX Runtime. Threaded docling-parse is now the default, and VLM backends (Chandra, Unlimited-OCR) are getting tighter version management and error handling.

What is opencode?

OpenCode ships daily with GPT-6/Astra support, Claude 5.1 thinking blocks, and Azure enterprise auth

OpenCode is shipping daily-to-weekly micro-releases with a tight focus on multi-provider reliability. GPT-6/Astra system prompt support, Claude 5.1 thinking block binding, and Azure Entra ID CLI sign-in all landed in the past two weeks. Each release also includes fixes for specific model providers (Bedrock DeepSeek, OpenAI compatibility, Cloudflare AI Gateway routing), reflecting the maintenance cost of maintaining a wide provider compatibility surface as that surface keeps expanding with new models.

Docling

5.0

Docling ships a native PDF pipeline and Apple Pages support while maturing its VLM integration layer.

◆ Current state

Docling is releasing almost daily, expanding its supported document format surface with each version. Recent additions include a native PDF pipeline, completed Apple Pages support, JATS external hyperlinks, LaTeX output, and CUDA support for RapidOCR on ONNX Runtime. Threaded docling-parse is now the default, and VLM backends (Chandra, Unlimited-OCR) are getting tighter version management and error handling.

◆ Where it's heading

Docling is converging on a universal document parsing pipeline — every major format (PDF, DOCX, PPTX, Apple Pages, AsciiDoc, WebVTT, EBCDIC, JATS) processed through a single interface, with multiple output formats (Markdown, JSON, LaTeX). The VLM integration is moving from experimental to production-ready as the team adds CUDA hardware support, min-version enforcement, and format-specific model handling. Scientific document workflows are an emerging target given the LaTeX output and JATS support.

◆ Prediction

The experimental two-stage VLM pipeline will stabilize into a production path in the next few releases. Scientific document ingestion (LaTeX, JATS, math-heavy PDFs) will likely become a promoted use case as the output format support deepens.

OpenCode ships daily with GPT-6/Astra support, Claude 5.1 thinking blocks, and Azure enterprise auth

◆ Current state

OpenCode is shipping daily-to-weekly micro-releases with a tight focus on multi-provider reliability. GPT-6/Astra system prompt support, Claude 5.1 thinking block binding, and Azure Entra ID CLI sign-in all landed in the past two weeks. Each release also includes fixes for specific model providers (Bedrock DeepSeek, OpenAI compatibility, Cloudflare AI Gateway routing), reflecting the maintenance cost of maintaining a wide provider compatibility surface as that surface keeps expanding with new models.

◆ Where it's heading

The pattern of adding reasoning effort variants, thinking block management, and adaptive thinking summarization across providers shows OpenCode investing in first-class support for extended reasoning models—the category where Claude 5 and GPT-6 both live. Azure authentication improvements and Cloudflare AI Gateway routing fixes suggest the enterprise integration surface is expanding alongside model breadth. Anthropic's Claude 5.1 thinking block handling is a particularly active area.

◆ Prediction

Expect continued day-one support for major model releases from Anthropic, OpenAI, and AWS, with Claude 5.x and GPT-6 extended reasoning capabilities becoming better-differentiated features. Azure enterprise auth improvements are likely to continue through the current cycle.
