Archon is a workflow orchestration engine for AI coding agents that lets developers define development phases — planning, implementation, review, PR creation — as YAML configuration files. Agents follow these deterministic workflows instead of improvising, making their behavior predictable and auditable. The engine ships with 17 pre-built workflows covering common software tasks and runs anywhere: CLI, web dashboard, Slack, Telegram, or GitHub webhooks. Teams can compose custom workflows from atomic steps, set retry policies, and inspect execution traces. Archon addresses the core reliability problem with coding agents: they work brilliantly in demos but drift unpredictably in production. By externalizing workflow logic from the model, it does for agent orchestration what GitHub Actions did for CI/CD — brings structure to a previously ad-hoc process.

SmolDocling is a 256-million-parameter vision-language model from IBM Granite that converts documents — PDFs, scanned papers, tables, charts, forms — into clean, structured text with remarkable accuracy for its size. It introduces a new markup format called DocTags that captures not just text but document structure, reading order, and element types (headings, captions, tables, code blocks) in a way that downstream models and parsers can reliably consume. The "smol" in the name is intentional: at 256M parameters, SmolDocling runs fast enough to be deployed in production pipelines where larger VLMs would be prohibitively slow or expensive. Despite its compact size, IBM reports it achieves state-of-the-art performance across multiple document type benchmarks — outperforming much larger models on structured document parsing tasks. The key innovation is the DocTags format, which gives the model a precise vocabulary for describing document elements rather than trying to reconstruct structure from freeform text output. Built on top of the docling project (58.7k GitHub stars), SmolDocling is open source under Apache 2.0 and available on HuggingFace. The technical report is on arXiv (2503.11576). For teams building RAG pipelines, document intelligence tools, or any system that needs to ingest unstructured documents at scale, this is a practical, deployable solution.
Reviewer scorecard
“Finally, a way to run coding agents without crossing your fingers. The YAML workflow approach is immediately familiar for anyone who's written GitHub Actions — you get predictability, retries, and audit logs instead of hoping the agent remembers what you asked. The 17 pre-built workflows cover 80% of real sprint tasks.”
“256M params that actually handle real-world PDFs including tables, charts, and mixed layouts — this goes straight into my RAG preprocessing pipeline. The DocTags format is smart: giving the model a precise document vocabulary instead of asking it to improvise structure from scratch.”
“Adding a YAML config layer on top of an LLM doesn't solve the fundamental problem — the model still decides what to write inside each phase. All you've done is move the unpredictability from 'what will it do' to 'what will it produce in step 3.' Most teams need better evals, not better scaffolding.”
“IBM's benchmark numbers for SmolDocling were measured on datasets curated by the same team. Real-world document parsing — especially for scanned documents with skew, noise, or unusual layouts — is where small VLMs consistently fall apart. Test it on your actual documents before committing it to production.”
“Workflow-as-code for agents is exactly where enterprise software teams will converge. When you need to audit why an agent changed a payment system module, 'here's the YAML it followed and here's its execution trace' is a legally defensible answer. This kind of infrastructure is table stakes for AI in regulated industries.”
“Efficient document parsing is critical infrastructure for the AI economy — most enterprise knowledge lives in PDFs and Word docs, not clean databases. A 256M model that can do this well enough to be deployed in high-throughput pipelines removes a major bottleneck from enterprise AI adoption.”
“Even for creative and design workflows, the phase-based approach is useful — 'research phase, concept phase, production phase' maps perfectly to how design sprints actually work. Running it through Slack or Telegram triggers means the whole team can kick off AI workflows without touching a terminal.”
“Finally being able to reliably extract content from design-heavy PDFs — charts, callouts, multi-column layouts — without everything turning into garbage text is genuinely useful for content repurposing workflows. DocTags also makes it easier to preserve the editorial structure of source documents.”
