Tern
What ChatGPT, Claude, Gemini & Grok actually say · August 2026
The verdict
Tern appears in 2 AI-ranked categories — best position #5 for sbom generators for container images.
Delivers meticulous layer-by-layer OCI/Docker image inspection to map software provenance back to exact image layers for precise license and software compliance auditing.
Grok Deepest container-native layer-by-layer analysis with superior license attribution and OS-package metadata (especially Debian/Ubuntu/RHEL derivatives); still actively maintained in 2026 and purpose-built for image and Dockerfile inspection
Claude Purpose-built for container images with a distinctive layer-by-layer analysis that attributes packages to the Dockerfile instructions that introduced them, giving unusually good provenance and license insight for images built from Dockerfiles; emits SPDX and CycloneDX.
Where Tern falls short, per the models
- Claude Slower, heavier (often needs to run/inspect layers), narrower maintenance and ecosystem breadth than Syft/Trivy, and weaker on non-Dockerfile or scratch/distroless images — a specialist tool, not a general default.
- Gemini Execution time is significantly slower on complex, multi-stage images, making it poorly suited for fast CI/CD build gates.
- Grok Dramatically slower (often ~10×) than peers and narrower language-ecosystem coverage, making it impractical for high-frequency pipelines
