Anthropic Replaces Git With In-House Scion, Daily Merges Top 30,000

The notable point is not the tool but the operating cadence: a seven-person team reworking the merge bottleneck produced a twelvefold jump in daily landed changes, which suggests version control throughput, not model quality, was gating iteration speed. That matters most for large monorepo operators whose CI and code-fetch latency caps how fast research and product teams can ship. Anthropic's explicit framing that Scion is not a general git replacement keeps this an internal infrastructure story rather than a product launch, so the open question is whether the approach stays bespoke to Anthropic's scale or becomes a template others copy.
