Model intelligence
Historical DeepSeek R1 reasoning model. The R1-0528 snapshot was announced on 2025-05-28 and the related R1-0520 build referenced in Sprint 8B's preferred-target list belongs to the same family. The current DeepSeek chat-completions endpoint accepts only `deepseek-v4-flash` and `deepseek-v4-pro` as model values, so R1 is recorded here as a historical reference rather than a currently callable model.

Each row reflects the actual state on the record — no checkmark is asserted without isVerified() returning true.

Data gaps
These fields are intentionally null until verified against a primary source. They are not estimated.
Context window
Not yet sourced from official documentation for this model.
Max output tokens
Provider docs do not publish a max-output number separately from the context window for this model, or the field has not yet been retrieved.
Modality channels
Provider docs describe the model without enumerating which input/output channels are supported, or the field has not yet been retrieved.
Knowledge cutoff
No reliable cutoff date published in provider docs for this model.
Pricing
No pricing rows verified yet. Provider pricing pages may render with JavaScript only, or may not publish per-model rates at a stable URL.
Benchmark scores
No third-party benchmark scores have been verified for any model on this site — see the benchmark-limitations guide for why.
Infrastructure (regions / latency / uptime)
Infrastructure fields are intentionally null until a durable measurement source is wired. See the inference-infrastructure guide.
How a value moves from this list to a verified row — see source verification methodology.
API pricing
Per-unit rates published by DeepSeek for its own first-party API. Each row is a source-backed reference, not a live quote. Where DeepSeek does not run a paid first-party API for this model, the table renders the unverified-data label and any hosted-provider rates appear below.
Pricing is volatile and may change after retrieval. Treat prices as source-backed references, not live quotes.
Data not yet verified.Capability
Benchmark scores are only published once verified against a primary source. WebmasterID Models does not republish provider-reported scores without an independent reference.

Entity graph
Historical release note for DeepSeek-R1-0528 (May 28, 2025). Used to anchor the historical deepseek-r1 catalogue entry — R1 family is not in the current API model parameter set.
DeepSeek chat completion API reference — endpoint, model parameter values (deepseek-v4-flash, deepseek-v4-pro), minimal request body.
Next review for this entity targets re-checking pricing against official provider documentation and confirming lifecycle state. Cadence per field type lives in /docs.
