DeepSeek V4 Specs and Pricing Leak Spark Debate
Leaked DeepSeek API docs and online rumors have revealed core specs and suspected pricing for the next-generation V4 series, drawing significant community attention. Model capabilities are largely clear, but pricing reports conflict sharply, and all information awaits official confirmation.
Confirmed
- Multiple media and bloggers report API doc pages showing DeepSeek plans to release V4 series models: deepseek-v4-flash and deepseek-v4-pro.
- Both models support up to 1M context length and 384K max output.
- User @赛博禅心 notes that model name deepseek-v4-pro and endpoint DeepSeek-V4-Pro appear accessible via API, though no official announcement has been made.
Unconfirmed
- Pricing rumors diverge: @teortaxesTex relays leaked prices of $2.40/M input, $4.80/M output, $0.20/M cache hit (about 5.5x current prices).
- @haider1 posts benchmark and pricing data suggesting disruptive low prices: $0.435/M input, $0.87/M output, $0.07/M cache input (exact figures per original post).
Why it matters
- If the 1M context spec is real, DeepSeek V4 would rank among the top in long-context capability. The final pricing, whether a sharp increase or continued low cost, will directly impact the API price war in the LLM industry.
