About this model

DeepSeek-V4-Flash-0731 is the official release of DeepSeek-V4-Flash, published on 31 July 2026 under the MIT license. It is a Mixture-of-Experts model with 284B total parameters, 13B of them active per token, a one-million-token context window and text-only input. On Scaleway, which serves it here, the window is limited to 256k tokens during the preview stage. Reasoning effort can be set to low, high or max. DeepSeek says this release brings substantially enhanced agentic capabilities over the preview, and reports that it outperforms the DeepSeek-V4-Pro preview, also in this catalogue, on the agent and coding benchmarks it lists, for example 82.7 on Terminal Bench 2.1. That makes it a practical fit for coding agents, tool-driven workflows and long-document analysis.

Frontière AI retains neither prompts nor completions from API calls; processing is structured to fit a short DPA (Art. 28 GDPR). DPA and subprocessor documentation available on request.

What its label means

This model is run by a French provider (OVHcloud or Scaleway), in data centres in France. It is not a US company, so the CLOUD Act does not reach it the way it reaches a US provider, and under GDPR a foreign court order is only enforceable in the EU through an international agreement (Article 48). That is the SecNumCloud principle — who controls the operator matters more than where the servers sit — applied as a label, not a qualification: this service is not SecNumCloud-qualified. Our gateway runs in Vercel's Paris region (a US company): your prompts pass through it without being stored.

FAQ

Is DeepSeek V4 Flash 0731 GDPR-compliant on Frontière AI?

It is the setup a GDPR assessment looks for: DeepSeek V4 Flash 0731 is served by Scaleway, a French company, in data centres in France — not a US provider, so outside the CLOUD Act's direct reach. Your prompts transit through our gateway, hosted by Vercel in Paris (a US company), without being stored: Frontière AI keeps only the token counts billing requires. Compliance also depends on your use and your data processing agreement.

How much does DeepSeek V4 Flash 0731 cost?

€0.0672 per 100,000 input tokens and €0.1344 per 100,000 output tokens — margin and VAT included, that is the amount debited from your prepaid balance. No subscription: you top up from €10; calls are refused once the balance reaches zero, and a call already running can take it slightly below — deducted from your next top-up.

How do I call DeepSeek V4 Flash 0731 from my code?

Under which licence is DeepSeek V4 Flash 0731 released?
