Why DeepSeek V4 Flash 0731 on Together AI

We build for production workloads — not just demos

Leading price performance

Full-stack optimizations deliver higher throughput and lower latency than the leading open source implementations on identical hardware.

Run it your way

Serverless scales to your traffic with per token pricing. Dedicated gives you isolated GPUs tuned to your workload.

Backed by research
that ships

Inference performance is driven by continuous optimization across kernels, scheduling, and runtime systems.

About

DeepSeek V4 Flash 0731 is the official release of DeepSeek's efficiency-focused V4 Flash model, superseding the April preview with substantially stronger agentic capability. It is a Mixture-of-Experts model with 284B total parameters and 13B active per token, supporting a 1M-token context window on a hybrid attention design built to keep ultra-long-context inference cheap, and it ships with a speculative decoding module attached for faster generation. Reasoning effort is adjustable per request across low, high, and max levels, letting the same deployment serve quick responses and deep deliberation. DeepSeek reports the release outperforms the much larger V4 Pro preview on its published agentic benchmark set despite far fewer activated parameters. Released under the MIT license. Available on Together AI.

"Low latency is especially important for voice because there’s a much higher UX bar. Together helped us push latency down by optimizing our models with techniques like speculative decoding, and they’ve been a reliable production partner — proactive about risks and fast when issues come up."

"Together has helped us deploy VyUI, our state-of-the-art computer AI model. We had multiple in-depth meetings where we brainstormed how we could satisfy our model's custom technical requirements while still leveraging Together's infrastructure for efficient, load-balanced inference."
