DeepSeek-V4 Pro now available on Together AI

What's New DeepSeek V4 Pro on Together AI: DeepSeek V4 Pro is now available on Together AI with a 512K-token context window for long-context reasoning workloads. Large-scale MoE architecture: DeepSeek V4 Pro uses a 1.6T-parameter Mixture-of-Experts architecture with 49B activated parameters. Controllable reasoning modes: Non-Think, Think High, and Think Max let teams choose between fast responses, deeper reasoning, and maximum reasoning effort. ‍ Transparent serverless pricing: DeepSeek V4 Pro is available at \$2.10 per 1M input tokens, \$0.20 per 1M cached input tokens, and \$4.40 per 1M output tokens. Long-context reasoning changes what teams can ask a model to do. Entire repositories, large document sets, long agent traces, and tool outputs can fit into the model’s working context instead of being compressed into brittle summaries. But the models that can use that much context are also the hardest to serve: a 1.6T-parameter MoE with million-token context is not something most teams want to deploy, tune, and operate themselves. …
