DeepSeek V4 Pro 0813 Max vs Beam 1.0: speed, latency and cost

Here is how DeepSeek V4 Pro 0813 (Max), built by DeepSeek, lines up against Beam 1.0 from Reflection. No hands-on testing went into this write-up; it summarises the recorded benchmark, price and speed data for both models. Throughput is the standout difference: 344 tokens per second for Beam 1.0 against 67 tokens per second for DeepSeek V4 Pro 0813 Max.

Throughput and time to first token

Measured output speed is 67 tokens per second for DeepSeek V4 Pro 0813 Max and 344 tokens per second for Beam 1.0. That makes Beam 1.0 roughly 5.1 times as fast at writing. Before any text appears, DeepSeek V4 Pro 0813 Max takes 1.7 seconds and Beam 1.0 0.70 seconds. Beam 1.0 gets to its first token 2.4 times as fast.

Put together, a 600-token answer would take about 11 seconds from DeepSeek V4 Pro 0813 Max and 2.4 seconds from Beam 1.0, counting the first-token wait.

Release timing

DeepSeek V4 Pro 0813 Max came first, on August 13, 2026; Beam 1.0 followed on October 16, 2026.

Token pricing and a sample bill

The list prices are $1.32 in and $3.96 out for DeepSeek V4 Pro 0813 Max, and $0.40 in and $1.20 out for Beam 1.0, per million tokens. That makes Beam 1.0's output 70% cheaper.

A reference job of 1 million input tokens and 200,000 output tokens costs $2.11 with DeepSeek V4 Pro 0813 Max and $0.64 with Beam 1.0, so Beam 1.0 saves $1.47. Scale it up to an agent that reads 50 million tokens and writes 5 million in a month and the bill is $85.80 for DeepSeek V4 Pro 0813 Max against $26.00 for Beam 1.0. On a 3:1 blend of input to output tokens, that works out to $1.98 versus $0.60 per million.
