DeepSeek V4 Pro 0813 scores 53 on the Artificial Analysis Intelligence Index, 8 points above April's DeepSeek V4 Pro - but with a 3.6x price increase and only 1 point above DeepSeek V4 Flash 0731
@deepseek_ai has released DeepSeek V4 Pro 0813, its new flagship model, along with updated pricing. With the new pricing, it still sits on our Pareto frontier for Intelligence vs. Cost, but by a smaller margin than previous DeepSeek releases.
Under the new pricing, DeepSeek's first-party API will charge $1.32 / 1M input tokens and $3.96 / 1M output tokens - an increase of +264% on the blended price. Cached input tokens receive a ~97% discount (rather than the previous 99%): cache hits are priced at $0.044 / 1M tokens, 12x higher than previous cache-hit pricing. Off-peak pricing is discounted by 50%. This new pricing takes effect on August 16, 2026 - until then DeepSeek is offering V4 Pro 0813 at the same pricing as the earlier V4 Pro model.
DeepSeek published the model weights under the MIT license, making it the second most intelligent open weights model we have benchmarked; however, weights for Qwen3.8 2.4T A95B have recently been released and will be evaluated on the Intelligence Index soon. DeepSeek V4 Pro 0813 remains 7 points behind Kimi K3, the current open weights leader.
DeepSeek V4 Pro 0813 retains the previous version's architecture at 1.6T total parameters and 49B active parameters, with a context window of 1M tokens. Most of DeepSeek V4 Pro 0813's gains over the April version are in agentic capabilities. DeepSeek V4 Pro 0813 is more token efficient than its predecessor, generating ~30% fewer total output tokens across Artificial Analysis Intelligence Index.
Key results:
➤ DeepSeek V4 Pro 0813 is only 1 point ahead of DeepSeek V4 Flash 0731 on the Artificial Analysis Intelligence Index, and has ~3.8x the active parameters. The two models tie on Terminal-Bench 2.1 at 79%. For agentic and coding benchmarks the smaller model performed at around the same level.
➤ DeepSeek V4 Pro 0813 is more token efficient than DeepSeek V4 Pro, using 128M output tokens to run the Intelligence Index, ~30% fewer than the April version. This places DeepSeek V4 Pro 0813 on the open weights Pareto frontier for intelligence versus output tokens, with fewer tokens used than Kimi K3 (133M) and GLM-5.2 (141M). However, it lags behind many frontier models in its intelligence tier. GPT-5.6 Sol scores 61 on the Intelligence Index but only uses 70M tokens in total.
➤ Cost per Task increases significantly despite an improvement in token usage, driven by DeepSeek's price increase. At $0.25, DeepSeek V4 Pro 0813's Cost per Task is 5x that of DeepSeek V4 Pro ($0.05), but ~20% lower than GLM-5.2 ($0.32 Cost per Task). Despite the increase in price, DeepSeek V4 Pro 0813 still sits on the Intelligence vs. Cost per Task Pareto frontier, but barely - it is just one cent below Gemini 3.7 Flash (medium) on Cost per Task.
➤ DeepSeek V4 Pro 0813 makes significant improvements in real-world agentic knowledge work. On GDPval-AA v2 its Elo improved to 1590, +284 points from DeepSeek V4 Pro (1306), which implies an ~84% expected win rate against the April release. Its GDPval-AA v2 Elo is ahead of earlier-generation proprietary models like Claude Opus 4.7 and GPT-5.5, but it trails Kimi K3. DeepSeek V4 Pro 0813 works for longer on GDPval tasks than before, averaging 39 turns per GDPval-AA task compared to 23 for the April model.
➤ DeepSeek V4 Pro 0813 makes a 12 point improvement in AA-Omniscience, driven entirely by increases in accuracy. DeepSeek V4 Pro 0813 scores +1, up from -11 for DeepSeek V4 Pro. Its AA-Omniscience accuracy rises 6 points from 43% to 49%, while regressing slightly in hallucination rate from 94% to 95%. Compared to peer models, DeepSeek V4 Pro 0813 has a high attempt rate of ~99%, meaning it almost never declines to answer. By contrast, Kimi K3 attempts only 77% of questions and has a 53% hallucination rate.
