DeepSeek V4 Pro 0813
Flagship GA
App, Web and API now point deepseek-v4-pro at the 0813 build. DeepSeek says production-agent gains are the headline — not another lab-only table.
Highlights
HF model size
MIT weights: deepseek-ai/DeepSeek-V4-Pro-0813. Preview structure + DSpark.
Miss / output now
Cache hit $0.003625. Peak/off-peak from 2026-08-16 16:00 UTC. Concurrency 500.
Terminal Bench 2.1
Official Minimal+max. DeepSWE 62.7 (Preview Pro was 12.8). HLE w/tools 60.0.
Context / max out
low / high / max effort. Responses API + Codex one-click script.
What 0813 changes
0813 supersedes V4-Pro Preview. Reuters covered the formal release as DeepSeek stepping up hiring, compute and fundraising. Simon Willison noted there was no pretty announcement page — this guide is the human changelog.
What people are arguing
HF’s own table puts 0813 next to Fable 5 (w/ fallback), Kimi K3 and Opus 4.8. TB2.1 is essentially tied with Fable (87.9 vs 88.0); DeepSWE still trails (62.7 vs 70.0). Price remains an order of magnitude lower.
Timeline
V4-Pro Preview in API.
0813 GA on App, Web, API. Reuters same day.
Peak/off-peak. Peak out $3.96, off-peak $1.98.
Confirmed vs caution
Confirmed
Official bench table on HF; MIT repo; same model name; three effort levels; Codex Responses path.
Caution
Plenty of "V4 Pro 45 vs Sol 57" charts are still circulating; those describe the pre-0813 Preview build. Artificial Analysis scores the 0813 release at 53.
Pick Flash or Pro
Stay on Flash 0731
Default lane. 2500 concurrency. Cheaper. Already strong on TB2.1 82.7.
Escalate to 0813
Harder production agents, HLE-with-tools, when Flash stalls. 500 concurrency.
How to call it

0813 FAQ
Do I change the model name?
No. Keep deepseek-v4-pro. 0813 is the new default behind the name.
Open weights?
Yes, MIT on Hugging Face.
Better than Fable 5?
Not overall. TB2.1 is a tie; DeepSWE/HLE still favor Fable (w/ fallback). Pro wins on price and self-host.
Better than GPT-5.6 Sol?
They target different jobs. GPT-5.6 Sol is the closed reasoning flagship at 61 on the Artificial Analysis Intelligence Index; V4 Pro 0813 scores 53 there and wins on price and open weights. The "Pro 45" figure still circulating describes the pre-0813 Preview build.
Flash 0731 or Pro 0813?
Flash first. Pro when Flash fails the hard agent loop.
When do prices change?
2026-08-16 16:00 UTC, peak hours 01:00–04:00 and 06:00–10:00 UTC.

Route hard jobs to a cheaper flagship
Keep Claude / GPT where they still win; use 0813 when open weights and price matter.
