A "DeepSeek V4.1" release appears likely. Community reports indicate the model's knowledge cutoff has been updated to June 2026, suggesting a new version is in testing. This is further supported by a planned API deprecation on July 24, which often precedes a new model launch.
2026-06-24 · Jul 2026 – Sep 2026 · 35%
Multiple leaks indicating performance improvements and an updated knowledge cutoff for the current model suggest an incremental update is being tested. This, combined with a legacy API deprecation scheduled for July 24, increases the likelihood of a near-term release.
2026-06-24 · Jul 20 – Aug 31, 2026 · 35%
Reports of sudden performance improvements in DeepSeek V4 Flash and rumors of a 'V4.1' update with a June 2026 knowledge cutoff suggest active development of the next model. While a prominent leaker noted that missing the mid-June window might push back the timeline, the upcoming deprecation of legacy API names on July 24, 2026, remains a strong indicator of an impending transition, leading us to forecast a release window between late July and mid-September 2026.
2026-06-21 · Jul 20 – Aug 31, 2026 · 35%
With no new external signals detected since the launch of DeepSeek V4 Pro in late April 2026, the prediction for DeepSeek V5 remains anchored to the historical cadence. We maintain the current forecast window of late July to August 2026, representing a typical progression from the V4 preview phase, though confidence remains moderate at 35% due to the lack of recent official hints.
2026-06-14 · Aug 2026 – Nov 2026 · 20%
The official, permanent price reduction for the DeepSeek V4 Pro API is a strong market signal that often precedes the release of a successor model. While geopolitical and regulatory pressure from the U.S. introduces some uncertainty, this economic signal points towards an earlier release than the baseline forecast.
2026-06-14 · Aug 2026 – Nov 2026 · 20%
With no new concrete signals regarding DeepSeek's next model, the forecast remains at the statistical baseline derived from historical release cadence. The prediction window and confidence level are therefore unchanged.
