DeepSeek V4 Release Timing and Huawei Delay Claims

Claim checked

“From an interview with a mysterious source: DeepSeek V4 is indeed scheduled to be released next week. The delayed release of DeepSeek V4 has nothing to do with Huawei Ascend; it is purely because the results were not satisfactory.”

Verdict

Mixed

While reports from mid-April 2026 support a potential release of DeepSeek V4 in late April, the claim that delays are unrelated to Huawei Ascend hardware is contradicted by multiple industry reports.

  • Release Timing: Sources indicate a target window of late April 2026, which aligns with the "next week" claim made on April 19.
  • Huawei Involvement: Major reporting from the Financial Times and The Decoder explicitly links DeepSeek's development delays to technical hurdles encountered while training models on Huawei's Ascend chips.

7 reviewed sources behind this verdict.

Reasoning

The claim accurately reflects current rumors regarding the release window but provides a narrative about the cause of delays that conflicts with established reporting.

Evidence from Gizchina and Reuters confirms that DeepSeek V4 has faced multiple delays but is currently aimed for a late April 2026 launch. However, the assertion that these delays have "nothing to do with Huawei Ascend" is refuted by reports detailing how DeepSeek's shift from Nvidia to domestic Chinese silicon (Huawei) resulted in persistent technical issues and failed training runs. While "unsatisfactory results" may be the outcome, the primary cause cited by industry sources is the hardware transition.

Source quality: The evidence includes reports from reputable outlets like the Financial Times and The Decoder, as well as tech-specific coverage from Gizchina that cites Reuters and The Information.

Key checks

  • DeepSeek V4 Release Date: Reports from April 11, 2026, indicate that DeepSeek V4 is expected to launch in late April 2026. Given the current date of April 19, a release "next week" is consistent with these industry expectations.

  • Connection to Huawei Ascend Chips: Contrary to the claim, multiple sources report that DeepSeek V4 is the first frontier-class model built specifically around Huawei's Ascend infrastructure. Delays were specifically attributed to technical issues and "growing pains" associated with these Chinese chips.

  • Reason for Delays: While the claim states delays were purely due to unsatisfactory results, reporting indicates the team faced persistent technical issues with Ascend chips that prevented successful training runs, forcing a temporary fallback to Nvidia hardware for compute-heavy tasks.
