첫 번째 항목은 항상 핀의 출처입니다. 전체 신뢰도는 각 자료가 위의 시작·종료 시각을 얼마나 확실히 뒷받침하는지에 대한 가중 평균이며, 자료는 최신 자료보다 180일 오래될 때마다 가중치가 절반이 됩니다.
Kling's 30 September blog said the full model was "coming in October 2026" with early access from 28 September (Kling 4.0 Flash for Ultra Yearly subscribers); ScriptByAI[5] marks it 'Full Available' on 15 October and a review cites Kling's 15 October post on X. The Decoder[2] covered it on 19 October and the API rolled out from about 21 October, so 15 October is the full-model date.
19 October 2026: 30-second clips, ten keyframes, 8,000-token prompts, stereo audio and Flash (720p, 20 s); in a comparison video 4.0 'holds its own but doesn't pull ahead' of Wan 3.0 and Seedance 2.5.[1]
30 September 2026: the 4K and 10-bit HDR output is 'coming soon'; keyframes are reference images, not animation keyframes, and filmmakers say consistency across cuts still needs work.[1]
Reseller timeline: Flash early access 28 September, full model and API in October; its endpoints give 3-30 second clips at 720p or 1080p with stereo audio and up to 10 images, 5 videos and 3 audios as references.[1]
Dates Flash early access to 28 September, the full-model announcement to 30 September and full availability to 15 October 2026.[1]

Kling 4.0 holds its own but doesn't pull ahead, especially when it comes to logical shot sequencing, physics, and natural-sounding dialogue.
At complex motion or character-heavy transitions, the model can produce morphing artifacts, inconsistent scale, or hands that change between reference frames.
Most evidence so far is vendor-chosen or early-access.
