Intelligent video playback

A computing system, comprising:

• one or more processors;
• and
• one or more memory storing program instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• determining that content items are to be provided to a first client device;
• determining, based at least in part on the determination that content items are to be provided to the first client device and a first plurality of embedding vectors associated with a corpus of content items, a first plurality of responsive content items from the corpus of content items;
• determining, based at least in part on a second plurality of embedding vectors associated with the first plurality of responsive content items, a first relevance score associated with each of the first plurality of responsive content items;
• providing, to the first client device, the first plurality of responsive content items;
• obtaining, from the first client device, a plurality of playability information associated with the first plurality of responsive content items;
• determining that content items are to be provided to at least one of the first client device or a second client device;
• determining, based at least in part on the determination that content items are to be provided to at least one of the first client device or the second client device, a third plurality of embedding vectors associated with the corpus of content items, and the plurality of playability information, a second plurality of responsive content items from the corpus of content items;
• determining, based at least in part on a fourth plurality of embedding vectors associated with the second plurality of responsive content items and the plurality of playability information, a second relevance score associated with each of the second plurality of responsive content items;
• and
• providing the second plurality of responsive content items in accordance with the second relevance score.

One or more non-transitory computer readable storage media having instructions that, when executed by one or more computers, cause the one or more computers to perform operations comprising:

• determining that content items are to be provided to a first client device;
• determining, based at least in part on the determination that content items are to be provided to the first client device and a first plurality of embedding vectors associated with a corpus of content items, a first plurality of responsive content items from the corpus of content items;
• determining, based at least in part on a second plurality of embedding vectors associated with the first plurality of responsive content items, a first relevance score associated with each of the first plurality of responsive content items;
• providing, to the first client device, the first plurality of responsive content items;
• obtaining, from the first client device, a plurality of playability information associated with the first plurality of responsive content items;
• determining that content items are to be provided to at least one of the first client device or a second client device;
• determining, based at least in part on the determination that content items are to be provided to at least one of the first client device or the second client device, a third plurality of embedding vectors associated with the corpus of content items, and the plurality of playability information, a second plurality of responsive content items from the corpus of content items;
• determining, based at least in part on a fourth plurality of embedding vectors associated with the second plurality of responsive content items and the plurality of playability information, a second relevance score associated with each of the second plurality of responsive content items;
• and
• providing the second plurality of responsive content items in accordance with the second relevance score.
