**The AI index exceeded 65 while DeepSeek confirmed it will not release an R3 model.**

On Thursday 1 October, NVIDIA emerged as the Largest company at the end of September. The Artificial Analysis Intelligence Index recorded a score of 65 or higher on 30 September. DeepSeek announced that its upcoming reasoning model would not be named R3. These developments highlighted AI's expanding role in corporate performance metrics.

The ranking considered companies' positions as of the end of September. NVIDIA secured the top spot, surpassing peers such as Apple and Alphabet. The result was confirmed on Thursday 1 October.

The Artificial Analysis Intelligence Index measures AI sector momentum. On 30 September, the index rose to at least 65.

DeepSeek evaluated names for its next reasoning model. The company decided against using the designation R3. The decision was logged on Wednesday 30 September.

## Analysis

Its lead suggests that demand for advanced graphics and compute capabilities continues to drive corporate valuations, potentially shaping investment flows toward similar technology providers.

Such a rise may encourage further capital allocation to AI research and development, while also prompting regulators to examine the implications of increasingly powerful models on data privacy and competition.

DeepSeek's choice not to launch a model named R3 indicates a deviation from an expected naming sequence, which could reflect strategic revisions or technical challenges. Without additional details, the impact on DeepSeek's product timeline remains uncertain, but the decision may affect its positioning relative to other AI developers.
