Elon Musk's Grok V9-Medium completes supplementary training, introducing Cursor data to target complex programming scenarios

Abstract generation in progress

According to Beating Monitoring, Elon Musk announced that the 1.5 trillion parameter basic model Grok V9-Medium under xAI has completed training and is expected to be released to the public within 2 to 3 weeks. Currently, the model has entered the supervised fine-tuning stage and will begin reinforcement learning training in a few days. The R&D team has incorporated a large amount of Cursor's code data during supplementary training and will continue to feed more samples in the future.

Compared to the v8-small model, which currently supports all production traffic for Grok, the 1.5 trillion parameter Grok V9-Medium will achieve significant upgrades in handling complex programming tasks. Previously, Elon Musk publicly admitted that the v8-small (the external testing version Grok 4.2), with only 0.5 trillion parameters, had serious flaws in data quality, comprehensiveness, and proportion. The trained Grok V9-Medium not only expands its parameter scale to three times that of its predecessor but also has been specifically optimized for Blackwell architecture GPUs.

Parameter scale doubles again and again, the scaling law is still in effect

Let's run a few more weeks in the RL phase; don't rush to release a semi-finished product.

Just waiting for the price, don't be as expensive as some company that charges an outrageous amount.

v8-small has held up until now, and the xAI infrastructure team’s resilience under pressure proves it.

Supervised fine-tuning still requires RL; the training process is quite complete.
