| **Training.** Grok 4.6 went through a longer supplemental training run than Grok 4.5, using curated model-generated data for reasoning and advanced technical concepts, high-quality engineering data, and an improved optimizer and training recipe. SpaceXAI then used Grok 4.5 itself to regenerate the supervised fine-tuning trajectories across reasoning efforts, agent harnesses, and domains including STEM, software engineering, and knowledge work, filtering out problematic traces with model-based checks. Reinforcement learning ran on agentic tasks including general coding, knowledge work, kernel optimization, web development, and computer-aided design. | ||

| **Longer trajectories.** SpaceXAI says the model stays with complex tasks across many steps, and that on longer runs it started to see more self-testing and verification, with the model checking its own work before moving on. That behavior is the difference between an agent you can leave running and one you have to babysit. |

Don't think configurable efforts is the grounds to add it in table, it's better to just remove this one

I don't think the table is serving much purpose here, as we already cover Artificial analysis in the next heading, and primary focus is not really the major deal

Opus 4.8 and Gemini 3.1 Pro are not a good comparison, these are outdated models, let's use Fable 5 and Opus 5 instead.

| The output side is where the gap shows. Agents spend most of their tokens writing: plans, tool arguments, diffs, test summaries, review notes. Moving from $25 or $30 per million output tokens to $6 changes which long tasks are worth automating at all, which is the same argument that made [Grok 4.5 interesting on cost](/blog/post/grok-45-coding-model). | ||

I'd suggest removing this section. Table already contains what we already had above. And Grok is probably the fastest model out of OpenAI, Anthropic and xAI.
