## Summary

A leaderboard released on Hacker News shows that the multimodal model GPT-6 Astra completed a simulated driving course with 100 % progress in 5 minutes 22 seconds. The test allowed up to three attempts in a single continuous chat, recording distance, speed, finish time and token usage for each run. In the same benchmark, Anthropic’s Claude Fable 5.1 reached 45 % of the course, while Grok 4.6 managed 11 % and OpenAI’s GPT‑5.6 achieved only 6 %.

The table also lists token counts and list‑price costs for each attempt, though exact numbers are not shown. GPT‑6 Astra’s performance suggests it can maintain lane position within a 4‑meter corridor while navigating the track, a step toward autonomous‑driving capabilities for large language models. The results are presented without independent verification, and the source does not name the organization behind GPT‑6 Astra.

## Key points

- GPT-6 Astra completed the driving course with 100% progress in 5:22, outperforming other models.
- Claude Fable 5.1 reached 45%, Grok 4.6 reached 11%, GPT-5.6 reached 6% on the same test.
- Leaderboard records distance, speed, finish time, token usage and cost for up to three attempts per model.

## Why it matters

Demonstrates that large language models can control physical agents, moving AI closer to real‑world autonomous‑driving applications.
