OpenAI Launches GPT-6 Astra with Near-Perfect Benchmark Scores
OpenAI has released Astra, also known as GPT-6, calling it the company's most intelligent and aligned artificial intelligence model to date.

Key takeaways · 3
- 01
Astra achieved a 100% score on ExploitBench and saturated ARC-AGI-3 with 99.9% accuracy.
- 02
Access to the GPT-6 Pro chat mode is currently limited to Pro, Business, and Enterprise tiers.
- 03
ChatGPT Plus users can only access Astra through specific Work and Codex features.
Capabilities and Benchmarks
OpenAI claims its newly released Astra model, referred to as GPT-6, is the product of years of research and heavy computational investment. [3] The system achieved a 98% score on the FrontierMath Tier 4 benchmark. [3] Additionally, the model saturated the ARC-AGI 3 benchmark with a 99.9% accuracy rate and scored 100% on ExploitBench. [3] Despite these high scores, independent experts noted that the launch messaging serves marketing goals alongside real progress. [3]
Access and Availability
The Astra model currently powers the GPT-6 Pro offering in normal chat for users on the Pro, Business, and Enterprise tiers. [1] In contrast, standard Plus users currently only access Astra through the Work and Codex features. [1] A community member noted that while one announcement suggested Astra would be available to all Plus, Pro, Business, and Enterprise users, current documentation shows Plus users only receive access through Work and Codex rather than the standard Chat interface.

What it means
OpenAI is pushing the limits of benchmark testing with Astra, specifically targeting advanced reasoning and exploit discovery. By limiting full chat access to premium tiers, the company is likely prioritizing high-revenue enterprise customers for its most computationally expensive models. The selective availability implies a tiered rollout strategy for bleeding-edge capabilities, diverging from the broader access models seen in earlier GPT-4 iterations. What the sources don't address: Whether OpenAI intends to eventually bring the fully powered GPT-6 Pro chat experience to standard Plus subscribers.
The release of GPT-6 Astra establishes a new high-water mark for AI performance on advanced logic and security benchmarks. However, tiered access highlights the growing divide between enterprise and consumer AI availability.
