* ExploitBench – 100%



OpenAI also claims the model runs computer-use tasks nearly twice as fast as its predecessor. Worth noting: a good part of that speed gain comes from improvements to the surrounding harness rather than the model itself — the same optimizations boosted GPT-5.6 Sol's speed by roughly 60%, too.

## What changes for developers using Codex

For anyone running long Codex sessions, this is the update that matters most. Until now, once a context window filled up, models fell back on compaction — condensing earlier work into a summary, which often meant losing the "why" behind a failed fix or how a given component actually behaves.

Astra takes a different route. It maintains ongoing notes that carry across context windows instead of collapsing everything into a single summary. On top of that, earlier context windows remain searchable, so the model can pull specific requirements or test results from past messages and tool outputs even when its own notes didn't capture them. The feature is opt-in right now, but OpenAI expects it to become the default within a few weeks.

## Beyond code: computer use and document generation

Astra combines computer-use capability — including background operation — with training geared toward professional workflows: handling multi-step tasks and producing finished documents, spreadsheets, and presentations. OpenAI is calling it their strongest model yet for software engineering. Through ChatGPT's Sites feature, it can also build, host, and share complete websites, web apps, and games.

## Access and pricing

The model is available via the API under the ID `gpt-6-astra`, with a 1M-token context window. Pricing is set at $10 per million input tokens and $50 per million output tokens, with cached input priced at $1, batch processing available at half price, and Fast mode running at twice the standard rate. For ChatGPT users, usage draws from existing subscription allowances, with the option to purchase additional credits if needed.

## On the safety front

OpenAI confirmed that Astra is the first of its models to hit the company's internal "Critical" cybersecurity threshold under its Preparedness Framework. As a result, the model's cyber-related capabilities are restricted to the Daybreak program rather than being rolled out broadly from day one.
