# First outputs from GPT-6 "Astra" model from OpenAI > Source: > Published: 2026-08-29 14:47:57+00:00 OpenAI appears to be moving Astra closer to release, with reports pointing to expanded internal testing and a new checkpoint identified as “mozaik-alpha-fdm.” The latest surfaced outputs were reportedly generated zero-shot with Max effort, where Astra spends substantially longer reasoning than GPT-5.6 Sol. The examples point to a strong focus on coding and visual software creation. Astra reportedly produced a GTA 2-style game in one attempt, alongside detailed websites, 3D objects, and voxel environments. The main difference visible in these samples is attention to small implementation details and the amount of complete functionality produced from a single prompt. Developers, designers, and founders building prototypes could be among the main beneficiaries if this performance carries over to the released model. Astra could arrive through [ChatGPT](https://www.testingcatalog.com/tag/chatgpt/), Codex or both, especially given OpenAI's focus on agentic coding and long-running work. OpenAI has not announced a release date or confirmed that “mozaik-alpha-fdm” is an official codename. Separate reports have suggested a launch within weeks, while the newly expanded testing provides another indication that preparations are progressing. One major variable remains timing: safety approval. OpenAI has officially acknowledged Astra as an upcoming model and said its internal evaluations showed major advances in agentic coding and cybersecurity, potentially reaching its Critical cyber capability threshold. Some Astra workloads were subsequently paused while stricter safeguards were introduced. OpenAI has also confirmed that relevant government agencies and selected AI safety organizations will participate in testing. This makes government evaluation part of the actual deployment process rather than simply another rumor. It also means a technically ready Astra may still remain gated until OpenAI is satisfied with its monitoring, alignment, and containment systems. Meanwhile, several people with histories of early access to frontier models have hinted that Astra represents a much larger capability jump than recent [OpenAI](https://www.testingcatalog.com/tag/openai/) releases. GPT-6 remains a plausible public name, but OpenAI has given no indication that it has chosen this branding. Source: [zAI Discord](https://discord.gg/3Km9qnH6D?ref=testingcatalog.com)
