GPT-6 Astra in Practice: Tests, Use Cases, and Feedback

Researchers say Astra solved 49 of 50 unpublished theoretical physics problems at 98% for under $3 per problem, and that answers first marked wrong turned out to expose errors in human calculations.

The author asked Codex to design the fastest, lowest-friction import flow, so footage can be imported over a cable or trickled in over Wi-Fi in the background, with firmware info also viewable.

The author argues OpenAI is replaying Anthropic's script: first winning developers with generous limits, then countering with GPT-6.1 Astra once Fable 5.5 ships.

The author built Garage to Grid, a game about fixing cars and growing a garage, live with Crayon Pro and GPT-6 Astra, and shared a playable link.

Ultrafast versions of GPT-6 Astra and SOL 6.1 are now available in Perplexity Computer for Max subscribers, generating tokens faster to finish long tasks sooner.

The new Tesseract tool supports ACES and LUTs, enables shot-by-shot grading and per-color shifts, and keeps layers editable in an agent or in Premiere and After Effects.

Gemini 4 Argon, Claude Sonnet 5.5, GPT-6 Astra and Opus 5.5 were given the same prompt, "Build a night train," and the results are compared side by side.

One prompt has Opus 5.5, Gemini 4, GPT-6 Astra and Kimi K3 each build a top-down traffic simulation, and the author compares cost and output quality, finding Astra the priciest but cleanest on lanes and traffic flow.

Design Creativity Bench tests 16 models on 80 UI tasks, with GPT-6 Astra scoring 65.5 against a human designer reference of 92.3.

The third-party agent tool HermesAgent gets a major overhaul, adding support for GPT-6 Astra/Sol/Luna and sharply reducing the token cost of tool definitions.

A developer shares RHAE results from months of running Codex and Claude Code on the public ARC-AGI-3 demo, saying Astra blew past the benchmark and killed his interest.

The author announces an October 15 YouTube livestream comparing Gemini 4 Argon and GPT-6 Astra on detection, segmentation, transcription, data extraction, efficiency and cost.
