Partial outage now. Partial System Degradation: Delayed Costs Data in the Compliance API
From the vendor's own status page. Uptime is the share of the window not covered by a major or critical incident (582 min down, 4871 min degraded); it covers the whole service, not this version alone.
Estimate from the version's published specs, benchmarks and reviews, 0-5; scores are only comparable within one criteria year. Scored as launched (GPT-5.3-Codex, 5 Feb 2026): shipped in Codex surfaces first, API followed later in Feb (Kilo post of 25 Feb), so no launch list price (current page $1.75/$14) and price is null. 400k context, text+image input (current OpenAI model page). Maker figures: Terminal-Bench 2.0 77.3% (Opus 4.6 65.4%), SWE-Bench Pro 56.8%, OSWorld-Verified 64.7%; AA's later Terminal-Bench Hard reading was 53% (via AA's GPT-5.4 post). None is Terminal-Bench 4.0, so coding is null. No launch-time AA Intelligence Index entry opened (AA marks it Estimated): reasoning and speed null.[2]
Codex, on the other hand, actually feels good in that autonomous workflow. It is more predictable, easier to steer mid-task, and more trustworthy when the job spans multiple files and decisions.
GPT-5.3-Codex surpasses its predecessor as well as the newly released Claude Opus 4.6 (65.4 percent) by about twelve percent in the agentic coding benchmark Terminal-Bench 2.0
Compared to prior Codex models, it's more token-efficient and approximately 25% faster.
Terminal-Bench 2.0 jumped from 64.0% for GPT-5.2-Codex to 77.3% for 5.3.
