The later card adds technical context to the launch; it is not a second launch date. Together these primary documents support a historical account of researched synthesis, rather than a claim about today’s access, limits or model configuration."

For high-consequence work, separate source collection from claim validation: first identify what the page actually says, then test whether it supports the decision being proposed. This distinction also exposes conflicting evidence instead of averaging it into prose."

      "paragraphs": [
        "Editorial analysis: a long report can look authoritative even when its evidence path is thin. The useful unit of review is a claim with a source, scope and confidence note. Deep-research tools can reduce collection effort, but a team still needs subject expertise to judge data provenance, omitted counterexamples and whether a cited source applies to the problem at hand.",
        "The February release described deep research as an agent using a web-browsing- and data-analysis-optimized version of o3 to find, interpret and synthesize text, images and PDFs. OpenAI said a run could take tens of minutes, examine hundreds of online sources and return a documented report with citations and a summary of its thinking. That means a citation is an output field attached to a long retrieval path, rather than a guarantee that the conclusion is correct.",
        "A rigorous fixture should retain the input question, source set, retrieval time and final report so a reviewer can replay the chronology. It should also test a PDF with a misleading cover date and a source that disappears during a run. Those cases reveal whether the report distinguishes publication evidence, access failure and contradictory evidence instead of flattening all three into prose.",
        "The stated target domains included finance, science, policy and engineering, where source dates, PDF versions and primary authority often determine whether a synthesis remains useful."
