“Most importantly, other companies like Anthropic and Google caught up; xAI and various Chinese companies aren’t far behind.”
Our reading, the sentence that was checked:
Anthropic and Google have caught up with OpenAI, and xAI and Chinese companies are not far behind.

From the speaker
- Anthropic and Google caught up
- xAI and various Chinese companies
- aren’t far behind
Our interpretation
- In context, caught up refers to language-model capabilities relative to OpenAI, not revenue, customer numbers, or infrastructure.
- The ordinary reading is that Anthropic and Google compete in OpenAI's leading capability tier, while xAI and multiple Chinese suppliers offer competitive models within reach of that tier.
- It does not require identical scores or leadership on every task.
- Use the latest completed quarter and the partial quarter before publication, October 1, 2025 through January 13, 2026, to assess the ongoing state.
Counts as supported if: Independent comparisons across varied tasks place Anthropic and Google alongside OpenAI, with xAI and at least two Chinese providers competitively positioned near the leading group.
Counts as contradicted if: Broad, comparable evaluations show a clear systematic capability separation inconsistent with those tier descriptions.
Retrospective: these criteria were written after the outcome was public.
Current assessment
Was it true for the period described?
Outcome: Supported
The dated evidence matches what the claim committed to, under the criteria frozen before grading.
Scored on a plain reading. The speaker named no measure for this claim, so it was judged on the reading an informed reader would take, stated below under our interpretation. Both reviews had to find that reading fair.

Rationale
Late-2025 independent evaluations put Anthropic alongside OpenAI and Google ahead on the same multi-task index. xAI and Moonshot were close competitors, and MiniMax supplied another competitive Chinese model. The year-end report, including GPT-5.2, still describes a contested frontier. This supports the ordinary capability-tier reading. It does not establish equal performance everywhere: OpenAI retained the year-end lead, and gaps varied by supplier and task.
Limitations
- The result depends on the ordinary competitive-tier reading of caught up and not far behind.
- MiniMax was further behind than Moonshot in the cited November comparison.
- The year-end report was published after the post but before the evaluation cutoff and explicitly assesses 2025 models.
- Different benchmark versions are treated separately, without numerical cross-version comparisons.
Evidence (3 items)
Supports the claim: Artificial Analysis,
second most intelligent model
Why it matters here: The accompanying comparison gives Claude Opus 4.5 and GPT-5.1 scores of 70, Gemini 3 Pro 73, Grok 4 65, and Kimi K2 Thinking 67 on the same index. This supports the leading-tier comparison and xAI's competitive position.

Supports the claim: Artificial Analysis,
achieves a 67
Why it matters here: The report places Kimi second only to GPT-5 and records MiniMax M2 at 61. These are two Chinese suppliers with competitive multi-task results, although MiniMax's larger gap makes the phrase not far behind less precise.

Supports the claim: Artificial Analysis,
fiercely contested
Why it matters here: This retrospective assessment includes GPT-5.2 and still identifies a contested leading group. It also retains OpenAI as the year-end leader, so it supports competitive parity in the ordinary sense rather than exact equality.
