Grok 4.20
According to BenchLM.ai, Grok 4.20 ranks #34 out of 119 models on the provisional leaderboard with an overall score of 72/100. It does not yet have enough sourced coverage for BenchLM's verified leaderboard. While not a frontier model, it offers specific advantages depending on the use case.
Grok 4.20 is a proprietary model with a 2M token context window. It uses explicit chain-of-thought reasoning, which typically improves performance on math and complex reasoning tasks at the cost of higher latency and token usage.
Grok 4.20 sits inside the Grok 4.20 family alongside Grok 4.20 Multi-agent. BenchLM links it directly to Grok 4.1 as the earlier related model in that lineage. This profile currently has 18 of 225 tracked benchmarks. BenchLM only exposes non-generated benchmark rows publicly, so missing categories stay blank until a sourced evaluation is available.
Its strongest category is Instruction Following (#4), while its weakest is Multimodal & Grounded (#71). This performance profile makes it a well-rounded choice across a range of tasks.
