What the current evidence supports

Human editorial judgment · 2026-07-21

Track; not yet

Why
Genuinely differentiated on cost and token efficiency (4.2x fewer output tokens than Opus 4.8 on agentic tasks, $2/$6 per-million pricing vs $5/$25 for Opus 4.8) and notable for training partly on real Cursor developer session data, but it trails the top three coding models on raw SWE-bench Pro capability, is not yet available in the EU, its fastest inference path is not yet deployed, and its most publicized capability claim (a math breakthrough) is unverified — too many open threads for adoption today.
Next
Re-evaluate once EU access opens, xAI's native GB300 inference stack ships (claimed to double+ current throughput), and the viral hypercontractivity math claim either gets a peer-reviewed writeup or is dropped/retracted; re-check independent benchmark position (Artificial Analysis Intelligence Index) against Opus/Fable/GPT lineage at that point.
