Claude Fable 5 returns as model rankings shift

Claude Fable 5 returned to global access on July 1, 2026 after a US export-control directive forced Anthropic to suspend Fable 5 and Mythos 5 globally on June 12, 2026. Fable 5 is again ranked as the top publicly available model, supported by scores including 80.3% on SWE-bench Pro and 95% SWE-bench Verified, though it now carries a tighter safety classifier and updated export-use terms.

Claude Sonnet 5, launched on June 30, 2026, has become the stronger default for many production workloads because of its price-performance profile. It scores 63.2% on SWE-bench Pro, beats Claude Opus 4.8 on Terminal-Bench 2.1 at 80.4% vs 74.6%, and is priced at $2/$10 per million tokens through August 31, 2026.

OpenAI’s GPT-5.6 Sol, Terra, and Luna remain in limited preview for approximately 20 trusted partner organizations, with general availability expected in mid-July 2026. GLM-5.2 leads the open-weight coding category with 62.1% on SWE-bench Pro, a 1M token context window, MIT licensing, and hosted pricing of $1.40/$4.40.
