Claims ✓4 ~1 ✗0 ?0 · 14 reports
The open weights, the shared text-image-audio space and the code gains check out in independent tests; text-only users get no boost, as Google said.

DeepSeek-V4.1-Flash-1017
Claims ✓2 ~2 ✗0 ?0 · 12 reports
It is live and MIT-licensed as promised, but users split on whether it finishes faster and codes better; some see shorter runs, others overthinking.
Partly

No. 005 · Google · launched 13 Oct 2026 · stamped 22 Oct 2026
Gemini 4 Argon
Claims ✓0 ~2 ✗1 ?1 · 10 reports
It is live in the API and Gemini app, but the advertised 95% cache discount gave users zero cache hits, and many Pro and Business subscribers still can't use it in Antigravity.
Partly

No. 002 · Anthropic · launched 22 Sept 2026 · stamped 22 Oct 2026
Claude Opus 5.5
Claims ✓0 ~3 ✗0 ?2 · 7 reports
The lower list price is real, but users report limits draining faster, more thinking tokens and safeguard false alarms, and nobody has independently confirmed the 40% saving.
Partly

GPT-6.1 Sol
Claims ✓0 ~3 ✗0 ?2 · 5 reports
It arrived and Ultrafast followed, but 'available today' took app updates for many users, Ultrafast is limited to top plans, and some users report over-refusals.

Muse Spark Open
Claims ✓0 ~1 ✗0 ?3 · 6 reports

LFM3

GPT-6.1 Terra
Claims ✓0 ~0 ✗0 ?4 · 1 reports
