Muse Spark Open itself is stamped Too early: read its receipt.
- 01Delivered
EmbeddingGemma 2
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.
- 02Partly
DeepSeek-V4.1-Flash-1017
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.
- 03Partly
Gemini 4 Argon
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.
- 04Partly
Claude Opus 5.5
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.
- 05Partly
GPT-6.1 Sol
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.
- 06Too early
LFM3
Two days in, only a few first-hand comments exist, and one reports a load failure and a wrong answer.
- 07Too early
GPT-6.1 Terra
Two days in, users have barely tested the cost and speed claims; one early benchmark run found max effort costlier than Sol.
- 08Too early
Gemini 4 Carbon
Access is limited to a subset of cyber defenders, so no hands-on reports exist to check the claims.
- 09Too early
Genie 4
A trusted-tester research preview with a waitlist: no first-hand user reports exist yet to check the realism and audio claims.
