I wonder why they didn't compare with GPT-5.6-sol, only Terra?

Clearly they're positioning it as a mid model.

Which is in itself a bit weird as mid models nowadays are a golden mean fallacy. Terra is much less popular than both Luna (cost-sensitive) and Sol (performance-sensitive).

Claude Sonnet is a weird exception to the mid models because Anthropic doesn't do much with Haiku and Opus is too big.

Their bigger model is not ready - watermelon code name was still being prepared for release as of a month ago

This is a nice release and a solid improvement over Spark 1.1. It compares favorably with Grok 4.5. Not SOTA, but solid releases. I think they need to really get this more competitive with Deepseek V4 Flash / Luna pricing to move the needle.

If anyone from Meta is reading, please can you publish the cost and latency for each of your benchmarks, like OpenAI does? Show us how the reasoning effort level affects them in 2D charts. This needs to become standard practice.

Theres no actual evidence they didn't just distill Kimi K3

At this point, it doesn't matter who is distilling from who.

Does this muse code have any muse spark 1.2 usage included? Can't understand from the docs.

Interesting, it seems like their muse code is built upon Codex CLI?

Very interesting they have a way cheaper "contributor" version "used to improve our products", how much of that is price discrimination vs the data being that valuable?

Roughly DeepSeek V4 Flash pricing, though you can get V4 from providers that don't train on your data

Pricing: https://dev.meta.ai/docs/pricing-rate-limits

Interesting that they have separate API pricing for "we can train on your data" (whereas iirc most of the big players either make that distinction only between subscriptions and API usage, or train on everything). Wonder how it compares to Deepseek V4 Flash given that they're similar on pricing and data policy.
