Scores out of 100 — how we evaluate models. “Est. month” is 10M in / 2M out at list price: a ceiling, no discounts.
Why each one is on the shortlist for muse glimmer 30B alternatives, what it is genuinely good at, and where we would steer you away from it.
Ranked first here for muse glimmer 30B alternatives: 100/100 on coding, with the widest margin of anything in this line-up.
Anthropic's September 1, 2026 frontier release and the new capability ceiling for coding, agents, and scientific work. Base pricing is unchanged at $10/$50, but cache reads dropped 75% to $0.25/1M — roughly 25% cheaper on typical workloads and up to 45% cheaper on agentic ones. 1M context, 128K output, adaptive thinking always on.
You need low latency, or your workload is uncached and cost-sensitive — Claude Opus 5 is half the base price and within a few points on agentic coding.
The new frontier leader, and the rare upgrade that costs less than the model it replaces. Base $10/$50 pricing did not move, but a 75% cut to cache reads makes typical workloads ~25% cheaper than Fable 5 and heavily agentic ones ~45% cheaper — while more than doubling Fable 5 on agentic science and beating Opus 5 on agentic coding. If you were already on Fable 5, switching is a straight win. If you were on Opus 5 for the price, it still costs 2x on uncached tokens.

The fastest model in this shortlist for muse glimmer 30B alternatives. Pick it when turnaround is what your readers or users notice.
Meta's return to genuine open source — a 30B dense model under Apache 2.0, built for always-on agents rather than chat, and the first release from Meta Superintelligence Labs.
You need a large context window or the strongest agent scores at this size — check Qwen's 27B first.
The best Apache 2.0 agent model you can run on consumer hardware right now. Pick it when licence freedom and local execution matter more than the last few benchmark points — otherwise Qwen3.6-27B edges it on agent tasks.

Claude Fable 5.1 is the strongest overall alternative. It scores 100/100 on coding (Muse Glimmer 30B: 80/100) and costs $10/1M input vs $0.35/1M. New frontier leader — better than Fable 5 on every published benchmark, and cheaper to run.
GPT-5.6 Luna at $0.2/1M input — 43% cheaper than Muse Glimmer 30B's $0.35/1M. It scores 88/100 on coding, so expect a quality step down on the hardest tasks.
Yes — Kimi K3 is the strongest open-weight replacement for Muse Glimmer 30B, scoring 96/100 on coding against Muse Glimmer 30B's 80/100. You can self-host it or run it through hosted APIs at $3/1M input (Muse Glimmer 30B costs $0.35/1M), with no per-seat subscription. Self-hosting trades the licence saving for infrastructure you have to run, so it pays off at sustained volume rather than for occasional use.
Muse Spark — same provider, same API surface, $1.25/1M input vs $0.35/1M. Best-value multimodal agentic model — GPT-5.5-tier smarts, video/audio/PDF in.
