Prices are USD per million tokens at standard rates, excluding batch and caching discounts. Bold indicates the better figure where one is objectively better. Values we could not confirm from the provider are shown as “Not verified” rather than estimated.
Pricing tiers: Grok 4.5: Base tier is $2/$6 per million tokens; prompts above 200K tokens are priced at $4/$12, and web/X search tool calls bill separately. · Muse Glimmer 30B: Apache 2.0 open weights (BF16 + official GGUF); hosted inference billed by provider.
Grok 4.5
SpaceXAI's mid tier, priced below the frontier labs with a large context window and image input.
Best for
- Real-time data queries
- Technical tasks
- Cost-sensitive mid-tier work
Watch out
Token rates double above a 200K-token prompt, and web/X search tool calls bill separately. xAI's current code/chat default is Grok 4.6 at the same $2/$6 band.
Muse Glimmer 30B
Meta's open-weight multimodal agentic model distilled from Muse Spark for local consumer hardware (~24–32GB class with 4-bit).
Best for
- Local agents
- On-device coding + tool use
- Privacy-sensitive multimodal work
Watch out
Full BF16 needs far more than 24GB — plan on official GGUF / 4-bit packs (and mmproj for vision). Agentic quality ≠ frontier Muse Spark API; validate on your workflows.

DeepSWE “Best” picks the highest published reasoning effort per model (not the highest pass rate). Small gaps may not be statistically meaningful — confirm on deepswe.datacurve.ai.
Common questions
Grok 4.5 vs Muse Glimmer 30B
Answered from the verified figures on this page rather than general guidance.
Is Grok 4.5 or Muse Glimmer 30B cheaper for input?
Muse Glimmer 30B is cheaper at $0 per million input tokens, against $2 for Grok 4.5. Output tokens usually dominate a real bill, so weigh the output rate more heavily than the input rate. These are base rates; Grok 4.5 has tiered pricing: Base tier is $2/$6 per million tokens; prompts above 200K tokens are priced at $4/$12, and web/X search tool calls bill separately. Muse Glimmer 30B has tiered pricing: Apache 2.0 open weights (BF16 + official GGUF); hosted inference billed by provider.
Is Grok 4.5 or Muse Glimmer 30B cheaper for output?
Muse Glimmer 30B is cheaper at $0 per million output tokens, against $6 for Grok 4.5. Output tokens usually dominate a real bill, so weigh the output rate more heavily than the input rate. These are base rates; Grok 4.5 has tiered pricing: Base tier is $2/$6 per million tokens; prompts above 200K tokens are priced at $4/$12, and web/X search tool calls bill separately. Muse Glimmer 30B has tiered pricing: Apache 2.0 open weights (BF16 + official GGUF); hosted inference billed by provider.
Which has the larger context window, Grok 4.5 or Muse Glimmer 30B?
Grok 4.5 accepts 500K tokens against 131K for Muse Glimmer 30B. This only matters if you routinely send very long documents or large codebases.
Should I use Grok 4.5 or Muse Glimmer 30B?
Both sit in the balanced tier, so the choice usually comes down to price and context rather than capability. Grok 4.5 suits real-time data queries; Muse Glimmer 30B suits local agents.
Can I self-host Grok 4.5 or Muse Glimmer 30B?
Muse Glimmer 30B publishes open weights, but self-hosting and third-party provider access depend on the licence, hardware, serving support, and availability. Grok 4.5 is a closed model whose supported access paths are controlled by its provider.
Next step
Choosing between them
Tier and workload decide this more reliably than a leaderboard position does.
If both sit in the same tier, the decision usually comes down to context window and output price rather than headline capability — output tokens dominate real bills.
If one is a step up within the same provider, the useful question is whether your hardest task actually fails on the cheaper tier. Most production volume — classification, extraction, summarization — does not.
