Muse Wonder vs Spark 1.3: Should You Upgrade?
Last verified: October 28, 2026 · Sources: Artificial Analysis (Intelligence Index v4.3, cost per task), vendor announcements
Searching "muse spark wonder" or deciding between Meta's two model lines? This page compares Muse Spark 1.3 (the previous generation) with Muse Wonder (and Wonder Full) so you can decide whether the ~3x cost jump is worth it.
Quick verdict
Spark 1.3 costs $1.60 per average task; Muse Wonder costs $4.52 — nearly 3x. In return you get 8 more Intelligence Index points on the base model (52 vs 48), 8 more on Full (56), the Active Memory / Active Focus agent features, ~1M context, multimodal input, and (with Muse Code) a coding-agent score of 68. Upgrade if you run agents or coding workflows where failure and forgetfulness are expensive; stay on Spark if your tasks are simple, high-volume and cost-dominated.
Side-by-side comparison
| Spark 1.3 | Muse Wonder | Muse Wonder Full | |
|---|---|---|---|
| Position | Meta's previous generation | New base frontier model | Reasoning-max variant |
| AA Intelligence Index v4.3 | 48 | 52 | 56 |
| Avg cost per task | $1.60 (3x cheaper) | $4.52 | |
| Context window | — | ~1M tokens (1,048,576) | |
| Input | — | Text, image, video, audio, PDF | |
| Agent features | — | Active Memory, Active Focus | |
| Coding-agent index | — | — | 68 (with Muse Code) |
| Reasoning effort | — | Adjustable up to max (note: max effort ≠ Full) | |
What ~3x per task actually buys
The cost-per-task jump from $1.60 to $4.52 is the single most important number for existing Meta users. Here is what the premium delivers, and what it does not:
Real gains
- +8 Intelligence Index points (48 → 56 on Full) — meaningful on complex, multi-step work
- Active Memory — context, preferences and decisions persist across sessions; Spark has no equivalent
- Active Focus — retries alternate paths when blocked instead of failing the task
- ~1M-token multimodal context — text, image, video, audio and PDF together
- Coding agents — Wonder Full + Muse Code hits 68, tied with Sonnet 5.5 + Claude Code
Not gains
- Factual knowledge stays weak (AA-Omniscience 30) — do not upgrade hoping for better trivia
- Raising reasoning effort to max does NOT turn Wonder into Full — Full is a separate model, only via Muse Code subscriptions
- Simple tasks — high-volume classification, extraction and routing often score the same at 3x the price
The upgrade decision tree
| Your workload | Verdict |
|---|---|
| Agents that fail mid-task and forget users | Upgrade — Active Memory/Focus target exactly this |
| Coding agents (via Muse Code) | Upgrade — 68 coding-agent score |
| Long multimodal documents | Upgrade — ~1M context + video/audio/PDF input |
| High-volume simple tasks | Stay on Spark 1.3 — $1.60/task |
| Knowledge-heavy Q&A | Neither is great — consider Opus 5.5 (Omniscience 46) |
