The Contenders – Overview
| Model | Company | Release | Key Strengths |
|---|---|---|---|
| Muse Spark | Meta | April 2026 | Efficiency, native multimodality, Contemplating mode, ecosystem integration |
| ChatGPT (GPT‑5.4) | OpenAI | March 2026 | Conversational fluency, coding, creativity, large context |
| Gemini 3.1 Pro | February 2026 | Abstract reasoning, factual accuracy, Google ecosystem |
All three are available for free with usage limits, and each offers a paid tier for higher usage and advanced features.
Benchmark Performance – Who Is Smartest?
According to the Artificial Analysis Intelligence Index v4.0, the models rank as follows:
| Benchmark | Muse Spark | GPT‑5.4 | Gemini 3.1 Pro |
|---|---|---|---|
| MMLU (general knowledge) | 90.1% | 92.4% | 92.8% |
| GPQA Diamond (grad science) | 89.5% | 92.8% | 94.3% |
| ARC AGI 2 (abstract reasoning) | 42.5% | 76.1% | 76.5% |
| Humanity’s Last Exam | 58% | 62% | 61% |
| FrontierScience | 38% | 41% | 42% |
Verdict: Gemini 3.1 Pro leads on most complex reasoning tasks. GPT‑5.4 is close behind. Muse Spark trails on abstract reasoning but holds its own on general knowledge and scientific reasoning.

Multimodal Capabilities – Seeing, Hearing, Understanding
| Feature | Muse Spark | GPT‑5.4 | Gemini 3.1 Pro |
|---|---|---|---|
| Native multimodal | ✅ (text, image, audio, video) | ❌ (stitched) | ✅ |
| Visual chain of thought | ✅ (annotates images) | ❌ | ❌ |
| Audio understanding | ✅ | ❌ | ✅ (limited) |
| Video (short clips) | ✅ | ❌ | ✅ |
| Health training (physicians) | ✅ (1,000+) | ❌ | ❌ |
| Interactive overlays | ✅ | ❌ | ❌ |
Verdict: Muse Spark wins on multimodal innovation, especially visual chain of thought and health‑specific training. Gemini supports native multimodality but lacks visual reasoning annotations. GPT‑5.4 is stitched and cannot natively process audio or video.
For examples, see our Muse Spark Multimodal Capabilities guide.
Agentic and Reasoning Features
| Feature | Muse Spark | GPT‑5.4 | Gemini 3.1 Pro |
|---|---|---|---|
| Parallel agentic reasoning | ✅ (Contemplating mode) | ❌ | ❌ |
| Deep Think / Pro mode | ✅ (Thinking mode) | ✅ | ✅ |
| Tool use (web, code, etc.) | ✅ | ✅ | ✅ |
| Long context (tokens) | 128K | 256K | 1M (Gemini 1.5 Pro) |
Verdict: Muse Spark’s parallel agents are unique, but Gemini’s 1M token context (for Gemini 1.5 Pro) is unmatched for processing very long documents. GPT‑5.4 offers a solid balance.
Efficiency and Cost
| Metric | Muse Spark | GPT‑5.4 | Gemini 3.1 Pro |
|---|---|---|---|
| Compute efficiency | 10x less than Llama 4 | Moderate | Moderate |
| Free tier | Yes (rate‑limited) | Yes | Yes |
| Paid tier (monthly) | Not yet announced | $20 | $20 |
| API cost per 1M tokens | Not yet public | $10 (input), $30 (output) | $5 (input), $15 (output) |
Verdict: Muse Spark has the potential to be the cheapest to serve, but pricing is not yet public. Currently, Gemini offers the lowest API costs.

Ecosystem Integration – Where You Can Use Each
| Platform | Muse Spark | ChatGPT | Gemini |
|---|---|---|---|
| Web | meta.ai | chat.openai.com | gemini.google.com |
| Mobile app | Meta AI app (iOS/Android) | ChatGPT app | Gemini app |
| Smart glasses | ✅ (Ray‑Ban Meta) | ❌ | ❌ |
| Social media integration | ✅ (Facebook, Instagram, WhatsApp) | ❌ | ❌ |
| Google Workspace | ❌ | ❌ | ✅ (Docs, Gmail, Drive) |
| Microsoft 365 | ❌ | ✅ (Copilot) | ❌ |
Verdict: Choose based on where you live. Meta AI is best for social media users. Gemini excels for Google Workspace. ChatGPT integrates with Microsoft 365.
Real‑World Applications – Which Model for What Task?
| Task | Best Model | Why |
|---|---|---|
| Casual chat, writing | ChatGPT | Most conversational, creative |
| Research, complex reasoning | Gemini 3.1 Pro | Highest abstract reasoning scores |
| Visual troubleshooting (home repair, cooking) | Muse Spark | Visual chain of thought, annotations |
| Long document analysis | Gemini 1.5 Pro | 1M token context |
| Coding | GPT‑5.4 / Gemini | Both strong |
| Health and nutrition | Muse Spark | Trained with 1,000+ physicians |
| Travel planning | Muse Spark (Contemplating mode) | Parallel agents explore multiple angles |
| Budget‑conscious API | Gemini | Lowest per‑token cost |
