Pros & Cons
Gemini 3.8 Flash
- Industry-leading 90.8% on Terminal-Bench 2.1 for autonomous shell & terminal coding
- Record-breaking throughput (348 tok/s high thinking, up to 620 tok/s burst)
- 1.0M native multimodal context window accepting 1 hour of video & full codebases
- Extremely competitive pricing ($0.75 input / $3.75 output per 1M tokens)
- 64,000 max output tokens for full multi-file code synthesis in a single turn
- Proprietary hosted API without open weights for on-prem self-hosting
- Thinking trace mode increases latency compared to raw zero-shot completion
Muse Spark 1.3
- Dual Max and XHigh execution profiles for adaptive latency/reasoning balancing
- Permissive open-weights license for self-hosting on private cloud hardware
- Seamless integration with Meta's Muse Code developer environment
- Fast 245 tokens/second throughput in XHigh profile
- Terminal-Bench 2.1 (84.1%) and DeepSWE (68.2%) lag behind Gemini 3.8 Flash
- Blended API cost ($1.58/M) is 41% higher than Gemini 3.8 Flash ($1.12/M)
- No native video or audio ingestion capabilities
Frequently Asked Questions
What is the difference between Muse Spark 1.3 Max and XHigh?
Muse Spark 1.3 features two execution profiles: XHigh is optimized for rapid generation (245 tok/s) with low latency, while Max utilizes deeper reasoning iterations for complex software refactoring and difficult math problems.
Is Gemini 3.8 Flash cheaper than Muse Spark 1.3?
When using hosted cloud APIs, yes. Gemini 3.8 Flash costs $0.75 input / $3.75 output ($1.12/M blended), while Muse Spark 1.3 API costs $0.50 input / $2.20 output ($1.58/M blended). However, Muse Spark 1.3 weights can be downloaded and self-hosted for free.
Does Muse Spark 1.3 support video analysis?
No. Muse Spark 1.3 currently supports text and static images. Gemini 3.8 Flash natively supports both video (up to 1 hour) and audio files.
Final Takeaway
Choose Muse Spark 1.3 if you require open-weights flexibility for private enterprise clusters, native integration with Meta's Muse Code developer ecosystem, or the ability to switch dynamically between Max reasoning and XHigh latency profiles. Choose Gemini 3.8 Flash for unmatched raw throughput (348–620 tok/s), industry-leading autonomous shell execution (90.8% Terminal-Bench), native video processing, and 29% lower API pricing ($1.12/M vs $1.58/M).
Detailed In-Depth Analysis
Open Weights Innovation vs Cloud-Native Acceleration
Both Gemini 3.8 Flash and Muse Spark 1.3 landed in September 2026 as answer to developers demanding faster, smarter, and cheaper models:
- Meta's Dual-Engine Innovation: Muse Spark 1.3 introduces a novel dual-engine profile:
- XHigh Engine: Focuses on raw throughput, achieving 245 tokens per second for quick autocomplete and inline code edits.
- Max Engine: Engages deeper multi-path reasoning for intricate debugging, scoring 68.2% on DeepSWE v1.1.
- Because Meta releases the model under an open license, organizations can host both profiles on private enterprise infrastructure.
