Muse Spark 1.1 has a published SWE-bench Verified score of 82%. Qwen3.5-9B does not have that eval on this page yet.
Muse Spark 1.1 supports a 1M token context window, while Qwen3.5-9B supports 262K tokens. Muse Spark 1.1 offers a larger context window. Filling a larger window bills more input tokens, so the cheaper-per-million model can still cost more on long documents.
Muse Spark 1.1 leads on 3 of 3 shared benchmarks versus Qwen3.5-9B's 0 wins. Check the comparison table for GPQA Diamond, SWE-bench, MMLU, HLE, and the other evals we track. Token price and benchmark score together are the usual LLM comparison, not either number alone.
Both Muse Spark 1.1 and Qwen3.5-9B are production API models. For cost-sensitive production traffic, Qwen3.5-9B has better economics on the blended 1M-in + 1M-out scale. For maximum capability, weight the benchmark table for your domain. Many production stacks route cheap models for drafts and a frontier model for the hard turn, which is usually cheaper than sending everything to the expensive API.
Yes. Call Muse Spark 1.1 through Meta and Qwen3.5-9B through OpenRouter with separate API keys, or through a gateway that already wraps both. Keep prompts in tokens, not characters, when you estimate the invoice. AnotherWrapper templates can swap providers without rewriting auth and billing.
List rates are the latest published Meta API pricing and OpenRouter API pricing, quoted per million tokens. Official rate sheets: https://llama.meta.com/ and https://openrouter.ai/api/v1/models. Prompt caching, batch APIs, and committed-use discounts can change the invoice. Benchmark scores are from official publications and independent evals, updated as new numbers land.
Muse Spark 1.1 supports up to 131K output tokens per request, while Qwen3.5-9B supports up to an unspecified number of output tokens. Output tokens are usually the expensive half of API pricing, so a higher max output cap is a capability, not a discount.
Muse Spark 1.1 has a measured throughput of approximately 6.152425085592334 tokens/second. Throughput data for Qwen3.5-9B is not yet available. Throughput (tokens per second) and time-to-first-token are why two models with the same per-million-token price can still feel different in chat and agents.
