KAT-Coder-Pro V2 — KAT text model with an Intelligence Index of 34, a 262K-token context window and a blended price of $0.22/1M tokens (open weights).
Muse Spark 1.1 vs KAT-Coder-Pro V2: Muse Spark 1.1 scores higher on the Intelligence Index. Muse Spark 1.1 leads overall capability (Intelligence Index 51.0 vs 34.0). KAT-Coder-Pro V2 is the cheaper model to run at $0.22/1M blended tokens — about 2.8× cheaper.
Capability: intelligence, coding and agentic work
On the composite Intelligence Index the Muse Spark 1.1 scores 51.0 versus 34.0. For software development, the Coding Index puts Muse Spark 1.1 ahead (71.3 vs 59.5). On agentic, multi-step tool-use tasks, Muse Spark 1.1 measures stronger. Composite indices summarize many evaluations, but always test on your own workload before committing.
Context window and speed
The Muse Spark 1.1 accepts up to 1 million tokens per request, which sets how much documentation, transcript or code it can reason over at once.
Pricing and access
At blended per-token rates, KAT-Coder-Pro V2 is the cheaper model to run ($0.22 vs $0.62 per 1M tokens). Muse Spark 1.1 is proprietary api and KAT-Coder-Pro V2 is open weights. Open-weight models can be self-hosted, trading per-call cost for infrastructure you manage; for production also weigh rate limits, throughput and data-residency requirements.
The verdict
Both are credible choices in the ai model comparison space; the specification table above lays out every metric so you can weigh the trade-offs that matter to you. Pick the one whose strengths line up with how you will actually use it.

Methodology
Large language models are compared on independent leaderboard metrics: an Intelligence Index (a composite of reasoning and knowledge evaluations), Coding and Agentic indices where measured, community arena Elo, maximum context window, a blended API price per million tokens (weighted across cache-hit, input and output rates), and measured output speed in tokens per second. Where a model ships multiple reasoning-effort variants, we report its strongest variant. Benchmarks capture only part of real-world quality, which also depends on tool use, latency, safety and task fit — and this space moves quickly, so figures reflect the leaderboard snapshot on the page date.
