GLM 4.6 is Zai-org’s new generation flagship model, offering significant advancements over its predecessor GLM 4.5. It boasts a longer context window, enabling it to handle more extensive data. Additionally, its superior coding performance allows developers to work more efficiently, while advanced reasoning capabilities elevate its ability to tackle complex tasks. With more capable agents, GLM 4.6 can perform a broader range of operations autonomously.
In this article, we’ll review the performance of GLM 4.6 and explore the top 3 API providers—Novita, GMI, and Parasail—and compare their key features, performance, and pricing to help you choose the right fit for your development needs.
What is GLM 4.6?
GLM 4.6 is Zhipu AI’s newly released open-source large language model, delivering state-of-the-art performance in multiple domains.
Basic Information of GLM 4.6
| Specification | Details |
|---|---|
| Parameters | 355B |
| Architecture | Mixture-of-Experts |
| Context window | 200K tokens (204,800) |
| Languages | English, Chinese |
Benchmark and Performance Highlights
- Expanded Context Window: The context window has increased from 128K to 200K tokens, allowing the model to handle more intricate agentic tasks.
- Enhanced Coding Performance: GLM-4.6 excels on code benchmarks, showing superior real-world performance in applications like Claude Code, Cline, Roo Code, and Kilo Code, including notable improvements in generating polished front-end pages.
- Improved Reasoning: The model demonstrates a significant boost in reasoning capabilities and supports tool usage during inference, resulting in stronger overall performance.
- More Advanced Agents: GLM-4.6 enhances tool usage and search-based agents, integrating more seamlessly into agent frameworks for improved functionality.
How to Choose the Right API Provider?
- Context Length (Higher is better): Represents the amount of text the model can process in one pass. Longer context windows enable richer document summaries, extended conversations, and more advanced reasoning.
- Token Cost (Lower is better): Indicates the cost per token processed. Lower token costs make large-scale queries and workloads more affordable and scalable.
- Latency (Lower is better): Refers to the delay in response time. Reduced latency ensures smoother interactions, which is crucial for chatbots, assistants, and real-time applications.
- Throughput (Higher is better): Measures how many requests the model can handle concurrently. Higher throughput ensures consistent performance, especially under heavy load or enterprise-level demand.
GLM 4.6 API Provider Comparison
| Provider | Context Length | Input/Output Price | Output Speed (Tokens per sec) | Latency | Fuction Calling |
| Novita AI | 205K | $0.6/$2.2 per 1M Tokens | 62 | 0.73s | ✅ |
| Parasail | 203K | $0.6/$2.1 per 1M Tokens | 43 | 0.62s | ✅ |
| GMI | 205K | $0.6/$2.0 per 1M Tokens | 76 | 1.28s | ✅ |
Novita AI offers the best overall value, combining strong medium coding performance with competitive pricing and fast response times, making it an ideal choice for developers needing reliable, scalable solutions. Parasail stands out for its low latency, but its performance in larger tasks lags behind, making it more suitable for real-time applications with less complexity. GMI provides consistent performance, though its higher latency makes it less efficient for time-sensitive applications, positioning it as a reliable option for general tasks but not the fastest or most scalable choice.
