đź“ş Video Review
With Claude Code facing increasing restrictions and OpenClaw users seeking reliable alternatives, the search for affordable AI coding plans has intensified. After Anthropic’s coding plan became effectively unusable for many OpenClaw deployments, developers are scrambling to find replacements that don’t break the bank.
I tested three major alternatives—MiniMax, Z.ai’s GLM Coding Plan, and Kimi—to see which ones actually deliver on their promises. Here’s what I discovered after real-world usage.
The Problem: Why Anthropic No Longer Works for OpenClaw
Before diving into the alternatives, let’s address the elephant in the room. Anthropic’s coding plan, while powerful, has become increasingly problematic for OpenClaw users. Whether due to API restrictions, rate limiting, or compatibility issues, many developers have found themselves locked out or facing degraded performance.
This created an urgent need: find a coding-focused AI plan that works seamlessly with OpenClaw without requiring enterprise-level budgets.
Alternative #1: MiniMax — The Overhyped Disappointment
Verdict: Not recommended. Cancelled subscription.
MiniMax entered the market with significant hype, promoted heavily across YouTube and tech communities as a Claude killer. I subscribed and tested it for approximately one week. The experience was underwhelming.
The Issues
Prompt Following: MiniMax consistently failed to follow instructions accurately. Instead of executing tasks as specified, it would go off-script or misinterpret requirements.
Hallucination Problems: Most concerning was the tendency to “lie”—not through misunderstanding or memory issues, but through generating false information presented as fact. This is unacceptable for coding workflows where accuracy is critical.
Performance Comparison: In practical terms, MiniMax performed comparably to GPT-5.4 mini or nano—fine for basic tasks, but nowhere near the capabilities needed for serious development work.
The Bottom Line
I stopped using MiniMax within two days of subscribing. While I have remaining credit and will test it in other environments, my initial assessment is clear: this is not a viable replacement for Claude Code. The subscription will not be renewed.
Pricing: Competitive on paper, but irrelevant if the model doesn’t perform.
Alternative #2: Z.ai GLM Coding Plan — The Clear Winner
Verdict: Highly recommended. My new primary coding model.
After the MiniMax disappointment, I turned to Z.ai (formerly Zhipu AI) and their GLM Coding Plan. The difference was immediate and significant.
The Journey: GLM 4.7 to GLM 5.1
I started with the $10/month Lite plan using GLM 4.7. Even at this entry level, performance was noticeably superior to MiniMax. Prompts were followed correctly, code generation was accurate, and the model handled tool use competently.
After seeing the results, I upgraded to access GLM 5.1—and this is where things get interesting.
Why GLM 5.1 Stands Out
Benchmark Performance: According to independent evaluations, GLM 5.1 achieves 77.8% on SWE-bench Verified, placing it within 3 points of Claude Opus 4.6 (80.8%) and GPT-5.2 (80.0%). For an open-weights model at this price point, this is exceptional.
Real-World Usage: GLM 5.1 now serves as my primary model alongside Codex in OpenClaw instances. It handles content generation, complex coding tasks, tool integration and orchestration, and multi-file project management.
Speed and Reliability: The model generates over 55 tokens per second, providing real-time interaction without the network restrictions or account bans that plague some alternatives.
Pricing That Makes Sense
| Plan | Price | Features |
|---|---|---|
| Lite | $10/month | ~400 prompts/week, access to GLM 4.7, 4.6, 4.5 |
| Pro | $30/month | ~2,000 prompts/week, includes GLM 5.1 access |
| Max | Higher tier | Full feature set, maximum quotas |
Compare this to Claude Max at $100-200/month. The value proposition is clear.
What You Get
- GLM 5.1, GLM 5-Turbo, GLM 4.7, GLM 4.6, GLM 4.5 access
- Vision Understanding for image-based coding
- Web Search MCP and Web Reader MCP
- Zread MCP for enhanced research capabilities
- Support for Claude Code, Cline, OpenCode, and other major IDEs
The Technical Edge
GLM models are built on a 744B parameter Mixture-of-Experts architecture (40-44B active per token), trained on 28.5 trillion tokens. The models support 200K context windows and 131K max output tokens—enough for substantial codebases and complex projects.
The coding-specific post-training shows: GLM 5.1 scored 45.3 on coding benchmarks (up from 35.4 on GLM 5), representing a 28% improvement purely through enhanced training methodologies.
My recommendation: If you’re looking for a Claude alternative for OpenClaw, start here.

Alternative #3: Kimi — The Content Generation Specialist
Verdict: Excellent for specific use cases, especially content and budget-conscious users.
Kimi takes a different approach. Rather than offering a coding-specific plan, they provide a comprehensive $15-20/month plan that includes access to all their tools—including Kimi Code, their coding platform.
What Makes Kimi Different
Unified Credit System: One subscription covers everything—Kimi Code, slide creation, sheet generation, research tools, and more. You spend from a single pool of credits across all services.
Cost Efficiency: Kimi is remarkably cheap to run. I’ve been operating an OpenClaw instance primarily on Kimi since the beginning, and the credit consumption is minimal. One factor making it economical: excellent caching that reduces redundant token usage.
Content Generation: Where Kimi really shines is content creation. For affiliate marketers, bloggers, and content-heavy workflows, Kimi generates high-quality text efficiently.
The Trade-offs
While Kimi works well for coding, it’s not specifically optimized for it like the GLM Coding Plan. The K2.5 model scores 76.8% on SWE-bench Verified—competitive but slightly behind GLM 5.1’s 77.8%.
However, Kimi’s Agent Swarm capability (up to 100 sub-agents working in parallel) offers unique advantages for complex multi-step tasks that require coordination across different domains.
Best For
- Budget-conscious users who need coding AND content generation
- Developers who want slide creation, sheets, and research tools bundled
- Users who value the flexibility of a unified credit system
- Content-heavy workflows where AI assistance spans multiple formats
Side-by-Side Comparison
| Feature | MiniMax | Z.ai GLM | Kimi |
|---|---|---|---|
| SWE-bench Verified | ~56% | 77.8% | 76.8% |
| Starting Price | Variable | $10/month | $15/month |
| Coding Optimization | Poor | Excellent | Good |
| Context Window | Unknown | 200K | 256K |
| OpenClaw Compatible | Yes | Yes | Yes |
| Vision Support | Limited | Yes | Yes |
| Tool Use | Unreliable | Excellent | Good |
| Content Generation | Poor | Good | Excellent |
Final Recommendations
For Pure Coding: Z.ai GLM Coding Plan
If your primary need is coding within OpenClaw, GLM 5.1 is the clear choice. The combination of near-Claude performance, affordable pricing, and OpenClaw compatibility makes it the best Anthropic alternative currently available.
Start with: Lite Plan ($10/month) to test GLM 4.7, then upgrade to Pro ($30/month) for GLM 5.1 access if satisfied.
For Budget + Content: Kimi
If you need coding capabilities alongside content generation, slides, and research tools—and want to minimize costs—Kimi offers unbeatable value. The unified credit system and caching efficiency make it surprisingly affordable for sustained usage.
For MiniMax: Skip It
Based on my testing, MiniMax is not ready for production coding workflows. The hallucination issues and poor instruction following make it unreliable for serious development work.
The Bigger Picture: The Democratization of AI Coding
What’s happening here reflects a broader trend: the monopoly on high-performance coding AI is breaking. Models like GLM 5.1 prove that open-weights alternatives can approach closed-source frontier performance at a fraction of the cost.
For OpenClaw users, this is liberation. No longer dependent on a single provider, developers can now choose from multiple capable alternatives, mix and match based on specific needs, and avoid vendor lock-in.
The future of AI-assisted coding isn’t a single dominant platform—it’s a diverse ecosystem where users select the right tool for each job.
