OpenClaw crossed 285,000 GitHub stars in March 2026, making it the most-starred open-source project in history. NVIDIA CEO Jensen Huang called it "probably the most important software ever released" at the Morgan Stanley TMT Conference on March 4. Yet the framework itself is just a routing layer — a gateway that connects messaging platforms to an LLM and executes whatever the model tells it to do. The model you plug in determines whether your OpenClaw agent reliably manages emails, fixes code, and browses the web — or sends the wrong message, hallucinates tool calls, and leaks your data to a prompt injection attack. Five models dominate community discussions as of March 2026: MiniMax M2.5, Moonshot AI Kimi K2.5, DeepSeek V3.2, Anthropic Claude Sonnet 4.6, and OpenAI GPT-5.4. This guide compares them across pricing, benchmarks, community feedback, and OpenClaw-specific performance to help you make a practical decision.
Why Model Choice Makes or Breaks Your OpenClaw Agent
Every time you send a command through WhatsApp or Telegram, OpenClaw packages your entire conversation history and sends it to the connected model. The model must understand context, plan a sequence of actions, and produce precisely formatted tool calls for OpenClaw to execute. A malformed JSON schema means a failed action. A forgotten detail from ten turns ago means the wrong file gets modified. A model susceptible to prompt injection means a malicious website can hijack your agent.
The OpenClaw community consistently evaluates models on three dimensions: tool-calling reliability (can it output correct JSON schemas without hallucinating parameters?), long-context coherence (does it remember instructions from earlier in a multi-hour session?), and prompt injection resistance (can it resist malicious instructions embedded in emails or web pages it browses?). Cisco's AI security research team tested a third-party OpenClaw skill in early 2026 and found it performing data exfiltration and prompt injection without user awareness — a reminder that model security is not theoretical.

Model-by-Model Deep Dive
MiniMax M2.5: Best Price-Performance for Coding
Beijing-based MiniMax released M2.5 on February 12, 2026. Its 80.2% SWE-Bench Verified score sits within 0.6 percentage points of Claude Opus 4.6 — at roughly 1/10th to 1/20th the API cost. The model uses a 230B-parameter Mixture-of-Experts architecture with only 10B active parameters per inference pass, keeping latency and cost low.
M2.5 exhibits what MiniMax calls "architect-level thinking" — before writing code, it proactively decomposes project structure, plans architecture, and designs UI layouts. This behavior emerged during reinforcement learning across 200,000+ real-world environments spanning 10+ programming languages. OpenHands confirmed M2.5 as the first open-weight model to exceed Claude Sonnet on their composite index. Kilo Code's autonomous testing showed M2.5 completing three TypeScript tasks in 21 minutes versus GLM-5's 44 minutes, scoring 88.5/100.
Internally, MiniMax reports that 80% of newly committed code at the company is M2.5-generated, and 30% of overall business tasks are autonomously completed by the model.
Best for OpenClaw: High-volume code generation, budget-constrained 24/7 agents, self-hosted enterprise deployments.
Watch out for: Occasional instruction-following lapses (OpenHands noted missed output format tags), smaller 205K context window.
Kimi K2.5: The Only Model with Agent Swarm
Moonshot AI's Kimi K2.5, released January 27, 2026, introduces Agent Swarm — a system that coordinates up to 100 parallel sub-agents trained through Parallel-Agent Reinforcement Learning. The orchestrator dynamically creates specialized sub-agents, decomposes tasks into parallelizable work units, and manages concurrent execution across up to 1,500 tool calls.
Results are dramatic: BrowseComp jumps from 60.6% (standard agent) to 78.4% (Agent Swarm mode). WideSearch improves from 72.7% to 79.0%. Wall-clock time drops by 4.5x. On BrowseComp, K2.5 outperformed GPT-5.2 Pro; on WideSearch, it beat Claude Opus 4.5.
The model's native multimodal architecture — trained on 15 trillion mixed visual and text tokens — enables vision-to-code workflows that text-only models cannot match. Moonshot also released Kimi Code CLI, providing a terminal-based coding experience comparable to Claude Code. Moonshot's valuation has climbed from $2.5 billion to $4.3 billion, with a $5 billion round reportedly in progress.
Best for OpenClaw: Parallel research workflows, frontend development from visual specs, cost-effective high-volume agentic tasks.
Watch out for: SWE-Bench trails Claude/MiniMax by 3–4 points; English prose quality rated ~8.5/10 vs. 9/10 for Claude/GPT; smaller ecosystem compared to Anthropic or OpenAI.
DeepSeek V3.2: Lowest Cost for Daily Agent Tasks
At \(0.28/1M input and \)0.40/1M output tokens, DeepSeek V3.2 is the cheapest option by a wide margin. APIYI platform data shows OpenClaw users averaging \(1–3/month for light daily use. At 100 tokens per second of continuous generation, hourly cost stays under \)0.50.
V3.2 introduces DeepSeek Sparse Attention (DSA) for computational efficiency and achieves GPT-5-class reasoning through scaled reinforcement learning. The high-compute variant, V3.2-Speciale, won gold medals at the 2025 International Mathematical Olympiad and International Olympiad in Informatics. The 164K output window allows single-pass generation of complete modules — useful for OpenClaw agents generating long files or reports.
Best for OpenClaw: Budget-first personal assistants, high-cycle background automation, the "daily driver" in a multi-model strategy paired with Claude or GPT for complex tasks.
Watch out for: API reliability is the biggest pain point — frequent 503 errors and high latency during peak hours require retry logic in your OpenClaw config. Content filters are stricter on geopolitical topics. Smallest context window of the five models at 164K.
Claude Sonnet 4.6: The Community Default
Anthropic released Claude Sonnet 4.6 on February 17, 2026. It has become the most recommended model in the OpenClaw community — not the cheapest, but the most reliable across the three dimensions that matter most for agent work.
The numbers: 79.6% SWE-Bench Verified (1.2 points behind Opus 4.6), 72.5% OSWorld-Verified (within 0.2 points of Opus), and best-in-class office task performance at 1633 Elo on GDPval-AA. In Claude Code testing, 70% of developers preferred Sonnet 4.6 over Sonnet 4.5, and 59% preferred it over the previous flagship Opus 4.5.
The 1M token beta context window is a practical differentiator — you can load entire medium-sized codebases into a single prompt. Haimaker.ai's OpenClaw-specific testing found Sonnet 4.6's JSON schema compliance to be the highest among models in its price range, translating to fewer broken agent loops. Anthropic's safety evaluations show major improvements in prompt injection resistance versus Sonnet 4.5.
On PinchBench — the benchmark specifically designed for OpenClaw agent tasks — Sonnet 4.6 ranks first, above even Opus 4.6, with the top three models separated by less than 1%.
Best for OpenClaw: Production-grade core agent, enterprise deployments requiring security, multi-step autonomous workflows, large codebase analysis.
Watch out for: At \(3/\)15, costs compound quickly during high-frequency agent loops. Reasoning tokens consume context window space and are billed as output. Closed-source means no self-hosting option.
GPT-5.4: The Most Versatile Flagship
OpenAI released GPT-5.4 on March 5, 2026 — the first mainline OpenAI reasoning model with native computer use capabilities. It absorbs GPT-5.3 Codex's coding strengths and adds a 272K standard context window (expandable to 1.05M in the API), five-level configurable reasoning effort, and a tool search mechanism that cuts token costs by 47% in tool-heavy workflows.
Key benchmarks: 57.7% SWE-Bench Pro (slightly above GPT-5.3 Codex), 75.0% OSWorld-Verified (above the 72.4% human baseline), 83.0% GDPval (up from 70.9% for GPT-5.2), and 87.3% on internal investment banking modeling tasks. Zapier called it "the most persistent model to date" for multi-step tool use.
Best for OpenClaw: Complex workflows requiring computer use, cross-file refactoring, enterprise multi-tool agent orchestration.
Watch out for: \(2.50/\)15 base pricing plus reasoning token overhead can exceed expectations. The Pro tier at \(30/\)180 is prohibitively expensive for most use cases. Community feedback on OpenClaw-specific performance is less extensive than Claude's.
The Decision Framework: Which Model for Which User
Personal assistant (email summaries, calendar management, daily automation): Start with DeepSeek V3.2 at under $3/month. Switch to Sonnet 4.6 when quality matters.
Developer (code generation, bug fixing, project automation): MiniMax M2.5 as the workhorse (80.2% SWE-Bench at 1/10th Claude's cost). Sonnet 4.6 for complex multi-file tasks.
Enterprise (production environments, compliance, multi-agent systems): Claude Sonnet 4.6 as the core model (most reliable tool calling, strongest prompt injection resistance). GPT-5.4 when computer use capabilities are needed.
Researcher/Explorer (large-scale information gathering, parallel tasks): Kimi K2.5 Agent Swarm mode for parallel execution. MiniMax M2.5 for fast, cheap code generation.
Multi-Model Routing: The Power Move
OpenClaw's model override feature lets you route different tasks to different models. The community's most battle-tested combination:
| Task Type | Recommended Model | Rationale |
|---|---|---|
| Casual chat & simple queries | DeepSeek V3.2 | Lowest cost, acceptable latency |
| Code generation & fixing | MiniMax M2.5 or Sonnet 4.6 | M2.5 for value; Sonnet for reliability |
| Multi-step autonomous workflows | Claude Sonnet 4.6 | Highest tool-calling reliability |
| Large-scale parallel research | Kimi K2.5 (Swarm mode) | Only model supporting 100 parallel agents |
| Computer use automation | GPT-5.4 or Claude Sonnet 4.6 | GPT-5.4 native support; Sonnet at 72.5% OSWorld |
| Security-sensitive contexts | Claude Sonnet 4.6 | Strongest prompt injection resistance |
Security: The Risk You Can't Ignore
OpenClaw grants AI models broad access to your local system — file read/write, shell execution, browser control, email access. In early 2026, Cisco's security team found third-party skills performing data exfiltration. A computer science student discovered his OpenClaw agent had autonomously created a dating profile on MoltMatch. China restricted government agencies from running OpenClaw in March 2026 citing security concerns.
For model selection, Claude Sonnet 4.6 leads in prompt injection resistance according to Anthropic's system card evaluations. GPT-5.4 also ships with strong safety mechanisms. Open-weight models (M2.5, K2.5, V3.2) offer weaker safety filtering — enterprises should conduct independent security assessments before production deployment.
FAQ
Can OpenClaw only be used with Claude?
No. OpenClaw is model-agnostic and supports Anthropic, OpenAI, Google, and local open-source models via Ollama. Peter Steinberger personally recommends Claude, but the community widely uses DeepSeek and MiniMax as well. Your choice depends on budget, task complexity, and security requirements.
Which of these five models is best for OpenClaw beginners?
Claude Sonnet 4.6 offers the safest starting point — most reliable tool calling, richest community documentation, and strongest prompt injection defense. If budget is the primary constraint, DeepSeek V3.2 costs under $3/month for light use and works well for learning OpenClaw basics.
Is self-hosting open-source models with OpenClaw practical?
It's possible but hardware-intensive. MiniMax M2.5 (230B total parameters, 10B active) requires at least 4x H100 GPUs for reasonable inference speed. Kimi K2.5 (1T parameters, 32B active) needs even more. For most individual users, accessing these models through API aggregation platforms like OpenRouter is more practical.
What should enterprises prioritize when deploying OpenClaw?
Security. OpenClaw's own maintainer warned that if you cannot run a command line, the project is "far too dangerous for you to use safely." Enterprises should choose models with the strongest prompt injection resistance (Claude Sonnet 4.6), run agents in isolated environments, restrict system access permissions, and deploy comprehensive logging.
How does GPT-5.4's computer use capability affect OpenClaw?
GPT-5.4 is OpenAI's first mainline model with a native computer use API — it can see screens, move cursors, click elements, and type text. Combined with OpenClaw's browser control, this enables complex GUI automation workflows. Claude Sonnet 4.6's OSWorld score (72.5%) is close to GPT-5.4's (75.0%), so both handle basic computer use tasks well.

About the Author
Erik (EKC), Digital Strategy Director @ Tenten.co
Over the past twelve months, our team at Tenten has run two concurrent OpenClaw instances alongside Claude MAX, Claude Code, and Kimi K2.5 as part of our AI-native agency transformation. Working with enterprise clients evaluating AI agent frameworks, we've seen a recurring pattern: teams over-optimize for a single "best model" instead of leveraging OpenClaw's real strength — multi-model routing. The most effective starting point for enterprises is building a stable core agent on Claude Sonnet 4.6, gradually introducing lower-cost models for routine tasks, and only then exploring advanced architectures like Agent Swarm.
If your organization is evaluating AI agent deployment strategies or needs model selection and security assessment for specific business workflows, schedule a consultation with the Tenten team.
