GPT-5 vs Claude vs Gemini in OpenClaw:
Which Model Wins? (March 2026)
OpenClaw v2026.3.7-beta added explicit support for GPT-5.4 and Gemini 3.1 Flash with automatic model failover. We benchmarked all three on the task types OpenClaw users run most. Here's what we found.
Quick verdict
| GPT-5.4 | Claude Sonnet 4.6 | Gemini 2.5 Pro | |
|---|---|---|---|
| SWE-Bench score | 74.9% | 72.7% | 63.8% |
| Context window | 1M tokens | 200K tokens | 2M tokens |
| Input cost / 1M | $15 | $3 | $1.25 |
| Output cost / 1M | $60 | $15 | $10 |
| Best for | Max reasoning | Best value | Long docs |
| OpenClaw support | v2026.3.7+ | All versions | v2026.1+ |
Task-by-task breakdown
Email triage & drafting — Claude Sonnet 4.6
Best instruction-following, writes in your voice with consistent tone. GPT-5 is overkill for this task category and costs 5x more. Gemini is adequate but produces less consistent brand voice across threads.
Coding & dev tasks — GPT-5.4
GPT-5.4 tops SWE-Bench at 74.9%. For complex refactoring or architectural work, GPT-5 edges Claude by a meaningful margin. That said, for everyday PRs and code review, Claude Sonnet is 5x cheaper with near-identical results.
Research & long documents — Gemini 2.5 Pro
Gemini 2.5 Pro's 2M token context window handles entire books, legal documents, or large datasets in one pass. For research tasks where cost matters, Gemini wins decisively — $1.25/M input vs $15 for GPT-5.
Autonomous multi-step agents — Claude Sonnet 4.6
Best tool-calling consistency and lowest hallucination rate on long agentic chains. GPT-5 is strong but costs 5x more for equivalent agent reliability. For production agents running 24/7, Claude Sonnet is the most economical choice with the best error profile.
OpenClaw Auto-Failover: Use Multiple Models Together
OpenClaw v2026.3.7-beta introduced automatic model failover. Configure a primary model (e.g., Claude Sonnet 4.6) and a fallback chain (e.g., Gemini 2.5 Flash). If the primary provider is rate-limited, over quota, or unavailable, OpenClaw silently retries on the fallback — no task failure, no manual intervention.

All three provider API keys managed in one place — Anthropic, OpenAI, Google.
Cost comparison: 100 tasks/day for 30 days
Assuming ~5,000 tokens per task (mixed input/output).
| Model | Volume | Monthly cost estimate |
|---|---|---|
| GPT-5.4 | 100 × ~5K tokens | $390–$975/mo |
| Claude Sonnet 4.6 | 100 × ~5K tokens | $78–$195/mo |
| Gemini 2.5 Flash | 100 × ~5K tokens | $12–$30/mo |
| Claude Haiku 4.5 | 100 × ~5K tokens | $7–$18/mo |
GetClaw Hosting adds a flat monthly fee for your dedicated gateway — no per-token markup on your API calls.
Frequently asked questions
- Which AI model is best for OpenClaw in 2026?
- Claude Sonnet 4.6 is the best all-round choice — used by 55% of OpenClaw users, 72.7% SWE-Bench, and 5x cheaper than GPT-5 for equivalent results on most tasks. Use GPT-5.4 for maximum reasoning depth, and Gemini 2.5 Pro when you need a 2M token context window for large documents.
- Does OpenClaw support GPT-5?
- Yes. OpenClaw v2026.3.7-beta added explicit support for GPT-5.4 via the OpenAI provider. Earlier versions support GPT-4o and GPT-4.1. You need an OpenAI API key with GPT-5.4 access. GetClaw Hosting configures multi-provider support so you can run GPT-5, Claude, and Gemini simultaneously with automatic failover.
- Can OpenClaw switch between models automatically?
- Yes. OpenClaw v2026.3.7-beta introduced automatic model failover and retry. You configure a primary model and fallback chain. If the primary provider is rate-limited or unavailable, OpenClaw switches to the fallback automatically. GetClaw Hosting manages credentials for all three major providers (Anthropic, OpenAI, Google) out of the box.
