Gemini 4 vs GPT-5.5 vs Claude Opus 4.7 (May 2026)
Gemini 4 vs GPT-5.5 vs Claude Opus 4.7 (May 2026)
Three frontier-class models, three different strengths. Gemini 4 just launched at Google I/O on May 19, 2026. GPT-5.5 Instant is now the ChatGPT default. Claude Opus 4.7 is the SWE-bench leader. Here’s how they actually compare today.

What each model is for
Gemini 4 — the multimodal long-context model
Google’s May 19 release. Best when:
- You need 10M-token context (whole-codebase, whole-book, whole-quarter of meeting transcripts).
- You’re building on Android, Google Cloud, or Vertex AI.
- The job needs video, audio, or spatial reasoning as a first-class modality.
- You want the model powering Gemini Intelligence on Android and AI Mode in Google Search.
GPT-5.5 — the conversational default
The new ChatGPT default (GPT-5.5 Instant) is tuned for low latency, low hallucination in high-stakes domains (medicine, law, finance), and personalised context across previous chats / files. Best when:
- You want the mainstream consumer experience (ChatGPT distribution).
- You’re on Azure / Microsoft 365 Copilot.
- You need GPT Realtime 2 for live voice.
- You’re building with OpenAI Workspace agents or Codex.
Claude Opus 4.7 — the autonomous coder
The agentic coding model. Best when:
- You’re building autonomous coding agents (Claude Code, terminal workflows).
- You need the highest SWE-bench score in May 2026.
- You’re on AWS Bedrock or running Claude Managed Agents.
- You want Outcomes (rubric eval) and Dreams (memory) wired in.
Head-to-head by workload
Long-context (>1M tokens)
Winner: Gemini 4. It’s the only one with a real 10M-token practical window.
Use cases: whole-codebase refactors, multi-quarter financial filings, year of meeting transcripts, multi-book research synthesis.
Autonomous coding
Winner: Claude Opus 4.7. Highest SWE-bench, Claude Code’s default model, best at multi-file project management.
Runner-up: GPT-5.5 via Codex. Gemini 4 is competitive in Android Studio specifically.
Conversational chat / consumer
Winner: GPT-5.5 Instant. Default ChatGPT model, lowest latency among frontier-class, strong on grounded answers.
Runner-up: Gemini 4 (in the Gemini app), then Claude (general chat).
Multimodal generation
Winner: Gemini 4. Native video, audio, and spatial generation. Used by Android XR glasses for real-time visual context.
Runner-up: GPT-5.5 + GPT Realtime 2 for voice. Claude is text-and-image-input only.
Agentic workflows
Tie depending on stack:
- On Google → Gemini 4 + Vertex agents + Gemini Enterprise.
- On Anthropic → Claude Opus 4.7 + Managed Agents + Multi-agent Orchestration (up to 20 specialists).
- On Microsoft → GPT-5.5 + Copilot Studio + Workspace agents.
Voice / real-time
Winner: GPT-5.5 with GPT Realtime 2 / Realtime Translate / Realtime Whisper. OpenAI’s voice stack is the most production-ready in May 2026.
Gemini 4 + Gemini Live is a strong runner-up. Claude is voice-input via integrations, not a first-class real-time model.
Distribution and where each model lives
| Surface | Default model |
|---|---|
| ChatGPT | GPT-5.5 Instant |
| Claude.ai | Claude Sonnet 4.5 / Opus 4.7 |
| Gemini app | Gemini 4 |
| Google Search AI Mode | Gemini 4 |
| GitHub Copilot | GPT-5.5 (Microsoft Copilot+ stack) |
| Claude Code | Opus 4.7 |
| Cursor | User-selectable; Opus 4.7 and GPT-5.5 are common |
| Android Studio | Gemini 4 |
| Microsoft 365 Copilot | GPT-5.5 + Microsoft custom |
| Vertex AI | Gemini 4 + Claude (Anthropic on Vertex) + others |
| AWS Bedrock | Claude Opus 4.7 + Llama 4 + Mistral + others |
Pricing posture (May 2026)
Pricing changes monthly — verify on each provider’s pricing page before committing.
- Gemini 4 — premium tiers via Vertex AI + Gemini Advanced consumer subscription. Free tier in the Gemini app gives basic 4 access.
- GPT-5.5 — included in ChatGPT Plus / Pro / Enterprise; API pricing tiered.
- Claude Opus 4.7 — Claude Pro / Max ($100-$200/mo) for heavy use; API pricing premium.

TL;DR
No single model wins everything in May 2026. Gemini 4 is the long-context multimodal king. Claude Opus 4.7 is the autonomous coder. GPT-5.5 Instant is the conversational default. Pick by workload and cloud, not by brand — and assume the answer changes again at OpenAI DevDay.
