## Overview

Choose Gemini when you want Google's multimodal, voice, and image models and a low per-token price on Flash tiers; choose Claude for long-horizon agent loops and for access through several clouds. Prices below are per million input and output tokens, checked on 2026-10-01 against each vendor's documentation. For the OpenAI comparison see [[comparisons/claude-vs-gpt]].

## Compare

| Dimension | Gemini | Claude |
| --- | --- | --- |
| Top model | Gemini 3.1 Pro, `gemini-3.1-pro-preview` (preview): $2 / $12, rising to $4 / $18 for prompts above 200K tokens | Claude Fable 5.1, `claude-fable-5-1`: $10 / $50, 1M context |
| Mid and fast tiers | Gemini 3.8 Flash, `gemini-3.8-flash` (stable): $0.75 / $3.75 through 2026-12-31, then $1.50 / $7.50 from 2027-01-01 | Opus 5.5 $4 / $20; Sonnet 5.5 $2 / $10; both 1M context |
| Cheapest | Gemini 3.1 Flash-Lite: $0.25 / $1.50; 2.5 Flash-Lite: $0.10 / $0.40 | Haiku 4.5, `claude-haiku-4-5`: $1 / $5, 200K context |
| Media models | Image generation and editing (Nano Banana 2), Live voice, TTS, transcription, music, and video models | No image, audio, or video generation |
| Batch and caching | 50 percent batch discount; cached input billed at a reduced rate | 50 percent batch discount; cache reads at 10 percent of input (5 percent on Opus 5.5, 2.5 percent on Fable 5.1) |
| Clouds | Gemini API and Google Cloud | Claude API, Amazon Bedrock, Google Cloud Vertex AI, Microsoft Foundry, Claude Platform on AWS |

## Pick Gemini when

Pick Gemini for media-rich and cost-sensitive workloads.

- Products that need generated images, voice agents, speech-to-text, or video in one vendor.
- High-volume, latency-tolerant work on Flash or Flash-Lite tiers, where list price dominates; compare cost per completed task.
- Prototyping on the free tier, or stacks centered on Google Cloud.
- Plan for preview status: `gemini-3.1-pro-preview` is a preview model, and Flash pricing doubles on 2027-01-01.

## Pick Claude when

Pick Claude for agent reliability and deployment flexibility.

- Long-running, tool-using agents and coding work; start on Opus 5.5 and escalate to Fable 5.1 when evals at higher effort fall short.
- Procurement through Bedrock, Vertex AI, or Foundry, or US-only inference on the Claude API with `inference_geo` (1.1x price).
- Strict tool schemas and structured outputs; see [[ai-agents/structured-output]].

## Run both

Put a router in front, keep prompts per provider, and run a shared eval suite before moving traffic ([[ai-agents/evaluation]]). Parameters differ across models, so do not carry sampling settings between providers; see [[comparisons/claude-vs-gpt]] for the Claude constraints. Track spend per task type ([[ai-agents/cost-control]]).
