Gemini 3.1 Pro vs LocIn AI: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Gemini 3.1 Pro and LocIn AI — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Gemini 3.1 Pro
Google (Google Research / Google DeepMind)
High-capacity multimodal model optimized for complex reasoning and very long-context tasks when simple answers aren’t enough.
Key features
- 1M+ Token Context Window: Supports extremely long contexts (reported 1,048,576+ token capacity) enabling analysis, summarization, and reasoning over very large documents, codebases, or multi-file datasets.
- Enhanced Multi-step Reasoning: Improved capabilities for complex, multi-step problem solving and chain-of-thought style reasoning for planning, debugging, and research tasks.
- Multimodal Input Support: Accepts text, images, PDFs and video inputs, letting users combine modalities in a single session for richer understanding and cross-modal retrieval.
- API Accessibility and Model ID: Available through the Gemini API with the model identifier gemini-3.1-pro, enabling programmatic integration into applications and developer tooling (CLI, Vertex AI, Google Cloud).
- Large Output Support: Capable of producing very long outputs suitable for detailed reports, long-form generation, and exhaustive code or document revisions (community config cites output windows up to 65,536 tokens).
- Phased Rollout & Access Controls: Released via a staged rollout (initially to AI Ultra / AI Ultra for Business subscribers and via API keys with appropriate permissions) with session and quota behaviors managed per Google account or API key.
- Very large context window: 1M+ tokens (e.g., 1,048,576 context in provider configs)
- Multi-modal input support: text, image, PDF, video
- Text output modality (configurable large output limit noted in configs: 65536)
- Available via Gemini API and Gemini CLI (gemini tool)
- Model IDs: gemini-3.1-pro and gemini-3.1-pro-preview
- Enhanced reasoning and complex problem-solving capabilities compared with earlier Gemini releases
- Phased rollout with API-key immediate availability (if permissions enabled) and staged Google Login rollout (AI Ultra tiers prioritized)
- Integrates with Google platforms such as AI Studio and Vertex AI (as referenced in rollout guidance)
Best for
- Long-form Research Synthesis: Ingest and synthesize entire research papers, corpora, or legal collections (multi-file PDFs and documents) and produce structured summaries, literature reviews, or annotated bibliographies across 1M+ token contexts.
- Large-Scale Codebase Analysis: Perform architectural analysis, cross-file refactoring suggestions, and multi-step debugging for million-line codebases by maintaining context across many files and commits.
- Enterprise Knowledge Assistant: Index and query company knowledge (handbooks, contracts, PDFs, recorded meetings) to answer complex policy and compliance questions requiring multi-document reasoning.
- Multimodal Media Intelligence: Analyze and correlate video transcripts, images, and associated documents to produce investigative reports, scene summaries, or multimedia content plans.
- Strategic Planning and Simulation: Drive multi-step scenario planning, decision trees, and detailed stepwise recommendations for product, legal, or research strategies requiring deep reasoning over prolonged context.
- Long-form document understanding and summarization using 1M+ token context
- Multi-modal analysis combining text with images, PDFs, or video
- Complex reasoning and multi-step problem solving (research, technical analysis, legal/medical summarization)
- Large-codebase generation, review and debugging where sustained context is required
- Interactive agents and assistants that must maintain very large conversational state
LocIn AI
