LLM Models · FreemiumDisruptively priced open-weight reasoning models (R1) and general-purpose LLMs (V3). Features chain-of-thought reasoning comparable to o1 at a fraction of the cost.
DeepSeek has disrupted the AI landscape with DeepSeek-R1, an open-weight reasoning model that rivals OpenAI's o1-preview performance in coding and mathematics at a fraction of the cost.
Key Models
1. DeepSeek-R1 (Reasoning)
- Chain-of-Thought: Uses advanced reinforcement learning to "think" before answering, excelling at complex logic and coding tasks.
- Performance: Matches top-tier closed models (GPT-4o, Claude 3.5) on benchmarks like AIME and MATH-500.
- Open Weights: Fully open MIT license, allowing local deployment and fine-tuning.
2. DeepSeek-V3 (General Purpose)
- Efficiency: Uses Multi-Head Latent Attention (MLA) and Mixture-of-Experts (MoE) for extreme inference speed.
- Cost: API costs are approximately 90% lower than comparable frontier models ($0.14/1M input tokens).
- Context: Supports up to 128k context window with efficient caching.
Features
- Context Caching: drastically reduces costs for repetitive tasks.
- Local Deployment: Run R1 locally using Ollama or vLLM.
- API Access: Fully compatible OpenAI-format API for easy integration.
Pricing
- API: Extremely low cost (e.g., $0.14/1M input tokens for V3).
- Open Weights: Free to download and use commercially (MIT License).

Rating: 9.6/10 (Best for Google Ecosystem & Long Context)
1. Executive Summary
Gemini 3 is Google's answer to the "reasoning" era of AI. Released in late 2025, it builds upon the massive context capabilities of Gemini 1.5 but introduces a new "Deep Think" mode similar to OpenAI's o1/o3 series.
Gemini 3 is natively multimodal from the ground up, designed to process video, audio, and code streams of virtually infinite length. Its defining feature remains its Long Context Window—now extended to 10 Million tokens in the Pro version. This allows developers to dump entire repositories, hour-long videos, or massive legal archives into a single prompt.
In 2026, Gemini 3 is deeply integrated into the Firebase and Google Cloud ecosystems. Tools like Firebase Studio (Project IDX) use Gemini 3 to offer "full-stack awareness," understanding not just your code but your deployment config, database schema, and analytics data simultaneously.
Key Highlights (2026 Update)
- 10M Token Context: The largest in the industry. Can hold thousands of code files or hours of video.
- Deep Think Mode: A slow-thinking mode for complex architecture and math problems.
- Native Multimodality: Exceptional performance on video understanding (e.g., "Find the moment in this 2-hour video where the user clicks the 'Buy' button").
- Code Execution: Can write and execute Python code in a sandboxed environment to verify its own answers.
- Grounding: Integrated with Google Search to provide real-time, fact-checked information.
2. Core Features & Capabilities
2.1 Infinite Context
The 10 million token window changes how developers approach problems.
- Legacy Migration: You can upload the entire source code of a 20-year-old mainframe application. Gemini 3 can analyze the global structure, call graphs, and dependencies to plan a migration to the cloud.
- Video QA: Upload a screen recording of a bug. Gemini 3 watches it, correlates it with the logs you paste, and identifies the root cause.
2.2 Deep Think Reasoning
Gemini 3 introduces "System 2" thinking. When asked a complex question, it pauses to "think" (generating hidden chain-of-thought tokens) before answering.
- Use Case: "Design a sharded database schema for a global chat app handling 1B users."
- Result: It produces a highly detailed, academically rigorous design document, considering edge cases that faster models miss.
2.3 Google Ecosystem Synergy
- Android Studio: Gemini 3 is embedded in Android Studio, offering context-aware help for Jetpack Compose and Kotlin.
- Colab Enterprise: It serves as a data science partner, writing and debugging Python notebooks in real-time.
3. Performance & Benchmarks (2026 Data)
Gemini 3 excels in long-context and multimodal tasks.
| Benchmark | Gemini 3 Ultra | GPT-4o | Notes |
|---|---|---|---|
| MMMU (Multimodal) | 62.4% | 61.8% | Slight edge in complex multimodal reasoning. |
| Needle In A Haystack | 100% | 100% | Perfect recall even at 10M tokens. |
| HumanEval | 91.5% | 90.2% | Very strong coding performance. |
| Video Understanding | SOTA | - | Unrivaled in analyzing long video content. |
