## DeepSeek

DeepSeek (Hangzhou DeepSeek Artificial Intelligence Co., Ltd.) is a frontier AI research organization that disrupted the global LLM market by pairing open-weight transparency with breakthrough Mixture-of-Experts (MoE) and reinforcement-learning reasoning efficiency. Following the landmark releases of DeepSeek-V3 and the peer-reviewed DeepSeek-R1 reasoning model, DeepSeek introduced the DeepSeek-V4 generation in 2026—featuring a hybrid attention architecture and a native 1-million-token context window across DeepSeek-V4-Pro (1.6T total parameters, 49B active per token) and DeepSeek-V4.1-Flash (284B total parameters, 13B active per token).

Users can interact with DeepSeek in three ways: completely free through the consumer web portal (chat.deepseek.com) and mobile apps with one-click toggles for deep thinking and live web search; via DeepSeek's hosted, OpenAI-compatible developer API; or by self-hosting DeepSeek's open-weight checkpoints (including V3, R1, Prover-V2, and distilled Qwen/Llama variants) on private infrastructure. The models excel at competitive mathematics, algorithm design, repository-level software engineering, and structured data extraction, with automatic context caching on the API that slashes repeated prompt costs by over 95%.

In late 2026, DeepSeek remains the price-performance benchmark for developers and automation workflows. While the consumer chat interface remains free without a mandatory $20/month subscription tier, the developer API transitioned in late 2026 to two primary endpoints—`deepseek-flash` and `deepseek-v4-pro`—with time-of-day pricing. Off-peak API calls cost just $0.15 per million input tokens ($0.003 on cache hits) and $0.60 per million output tokens on Flash, and $0.66 input / $1.98 output on V4-Pro, making it a fraction of the cost of comparable Western frontier models.

**Pricing & Plans:** Free web and mobile chat app at chat.deepseek.com; pay-as-you-go OpenAI-compatible API with off-peak rates at $0.15/1M input ($0.003 cache hit) and $0.60/1M output for deepseek-flash (V4.1-Flash), and $0.66/1M input ($0.022 cache hit) and $1.98/1M output for deepseek-v4-pro (peak weekday UTC hours bill at 2x).

- **DeepSeek-V4 Hybrid Attention & 1M Context:** Leverages a sparse Mixture-of-Experts architecture (49B active parameters out of 1.6T on V4-Pro) to process up to 1 million tokens with minimal latency and memory overhead.
- **Transparent Chain-of-Thought Reasoning:** Pioneered by DeepSeek-R1 and integrated into V3.2 and V4 thinking modes, exposing step-by-step self-verification for complex math, logic, and code debugging.
- **Automatic Context Caching & Off-Peak API Pricing:** Drops input token costs to $0.003/1M on Flash and $0.022/1M on V4-Pro for cache hits, with 50% lower rates during off-peak UTC hours.
- **Free Consumer Web & Mobile Assistant:** Provides free access at chat.deepseek.com and on iOS/Android with document uploads, reasoning mode, and web search without paywalling core models.
- **Open-Weight Ecosystem & Self-Hosting Freedom:** Offers open weights for DeepSeek-V3, R1, Distill variants, and Prover models on Hugging Face and GitHub so enterprises can deploy within air-gapped environments.

**Strengths:** Completely free consumer web and mobile app with deep reasoning and web search included; Ultra-low API token rates ($0.15/$0.60 on Flash, $0.66/$1.98 on V4-Pro off-peak) with up to 98% savings on cached inputs; Drop-in OpenAI API compatibility makes switching or routing between models effortless; Strong open-weight lineage allows teams to self-host or fine-tune models without vendor lock-in

**Limitations:** Hosted API and web app store data on servers in China, prompting compliance restrictions for some Western enterprises and government agencies; Peak-hour API pricing (01:00–04:00 and 06:00–10:00 UTC on weekdays) doubles per-token costs compared to off-peak rates; Lacks native voice mode, video generation, and productivity suite integrations offered by ChatGPT and Google Gemini

## FieldDay · Real-World AI

FieldDay turns the iPhone into a self-contained applied-ML environment. Instead of sending photos to a cloud service or hiring a data scientist, you define categories for the objects, gestures, or scenes you want the camera to recognize, then record samples from different angles and lighting conditions. FieldDay trains a compact classifier on-device, lets you test it live in the camera view, and gives you a simple correction loop: every time the model misreads something, you mark the right answer and it learns from that example. The whole loop is designed to take minutes rather than weeks, and everything happens in a friendly, visual interface that requires no programming.

Once a model behaves the way you want, FieldDay offers two paths forward. You can keep it in the app and attach an action: connect HomeKit devices or scenes to specific categories so that simply pointing the camera at a room, lamp, fan, or outlet surfaces the right smart-home controls. Or you can export the model to platforms you already use, including Siri Shortcuts for image-based predictions, Snap Lens Studio, and Xcode for deeper integration into your own projects and workflows.

The app is aimed at a broad audience — hobbyists experimenting with computer vision, makers building camera-driven gadgets, teachers creating interactive lessons, and product teams prototyping retail or accessibility experiences. FieldDay was developed by New Material, Inc. (with ties to New Material Studio Ltd in the UK) and is published on the Apple App Store for iPhone running iOS 16 or later. It is a genuine first-party app, not an unofficial or third-party clone of a larger brand.

**Pricing & Plans:** Free to download and — per the latest App Store update — free to use: version 1.2.0 removed subscriptions and in-app purchases so all features are available at no cost. Earlier releases experimented with a FieldDay Pro subscription and paid training credits, so ignore old pricing references you may find online.

- **On-device model training:** Collect a custom image dataset with your iPhone camera and train a vision classifier right on the phone, with no cloud round-trip and no code.
- **Correction-based fine-tuning:** Every misclassification can be corrected in place, letting the model improve iteratively as you keep using it in the real world.
- **HomeKit actions:** Assign HomeKit lights, outlets, fans, or scenes to specific categories so that recognizing an object in the camera view instantly brings up the matching controls.
- **Model export:** Take your trained classifier beyond FieldDay and reuse it in Siri Shortcuts, Snap Lens Studio, Xcode, and other popular formats and tools.
- **Real-time camera testing:** Test predictions live through the camera while you are still training, so you can see exactly when a model is good enough to ship.

**Strengths:** Genuinely no-code: the entire pipeline from data collection to a working classifier happens in one visual iPhone app.; Fast iteration loop — collection, training, live testing, and correction are all in the same place, so experiments take minutes.; Useful escape hatches: HomeKit actions and export options (Shortcuts, Lens Studio, Xcode) keep models from being locked inside the app.; Now completely free after the 1.2.0 update removed subscriptions and in-app purchases.

**Limitations:** iPhone-only (iOS 16+) — there is no Android or web version.; Requires an Apple device for the smart-home and Shortcuts integrations to be useful at all.; Accuracy depends heavily on the quality and variety of the training data you collect yourself.
