## 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

## eFiling.us

Court eFiling is repetitive, form-heavy work. A paralegal or attorney often re-enters the same information — case captions, party names, index numbers, document types — into a court portal that has already been typed in the pleading itself. eFiling.us targets exactly that duplication. It is a Chrome extension that reads the pleading with an AI model, extracts the fields the filing system needs, and then drives the court portal through a set of automation components.

The product is distributed through the Chrome Web Store and is published by eFiling.us Inc, a New York based company. It is currently scoped to the New York State Courts E-Filing System (NYSCEF), the state's electronic filing portal, and the extension runs on top of that site as an overlay rather than as a separate web app. Because the extension needs to act inside the court portal and read sensitive documents, it requests access to personally identifiable information, payment information, and authentication data, and the developer publishes a privacy disclosure covering that use.

The extension is offered with in-app purchases rather than a standing free plan, which fits a professional legal user who files regularly and values time over a per-seat consumer price. It is a young product with a small install base and a single rating, so it is best evaluated with a hands-on trial on real filings before being added to a firm's standard workflow.

**Pricing & Plans:** Offered as an in-app purchase Chrome extension rather than a free tool, with pricing handled inside the product; no public self-serve price list, and the vendor invites direct contact for custom arrangements. It has been categorised as contact-for-pricing.

- **AI pleading extraction:** An AI model reads uploaded pleadings and pulls out the case details, parties, and metadata needed to populate a court filing.
- **One-click eFiling automation:** Pre-built automation components carry the extracted data into the court eFiling portal so routine filings can be completed in seconds.
- **NYSCEF-ready:** Built for the New York State Courts E-Filing System (NYSCEF), matching that portal's forms, fields, and workflow.
- **Browser-native workflow:** Runs as a Chrome extension directly on the court eFiling site, so no separate dashboard or file transfer is required.
- **Complex case support:** Handles complex case documents as well as standard pleadings, aiming to reduce manual re-typing and form filling.

**Strengths:** Automates the repetitive data entry that surrounds court eFiling; AI extraction is tuned to pleadings rather than generic documents; Purpose-built for the NYSCEF portal instead of a generic form filler; Runs inside the browser on the court site, so there is no migration

**Limitations:** Currently limited to the New York State Courts E-Filing System (NYSCEF); Requires in-app purchases; no open free tier for heavy use; Very small user base, so community support and reviews are limited; Extension access to court and authentication data demands trust in a young vendor
