## 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

## PEC Plus

PEC Plus is a lightweight Chrome extension built for health professionals who use PEC, the electronic health record of Brazil's E-SUS Atenção Básica (primary health care) system. Rather than replacing the record, it plugs into it: as a doctor or nurse works through a consultation, the extension reads what has been selected in the SOAP "Avaliação" (assessment) field and surfaces timely, context-specific guidance right where the decision is being made.

The extension focuses on a few high-value moments. For compulsory-notification diseases and conditions, selecting a diagnosis triggers a reminder to complete the SINAN form, with links to download the form and to the Ministry of Health's official list of notifiable conditions under Portaria GM/MS No. 217. For longitudinal monitoring, it suggests validated scores tied to the selected problem — GAD-7 for anxiety-related issues, PHQ-9 for depressive disorders and a Mini-Mental State Examination form for dementia syndromes. And in the "Planos" field, requesting MRPA or a glycemic diary/map produces a printable PDF template.

The tool is published on the Chrome Web Store by developer Heric Santos, is offered free of charge, and runs only in Brazilian Portuguese. It has a small user base so far. Importantly, it is an assistive aid, not an autonomous diagnosis system, and in line with LGPD it neither saves nor transmits patient information, keeping data handling on the clinician's own session.

**Pricing & Plans:** Free. PEC Plus is a free Chrome extension with no published paid tiers.

- **SINAN notification reminders:** When you select a notifiable disease in the SOAP assessment field, PEC Plus prompts you to complete the SINAN form and links to the form and the Ministry of Health's official list.
- **Score suggestions:** It suggests validated instruments matched to the problem, such as GAD-7 for anxiety, PHQ-9 for depression and the Mini-Mental State Examination for dementia syndromes.
- **MRPA and glycemic diary templates:** Requesting MRPA or a glycemic diary in the 'Planos' field produces a ready-to-print PDF template.
- **In-workflow guidance:** Guidance appears directly inside the PEC during the consultation, so it fits the existing SOAP workflow instead of replacing it.
- **LGPD-compliant by design:** The extension does not save or transmit patient information, aligning with Brazil's LGPD data-protection law.

**Strengths:** Sits inside the existing PEC E-SUS workflow rather than replacing it; Surfaces SINAN notification reminders at the right moment; Suggests validated scores like GAD-7, PHQ-9 and MMSE; Generates printable MRPA and glycemic diary templates

**Limitations:** Portuguese-only and no ratings yet on the Chrome Web Store; Requires existing access to the PEC E-SUS AB system to be useful; Last updated in 2023, so it may lag behind PEC changes; Suggestion-based only; it is not a standalone diagnosis tool
