## 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

## teste.ai

Teste.ai is a Brazilian platform that packages a toolbox of AI-based testing utilities for software quality professionals. From a single requirement or a passage of documentation, it generates complete test plans with scenarios, test cases and step-by-step scripts, so testers spend less time writing specifications and more time on higher-value analysis. It also generates structured test data on demand and includes a generator that writes SQL queries for pulling specific data from a database based on a natural-language description.

The platform is designed to be test-type agnostic: functional, API, usability, security and performance testing are all supported, and you can apply techniques such as boundary value analysis from within the same workspace. Under the hood it uses OpenAI language models combined with prompts crafted specifically for quality work, and the vendor states that your inputs are not used for model training and that queries are stored in a private history you can delete.

Access requires signing up and choosing a plan, with a free starting tier that includes test case and step-by-step generators and paid Pro plans billed monthly or annually. The product is built by Paiva Software Engineering in São Paulo, Brazil, and content is primarily presented in Portuguese.

**Pricing & Plans:** Freemium with a free starting plan that includes core generators such as the test case and step-by-step generators, plus paid Pro subscription plans available monthly or annually and cancellable at any time.

- **Test case, scenario and step generator:** Create complete test plans with scenarios, test cases and step-by-step scripts from just a requirement or a snippet of your documentation.
- **Test data (massa) generation:** Generate structured test data on demand in the quantity and shape you need, without manual spreadsheet work.
- **Natural-language SQL query builder:** Describe what you need in plain language and Teste.ai writes the corresponding SQL query for locating specific test data in a database.
- **Support for many test types:** Coverage extends to API, functional, usability, security and performance testing, all documented from one place.
- **Quality-tuned AI prompts:** Uses OpenAI language models with prompts purpose-built for software quality, and logs your queries in a private history.

**Strengths:** Turns a single requirement into full test plans and cases; Purpose-built prompts remove the need to craft your own; Generates test data and natural-language SQL queries; Covers functional, API, security and performance testing

**Limitations:** Interface and content are predominantly in Portuguese, which may slow non-Portuguese speakers; Requires account signup and a plan to access the full toolkit; Output quality depends on the clarity of your requirements or documentation; No native offline mode; it is a cloud-based platform
