## 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

## Illusion Diffusion Web

Illusion Diffusion Web is a focused, single-purpose creative tool: it takes an image you already have and hides it inside an optical illusion. You bring a photo or select one of the built-in patterns, write a prompt describing the effect you want, and set the illusion strength slider to decide how aggressively the AI reinterprets the source. The output keeps the readable shape of the original while filling it with the texture and logic of the illusion, which is what gives these images their distinctive double-take quality.

Under the hood it uses Stable Diffusion for image synthesis and ControlNet for prompt-driven control over style and structure. Beyond the prompt and strength controls, advanced options expose the guidance scale, ControlNet parameters, upscaling strength and a seed value, so you can lock in a result you like and reproduce it, or nudge individual variables to explore variations. Patterns can be applied in addition to text prompts, which opens up a wide range of styles from classic contour-line illusions to dense typographic effects.

Pricing is credit-based rather than subscription-based: you buy a one-off pack of image credits and spend one credit per artwork. Every pack advertises fast generation, high-quality output and no watermark, and downloads are yours to keep or share on social platforms. It is a straightforward option for people who want a specific visual gag or art effect without learning a full diffusion pipeline.

**Pricing & Plans:** One-time credit packs with no subscription: 500 image credits for $7.9, 1,000 credits for $9.9 (most popular), or 5,000 credits for $29.9. One credit equals one AI artwork, and paid images come without a watermark.

- **Photo-to-illusion transformation:** Upload any photo or choose a pattern and let AI algorithms rebuild it as an optical illusion, from subtle texture shifts to dramatic surrealist effects.
- **Adjustable illusion strength:** A dedicated slider controls how intensely the transformation is applied, so you can keep the original photo recognisable or push it into pure abstraction.
- **Advanced generation controls:** Expose guidance scale, ControlNet settings, upscaling strength and seed values for precise, repeatable results.
- **Pattern-based illusions:** Apply built-in patterns in addition to your text prompt to create classic contour, typographic and other illusion styles.
- **Credit packs with downloadable output:** Buy credits as needed at roughly a cent per image, generate without watermarks, and download or share the results.

**Strengths:** Purpose-built for one effect it does well: optical illusions and surreal photo transformations.; Granular control through illusion strength, guidance scale, ControlNet parameters and seeds.; Pay-as-you-go credit packs avoid an ongoing subscription commitment.; Generated images are watermark-free and downloadable, so they are immediately usable.

**Limitations:** Credit packs are one-time purchases, so heavy users must buy repeatedly rather than benefit from a monthly plan.; It relies on Stable Diffusion and ControlNet, meaning results still need prompt iteration to look right.; The feature set is narrow by design: this is an illusion tool, not a general-purpose image editor.
