## 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 AI

Illusion Diffusion AI is a web app built around a single, focused idea: hiding a recognisable shape inside another picture so the eye only resolves it from a certain distance. Users upload a reference image — a face, a product shot, a logo, or even a favourite quote set as text — and then supply a text prompt describing the scene that should camouflage it. The generator returns artwork where the original silhouette is embedded in the new composition.

Under the hood the tool chains a known diffusion pipeline. ControlNet reads the uploaded image and extracts its contours with a Canny edge detector to build a structural control map; OpenPose then identifies human keypoints such as hands, legs and head position when a person is present. Those conditions steer Stable Diffusion, which paints a brand-new picture that still respects the original outline. The site advertises fast generation with no long queue when credits are used.

Access is pay-as-you-go. Visitors can try the playground and browse a public gallery of user creations, while output at full quality is unlocked by buying image credits. The company positions itself around privacy (uploads used only for internal processing) and states that payments are handled entirely by Stripe.

**Pricing & Plans:** Credit-based one-time purchases rather than a subscription: three tiers are published — a Starter pack of 40 image credits, a Basic pack of 100 credits, and an Advanced pack of 500 credits, each with a discounted promotional price and a stated validity window. One credit equals one generated artwork. A free trial is offered without a credit card.

- **Photo-to-illusion generation:** Upload any picture — portrait, product, pet — and the model rebuilds it as a hidden-shape optical illusion image.
- **ControlNet + OpenPose pipeline:** Edges are extracted with a Canny detector and human keypoints mapped with OpenPose so the illusion keeps the subject's real contours.
- **Text and logo camouflage:** Quotes, slogans and brand marks can be used as the hidden layer, with the AI painting a scene around those letterforms.
- **Credit packs, no subscription:** Buy 40, 100 or 500 credits in one payment; each credit produces one high-quality image with no watermark.
- **Privacy-minded processing:** Uploaded photos are described as used solely for internal AI processing and never shared with third parties.

**Strengths:** Very specific niche — the illusion effect is strong and visually distinctive; Transparent credit pricing that you can buy once instead of subscribing; Public gallery and free playground let you judge quality before paying; Payments handled by Stripe, with a clear no-third-party-sharing privacy statement

**Limitations:** No refunds are offered once credits are consumed; Credits expire within one or two months depending on the pack; Only one image size/quality is described, with no visible batch or API option on the landing page
