## 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

## Stable Diffusion API

Stable Diffusion API gives developers a single HTTP endpoint for the whole Stable Diffusion family and a long list of community checkpoints. Instead of provisioning GPUs, installing PyTorch, and keeping model weights in sync, you send a POST request with a prompt, model id and parameters, and receive generated images plus a track id you can poll or receive via webhook. The catalog the site advertises covers SD 1.5, SDXL, Stable Diffusion 3, FLUX.1 dev/Schnell, FLUX.2 dev, Qwen Image, Z-Image Turbo, video models such as Wan 2.2 and LTX Video, and dedicated families like Realistic Vision, Juggernaut XL, Pony Diffusion, DreamShaper and Illustrious XL.

Beyond plain text-to-image, the API exposes image-to-image, inpainting, upscaling, background removal, ControlNet conditioning, LoRA usage and Dreambooth-style model fine-tuning, so a single integration can cover asset generation, product mockups, advertising variants and interior or fashion visuals. Official code samples for cURL, Python and Node are published for each model page, which shortens the time from signup to a first working request.

The platform is now presented as part of ModelsLab: accounts, API keys and billing live in the ModelsLab dashboard, and the site states that API requests are processed at scale with a 99.99% uptime target. Pricing is transparent and outlined on the site, with plans starting at $21 per month and an unlimited open-source tier for high-volume workloads.

**Pricing & Plans:** Paid plans billed through ModelsLab: Basic $21/month (3,250 API calls, 5 parallel generations), Standard $47/month (10,000 calls, 10 parallel generations), and Open Source Unlimited $149/month or $1,500/year (unlimited generations on self-hosted open-source models, 15 parallel generations). Third-party and closed models are billed separately; Enterprise offers dedicated GPUs and custom SLAs. Creating an account is free, but API access requires a paid plan.

- **Unified REST endpoint:** One POST endpoint handles text-to-image, image-to-image and editing jobs across SD 1.5, SDXL, Flux, ControlNet and LoRA models, with cURL, Python and Node samples for each model.
- **Large community model catalog:** Thousands of community checkpoints and LoRAs, including anime, photorealistic and stylized families, are browsable with their parameters and sample code.
- **Async jobs and webhooks:** Requests return a job id or track id so long-running generations can be polled or pushed to your own webhook endpoint instead of blocking the client.
- **Fine-tuning and training:** Dreambooth-style endpoints let you train custom concepts and styles on your own images, then reuse the resulting model ids in generation calls.
- **Scaling controls and enterprise options:** Parallel generation limits grow by plan, and an enterprise tier provides dedicated GPUs with custom SLAs for high-volume production traffic.

**Strengths:** Single API surface for many base models and thousands of community checkpoints; No GPU provisioning, driver or model-weight maintenance on your side; Publishing-ready code samples for cURL, Python and Node per model; Transparent tiered pricing with an unlimited open-source plan and enterprise GPUs

**Limitations:** API access requires a paid subscription; the free account only unlocks the dashboard; Third-party and closed models are billed separately from the unlimited open-source plan; Call quotas are counted per request, so batch-heavy experiments can consume a plan quickly
