## Caseway

Caseway positions itself as an operational AI partner rather than a model company. Instead of shipping a chatbot, it connects existing frontier models to a customer's data, governance rules, and workflows through Synthium, a validate-and-govern layer that grounds outputs in evidence, keeps audit trails, and inserts human review where policy requires it. The company describes four layers: CaseShift for data cleanup and migration, Synthium as the AI runtime, Greenlight as the audit and sign-off layer, and training for the people who make final decisions.

The products available today are practical rather than experimental. Casey handles legal research with answers cited to published court decisions in Canada and the United States. CaseForm and OmniFill read documents, apply rules, and fill court, government, and regulatory forms, with CaseForm running inside MyCase and covering more than 7,000 US forms. Caseway also mentions CaseLite, CaseBid, and Synthium as part of its demo catalog.

Engagements are enterprise-shaped: Caseway starts every relationship with a paid pilot scoped to one high-value workflow on the customer's own data, typically over four to eight weeks, followed by a hardening and deployment phase. Casey itself is free to try for seven days. Deployment options include on-premises and isolated cloud, and the company emphasizes Canadian jurisdiction and sovereign data handling for allied buyers.

**Pricing & Plans:** Casey legal research is free to try for the first 7 days; enterprise engagements begin with a paid pilot and move to deployment under revenue-share, per-usage, or partnership terms.

- **Casey legal research AI:** Returns answers grounded in millions of published court decisions covering both Canada and the United States, with citations back to the source material.
- **CaseForm and OmniFill automation:** Reads source documents, applies the relevant rules, and completes court, government, and regulatory forms, with checks before submission.
- **Synthium governance layer:** A validate-and-govern runtime that checks AI output against company rules and authority limits and holds it for sign-off when needed.
- **Audit trails and provenance:** Every output traces back to the inputs, evidence, and policy checks behind it so decisions can be defended under review.
- **Flexible sovereign deployment:** Runs on-premises or in isolated cloud environments inside a customer's security and jurisdiction constraints.

**Strengths:** Answers are traceable to cited sources, which matters for filings and regulated claims; Offers a governance and audit layer rather than handing over raw model output; Deployment flexibility including on-premises and isolated cloud for sensitive data; Integrates with Salesforce, SharePoint, Dynamics, NetSuite, SAP, and Oracle without duplicating data

**Limitations:** Enterprise engagement requires a paid pilot before full deployment; No transparent public pricing beyond the 7-day Casey trial; Value depends on data and workflow readiness, so the CaseShift data layer may be needed first

## 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
