## Cortex Labs

Cortex Labs is the team behind Cortex, an open-source public blockchain whose central premise is that smart contracts should be able to run real AI models, not merely call out to off-chain servers. The Cortex Virtual Machine (CVM) is EVM-compatible, so Solidity developers keep their existing toolchain, but it also supports GPU-based inference and integer-only quantization through the MRT mechanism, letting nontrivial models execute deterministically on-chain.

The Synapse inference engine exists to solve a specific problem: guaranteeing that the same model produces exactly the same output across heterogeneous computing environments. Without determinism, on-chain AI consensus would break, which is why most projects historically pushed inference off-chain. Cortex also operates ZkMatrix, a Layer 2 zkRollup solution that batches side-chain transitions into single main-chain transactions to raise throughput and reduce the Endorphin fee per transaction.

The project aims to grow an open ecosystem in which AI researchers are incentivized to publish models to the storage layer and dApp developers can pick from competing model providers. Cortex positions itself for both areas rather than choosing one: a full blockchain with wallet, explorer, node software, and mining tooling on one side, and an AI model marketplace on the other.

**Pricing & Plans:** Cortex is free and open-source software; running nodes, mining, and deploying contracts carry only network transaction costs (Endorphin fees). There is no software license fee. Contact the team for ecosystem or partnership arrangements.

- **Cortex Virtual Machine (CVM):** An EVM-compatible execution environment that adds on-chain AI inference, using the GPU instead of the CPU to run nontrivial machine learning models.
- **Synapse deterministic inference engine:** Produces identical AI inference results across heterogeneous computing hardware, which is what allows AI to be executed on-chain without an off-chain oracle.
- **MRT quantization:** Quantization and integer-only inference techniques that make model execution efficient and reproducible inside a blockchain environment.
- **ZkMatrix Layer 2 rollup:** A zkRollup solution that aggregates side-chain transitions into a single main-chain transaction, raising TPS and lowering per-transaction fees.
- **Solidity and off-the-shelf model support:** Developers use the widely known Solidity language together with models stored on the Cortex storage layer to build AI-enhanced contracts and dApps.

**Strengths:** Makes on-chain AI inference genuinely possible instead of routing everything through off-chain oracles; EVM compatibility means Solidity developers can reuse existing skills and tooling; Deterministic inference via Synapse is the technical prerequisite for consensus on AI results; Fully open-source codebase with public developer documentation and an active community channel set

**Limitations:** On-chain AI inference is a technically demanding area with a steep learning curve; The ecosystem and available models remain smaller than mainstream smart contract platforms; Some documentation and tooling links still point to external repositories or IP-address endpoints, which can confuse newcomers

## 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
