Frequently Asked Questions
How does DeepSeek V4 "Engram Memory" work?
Engram Memory is a specialized neural cache that stores intermediate reasoning steps and long-term facts in a way that remains accessible across different chat sessions, significantly reducing the needle-in-a-haystack retrieval problem.
Is DeepSeek V4 really open source?
Yes, DeepSeek continues its commitment to open weights by releasing the full configuration and weights of the V4 model, allowing for local deployment on enterprise-grade GPU clusters.

The value outlier: an order of magnitude cheaper per task than the Western frontier, at a meaningful but not disqualifying capability gap.
Pros
- Cheapest cost per task in the scored set ($0.04)
- 1M-token context
- Open-weights heritage
Cons
- Intelligence Index (44) well behind the frontier tier
- Serving capacity has historically been constrained at peak times

Claude Opus 4.8
Claude Opus 4.8 is Anthropic's June 2026 flagship model, succeeding Opus 4.7. It posts a headline score of 81 on the hardest agentic coding and reasoning suites, holds long-horizon tool-use plans together across far more steps, and is notably more candid about its own uncertainty - refusing to fabricate rather than confidently pressing on. It is the default choice for serious agentic and software-engineering workloads.
Anthropic Mythos 1
Mythos 1 is the full release of Anthropic's specialised, security-focused system, graduating from the guarded Claude Mythos Preview. Built around Project Glasswing, it pairs frontier reasoning with defensive security tooling - vulnerability analysis, triage and incident response - deployed with heavy oversight and auditability. It runs alongside the general-purpose Claude family rather than replacing it.
