Seven GitHub repos to build an agent stack around GPT-6 Astra
The post maps seven GitHub repos — LiteLLM, Mastra, Letta, Browser Use, Guardrails, Phoenix and Continue — onto routing, memory, browsing, validation and observability around GPT-6 Astra.
1 model + 7 new GitHub repos = a completely different AI stack GPT 6 Astra can reason these repos give it routing memory browsing validation and visibility 01 LiteLLM ▸ https://github.com/BerriAI/litellm → model gateway + routing + fallbacks AGENT CORE 02 Mastra ▸ https://github.com/mastra-ai/mastra → agents + workflows + tool coordination MEMORY 03 Letta ▸ https://github.com/letta-ai/letta-code → stateful agents with persistent identity + memory BROWSER ACTIONS 04 Browser Use ▸ https://github.com/browser-use/browser-use → agents that navigate and operate real websites SAFETY 05 Guardrails ▸ https://github.com/guardrails-ai/guardrails → validate inputs outputs + trigger corrective actions OBSERVABILITY 06 Phoenix ▸ https://github.com/Arize-ai/phoenix → traces + experiments + evaluations + debugging DEVELOPER SURFACE 07 Continue ▸ https://github.com/continuedev/continue → run custom coding agents across IDE terminal + CI the architecture: request → model gateway → agent core → memory → browser actions → validation → trace → evaluate → improve the interesting part is no longer choosing one model it is choosing what surrounds the model when real work begins
