Exa 3.0 Ties Perplexity at Top of Search Index

The benchmark was run with a Stirrup agent harness and GPT-5.6 Luna (medium), so the gains reflect real agent workflows rather than single-shot queries. Teams building search-backed agents can now choose between auto mode for quality and a lite tier costing 33% less per task, both positioned on the cost-versus-capability Pareto frontier. The results put Exa level with Perplexity's Search API, giving agent developers a directly comparable alternative at published per-task prices.

Perplexity open sources SPACE agent sandbox platform under Apache 2.0

Isolating each agent task in a Firecracker microVM with externally managed credentials is a concrete, reusable pattern for agent safety that goes beyond model-level guardrails. Developers building autonomous agents can adopt SPACE directly or borrow its architecture to limit blast radius from malicious prompts. The Apache 2.0 license allows both commercial and open-source integration without restrictions.
