IBM and AMD to work on quantum-centric supercomputing

IBM and AMD announced a partnership on "quantum-centric supercomputing," pairing IBM quantum processors with AMD CPUs, GPUs, and FPGAs in hybrid classical-quantum workflows. No abstract or technical detail accompanies the item; the specifics of the architecture and timeline are not given in the source.

Why it matters: Signals that real-time classical co-processing — especially FPGA-based decoding for error correction — is becoming a commercial focus rather than a research-only concern.

Show HN: Llmswap – Python package to reduce LLM API costs by 50-90% with caching

llmswap is a Python package offering a unified client interface across OpenAI, Anthropic, Google Gemini, and local Ollama models, with opt-in response caching (TTL, memory limits, per-context isolation) and automatic provider fallback. The author claims 50-90% API cost reduction during development from cache hits on repeated prompts, and reports ~2.2k PyPI downloads. Despite the example prompt mentioning quantum computing, the package has no quantum computing content.

Why it matters: Not relevant to quantum computing research; only of general interest as an LLM developer utility.

Original abstract

I built llmswap to solve a problem I kept hitting in hackathons - burning through API credits while testing the same prompts repeatedly during development.<p>It&#x27;s a simple Python package that provides a unified interface for OpenAI, Anthropic, Google Gemini, and local models (Ollama), with built-in response caching that can cut API costs by 50-90%.<p>Key features: - Intelligent caching with TTL and memory limits - Context-aware caching for multi-user apps - Auto-fallback between providers when one fails - Zero configuration - works with environment variables<p><pre><code> from llmswap import LLMClient client = LLMClient(cache_enabled=True) response = client.query(&quot;Explain quantum computing&quot;) # Second identical query returns from cache instantly (free) </code></pre> The caching is disabled by default for security. When enabled, it&#x27;s thread-safe and includes context isolation for multi-user applications.<p>Built this from components of a hackathon project. Already at 2.2k downloads on PyPI. Hope it helps others save on API costs during development.<p>GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;sreenathmmenon&#x2F;llmswap" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;sreenathmmenon&#x2F;llmswap</a> PyPI: <a href="https:&#x2F;&#x2F;pypi.org&#x2F;project&#x2F;llmswap&#x2F;" rel="nofollow">https:&#x2F;&#x2F;pypi.org&#x2F;project&#x2F;llmswap&#x2F;</a>
